In industrial applications related to production processes and virtual product design, one is often interested in combining data-driven modeling and optimization to support decision making in an efficient way. Using data driven models in combination with optimization is also called prescriptive analytics and has important applications in Industry 4.0.
In this tutorial, we discuss various aspects of such a combination of data driven modeling and optimization, including multi-objective optimization. For costly applications (e.g., in terms of time), this combination is embodied by methods such as efficient global optimization (EGO) and Bayesian global optimization, since they are able to produce good solutions using a small budget of function evaluations. Such methods rely on supervised machine learning methods for building a nonlinear regression model of the objective function, such that they are directly related to data driven modeling algorithms. In this context, Gaussian process regression is widely used, and we explain such an approach as well as its extension, cluster Kriging, for dealing with large data sets efficiently. Based on this, we will discuss the multi-objective extension to EGO, which greatly supports the decision- making process.
In the unsupervised machine learning domain, methods for anomaly detection have recently gained increasing interest in many real-world applications. We discuss a new method for anomaly detection in high-dimensional data and illustrate applications of anomaly detection in the automotive industry. Other applications include the combination of simulation and optimization, where efficient global optimization is also a very powerful approach. The tutorial concludes by giving an outlook on applications Industry 4.0, with examples from steel production and automotive industry.

There are a large number of ways that machine learning is advancing biology, biotech and medicine. A key grand challenge in biology is the annotation of genomes. We sequence large numbers of genomes for diverse reasons: from diagnosing and tailoring treatment for diseases to cataloging and mining biodiversity. We will dive deeply into the problem of predicting the function of proteins and protein families. This is a good illustrative problem at the intersection of biology and ML for several reasons: 1) input data is diverse with networks, sequences, and 3 dimensional structures all in great abundance, 2) protein function is organized into a hierarchy of many thousands of labels, both organized and challengingly rich, and 3) the potential for positive impact is quite high with applications from bioremediation, biosynthesis, ecology, and medicine.
Familiarity with statistics and basic concepts of machine learning. Biology will be introduced and biology knowledge is not needed, but it couldn't hurt to read up on basic concepts like sequence alignment, biological sequence databases, and protein structure.

Apache spark, open-source cluster-computing framework providing a fast and general engine for large-scale processing, has been one of the exciting technologies in recent years for the big data development. The main idea behind this technology is to provide a memory abstraction which allows us to efficiently share data across the different stages of a map-reduce job or provide in-memory data sharing. Our lecture starts with a brief introduction to Spark and its ecosystem, and then shows some common techniques - classification, collaborative filtering, and anomaly detection, among others, to fields particle physics, genomics, social media analysis, web-analytics and finance. If you have an entry-level understanding of machine learning and statistics, and program in Python or Scala, you will find these subjects useful for working on your own big data projects.

Network-based representation has quickly emerged as the norm in representing rich interactions among the components of a complex system for analysis and modeling. It is thus critical for the network to truly represent the inherent phenomena in the complex system to avoid incorrect analysis results or conclusions. For a variety of complex systems, representing them with the conventional first-order (Markov property) networks, which is the norm, captures only the first order relationship connections in the underlying data, missing the variable and higher order of dependencies that might be driving the system. An accurate network representation of the underlying data is a prerequisite for reliable analyses that build upon the network. The limited representation of the first-order network can lead to inaccurate results that rely on the network representation of the underlying data. This has spurred recent research that goes beyond the dyadic interactions to higher and variable orders of interactions to more accurately construct the network representation of the underlying data from a complex system.
The goal of this tutorial is to provide an introduction to higher order networks and related techniques; and on representation learning for networks (inclusive of higher order and first order networks).

Ethical and Social Implications of AI
The introduction of AI in the midst of society has created new opportunities and new challenges, that include deep issues of fairness, transparency, and human autonomy. The solution of those new problems cannot be just technical, but there is a role for technical solutions too, within a more general effort to understand what can be done - so that we can safely coexist with intelligent machines in a data-driven society.
Social Media Analysis
The analysis of social media content can reveal new information about society, public opinion and even possibly biology. We review recent work that is based on statistical text mining, and that integrates various signals to reveal novel psychological and behavioural patterns in large populations.
News Content Analysis
The analysis of media content, both present and historical, can reveal new insights about trends, biases and events, that would otherwise be difficult to analyse. We show a series of examples - starting with the digitisation process and ending with the creation of maps and timelines - illustrating how big data and digital humanities can meet and provide new help for historians.

