This course is intended to confront M.sc. and Ph.D. students in economics, finance, and related fields with recent tools developed in applied mathematics, machine learning, computational science, and the computational economics literature to solve and estimate state-of-the-art models.
The lectures will be centered around sparse grids, adaptive sparse grids, two types of machine learning methods (Gaussian Processes and Deep Neural Networks), and will be showcased in the context of application in climate change economics, macroeconomics, and finance. The lectures will be interactive, in a workshop-like style, that is, a mix of theory and actively playing with code examples (delivered in Python and deployed on a cloud computing infrastructure).
- Graduate-level mathematics (see, e.g., "Mathematics for Machine Learning". The book is freely downloadable here: https://mml-book.github.io).
- Solid coding skills in Python (see, e.g., https://python-programming.quantecon.org/intro.html, Sections 1 - 7).
- Some working knowledge of recursive methods (see, e.g., Stokey et al. , Ljungqvist and Sargent ).
Participants who take the course for credits are expected to propose a small project where they apply some of the methods learned to an application (e.g., apply deep learning to a data set, solve a dynamic model, etc.). The deliverable that will be graded is a short write-up (4-6 pages maximum), the data set (if any), and the code on which the presented results in the report were based. The participants will have four weeks' time after the course is finished to complete the task.
