First class has been developed to optimize real, non- simulated systems or to find the optimal solution of a mathematical model. The methods that belong to this class include liner programming, quadratic programming and mixed-integer programming. Second class of methods has been developed to optimize a simulation model. The difference with the classical mathematical programming methods is that the objective function (which is the function to be minimized or maximized) is not known explicitly and is defined by the simulation model (computer code).

The course will demonstrate multiple approaches to build simulation models, such as discrete event simulations and agent-based simulations. Then, it will show how stochastic optimization and heuristic approaches can be used to analyze the simulated system and design a sequence of computational experiments that allow to develop a basic understanding of a particular simulation model or system through exploration of the parameter space, to find robust plausible behaviors and conditions and robust near-optimal solutions that are not prone to being unstable under small perturbations.

Prerequisite:

Bayesian analysis is especially important because it naturally allows updating the probability for a model or hypothesis as more evidence or information becomes available. This property of Bayesian approach plays significant role in dynamic analysis of a sequences of data. Applications of Bayesian analysis have exploded in recent period thanks to advances in computing techniques that made Bayesian approaches like Gibbs sampling, Markov Chain Monte Carlo, Dirichlet processes the main tools for advanced machine learning.

The focus of this course is on foundations of Bayesian approach, its applications via hierarchical models, linear and generalized linear models, mixed models and various types of Bayesian decision making.

But the biggest challenge of all is learning to think differently in order to ask new types of questions that could not be answered by analyses of less complex data streams with less complex technological infrastructure. In recent years significant progress has been achieved in creating technological ecosystems for big data analysis. Innovative technologies such as open source projects MapReduce, Hadoop, Spark, Storm, Kafka, TensorFlow, H2O, etc. allowed us to look at depths of data unseen before. We have now growing number of sources and educational courses introducing these new tools.

It appeared little more difficult to develop new data analysis methods appropriate for the new data ecosystems. There are some new interesting ideas, there is significant amount of empirical studies. But the methods of late 19^th and first half of 20^th centuries, albeit transformed to run with technology of 21^st century, are still dominating our research. Traditional and new concepts and methods of big data analysis are typically, with few exceptions, covered in books and taught in courses requiring a laptop environment, often testing limits of computing power of personal hardware, but not giving enough flavor of the 21^st century combination of high-end technology and discussion of methods in depth.

The goal of this course is to fill this gap and teach students to think about real problems by analyzing big data in new data analysis ecosystems. The course is project-based: we will take up several real life projects and discuss different approaches to digging for insights, possible pitfalls and applications. In our work on projects we will use Python and modern cloud computing environments: Spark, TensorFlow.

Reinforcement learning refers to a system or agent interacting with an environment and learning how to behave optimally in such environment. An environment typically includes time, actions, states, uncertainty and rewards. Reinforcement learning combines neuro networks and dynamic programming to find an optimal behavior or policy of the system or agent in complex environment setting. Neuro networks approximations are used to circumvent the well-known 'curse of dimensionality' which have been a barrier to solving many practical applications. Dynamic programming is the key learning mechanism that the system or the agent uses to interact with the environment and improve its performance. Students will master key learning techniques and will become proficient in applying these techniques to complex stochastic decision processes and intelligent control.

Prerequisites:

• MSCA 31007: Statistical Analysis

For data analysts to manage these changes constructively, technical skills alone are not sufficient. Understanding the challenging ethical issues big data presents needs to supplement technical competence.

This four-session course will focus on two of the more critical big data ethical issues at hand: bias and privacy. Its goal is to equip students with the ability to identify, understand, and discuss these the ethics of bias and privacy in the context of their work.

The course is offered on a pass/fail basis and employs lecture, discussion, guest speakers, case studies, mock debates, and brief videos as pedagogical techniques.

There is no required reading for the course, although a list of sources and relevant readings will be provided. Students will be expected to participate actively in classroom discussion and activities. One of those activities will be a series of four classroom debates.

Big data analytics has generated significant change in industries such as manufacturing, health care, transportation, and retail, as well as in government and social services. For data analysts to manage these changes constructively, technical skills alone are not sufficient. Understanding the challenging ethical issues big data presents needs to supplement technical competence.

At the same time, Big Data and data analytics have raised numerous ethical questions about how data is collected, how data analytics methods transform that data into predictive information, and how that information is then used. This 3-hour seminar will introduce you to the benefits of Big Data and data analytics as well as the ethical challenges they raise. We will examine the rise of Big Data and data analytics as a fundamental paradigm shift in human inquiry; review ethical frameworks that help contextualize conversations about the benefits and challenges of Big Data and data analytics; study challenges related to privacy, anonymity, bias, and disparate impact; compare regulatory environments in the U.S., European Union, India, and China; and study how one large corporation has wrestled with its own Big Data and data analytics ethical challenges.

The core areas of research will focus in on how to discover your personal strengths and passions, explore the broad array of jobs that data scientists advance through, and also focus on the companies that may be the best fit for the next stages of each student's career. The focus developed through this research will help prepare the student for the data science marketplace, present themselves confidently, and accelerate the students professional successful career search process.
