The study explores how Sparse AutoEncoders (SAEs) represent part-of-speech (PoS) categories in language models, finding that PoS distinctions are recoverable from SAE activations but not directly mapped to individual latents. Instead, they are supported by compact groups of sparse features that vary across tags and show stability across data.
The chart will appear after repeat observations. The current metric comes from the source.

This could help in understanding how language models encode grammatical structures, potentially improving interpretability and feature engineering.
The paper introduces Taste-Bench, a benchmark for evaluating an agent's 'taste' in making long-horizon decisions. It measures the ability to choose the better path in decision forks without knowing future outcomes, revealing that current models perform poorly and that taste can be improved through distillation.

This approach preserves document structure, reduces token costs, and improves chunking efficiency compared to traditional methods.
4 days agoDaily PapersHappyWorld-Bench is a comprehensive benchmark for evaluating the reliability of generated worlds under interaction, exploring their consistency and responsiveness. It includes three tracks—video, spatial, and embodied world models—with 1,138 video prompts, 300 spatial scenes, and 254 embodied test cases. The benchmark uses human A/B comparisons and automated metrics to assess behavioral correctness and model performance across 14 video, 9 spatial, and 8 embodied systems.

The system, called ScriptMoE, outperforms existing methods on multilingual text recognition tasks by leveraging a large synthetic dataset and a lightweight architecture that shares a visual encoder while using script-specific experts for decoding.
4 days agoDaily PapersOmniEdu is an open family of foundation models designed for K-12 education, focusing on problem solving, curriculum understanding, diagnostic reasoning, and instructional support. The models are trained on a diverse dataset of educational resources and evaluated on multiple benchmarks, showing strong performance in educational tasks.
6 days agoDaily PapersThe paper introduces Spatial-Interactor, a framework for training vision-language models (VLMs) to model physical-world state transitions through interaction. It uses a three-level curriculum and a dataset of simulated and real interaction trajectories to improve spatial reasoning in dynamic environments.
