Natural-Language-Guided Generator-Agnostic Shortlisting for Protein Binder Design

The study explores using large language models (LLMs) to create ranking policies for shortlisting protein binders after they have been generated by de novo design workflows. By combining precomputed structural‑confidence and interface‑quality proxy scores, the authors demonstrate that iterative LLM policies can modestly improve recall and NDCG metrics over single‑feature baselines. The approach offers an interpretable post‑generation decision layer that helps prioritize binders from large candidate pools.

Be Your Own Teacher: Steering Protein Language Models via Unsupervised Reward Optimization

Protein language models (PLMs) have emerged as powerful tools for controllable biomolecular design, yet their post-training adaptation typically relies on costly wet-lab validation or curated preference datasets. To overcome this supervision bottleneck, we introduce unsupervised reward optimization of PLMs, a comprehensive framework for steerable protein generation without ground-truth labels.

Pairwise Ranking Outperforms Single-Action RL for Offline Explanation Selection: A Practical Lesson

The paper presents a cost‑effective approach for industrial explainable‑recommendation systems by decoupling explanation generation from selection. Explanations are pre‑generated using six prompt styles and two commodity LLMs, then a lightweight CPU‑resident selector (e.g., LambdaRank) chooses the best one at request time, achieving sub‑100 ms latency without GPUs. Experiments on a 2,958‑pair Google Local subset and a 300‑pair MovieLens‑1M split show that pairwise ranking outperforms single‑action RL methods, while KG‑path selectors achieve near‑perfect unique‑output rates, and the overall end‑to‑end build cost is around $15 on commodity hardware.

Janus: An Algorithm-Evaluator Co-Evolution Framework for LLM-Driven Discovery under Expensive Evaluation Budgets

arXiv:2608. 08189v1 Announce Type: new Abstract: LLM-driven program discovery relies on rapid evaluator feedback, but many scientific and engineering tasks require high-fidelity simulations, hardware execution, or physical experiments, making each evaluation expensive.
