Similar Models Learn Differently: Final-Window Pretraining Shapes Post-Training Beyond SFT

Cen Lu, Yung-Chen Tang, Andrea Cavallaro

Developers judge a model checkpoint by how it behaves. After supervised fine-tuning (SFT), two checkpoints that perform about the same across relevant benchmarks are treated as int…

Sparse Neuron Ablation Triggers Catastrophic Collapse of the Language Core in Large Vision-Language Models

Cen Lu, Yung-Chen Tang, Andrea Cavallaro

Large Vision-Language Models (LVLMs) have shown impressive multimodal understanding capabilities, yet the structures that sustain their functionality remain poorly understood from…

CarBoN: Calibrated Best-of-N Sampling Improves Test-time Reasoning

Yung-Chen Tang, Pin-Yu Chen, Andrea Cavallaro

Allocating more computation during inference time (test-time scaling) improves language model performance, especially for reasoning tasks. However, popular methods like Best-of-…
