    Telling Parkinson's from Essential Tremor Without Symptoms Alone: Diffusion Similarity Networks Plus a Graph Network Reach 87.5% Balanced Accuracy on a Hold-Out Set

    Parkinson's disease and essential tremor look alike early, with misdiagnosis rates of 20% to 30% even at specialized clinics, and the white-matter tracts mapped by conventional diffusion tensor imaging do not capture microstructural change inside gray matter. The study instead builds diffusion similarity networks, linking brain regions by the statistical similarity of their diffusion profiles, then filters connections with iterative permutation sampling recursive feature elimination and classifies with a graph neural network. In five-fold cross-validation on a local cohort of 100 people, the pipeline separated Parkinson's disease from essential tremor with an AUC of 0.94, and on a separate 40-person hold-out set it reached 87.5% balanced accuracy.

    DEP prunes experts per request from prompts in multi-agent systems, beating static pruning and merging baselines most clearly when few experts are kept

    The work proposes Dynamic Expert Pruning (DEP): its analysis shows that in multi-agent systems different tasks and roles recruit different experts while static pruning applies one fixed mask to every request; DEP uses an agent's system and task prompts to produce a per-request expert mask in a single forward pass with no per-configuration calibration, achieving better overall accuracy than static pruning and merging baselines across diverse tasks, roles, model scales, and MoE architectures, generalizing to workflows unseen in training, with the largest margin when few experts are retained.

  3. CEEN assigns one network per time subinterval and trains sequentially, cutting relative error to 1e-3–1e-2 on long-time PDE integrations where PINN fails

    The work proposes causality-enforced evolutional networks (CEEN), which divide the time domain into nonoverlapping subintervals, assign a unique neural network to each subinterval, build the loss from the integral form of the PDE (trapezoidal rule), and train sequentially from the initial time step, achieving higher accuracy than the original PINN on long-time integration of the KdV, Schrödinger, convection, and Allen-Cahn equations while requiring less computational cost and memory, with a parallelization algorithm for further speedup.

    Near-tie restriction lets watermark-fingerprinted models keep text quality at equal detectability

    The authors revisit a watermark-distillation protocol for LLM fingerprinting, show that its utility evaluation understates text-quality degradation in open-ended generation, and propose near-tie restriction, which uses top-1-relative logit gaps to confine the watermark bias to tokens close to the base model's top prediction; across Llama-3.2-3B, Qwen-2.5-3B, Llama-3.1-8B, and Gemma-9B, this improves detection-quality frontiers under sampling, system prompts, quantization, pruning, and fine-tuning, preserves higher text quality across query budgets, and further improves existing schemes when combined with them.

  5. OpenBox aligns 2D vision-foundation instance cues with 3D point clouds to produce more accurate and cheaper 3D box annotations without self-training across three autonomous-driving datasets

    OpenBox introduces a two-stage automatic annotation pipeline: in the first stage it uses a 2D vision foundation model and cross-modal instance alignment to associate instance-level cues from 2D images with the corresponding 3D point clouds; in the second stage it categorizes instances by rigidity and motion state and generates adaptive bounding boxes with class-specific size statistics, thereby producing high-quality 3D bounding box annotations without self-training and improving accuracy and efficiency over baselines on the Waymo Open Dataset, the Lyft Level 5 Perception dataset, and the nuScenes dataset.

  6. Coupling a parameterized PINN with FDM by node assignment yields water-level MAE of about 7.85×10⁻⁵ m and velocity MAE of about 3.21×10⁻³ m/s in a six-tank draining case without retraining

    This study develops the P2F method, a node-assigned hybrid framework that couples a parameterized Node-Assigned physics-informed neural network (NA-PINN) with a finite difference method (FDM) solver: the parameterized NA-PINN takes the water-level difference, initial velocity, and time t as inputs and learns a solution manifold so that a single trained network serves as a data-free surrogate for the momentum conservation equation across all flow paths, while the FDM solver advances the mass conservation equation at each time step to ensure exact discrete mass conservation; verification on a six-tank gravity-driven draining scenario yields a water level mean absolute error of 7.85×10⁻⁵ m and a velocity mean absolute error of 3.21×10⁻³ m/s under the nominal condition with Δt = 1.

    Treating missing modalities as uncertainty: SIUM reaches average Dice of 88.07/87.10/62.52 on BraTS 2018/2020 under missing-modality settings

    The work proposes SIUM, which models each modality subset's task representation as a Gaussian (mean carrying task information, variance measuring uncertainty from missing evidence), aligns subset means toward a full-modality anchor via an uncertainty-aware alignment loss that scales variance with their discrepancy, and adds an uncertainty ordering loss keeping subset variance above its supersets, achieving better segmentation than RFNet, mmFormer, M3AE, and DC-Seg across diverse missing-modality configurations on BraTS 2018 and 2020.

    From Overlooked to Explored: Recovering Item Relations via Mixture of Perspectives for Sequential Recommendation

    Through empirical analysis, this work identifies a "similarity bias" in dot-product self-attention that systematically overlooks heterogeneous item relations carrying causal signal for target prediction, and proposes PRISM, a module that calibrates attention through K Perspective Lenses operating in two complementary views, an Affinity View and a Contrast View, consistently outperforming state-of-the-art baselines on seven real-world benchmarks.
