Imbalanced Gradients in RL Post-Training of Multi-Task LLMs

Runzhe Wu, Ankur Samanta, Ayush Jain +7

Multi-task post-training of large language models (LLMs) is typically performed by mixing datasets from different tasks and optimizing them jointly. This approach implicitly assume…

Simple Optimizers for Convex Aligned Multi-Objective Optimization

Ben Kretzu, Karen Ullrich, Yonathan Efroni

It is widely recognized in modern machine learning practice that access to a diverse set of tasks can enhance performance across those tasks. This observation suggests that, unlike…

Projection-Free Online Convex Optimization with Time-Varying Constraints

Dan Garber, Ben Kretzu

We consider the setting of online convex optimization with adversarial time-varying constraints in which actions must be feasible w.r.t. a fixed constraint set, and are also requir…

Projection-free Online Exp-concave Optimization

Dan Garber, Ben Kretzu

We consider the setting of online convex optimization (OCO) with \textit{exp-concave} losses. The best regret bound known for this setting is , where is the dimens…

New Projection-free Algorithms for Online Convex Optimization with Adaptive Regret Guarantees

Dan Garber, Ben Kretzu

We present new efficient \textit{projection-free} algorithms for online convex optimization (OCO), where by projection-free we refer to algorithms that avoid computing orthogonal p…

Improved Regret Bounds for Projection-free Bandit Convex Optimization

Dan Garber, Ben Kretzu

We revisit the challenge of designing online algorithms for the bandit convex optimization problem (BCO) which are also scalable to high dimensional problems. Hence, we consider al…
