Dataset distillation and dataset pruning are two prominent techniques for compressing datasets to improve computational storage efficiency. Despite their overlapping objectives, these approaches rarely compared directly. Even within each field, the evaluation protocols inconsistent across various methods, which complicates fair comparisons hinders reproducibility. Considering limitations, we introduce in this paper a benchmark that equitably evaluates methodologies both literatures. Notably,...

Chain-of-Thought significantly enhances a model's reasoning capability, but it also comes with considerable increase in inference costs due to long chains. With the observation that path can be easily compressed under easy tasks struggle on hard tasks, we explore feasibility of elastically controlling length paths only one model, thereby reducing overhead models dynamically based task difficulty. We introduce new tuning and strategy named CoT-Valve, designed allow generate chains varying...
