While Experience Replay—the practice of storing rollouts and reusing them multiple times during training—is a foundational technique in general RL, it remains largely unexplored in LLM post-training due to the prevailing belief that fresh, on-policy data is essential for high performance. In this wo…
Optimizing the misclassification risk is in general NP-hard. Tractable solvers can be obtained by considering a surrogate regression problem. While convergence to the regression function is typically sublinear, the corresponding classification error can decay much faster. Fast and super fast rates (…
Annotating datasets is one of the main costs in nowadays supervised learning. The goal of weak supervision is to enable models to learn using only forms of labelling which are cheaper to collect, as partial labelling. This is a type of incomplete annotation where, for each datapoint, supervision is…
