    No sentence cuts, no waiting: CRESiST interleaves reads and writes so unsegmented streaming translation trails oracle segmentation by only 1–2 COMET points

    CRESiST replaces prefix-incremental generation in LLM-based simultaneous speech translation with an interleaved sequence of speech chunks and target tokens, so the KV cache is reused across the whole stream and no voice activity detection is needed to cut sentences. An RNN-T Actor samples read-or-write trajectories, a Qwen2.5-omni-7B Critic with Router and Refiner scores them on semantic consistency and latency, and reverse distillation feeds the decisions back to the Actor. On MuST-C and ACL 60/60, unsegmented streaming lands only 1–2 COMET points below the oracle-segmented setting.

    Visual verifiers stop answering only true or false: OmniVerifier-C1 splits prompts into sub-questions and lifts ViVerBench overall to 0.684

    Visual verifiers have long returned only a true-or-false verdict, which cannot separate partially correct outputs from worse ones. OmniVerifier-C1 decomposes a complex prompt or environmental rule into fine-grained sub-questions, judges each one binarily, and turns the satisfied fraction into a continuous score, while a decoupled reinforcement-learning scheme optimizes sub-question judgments and global alignment scoring together. On ViVerBench, the Qwen3-VL-8B version trained with graded supervised fine-tuning plus graded reinforcement learning reaches an overall score of 0.684, above 0.671 for binary reinforcement learning alone.

    Masked diffusion models lock answers too early: HiLo-RD distills large-window trajectories, lifting GSM8K accuracy by 9.4 points

    Masked diffusion language models can fix answer fragments before the supporting reasoning is resolved when the response window is small, and those fragments then become context for later predictions. HiLo-RD uses the same model's large-window trajectory as a frozen teacher and aligns its hidden representations to cropped small-window views at committed positions. At the same small inference budget, GSM8K accuracy rises from 68.84% to 78.24% while mean readable length falls from 362.8 to 271.3 tokens, and the gains extend to code generation without code-domain training.

    Streaming video-to-audio closes the alignment gap: LiveFoley needs only 0.08 s of frontend look-ahead and runs at 156 ms end-to-end

    Real-time video-to-audio has been held back by two bottlenecks: visual frontends shrink their receptive fields to cut look-ahead, and causal diffusion backends denoise each patch in isolation, so both alignment and audio quality trail offline models. LiveFoley uses a trailing sliding window to turn off-the-shelf non-causal segment-level encoders into streaming modules without retraining, cutting frontend look-ahead to 0.08 s, and widens the backend denoising window toward history. On the VGGSound test set, LiveFoley-48k reaches a DeSync of 0.48, on par with offline MMAudio-L at 0.47, with 156 ms end-to-end latency on a single A800 GPU.

    Liver CT diagnosis switches to composing findings: diseases unseen in training are detected and localized

    Liver CT diagnosis models usually predict disease labels directly from images, so they only recognize diseases seen in training. DbC splits diagnosis into two steps: it learns a set of radiological findings as dense maps over the scan, then defines each disease by the findings its guidelines require and composes the diagnosis map with a fixed, parameter-free soft-minimum operator. On multi-phase liver CT, for six diseases never seen in training, DbC localized lesions significantly better than every comparator, including models that align images with disease names, and kept its advantage on rare diseases from another institution and on a public external cohort.

    Video attention often confuses different scene elements: GAD distills geometry-model attention, lifting Wan2.2 5B cross-frame matching by at least 30%

    Video diffusion models lose scene geometry when the camera moves or objects move, because cross-frame attention often spreads its response over several regions instead of locking onto the same scene element. GAD extracts correspondence targets from the attention of a frozen geometry foundation model, VGGT-, on clean videos, and routes supervision by noise timestep to the layer where scene structure is forming, training video attention with pairwise and trackwise objectives. On 15-second long-range generation with RealEstate10K and DL3DV-10K, adding GAD to Wan2.2 5B raises cross-frame matching hit rate by at least 30% relative on both datasets, with no extra inference modules or computation.

    UGR generates Taobao's organic, ad and cross-business candidates in one pass, lifting online transaction volume 3.29%

    Ranking in Taobao's Guess You Like service no longer generates a list over a truncated single-business candidate set and then hands it to cross-business blending. UGR generates one list over roughly a thousand organic, ad and other-business candidates per request, models historical ad exposure separately during training, and adds current ad value at serving. In an online A/B test on Guess You Like, UGR raised Core IPV by 1.76%, Transaction Volume by 3.29% and GMV by 2.10% over the production baseline.

    Fixing an LLM's weak spot is not enough: judging its knowledge state first lifts two benchmarks by 18.41 points on average

    Knowledge improvement for large language models is moving from predefined incorporation pipelines to evaluation-guided updating, yet locating a weak spot does not say which intervention fits. Recursive Knowledge Improvement (RKI) organizes knowledge into graph-structured units and, each round, localizes weaknesses, estimates the model's operational knowledge state from diagnostic evidence and intervention history, selects an intervention, and re-evaluates the updated model. On HotpotEval and SafeInternalEval, RKI outperforms existing knowledge incorporation methods by 18.41 points on average, and analyses indicate knowledge states add guidance beyond weakness localization and can change across updates while the observed weakness persists.

    Agents iterate their own data recipes: math and code selection strategies gain up to 13.34% under fixed training

    Agents use experimental feedback to revise data-engineering strategies, and across four tasks—math and code data selection, math reward design, and math curriculum learning—the selected strategies gain up to 13.34% absolute over generic baselines on AIME25 Pass@32 under fixed training conditions.

    Multi-turn agent distillation stops feeding student reasoning to the teacher: a 4B student beats its 32B teacher on ALFWorld Seen at 43.39%

    Multi-turn agent distillation now grounds teacher supervision in the interaction state, keeping only executed actions and observations, and the Qwen3-4B student surpasses its 32B teacher on ALFWorld Seen at 43.39%.
