Statistics & Computer Science

STCS GR5705  Introduction to Data Science

Professor Tian Zheng (Syllabus

Data Science is a dynamic and fast growing field at the interface of Statistics and Computer Science. The emergence of massive datasets containing millions or even billions of observations provides the primary impetus for the field. Such datasets arise, for instance, in large-scale retailing, telecommunications, astronomy, and internet social media. This course will emphasize practical techniques for working with large-scale data. Specific topics covered will include statistical modeling and machine learning, data pipelines, programming languages, "big data" tools, and real world topics and case studies. The use of statistical and data manipulation software will be required. Course intended for non-quantitative graduate-level disciplines. This course will not count towards degree requirements for graduate programs such as Statistics, Computer Science, or Data Science. Students should inquire with their respective programs to determine eligibility of course to count towards minimum degree requirements. This course does not fulfill any major requirements for undergraduate degree programs offered by Computer Science. Note: this course was formerly STAT W4242.

In addition to the DSI elective courses, MS students are encouraged to explore courses offered across the university and take advantage of the expertise in a wide range of disciplines at Columbia. Prior to registration, students receive advisement to determine if a course of interest is relevant and meets the criteria of a 4000-level or higher, technical course completed for a letter grade. You're welcome to explore the CU Directory of Classes for possible courses: http://www.columbia.edu/cu/bulletin/uwb/

The following courses are examples of classes that MS students have used for elective credit. Elective courses and schedules are dependent on faculty availabilty and may vary each semester. Past course offerings are not guaranteed to be offered in the future.

Please note that many departments, including DSI, give registration priority to their students. Space permitting, courses are then opened up to students outside the department.
 

DSI Electives

COMS W4995 Topics in Computer Science: Applied Machine Learning

Professor Andreas Mueller (Syllabus)

This class offers a hands-on approach to machine learning and data science. The class discusses the application of machine learning methods like SVMs, Random Forests, Gradient Boosting and neural networks on real world dataset, including data preparation, model selection and evaluation. This class complements COMS W4721 in that it relies entirely on available open source implementations in scikit-learn and tensor flow for all implementations. Apart from applying models, we will also discuss software development tools and practices relevant to productionizing machine learning models.

 

COMS W4995 Topics in Computer Science: Applied Deep Learning

Professor Josh Gordon (Syllabus)

This course provides a practical, hands-on introduction to Deep Learning. We aim to help students understand the fundamentals of neural networks (DNNs, CNNs, and RNNs), and prepare students to successfully apply them in practice. This course will be taught using open-source software, including TensorFlow 2.0. In addition to covering the fundamental methods, we will discuss the rapidly developing space of frameworks and applications, including deep learning on the web. This course includes an emphasis on fairness and testing, and teaches best practices with these in mind.

 

COMS W4995 Topics in Computer Science: Causal Inference for Data Science

Instructor Adam Kelleher (Syllabus)

Data scientists often have to answer questions that will lead to decisions about actions a company might take. Often, they will be able to run an experiment, and see the effect the decision might have by testing it first.  Other times, they will only have observational data at their disposal. In both cases, they need to infer the causal effect of an action on some outcomes of interest. Causal inference is an essential skill for a data scientist. Without a proper understanding, potential biases as large as 1000% have been observed in practice! This course will cover the basics of the potential outcomes framework, the Pearlian framework, and a collection of methods for observational and experimental causal inference. We'll use examples from industry applications throughout the course, especially focused on web applications.

 

COMS W4995 Topics in Computer Science: Data-Analytics Pipeline

Instructor Adam Kelleher 

"Data analytics pipeline" focuses on the intersection between data science, data engineering, and agile product development. In this course you'll learn some common data generating processes, how the data is transported to be stored, how analytics and compute capabilities are built on top of that storage, and how production machine learning and modeling platforms can be built in that context. There is a strong focus on good architecture design patterns, and practical implementation considerations that focus on delivering results over building perfect systems

 

 

COMS W4995 Topics in Computer Science: Elements of Data Science

Instructor: Bryan Gibson

This course is designed as an introduction to elements that constitutes the skill set of a data scientist. The course will focus on the utility of these elements in common tasks of a data scientist, rather than their theoretical formulation and properties. The course provides a foundation of basic theory and methodology with applied examples to analyze large engineering, business, and social data for data science problems. Hands-on experiments with R or Python will be emphasized.

 

 

COMS E6998 Topics in Computer Science: Machine Learning with Probabilistic Programming

Instructor:  Alp Kucukelbir (Syllabus)

The world is full of noise and uncertainty. To make sense of it, we collect data and ask questions. Is there a tumor in this x-ray scan? What affects the quality of my manufacturing plant? How old is this planet I see through the telescope? Does this drug actually work? To pose and answer such questions, data scientists must iterate through a cycle: probabilistically model a system, infer hidden patterns from data, and evaluate how well our model describes reality. By the end of this course, you will learn how to use probabilistic programming to effectively iterate  through this cycle. Specifically, you will master

  • modeling real-world phenomena using probability models,
  • using advanced algorithms to infer hidden patterns from data, and
  • evaluating the effectiveness of your analysis.