Big data problems can be classified into three main categories: batch processing (Hadoop), stream processing (Apache Flink and Apache Heron) and iterative machine learning and graph problems (Apache Spark). Each of these problems have different processing, communication and storage requirements. Therefore, each system provides separate solutions to these needs.
All these systems use dataflow programming model to perform distributed computations. With this model, big data frameworks represent a computation as a generic graph where nodes doing computations and the edges representing the communication. The nodes of the graph can be executed on different machines in the cluster depending on the requirements of the application.
We identify four key tasks in big data systems:
Twister2 [1-3] is a loosely-coupled component-based approach to big data. Each of the four essential abstractions have different implementations to support various applications. Therefore, it has a pluggable architecture. It can be used to solve all three types of big data problems mentioned above.
In this tutorial, we review big data problems and systems, explain Twister2 architecture and features, provide examples for developing and running applications on Twister2 system. By learning Twister2, big data developers will have an experience with a flexible big data solution that can be used to solve all three types of big data problems.

There is a tremendous amount of data spread across the web and stored in databases that can be turned into an integrated semantic network of data, called a knowledge graph. Knowledge graphs have been applied to a variety of challenging real-world problems including combating human trafficking by analyzing web ads, identifying illegal arms sales from online marketplaces, and predicting cyber attacks using data extracted from both the open and dark web. However, exploiting the available data to build knowledge graphs is difficult due to the heterogeneity of the sources, scale in the amount of data, and noise in the data. In this course I will present the techniques for building knowledge graphs, including extracting data from online sources, cleaning and transforming the data, aligning the data to a common terminology,and linking the data across sources, and constructing and querying knowledge graphs at scale.
Background in computer science and some basic knowledge of AI, machine learning, and databases will be helpful, but not required.

COURSE DESCRIPTION: Applying Finite Mixture Models to Big Data
Attention is focussed initially on the role of finite mixture models in modelling and clustering heterogeneous data. The use of the EM algorithm to fit mixture distributions via maximum likelihood is reviewed. Extensions of the commonly used normal (Gaussian) mixture models are considered through the use of hidden variables to formulate various skew component distributions suitable for representing clusters in the presence of skewness and kurtosis. Also, hidden variables in the form of latent factors are adopted to fit mixtures of factor analyzers in situations where the dimension of the feature data are large relative to the data within a cluster. Consideration is given to further extensions of this approach to handle big data of possibly high-dimensions after an appropriate reduction where necessary in the number of variables. This latter reduction in the first instance is effected by a clustering of the variables via mixtures of linear mixed models. There is coverage also of deep normal mixtures to increase the flexibility of these models. Another role of mixture models addressed is their use for controlling the false positive rate in multiple comparisons and testing. The statistical methodology to be presented is to be highlighted by consideration of several real-data examples from various fields, including flow cytometry, bioinformatics, and image analysis.
Role of mixture distributions in modelling and clustering heterogeneous data; maximum likelihood fitting of mixture models via the EM algorithm; Normal (Gaussian) mixture models and extensions for clusters in the presence of skewness and kurtosis; mixtures of linear mixed models; mixtures of factor analyzers for high-dimensional data; deep mixture factor analyzers; role of mixture models in controlling the false discovery rate in multiple comparisons and testing; applications of the aforementioned methodology to data from flow cytometry, microarray analyses, magnetic resonance imaging, and other various studies.
Participants are expected to have a knowledge of Statistics at a level corresponding to at least the third year of a three-year undergraduate course in Science. Background knowledge particularly useful for this Course can be obtained from the two monographs McLachlan and Krishnan (2008, The EM Algorithm and Extensions. Second Edition, Wiley) and McLachlan and Peel (2000, Finite Mixture Models, Wiley). This material, however, will be briefly reviewed.
Geoff McLachlan is Professor of Statistics in the School of Mathematics and Physics at the University of Queensland. His research in Statistics is in the related fields of classification, cluster and discriminant analyses, image analysis, machine learning, neural networks, and pattern recognition, and in the field of statistical inference. The focus in the latter field has been on the theory and applications of finite mixture models and on estimation via the EM algorithm. A common theme of his research in these fields has been statistical computation, with particular attention being given to the computational aspects of the statistical methodology. He has written over 270 peer-reviewed research articles which have received over 40,000 citations. He has written six monographs on discriminant analysis (McLachlan, 1992), mixture models (McLachlan and Basford, 1988; McLachlan and Peel, 200), the EM algorithm (McLachlan and Krishnan, 1997 & 2008); and the analysis of gene expression data (McLachlan, Do, and Ambroise; 2004). He is currently an associate editor of several journals including Advances in Data Analysis and Classification, BMC Bioinformatics, Journal of Classification, Statistics and Computing, and Statistical Modelling. He is a former president of the International Federation of Classification Societies (IFCS). He is a fellow of the Australian Academy of Science and also a fellow of the American Statistical Association and the Royal Statistical Society. For 2007 to 2011 he was an Australian Research Council Professorial Fellow. He has received several awards, including the Pitman Medal of the Statistical Society of Australia in 2010, the IEEE ICDM Research Contributions Award in 2011, and the IFCS Research Medal for Outstanding Research Achievements in 2017.
Executing scientific workflows at scale poses a significant challenge to many teams and institutions, we present a unified system for portable, reproducible execution on local and remote resources.
The Skyport system  provides containerized workflow execution with Docker  across systems boundaries. Allowing researchers to execute scientific workflows across system boundaries using the AWE [1, 3, 4] workflow engine and the SHOCK  as an active object store. AWE and SHOCK are implemented a RESTful service for managing and executing workflows, workflows are specified in Common workflow language (CWL) format.
CWL is a single, multi-vendor language to describe scientific workflows created by a community of practitioners. In addition to being multi-vendor – and thus supporting multiple engines for computing --, another critical feature of CWL is the separation of science content and computational implementation. This allows experts in each of the domains to focus on their area (CWL, http://commonwl.org).
One large scale use case driving the development of Skyport is MG-RAST [7, 8] (https://www.mg-rast.org), a hosted data analytics system used by over 40,000 researchers all over the planet.
The assumption is that participants will bring a laptop with the ability to execute multiple Docker containers. Participants should test their available memory and hard drive space. Software systems required:
The participants will be asked to install software (via Docker), modify configuration files and perform other Unix command line style activities.

