Beyond Answer Accuracy: Diagnosing Perception Failures in Multimodal Mathematical Reasoning

Multimodal Large Language Models (MLLMs) have shown strong performance on mathematical reasoning tasks that combine textual and visual information. However, final-answer accuracy offers limited insight into whether errors arise from incorrect perception, modality-dependent information extraction, or downstream reasonin...

Stratified Sparse Attention: Reducing the Sparse-to-Dense Gap at Extreme Sparsity

Large Language Model inference over long contexts is increasingly bottlenecked by the cost of attending to a growing Key-Value (KV) cache. Sparse attention reduces this cost by accessing only a fraction of the cache, but existing methods face a trade-off between deterministic retrieval, which captures high-scoring toke...
