Lou Schlessinger

Machine Learning Engineer & Researcher

About

I'm Louis ("Lou") Schlessinger, a machine learning engineer and researcher interested in mathematical reasoning, spatial cognition, and neuro-inspired AI. I currently work on projects exploring how intelligent systems learn, reason, and build internal representations of the world.

A few things about me: I led the team that placed runner-up for the 2023 Vesuvius Challenge Grand Prize, presented work on automated model search at the NeurIPS Meta-Learning workshop, and have built large-scale multimodal ML systems in production. I hold B.S. and M.S. degrees in computer science from Washington University in St. Louis.