Big Data applications generically require the use of flexible, hence high-dimensional, statistical models to capture meaningful patterns in the data, and this usually leads to challenging non-linear and non-convex global optimization problems. The large data volume that must be handled further increases their difficult nature. This course will introduce methods from the field of computational swarm intelligence (SI), with the focus being on an in-depth presentation of Particle Swarm Optimization (PSO), that have proven useful in solving such optimization problems. PSO is a metaheuristic inspired by observations of cooperative behavior in multi-agent biological systems. It shows a remarkable robustness across a wide range of optimization problems, reducing the burden that is generally involved in tuning stochastic global optimization algorithms. The course will use concrete problems to illustrate the application of PSO to statistical regression and address practical issues that are often encountered in creating a successful implementation.
The following is a list of the main topics to be covered in the course.
None, as this is an introductory course. However, familiarity with basic probability theory and statistics will be a plus.
Soumya D. Mohanty, Professor of Physics at UTRGV, completed his PhD degree in 1997 at the Inter-University Center for Astronomy and Astrophysics, India. He subsequently held post-doctoral positions at Northwestern University, Penn State, and the Max-Planck Institute for Gravitational Physics. He was also a visiting scholar with the LIGO project at Caltech. Mohanty's research has focused on solving some of the important data analysis challenges faced in the realization of Gravitational Wave (GW) astronomy across all observational frequency bands.

His work has been funded by grants from the Research Corporation, the U.S. National Science Foundation, and NASA.
The lecture has two parts. Beginning with the role of pattern recognition in data mining and machine intelligence, it describes the various components of granular computing (GrC), information granules, significance of fuzzy sets and rough sets in GrC and its relevance in mining large data sets. Uncertainty modelling in fuzzy-rough framework, including generalised entropy measures, concerning data analytics is emphasized.
The second part deals with some mining applications such as, video tracking in ambiguous situations, selection of genes and miRNAs in bioinformatics, and community detection, target set selection and link prediction in social networks. All these data possess Big data characteristics. Roles of different kinds of granules, f-information measures and rough lower approximation in mining are demonstrated. Significance of lower approximation for knowledge encoding in designing granular neural networks, estimating the object model in unsupervised tracking, and determining the probability of definite and doubtful regions in cancer classification is illustrated. Finally, the concept of perception granules in natural language understanding and the use of z-numbers in abstracting various semantic-precisiations are explained. New terms like generalized rough entropy, granular flow graph, rough filter, intuitionistic entropy, granular social network model, fuzzy-rough community, double bounded rough sets, and z*-numbers are defined.
Several examples are provided to explain the aforesaid concepts. The talk concludes mentioning the challenging issues and the future directions of research including the significance in computational theory of perception, natural computing and in granulated deep learning.

