Papers from Wednesday, 16 September 2026

23 papers

Agentic Systems & Scientific Workflows

  • ScienceBuddy introduces a recursive-⁠in-⁠recursive self-⁠improvement paradigm for interactive scientific agents, coupling harness evolution with model reinforcement learning to support continual learning from researcher feedback and execution evidence, released as a research product with case studies across four scientific task families [1].
  • Agentic societies require a social harness beyond personal harnesses to prevent failures, detect invalid messages, and enable post-⁠facto investigations, as current messaging primitives leave vulnerabilities to faulty or malicious agents [2].
  • SEAA integrates a behavior-⁠inertia HMM, reflexive metacognition, and social-⁠contrastive self-⁠modeling to enable endogenous self-⁠evolution and a self–other boundary in LLM agents [3].
  • FlashVector extends agentic optimization from single GPU kernels to the full model-⁠serving stack (framework graph, server, feature processing) for recommender systems, delivering cross-⁠layer performance gains [4].

LLM Reasoning, Reliability & Evaluation

  • Chain-⁠of-⁠Self-⁠Questioning (CoSQ) is a prompt-⁠only framework that conditions answer commitment on an explicit assessment of required information, reducing wrong-⁠commitment rate by 32.1% relative on TruthfulQA while increasing answered accuracy and coverage across 11 model families [5].
  • Fuse is a multi-⁠agent simulation framework for verifiable social reasoning, validating simulation faithfulness via a 24k-⁠annotation human study and revealing that user mediation compounds social reasoning difficulty for LLMs [6].
  • SWE-⁠bench leaderboard saturation: Top entries share most successes/failures, with no adjacent top-⁠30 pairs separable by exact paired McNemar tests; scaffold–model interactions exceed score spreads, challenging fine-⁠grained rankings [7].
  • LLMs develop linearly decodable belief-⁠state geometry in-⁠context when prompted with HMM data, with interventions on the identified subspace preserving prediction quality, confirming functional relevance of these representations [8].

Efficiency, Serving & Compression

  • JustFit enables 200K-⁠token LLM serving on a 24 GiB laptop via KVExec compression, PhaseSwap residency, and StateTrans state-⁠preserving transitions, achieving 6.93× context expansion and 19.11 tokens/s on Qwen3.8-⁠27B MXFP4 [9].
  • LACE introduces layer-⁠wise compression for dynamic frame-⁠rate audio codecs, applying independent compression at each quantization layer with union alignment and boundary anchors to maintain duration consistency for TTS [10].
  • Persistent Recurrent Memory between transformer layers (via cross-⁠attention + GRU) reduces LM evaluation loss by 28.5% and generalization gap by 54% with only 3.7% added parameters, with gains tied to memory topology rather than auxiliary losses [11].
  • ECHO (speculative decoding) uses early-⁠layer bonus logits for rapid multi-⁠step draft-⁠tree exploration and final-⁠layer logits for path correction, improving acceptance rates and wall-⁠clock speedups across benchmarks [12].

Uncertainty, Calibration & Safety

  • Episode-⁠Normalized Conformal Prediction (ENCP) rescales nonconformity scores by residual confidence and calibrates per episode, providing step-⁠wise coverage guarantees for VLN despite dependent, variable-⁠length trajectories across policies and scores [13].
  • Coupled Calibration and Learning (CCL) mitigates teacher bias in LLM distillation under covariate shift without target-⁠domain rewards by iteratively calibrating the teacher on source feedback and training the student on target data, with polynomial-⁠rate convergence guarantees [14].
  • Conformal Policy Learning (CPL) offers distribution-⁠free safety guarantees for high-⁠stakes decision-⁠making by thresholding conformal p-⁠values to control the probability of harmful treatment assignments [15].
  • CoTS and E-⁠CoTS apply temperature scaling to calibrate test-⁠time prompt tuning, preserving accuracy while mitigating miscalibration; weak–strong ensembling further boosts performance [16].

Vision, Language & Multimodal

  • PhysStream enables physics-⁠grounded, fine-⁠grained motion control for image-⁠to-⁠video generation via structured scene memory (positional/object tracking maps) and sparse velocity-⁠increment signals, trained with bidirectional then causal autoregressive stages [17].
  • Tables Decoded: DELTA reconstructs table structure and content into OTSL format, while TARQA answers table VQA from structured text, achieving SOTA TSR scores and competitive TabVQA performance without visual encoders [18].
  • ECHO (turn-⁠taking benchmark) is a paired diagnostic for Chinese full-⁠duplex dialogue, requiring context-⁠sensitive Yield/Keep decisions on identical overlap transcripts with contrasting histories, exposing a strong Yield bias in most systems [19].
  • Det-⁠LIME adapts LIME for object detection with per-⁠detection weighting, box-⁠aligned proximity kernels, and IoU-⁠based instance matching, producing high-⁠resolution, biologically relevant explanations for marine mammal detection [20].

Domain-⁠Specific Applications

  • Quantum-⁠Harbor + QIQCBench introduce a virtual lab and 49 expert tasks to evaluate verified autonomy in quantum engineering, covering calibration, error correction, compilation, sensing, and networking [21].
  • Memorisation bias in medical AI: Models’ predictions on a patient’s future data can shift significantly if the model saw that patient’s historical data during training, persisting across modalities, architectures, and even decades, with asymmetric effects on diagnostic accuracy [22].
  • ASURRE benchmark shows LLM-⁠assisted survey responses are detectable when naive but approach human-⁠like behavior with persona-⁠grounded agents, with behavioral traces enabling training-⁠free aggregation detectors [23].
