Chen, Ji and Xu propose the DiGCA phase classifier, generating Lifshitz-Petrich phase diagrams about two orders of magnitude faster with over 98% classification accuracy

The authors propose a Derivative-informed Graph Convolutional Autoencoder (DiGCA) phase classifier that feeds both the Lifshitz-Petrich model solutions and their derivatives (the nonlocal term G(φ)) into a graph convolutional autoencoder for dimensionality reduction, then classifies with a fully connected neural network, generating phase diagrams over the parameter domain [−0.01,0.05]×[0,1] with over 98% classification accuracy, roughly two orders of magnitude faster than MCMS-RBM, and remaining stable under up to 10% additive white noise.

DeepFisFis processes 5 ms audio segments in about 2.5 ms, detecting mouse ultrasonic vocalizations in real time and triggering closed-loop stimulation

The work introduces DeepFisFis, a waveform-based neural network that classifies consecutive 5 ms audio segments to detect mouse ultrasonic vocalizations (USVs) while they are being produced, processing each segment in approximately 2.5 ms and thus faster than the incoming audio stream; in a deployed closed-loop system, detections triggered an external stimulus, demonstrating online control of ongoing vocal behaviour, and event-triggered acquisition preserved more than 99% of vocalization time while retaining only approximately 22% of the continuous recording.

Anthropic says 950 Claude agents flagged a repeat pattern around a known enzyme in 21 hours; biologists say that is not a discovery

Anthropic announced that 950 Claude agents in its molecular biology lab flagged, within 21 hours, a repeating pattern surrounding a known enzyme in a large library of DNA sequences, saying the pattern had not been catalogued before, while some biologists argue that finding gene clusters and repeats is often the easy part and that the real discovery lies in figuring out what the system actually does, and a University of Copenhagen researcher says his team had already found the pattern.

Duplex-MPE tests 2,000 multi-party dialogue scenarios and finds that talking more is not answering better, with MiniCPM-o 4.5 leading three of four capabilities

The authors introduce Duplex-MPE, a benchmark of 2,000 paired scenarios with three or four human speakers plus an assistant named Aria, contrasting explicit naming with implicit addressing, and evaluate five open-weight full-duplex speech systems on continuous audio without transcripts, speaker labels or turn boundaries using four scores—fresh response initiation, conditional answer accuracy, silence preservation and answering-window yield—finding that MiniCPM-o 4.5 leads on three scored capabilities while frequent speech from other systems often coexists with inaccurate answers or failures to remain silent.

Nereus adapts RL post-training parallelism on the fly: 27.7% lower average step latency on a real-data trace and up to 7.27x OpenRLHF throughput for 8B PPO

Nereus is a cost-aware runtime for reinforcement-learning post-training of large language models that represents each model-stage replica as an Elastic Model Unit and orchestrates Split, Merge, Extend, and Destroy primitives through a global transition graph, adapting the DP/TP/PP execution plan online under a payback rule; on a trace built from real data, online TP/PP adaptation cuts average step latency by 27.7% versus the initial fixed TP/PP layout, six transitions in a 1,000-step run scaling to 1,024 GPUs consume 0.079% of total run time, and end-to-end 8B PPO throughput improves by 2.14-7.27x over OpenRLHF and 1.10-1.47x over Verl.

Writing robot tasks as code: HexaAnything lifts RoboCasa365 Composite-Unseen success from 34.3% to 38.3% and turns Harness traces into a stronger HexaModel

The work proposes Physical Coding, representing physical world state (Code as World) and execution procedure (Code as Policy) as executable programs, and builds the physical coding agent HexaAnything, which treats VLA/WAM policies as callable action tools while a Harness owns state bookkeeping, verification, and recovery; on RoboCasa365 with XR-1 as the action model it raises Composite-Unseen success from 34.3% to 38.3% and overall success from 56.6% to 61.1%, a HexaModel v0.1 fine-tuned on Harness-collected traces beats its base model on every split in the same Harness, PhyBench simulated physics experiments are completed with mean relative errors below 5%, and on a dual-arm AgileX robot five of seven tabletop tasks succeed in all three trials.

Freezing debate prevented 29 collapses but lost 108 corrections across 6,925 MMLU-Pro debates

The work introduces an auditable protocol for homogeneous three-agent LLM debate that decomposes final accuracy into preserved, collapse, correction, and unrepaired transitions with collapse onset and signed intervention utility, identifies 253 collapses across 6,925 MMLU-Pro debates, and shows via replay that a leave-one-model-out probe-gated freeze prevents 29 collapses while losing 108 corrections under equal weights, so collapse prevention alone can recommend the wrong policy.

VisionHOPE turns visual backbones into self-modifying learning systems, reaching competitive results on ImageNet-1K, COCO, and ADE20K

The work introduces VisionHOPE, which formulates a visual backbone as a self-modifying learning system in which five coupled memories for content, key, value, learning rate, and retention co-evolve along each scan, and pairs this with a stability-matched step-size control (a soft cap on self-referential injection plus a spectral clamp on the retained memory transition) that is proved to yield non-expansive memory dynamics, achieving competitive results on ImageNet-1K, COCO, and ADE20K.

Peking University-led team distills coding ability from one-word answers: a Qwen2.5-1.5B student beats an exact nuisance-matched control by 5.34 points on HumanEval+

The work introduces Active Taskless Distillation (ATD), which uses a public ancestor model to select unrelated prompts on which it is nearly indifferent between two ordinary words, has a privately post-trained teacher return a single word per prompt, and trains a same-ancestor student only on those prompt-word pairs; in the primary Qwen2.5-1.5B coding experiment, 5,664 single-word responses yield a 5.34 percentage-point gain on HumanEval+ over an exact nuisance-matched control, with positive mean gains also observed in scientific knowledge, commonsense reasoning, and reading comprehension across additional model generations, sizes, and families.

NVAlign backpropagates a frozen NV-ASR reward through the flow-matching sampler, lifting human-rated tag-following on three continuous AR-FM TTS systems by up to 39.8% to 54.0%

NVAlign is a direct-gradient post-training framework for non-verbal control in continuous autoregressive flow-matching TTS: it first supervised-fine-tunes TTS models and a Qwen3-Omni-30B-based NV-ASR model on NVV-annotated speech, then freezes the NV-ASR as a reward model and uses a two-step gradient surrogate to backpropagate target-tag probabilities through the flow-matching sampler, jointly updating the autoregressive backbone and acoustic flow head under fidelity penalties and reference-velocity regularization; on NVV-SuperBench and blinded listening evaluations it improves tag-following accuracy over SFT and Flow-GRPO baselines on VoxCPM2, dots.tts, and an English production system.