Ensemble learning imitates our second nature to seek several opinions before making a crucial decision. The core principle is to weigh several individual models and combine them in order to reach a decision or prediction that is better than the one obtained by each of them separately. Researchers from various disciplines have explored the use of ensemble methods since the late seventies.
This short course aims to provide a methodical and coherent presentation of classical ensemble methods as well as extensions and novel approaches that were recently introduced. Along with algorithmic descriptions of each method, we will provide a description of the settings in which this method is applicable and the trade-offs incurred by using the method.

The course presents data analysis techniques based on the theory of coupled oscillators and aimed at reconstruction of the network structure and inference of nodes properties from observations. The approach assumes that the multi-variate time series under study are outputs of weakly-coupled self-sustained oscillators and that the signals are appropriate for phase estimation. Therefore, the course will begin with a short introduction into the theory of interacting oscillators and there synchronization. We will discuss effects of phase and frequency locking and illustrate them with numerous examples. Next, we will discuss how this ideas can be used in data analysis. The main idea is to infer a model for phase dynamics of the observed network. Hence, the first step is to estimate phases from time series, and this step will be discussed in details. Then we will proceed with an analysis of the phase model with the goal to obtain the strength of directed links and infer the network structure. Thus, our technique represents an approach to the connectivity problem, relevant for physiology, neuroscience, and other fields. We demonstrate that our technique provides effective phase connectivity which is close, though not identical to the structural one. However, for weak coupling we achieve a good separation between existing and non-existing connections. We also discuss how the frequencies and phase response curves of interacting units can be estimated. Next, we extend the approach to cover the case of pulse-coupled neuron-like units, where only times of spikes can be registered, so that the data represent point processes. We will also demonstrate how the inferred phase model can predict synchronisation domains in experiments.

The representation of multidimensional, spatial, and metric data is an important issue in applications of spatial and spatiotextual databases, geographic information systems (GIS), and location-based services. Recently, there has been much interest in hierarchical data structures such as quadtrees, octrees, and pyramids which are based on image hierarchies, as well methods that make use of bounding boxes which are based on object hierarchies. Their key advantage is that they provide a way to index into space. In fact, they are little more than multidimensional sorts. They are compact and depending on the nature of the spatial data they save space as well as time and also facilitate operations such as search.
We describe hierarchical representations of points, lines, collections
of small rectangles, regions, surfaces, and volumes. For region data,
we point out the dimension-reduction property of the region quadtree
and octree. We also demonstrate how to use them for both raster and
vector data. For metric data that does not lie in a vector space so
that indexing is based simply on the distance between objects, we
nreview various representations such as the vp-tree, gh-tree, and
mb-tree. In particular, we demonstrate the close relationship
between these representations and those designed for a vector space.
For all of the representations, we show how they can be used to compute nearest objects in an incremental fashion so that the number of objects need not be known in advance. The VASCO JAVA applet is presented that illustrates these methods (found at http://www.cs.umd.edu/~hjs/quadtree/index.html). They are also used in applications such as the SAND Internet Browser (found at http://www.cs.umd.edu/~brabec/sandjava).
The above has been in the context of the traditional geometric
representation of spatial data, while in the final part we review the
more recent textual representation which is used in location-based
services where the key issue is that of resolving ambiguities.
For example, does
London'' correspond to the name of a person or a location, and if it corresponds to a location, which of the over 700 different instances ofLondon'' is it. The NewsStand system at
newsstand.umiacs.umd.edu and the TwitterStand system at
TwitterStand.umiacs.umd.edu system are examples. See also the

What is the statistically optimal way to detect and extract information from signals in noisy data? After detecting ensembles of signals, what can we learn about the population of all the signals? This course will address these questions using the language of Bayesian inference. After reviewing the basics of Bayes theorem, we will frame the problem of signal detection in terms of hypothesis testing and model selection. Extracting information from signals will be cast in terms of computing posterior density functions of signal parameters. After reviewing model selection and parameter estimation, the course will focus on practical methods. Specifically, we will implement sampling algorithms which we will use to perform model selection and parameter estimation on signals in synthetic data sets. Finally, we will ask what can be learned about the population properties of an ensemble of signals. This population-level inference will be studied as a hierarchical inference problem.

