  1. Beyond Top-k Skill Retrieval: Diversity-Aware Skill Routing for LLM Agents

    Beyond Top‑k Skill Retrieval: Diversity‑Aware Skill Routing (DSR) applies a Determinantal Point Process with a query‑residual diversity kernel to rerank skill candidates, balancing relevance and redundancy. On the SkillRouter benchmark it raises recall and full‑coverage, especially for multi‑skill queries, showing that skill routing benefits from set‑selection rather than independent ranking.

  2. Online Learning with LLM Experts from Limited Feedback

    The paper models prompt routing to multiple LLM experts as a bandit problem with limited feedback and proposes algorithms that achieve sublinear regret in both full‑information and bandit settings. Experiments demonstrate that the methods learn effective routing strategies across diverse LLMs using only a small feedback budget.

  3. DataFlex-RL: An Evaluation Platform for RLVR Data Policies

    The paper introduces DataFlex‑RL, a platform to benchmark how different data‑selection policies affect reinforcement‑learning‑with‑verifiable‑rewards training. Across extensive experiments on Qwen2.5‑7B and Llama‑3.1‑8B, uniform sampling is the only method that consistently improves performance, and no alternative policy yields a statistically significant gain.

  4. Grounded Skill Synthesis from Code at Scale for Agentic Intelligence

    Code2Skill is an automated pipeline that mines popular GitHub repositories to extract verifiable, implementation‑anchored procedural “skills”. It builds a bank of ~1 M skill records (atomic ops, workflows, patterns) with provenance metadata, verifies each via blind reconstruction, and shows that augmenting LLM‑based agents with these skills yields an average 11.7% performance lift across 72 proto…

  5. Building and Evaluating Fixed-Voice Thai TTS from Synthetic Speech

    Researchers train a compact 82 M‑parameter Thai fixed‑voice TTS model using synthetic speech generated by a large voice‑cloning teacher, requiring only a 15‑second real reference. The student achieves 68.2% keyword accuracy and 91.4% pause precision, outperforming its teacher on pause placement and enabling on‑device inference.

  6. How Far Can Synthetic Data Take Thai OCR?

    The paper dissects which aspects of synthetic Thai OCR data (typeface diversity, 2‑D layout, real handwriting glyphs) actually help transfer to real documents. Using those insights they train Wayu-Paxa-OCR-Zero without any real OCR labels and achieve character error rates comparable to or better than supervised baselines.

  7. Learning Sparse Decision Trees via Transformer Variational Auto-Encoders

    The paper presents TREVIS, a method that encodes decision trees into a continuous latent space using a Tree Transformer VAE, allowing gradient-based optimization of both accuracy and structural sparsity. Experiments claim TREVIS matches the predictive performance of near-optimal algorithms while producing sparser trees.

  8. PLC-DPO: Posterior Label Correction in Noisy and Ambiguous Preference Optimization

    PLC‑DPO extends Direct Preference Optimization by using the policy‑reference margin to route each training pair into clean, flipped, or tie categories, actively correcting noisy or ambiguous labels. Across extensive benchmarks it improves mean win‑rate from 55.5 % to 60.5 % and stays stable under injected noise and tie stress tests.
