An important aspect of the expressiveness of a programming language, concerns what kinds of things it can manipulate as data. This course introduces programming in a dependently typed functional language. In such a language both functions and types are ordinary data. This enables features such as higher-order and generic functions, as well as data whose type depends on the value of other data. One benefit of working in this setting is that properties of programs can be both expressed and proved within the language itself, providing much stronger guarantees of correctness than is possible using testing.

Machine learning (ML) is the study of computer programs that can autonomously improve performance by exposure to additional data, and it is increasingly central to financial research and the finance industry. Both established firms and “FinTech” startups use ML to determine creditworthiness, allocate investment resources, and predict the future of company, sector, or national equities. These efforts raise interesting technical and ethical questions. Course content is divided between advanced technical topics like deep neural networks, deep reinforcement learning, and multi-agent simulation, and financial topics like the efficient markets hypothesis, capital assets pricing model, and mean-variance portfolio optimization. Emphasis is on empirical machine learning applied to financial topics, careful analysis of the results, and the need for responsible approaches to ML. Programming-heavy, project-heavy course. Strong CS background is needed. No prior finance knowledge is expected.
