QUESTION — How can an agentic graphic design system continually adapt and evolve procedural memory from user traffic without updating model weights?
Five rounds over 1,406 real user briefs and 1,869 automatically graded trajectories, with no weight updates and no human labels, grow the bank from 76 documentation-derived skills to 139 and raise GenEval2 execution success on Claude-Sonnet-4 from 72.7% to 99.3% (+11.99 points in generation quality).
QUESTION — How can query routing and agent policies co-evolve within a continual learning framework for Mixture-of-Agents?
This work introduces CERA-MoA (Co-Evolving Router with continually learning Agents for Mixture-of-Agents), an iterative reinforcement learning framework designed to co-evolve query routing and independent agent policies. It employs a predictive familiarity estimator leveraging mid-layer hidden states to evaluate semantic competence among agents without full rollout overhead. Using these familiarity scores, a cumulative-threshold adaptive routing mechanism dynamically activates a tailored minimal agent subset to balance performance and efficiency, while proactively allocating targeted training samples to foster agent capability differentiation.

QUESTION — How can vision-language models achieve panoptic grounded captioning through mask proposal selection?
This work studies panoptic grounded captioning, which requires a vision-language model to describe foreground objects and background regions while grounding referring phrases with pixel-level masks. The authors introduce PanoCaps, a human-annotated benchmark built from panoptic segmentation datasets, along with a phrase-mask matching protocol and a generalized Panoptic Quality (gPQ) metric. They propose PANORAMA, a VLM that conditions a pretrained segmenter on contextualized phrase representations to select corresponding candidate masks. Joint training with caption generation enables the production of precise entity-level segmentations and detailed, mask-consistent captions.
QUESTION — How can representation evolution in Transformers be decomposed into parallel and perpendicular components to improve editing and compression?
