LatentGym: A Testbed For Cross-Task Experiential Learning With Controllable Latent Structure

Daksh Mittal, Tommaso Castellani, Thomson Yen +7

We envision continually learning agentic systems that become more useful over time: as they encounter sequences of related tasks, they should infer the hidden structure shared acro…

Data Mixture Optimization: A Multi-fidelity Multi-scale Bayesian Framework

Thomson Yen, Andrew Wei Tung Siah, Haozhe Chen +3

Careful curation of data sources can significantly improve the performance of LLM pre-training, but predominant approaches rely heavily on intuition or costly trial-and-error, maki…
