Seeing What’s Wrong: A Trajectory-Guided Approach to Caption Error Detection

ICLR 2026poster

Error detection is critical for enhancing multimodal dataset reliability and downstream model performance. Existing error filters, while increasingly powerful, typically rely on a single similarity score per image–caption pair. This is limiting: captions with subtle errors (e.g., mislabeled objects,…

3BASiL: An Algorithmic Framework for Sparse plus Low-Rank Compression of LLMs

NeurIPS 2025poster

Sparse plus Low-Rank $(\mathbf{S} + \mathbf{L}\mathbf{R})$ decomposition of Large Language Models (LLMs) has emerged as a promising direction in $\textit{model compression}$, aiming to decompose pre-trained model weights into a sum of sparse and low-rank matrices $\mathbf{W} \approx \mathbf{S} + \ma…

TSENOR: Highly-Efficient Algorithm for Finding Transposable N:M Sparse Masks

NeurIPS 2025poster

Network pruning reduces computational requirements of large neural networks, with N:M sparsity—retaining only N out of every M consecutive weights—offering a compelling balance between compressed model quality and hardware acceleration. However, N:M sparsity only accelerates forward-pass computation…