Social Computing is an emerging discipline, and just like any discipline at a nascent stage it can often mean different things to different people. However, there are three distinct threads that are emerging. First thread is often called Socio-Technical Systems, which focuses on building systems that allow large scale interactions of people, whether for a specific purpose or in general. Examples include social networks like Facebook and Google Plus, and Multi Player Online Games like World of Warcraft and Farmville. The second thread is often called Computational Social Science, whose goal is to use computing as an integral tool to push the research boundaries of various social and behavioral science disciplines, primarily Sociology, Economics, and Psychology. Third is the idea of solving problems of societal relevance using a combination of computing and humans. The three modules of this course are structured according to this description. The goal of this course is to discuss, in a tutorial manner, through case studies, and through discussion, what Social Computing is, where it is headed, and where is it taking us.
• Module 1: Socio-technical systems
• Introduction to Social Computing
• Socio-technical systems
• Applying data mining to social computing systems
• Module 2: Computational Social Science
• Online trust
• Social influence
• Individual and group/team performance
• Identifying and preventing bad behavior
• Module 3: Solving Problems of Societal Relevance
• Social computing for humanitarian assistance
• Wrap-up discussion
• Privacy and ethics
• Where are we headed
To be provided later.
This course is intended primarily for graduate students. Following are the potential audiences:

Longitudinal data is obtained when a time-sequence of measurements is made on a response variable for each of a number of subjects in an experimental or observational study. In such cases, individuals usually display a high degree of similarity in responses over time and, thus, classical regression models are inadequate. This course is aimed at giving its attendees insights into the theoretical concepts and practical experience into the models used for analysis of longitudinal data, particularly mixed-effect models. It will provide an introduction to (1) the theoretical foundations of mixed models, 2) a guide to build, examine, interpret and compare mixed-effect models as well as to conduct hypothesis testing and (3) the necessary resources to conduct a wide range of longitudinal analyses. All practical exercises will be conducted in R. Participants are encouraged to bring datasets to the course and apply the principles to their specific areas of research.
Students must be familiar with basic R functions to read and manipulate data and generate basic data plots. Familiarity with statistical concepts and basic understanding of regression and anova. An installed version of R (https://cran.r-project.org/) and R-Studio (https://www.rstudio.com/) on a laptop for completing exercises.

Her long terms goals are to develop robust statistical techniques to mine and integrate complex high-throughput data, tailored to specific disease models, with an emphasis on immunological diseases and to develop precision medicine algorithms to predict treatment response and phenotype.
We shall study algorithms that have been found useful in querying large dataswets. The emphasis is on algorithms that cannot be considered "machine learning."
A course in algorithms at the advanced-undergraduate level is important. A course in database systems is helpful, but not required.
We will be covering (parts of) Chapters 3, 4, 5, and 10 of the free text: Mining of Massive Datasets by Jure Leskovec, Anand Rajaraman, and Jeff Ullman, available at www.mmds.org

In this mini-course, I’m going to explain a powerful approach that has been used in many industrial cases for complex design optimisations. Surrogate data-driven models help to build a balanced model of a complex process or an object. Later on, those models can be used during the study of a complex object or a process properties in a computationally efficient way. The same method can be applied to several scientific cases ranging from new detector design and theory parameters estimation to the substitution of the slow simulator by a faster neural network. I'll present an overview of the method and several industrial and scientific examples: design of an active muon shield for SHiP experiment and fast tuning of Pythia parameters. The course includes both theoretical part and practical hands-on exercises.

Process mining is the missing link between model-based process analysis and data-oriented analysis techniques. Through concrete data sets and easy to use software the course provides data science knowledge that can be applied directly to analyze and improve processes in a variety of domains.
The course explains the key analysis techniques in process mining. Participants will learn various process discovery algorithms. These can be used to automatically learn process models from raw event data. Various other process analysis techniques that use event data will be presented. Moreover, the course will provide easy-to-use software, real-life data sets, and practical skills to directly apply the theory in a variety of application domains.
Process mining provides not only a bridge between data mining and business process management; it also helps to address the classical divide between "business" and "IT". Evidence-based business process management based on process mining helps to create a common ground for business process improvement and information systems development.
Note that Gartner recently identified process mining software as a new and important class of software. Currently, there are over 25 vendors providing commercial process mining tools and a rapid uptake of the new technology is expected.
The course focuses on process mining as the bridge between data science and process science. The course will introduce the three main types of process mining.
The course uses many examples using real-life event logs to illustrate the concepts and algorithms. After taking this course, one is able to run process mining projects and have a good understanding of the Business Process Intelligence field.
This course is aimed at both students (Master or PhD level) and professionals. A basic understanding of logic, sets, and statistics (at the undergraduate level) is assumed. Basic computer skills are required to use the software provided with the course (but no programming experience is needed). Participants are also expected to have an interest in process modeling and data mining but no specific prior knowledge is assumed as these concepts are introduced in the course.
