TQTS-Bench: A Multi-Syntax Benchmark for Text-to-Query over Time-Series Databases

TQTS-BENCH is introduced, a multi-syntax benchmark for evaluating text-to-query capabilities over TSDBs, and error analysis reveals that this performance gap mainly stems from the heterogeneous query syntaxes across different TSDBs, misinterpretation of time-specific intents, and incorrect schema linking.

Self-Indexing Attention for Compression-Compatible Sparse Long-Context LLM Inference

Self-Indexing Attention is proposed, a training-free framework built on a shared transform-domain sign-magnitude representation that provides a reusable token-level index for grouped prefill selection and decode retrieval, while the same representation remains compatible with external KV-cache compression without separ...

Semantically Compatible Knowledge Distillation for Cross-Domain Object Detection with Vision Foundation Models

The Semantic Localization-Enhanced Teacher (SLE-T), a semantically compatible knowledge-distillation framework built around a lightweight SLE Adapter for DINOv2, achieves state-of-the-art performance and ablation studies confirm the importance of teacher-student semantic compatibility.

Learning-State-Aware Dynamic Generative Data Augmentation on Small-Scale Datasets

Learning-state-aware dynamic generative data augmentation (LSADA) is proposed, which introduces a decoupled data augmentation and diffusion fusion strategy that applies strength-controlled transformations to class-relevant regions and generates diverse class-irrelevant regions, progressively fusing them to improve imag...
