ENCORE - Engaging New Controversial Original Rigorous Entertaining

AI for Quants – Accelerated, explainable AI/ML in capital markets

Seminar by Jochen Papenbrock

13th July 2021

Dr. Jochen Papenbrock returns to the LQG to discuss the implications and benefits of work completed with a team at Munich Re Markets on robust accelerated portfolio construction and market data generators which was published in the spring edition of the Journal of Financial Data Science – accessible here

Business, regulatory and performance requirements demand robust, explainable, trustworthy, sustainable, efficient, transparent, and larger AI/ML models. Jochen will illuminate the current era of model building, referencing algorithmic developments including risk management techniques.

Jochen will also highlight how to access freely available open source software so you can harness potentially massive improvements in processing times while retaining IT cost control and critical business flexibility – in short how to access “your own” super-computer – or more accurately your own accelerated computing platform – without having to learn a totally new language and without paying the earth for the privilege!
