MPBench: A Comprehensive Multimodal Reasoning Benchmark for Process Errors Identification

ACL 2025finding

Reasoning is an essential capacity for large language models (LLMs) to address complex tasks, whereas the identification of process errors is vital for improving this ability. Recently, process-level reward models (PRMs) were proposed to provide step-wise rewards that facilitate reinforcement learni…

InfoBatch: Lossless Training Speed Up by Unbiased Dynamic Data Pruning

ICLR 2024oral

Data pruning aims to obtain lossless performances with less overall cost. A common approach is to filter out samples that make less contribution to the training. This could lead to gradient expectation bias compared to the original data. To solve this problem, we propose InfoBatch, a novel framework…
