Joint Webinar with Inquire UK

Prize Winners

Professor Lin Cong will present on how to optimize investment objectives by using reinforcement learning. 

We will be kicking off 2021 with our next webinar organized jointly with Inquire UK. Professor Lin William Cong, Cornell University, will present his research paper, “Single-Step Portfolio Construction through Reinforcement Learning and Economically Interpretable AI.“ 

Date: 13 January 2021

Time: 16:00 CET

Presentation overview:

Professor Cong and his co-authors propose direct optimization of investors' objectives via reinforcement learning. This is an alternative to the widely-adopted two-step portfolio-management paradigm which entails estimating distributions of asset returns. Building on recent breakthroughs in AI, they develop neural-network-based multi-sequence models which are tailored to various distinguishing features of economic and financial data.

The resulting AlphaPortfolio yields stellar, out-of-sample performances (e.g., Sharpe ratio above two) that are robust under various economic and trading restrictions. Moreover, they use polynomial-feature-sensitivity and textual-factor analyses to project the model onto linear regression; natural language spaces uncover key market signals that drive investment performance.

Overall, the authors highlight the utility of reinforcement deep learning in social sciences, especially finance, and provide novel "economic distillation'' procedures for interpreting AI and big data models.