You will learn to use (and perhaps even contribute to) Edward throughout this course.

 

 

COMS E6998 NLP: Computational Models of Social Meaning

Instructor: Smaranda Muresan (Syllabus)

  1. Sentiment Analysis: automatic detection of people’s sentiment towards a topic, event, product, or persons. Practical applications in various domains will be discussed (e.g., predicting stock market prices, or presidential elections)
  2. Emotion and Mood Analysis: automatic detection of people’s emotions (angry, sad, happy) by analyzing various media such as books, emails, lyrics, online discussion forums. Practical applications in various domains (such as predicting depression, categorization of songs)
  3. Belief Analysis and Hedging: automatic detection of people’s beliefs (committed belief and non-committed beliefs) from social media. Analysis of the use of hedging as a communicative device in various media: online discussions, scientific writing or legal discussions.
  4. Deception Detection (e.g., detecting fake reviews online, or deceptive speech in court proceedings)
  5. Argumentation Mining: automatic detection of arguments from text, such as online discussion or persuasive essays. Practical application for various domains (e.g., political, legal or education (e.g., improving students’ skills in writing persuasive essays)
  6. Social Power: automatic detection of power structure in organizations by analyzing people’s communications such as emails.

EECS E6894 Topics in Information Processing: Deep Learning for Computer Vision, Speech, and Language

 

 

IEOR E4571 Topics in Operations Research: Personalization Theory & Application

Instructor: Brett Vintch

Personalization is a key tool for enhancing customer experience across industries, thereby driving user loyalty and customer value. It is therefore no surprise that creating and enhancing personalization systems is also increasingly one of the core responsibilities of data science teams, and a key focus for many of the machine learning algorithms in the sector.

This course will focus on common personalization algorithms and theory, including behavior-based and content-based recommendation, commonly encountered issues in scaling and cold-starts, and state of the art research. It will also look at how businesses use, and misuse, these techniques in real world applications.

 

IEOR E4721 Topics in Quantitative Finance: Big Data in Finance

Professor Miquel Noguer Alonso (Syllabus)

The vast proliferation of data and increasing technological complexities continue to transform the way industries operate and compete. Over the last two years, 90 percent of the data in the world has been created as a result of the creation of 2.5 quintillion bytes of data on a daily basis. Commonly referred to as big data, this rapid growth and storage creates opportunities for collection, processing and analysis of structured and unstructured data. Financial services, in particular, have widely adopted big data analytics to inform better investment decisions with consistent returns. In conjunction with big data, algorithmic trading uses vast historical data with complex mathematical models to maximize portfolio returns. The continued adoption of big data will inevitably transform the landscape of financial services. However, along with its apparent benefits, significant challenges remain in regards to big data’s ability to capture the mounting volume of data. The increasing volume of market data poses a big challenge for financial institutions. Along with vast historical data, banking and capital markets need to actively manage ticker data. Likewise, investment banks and asset management firms use voluminous data to make sound investment decisions. Insurance and retirement firms can access past policy and claims information for active risk management. The course will be a mix of Theory and practice with real big data cases in finance. We will invite guest lecturers mostly for real Big Data Finance Applications. We will give MATLAB, R or Python examples.

 

STATS GR5293 Topics in Modern Statistics: Applied Machine Learning for Financial Modeling and Forecasting

Instructor: Michel Leonard

The course focuses on translating technical expertise into work-place solutions by teaching students to: (1) identify relevant shortfalls in  traditional processes; (2) precisely match datasets and machine learning features to overcome these shortfalls; (3) narrowly define value to fit work place processes, analytical framework, and bottom line.  Each class will be structured as an actual end-to-end work-place project and use concrete examples to teach students to design, build and deliver solutions  that integrate these considerations. A combination of assignments, presentation, and research paper will be sued to evaluation students' progress in bridging technical and applied solutions with evaluation criteria matching those of a work-place project.

 

STATS GR5293 Topics in Modern Statistics: Applied Machine Learning for Image Analysis

Instructor: Xiaofu He

Images are everywhere. How to deal with image data, especially with big data, is an urgent problem for data analysts.  Machine learning has proven to be a powerful technology to process and analyze such big data.  The course will discuss how machine learning methods are use in the field of image analysis, including biometrics (iris and face recognition), natural images (object identification/recognition), brain images (encoding and decoding), and handwritten digit recognition.  Students will learn how to sue traditional machine learning methods in image data processing and analysis, and develop techniques to improve these methods.  The aim of this course is to prepare students with basis knowledge and skills to explore opportunities using machine learning in the field of image analysis.
