Structured Thoughts For Improved Reasoning And Context Pruning

Zain Sarwar, Supriyo Chakraborty, Berkcan Kapusuzoglu +5

Large language models (LLMs) excel at generating long chains of thought, but long reasoning traces are often verbose and memory-inefficient. In this work, we introduce Structured T…

Critique-Guided Distillation for Robust Reasoning via Refinement

Berkcan Kapusuzoglu, Supriyo Chakraborty, Zain Sarwar +2

Supervised fine-tuning with expert demonstrations often produces models that imitate outputs without internalizing the reasoning processes needed for robust generalization. While c…

Continual Pre-training of MoEs: How robust is your router?

Benjamin Thérien, Charles-Étienne Joseph, Zain Sarwar +7

Sparsely-activated Mixture of Experts (MoE) transformers are promising architectures for foundation models. Compared to dense transformers that require the same amount of floating-…

Dense Backpropagation Improves Training for Sparse Mixture-of-Experts

Ashwinee Panda, Vatsal Baherwani, Zain Sarwar +4

Mixture of Experts (MoE) pretraining is more scalable than dense Transformer pretraining, because MoEs learn to route inputs to a sparse set of their feedforward parameters. Howeve…

MYCROFT: Towards Effective and Efficient External Data Augmentation

Zain Sarwar, Van Tran, Arjun Nitin Bhagoji +3

Machine learning (ML) models often require large amounts of data to perform well. When the available data is limited, model trainers may need to acquire more data from external sou…
