DataCupid: Stable Matching Repair for Training Data Acquisition with Delayed Feedback

Read the original on arXiv Machine Learning →

The paper introduces RLR, a stable matching repair method that reuses valid observations while respecting matching capacity and handling delayed, out‑of‑order evaluations. RLR combines sound outcome certificates with batched matching schedules to manage unequal sample deficits, achieving a sharp issue‑round bound and separate delay and evidence‑lifetime bounds. The authors also present RLR‑P, a variant that monitors issue‑order prefixes without altering the sampling plan, and demonstrate through simulations that it reduces mean capped update‑certification time compared to a width‑based baseline, albeit with higher oracle CPU cost.

Fix, Not Just Resample: Bounded Compiler-Guided Repair in Lean 4

The paper presents a bounded, online step-level repair module for Lean 4 that uses compiler error messages to fix rejected tactics instead of discarding them. By sampling up to $K$ candidate tactics and allowing at most $R$ repairs per step, the method improves solve rates over a sampling-only baseline, achieving up to a 32% relative gain and solving 82 additional theorems on a 1,990-theorem subset of the LeanDojo benchmark. The approach trades extra runtime for reachable proofs, with most benefit coming from early repair attempts and shallow tactic failures, and it successfully replicates on the Lean Workbook benchmark, nearly doubling its solve rate without regressions.

BulkPR-Bench: Benchmarking Queue-Level Governance of Interacting Pull Requests

arXiv:2608. 02685v1 Announce Type: cross Abstract: Coding-agent benchmarks increasingly cover long-horizon, end-to-end, and interactive development, but typically retain one requested outcome or a fixed change sequence.

Beyond Endpoint Scores: Time- and Capacity-Conditioned Evaluation of Continual Knowledge Updating

The paper argues that evaluating continual knowledge‑updating methods solely at a final checkpoint and a single adapter rank can be misleading. By fixing a periodic hierarchy and comparing it to cumulative replay on a 24‑month Wikidata stream, the authors show that the apparent best method changes depending on the evaluation month, replay LoRA rank, and query formulation. They recommend reporting performance trajectories and capacity sweeps, and only declaring a robust winner when the ranking remains stable across the evaluation region.
