A Pinch of SFT, A Dash of RL: When Reinforcement Learning Helps Long-Horizon Advertising Agents

The paper investigates how to balance supervised fine‑tuning (SFT) and reinforcement learning (RL) for long‑horizon advertising agents that must retrieve, reason, and execute code on distributed business data. By classifying training trajectories into Imitation, Lift, and Discovery regimes, the authors develop a diagnostic that predicts which training path to follow, and then apply a targeted SFT‑then‑RL strategy. Across 18 feature‑specific experiments on GPT‑OSS 120B, this approach yields positive gains on most advertiser skills, reduces leakage, and achieves higher mean improvements with 43% less RL compute.

EvoRank: LLM-Guided Evolution of Multi-Objective Learning-to-Rank Pipelines

EvoRank is an open autonomous ranking engineer that uses an LLM-guided evolutionary loop to automatically design complete Learning-to-Rank pipelines—including features, models, losses, and ensembles—for multi-objective e-commerce search. On the Expedia ICDM 2013 dataset, EvoRank converged within 50 iterations on interpretable pipelines that outperform an Optuna-tuned LambdaMART on 60k held-out queries and rank in the top 6 % of the original competition. The authors also introduce a headroom gate that predicts whether the evolutionary loop will be worthwhile before any LLM computation, and they release the system, auditing tools, and a catalog of failure modes to help teams apply the method to their own ranking stacks.

Can Coding Agents Reproduce Official Statistics? Metadata, Retry Budget and the Limits of Execution Feedback in a Controlled Eurostat Benchmark

The paper investigates whether large language models can reliably reproduce official Eurostat statistics by generating executable code. It evaluates a coding agent across four experimental conditions—task only, task plus metadata, metadata with a repair loop using execution feedback, and metadata with a retry budget but no diagnostics—using 30 natural‑language tasks spanning seven domains and datasets. Results show that success depends on semantic validation against frozen specifications, a fully specified output contract, and a retry budget, rather than on execution diagnostics alone.
