Finding Signal in the Noise: Machine Learning and the Markets with In Young Cho

In Young Cho, Ron Minsky

Inyoung Cho details her transition from biology to Jane Street, where she now leads machine learning initiatives that leverage thousands of GPUs and terabytes of daily market data to navigate the anti-inductive nature of financial signals. Her presentation contrasts the firm's direct client trading model, which mitigates market impact through human interaction, with modern research pipelines that prioritize data discipline over model interpretability to prevent overfitting in high-frequency environments. Looking forward, Cho outlines how Jane Street is applying deep learning and foundation models to extract signals from multimodal data while refining internal tools through structured training that balances rapid exploration with robust production systems.
