DATA 30100. Introduction to Data Science. 100 Units.

The course will focus on the analysis of real life data and on statistical and machine learning methods to perform inference and to predict future outcomes. It will cover topics from the whole data life cycle, ranging from data collection (including wrangling, cleaning, and sampling) to summarizing results through visualization and interpretable summaries, with a focus on extracting meaning, value and information from data. Important aspects in data science, such as bias, fairness, privacy while building algorithms and predictive models, will also be explored.

DATA 30332. Thinking with Deep Learning for Complex Social & Cultural Data Analysis. 100 Units.

A deluge of digital content is generated daily by web-based platforms and sensors that capture digital traces of human communication and connection, and complex states of society, culture, economy, and the world. Emerging deep learning methods enable the integration of these complex data into unified social and cultural "spaces" that enable new answers to classic social and cultural questions, and also pose novel questions. From the perspective of deep learning, everything can be viewed as data-novels, field notes, photographs, lists of transactions, networks of interaction, theories, epistemic styles-and our treatment examines how to configure deep learning architectures and multi-modal data pipelines to improve the capacity of representations, the accuracy of complex predictions, and the relevance of insights to substantial social and cultural questions. This class is for anyone wishing to analyse textual, network, image or arbitrary structured and unstructured data, especially in concert with one another to solve complex social and cultural analysis problems (e.g., characterize a culture; predict next year's ideology).

Instructor(s): James Evans     Terms Offered: Spring
Prerequisite(s): The course uses Python and the widely popular PyData ecosystem to demonstrate all motivating examples and includes working code, accompanying exercises, relevant datasets and additional analytics and visualization that facilitate social and cultural interpretation and communication. Familiarity with Python is required.

DATA 31500. Data Interaction. 100 Units.

This course provides core knowledge and technical skills around data interfaces, with an emphasis on visualization and front-end software development. Graduate students in Data Science and Computer Science will engage in project-based learning to become fluent with visualization APIs, computational notebooks, web development, technical writing, and presentation. Topics of interest include data visualization design, spatial and visual reasoning, cartography, interactive articles, data storytelling, data-driven persuasion, uncertainty communication, and model interpretability.

DATA 33221. Advanced Topics in Law and Computing. 100 Units.

This interdisciplinary seminar will bring together instructors and graduate students from Computer Science / Data Sciences and the Law School. The seminar's focus will be on topics where law and policy intersect with computer science. Such topics may include cryptography and encryption; electronic surveillance and criminal procedure; the Computer Fraud & Abuse Act; the law governing data breaches; redistricting and the US Census; deep fakes; GDRP, Europe's Digital Services Act and the CCPA; and international data transfers. Students will be evaluated on the basis of short bi-weekly reaction papers, class participation based on weekly assigned reading, and team projects that pair law students with computer and data scientists.

DATA 34100. Introduction to Data Systems and Data Design. 100 Units.

The goal of this course is to teach students: (1) how to think about data , its logical semantics, and what is a query; (2) how to practically handle data, both in relational databases and other more flexible data processing frameworks (e.g. Spark); (3) practical design principles about schema, integrity constraints, etc. (4) an introduction to systems that allows students to understand performance, and helps them become better users.

DATA 35422. Machine Learning for Computer Systems. 100 Units.

This course will cover topics at the intersection of machine learning and systems, with a focus on applications of machine learning to computer systems. Topics covered will include applications of machine learning models to security, performance analysis, and prediction problems in systems; data preparation, feature selection, and feature extraction; design, development, and evaluation of machine learning models and pipelines; fairness, interpretability, and explainability of machine learning models; and testing and debugging of machine learning models. The topic of machine learning for computer systems is broad. Given the expertise of the instructor, many of the examples this term will focus on applications to computer networking. Yet, many of these principles apply broadly, across computer systems. You can and should think of this course as a practical hands-on introduction to machine learning models and concepts that will allow you to apply these models in practice. We'll focus on examples from networking, but you will walk away from the course with a good understanding of how to apply machine learning models to real-world datasets, how to use machine learning to help computer systems operate better, and the practical challenges with deploying machine learning models in practice."

DATA 37000. Introduction to Machine Learning and Neural Networks. 100 Units.

This course is an introduction to machine learning (ML) for students to build a solid foundation in modeling and data science. It will cover both unsupervised and supervised ML algorithms, with the latter focusing on both regression and classification models. Python is the programming language of choice for implementing various models to solve complex problems across multiple domains. The course will also introduce basic neural network architectures, including Single-Layer Perceptron (SLP), Convolutional Neural Networks (CNN), and Recurrent Neural Networks (RNN). Students will apply these techniques in contexts where they are most effective. A strong understanding of linear algebra, multivariable calculus, and statistics/probability theory is expected. Python coding assignments and projects will be integral to the course.

DATA 37711. Foundations of Machine Learning and AI - Part I. 100 Units.

This course is an introduction to machine learning targeted at students who want a deep understanding of the subject. Topics include modern approaches to supervised learning, unsupervised learning, and the use of machine learning in estimating real-world effects. In principle, no previous exposure to machine learning is required. However, students are expected to have mathematical maturity at the level of an advanced undergraduate, including being comfortable with linear algebra, multivariate calculus, and (non-measure theoretic) statistics and probability. Assignments include programming in python (and pytorch).

DATA 37784. Representation Learning in Machine Learning. 100 Units.

This course is a seminar on representation learning in machine learning. The core questions in this are: how do machine learning systems recover the structure present in real-world data, how can we expose this recovered structure to human analysts, and how does this help us in real-world applications? In this seminar, we will read and discuss papers from the modern research literature on these subjects. Students should have previous exposure to machine learning and deep learning.
