FedSPM: Routing-Enabled Federated Learning under Dual Heterogeneity via Semiparametric Mixture

Zijian Wang, Pengfei Li, Guangyu Yang, Qiong Zhang

Routing-prediction federated learning has emerged as a new paradigm that reframes inter-client heterogeneity as a resource for system-level intelligence: at inference time, the server routes each external query to the best-matched client for prediction. Existing approaches, howev…

PosterHarness: Turning Scientific Poster Generation into an Auditable Instruction-Following Benchmark

Tianyi Yang, Dawei Fu, Youpeng Wu, Zixun Kou, Linrui Chen, Ruobing Jiang, et al.

Text-rich image models can now design poster-scale layouts, but we lack ways to measure whether they honor scientific communication contracts: legible labels, prescribed aspect ratios, and -- above all -- abstaining from fabricated scientific figures. We present POSTERHARNESS, an…

LASER: A Corrective Lens for LVLMs via Visual Attention Preservation and Sink Suppression

Bowen Yuan, Zijian Wang, Yadan Luo, Shijie Wang, Zi Huang

Large vision-language models (LVLMs) exhibit strong reasoning ability but suffer from visual forgetting during long-horizon decoding, where attention progressively drifts away from visual evidence. Existing methods largely treat this issue as a late-stage attention decay problem…
