Oct 18, 2023

If you are relying on influencers or academics with a marketing budget to show you the ‘latest’ techniques in quantitative finance, you are missing out on 99% of all quantitative finance research.

To get information directly from thousands of academic-practitioners at blog.ml-quant.com we are plugged in directly to the source, e.g., ArXiv, GitHub, and SSRN.

You will most likely be able to expense this newsletter depending on your industry and role. Thanks to reader support from DE Shaw, Arrowstreet, AQR, MAN, and Blackrock, I will soon be adding a modern react website.

Its amazing how little the following papers are publicly discussed, I will just add them here for those who want to click quickly.

Few-Shot Learning Patterns in Financial Time-Series for Trend-Following Strategies
Leveraging Large Language Model for Automatic Evolving of Industrial Data-Centric R&D Cycle
Deep Structural Model: A Fusion of Machine Learning and Theory
