The Inverse Heat Mean Flow is introduced, a general-purpose solver that is compatible with a wide range of model backbones that directly learns an average velocity field through an inverse heat formul ation, thereby simplifying trajectory learning and enabling adaptive topological alignment.
Unified multimodal retrieval aims to build a single system capable of handling diverse modalities, tasks, and domains. While recent approaches leveraging multimodal large language models (MLLMs) have shown promise, they face a fundamental dilemma between capacity and interference: scaling dense models improves semantic understanding but incurs prohibitive inference costs, while training a single shared parameter space on heterogeneous data leads to severe gradient conflicts and negative transfer. In this work, we propose Retrv-MoE, a unified retrieval architecture built upon sparse Mixture-of-Experts (MoE). Unlike dense retrievers that activate all parameters for every input, Retrv-MoE employs learnable routers to dynamically select a small subset of experts for each token. We theoretically and empirically demonstrate that this conditional computation mechanism provides a structural remedy to optimization interference by decoupling the learning trajectories of conflicting tasks and domains into specialized expert subspaces. Extensive evaluations on the M-BEIR benchmark reveal that Retrv-MoE achieves a superior trade-off between efficiency and performance. It significantly outperforms efficiency-oriented baselines and matches the retrieval quality of 7B-parameter dense models while utilizing about 3 billion active parameters. Furthermore, our analysis confirms that the router exhibits emergent specialization, effectively mitigating negative transfer and enabling robust zero-shot generalization to unseen datasets and video retrieval tasks.

Multi-exposure fusion (MEF) expands the luminance range beyond what a single exposure can capture. Combining images taken at different exposure levels requires handling geometric differences while naturally merging their complementary brightness information. It often demands generative completion where details are missing. Diffusion-based generative methods address these challenges, however, they are computationally expensive and struggle to preserve fine structures in saturated regions. We propose LIIFusion, a coarse-to-fine framework that balances fusion quality and efficiency in generative MEF. The coarse stage performs low resolution generative fusion, enhanced by an adaptive exposure correction that recovers structure lost in saturated over-exposed areas. The fine stage adapts a local implicit image function into a multi-exposure fusion function: conditioned on the HR OE/UE sources and the coarse output, it queries arbitrary target coordinates and fuses source evidence regardless of the HR input resolution. LIIFusion achieves up to 3.5$\times$ speed-up over existing generative methods while maintaining or improving structural fidelity and perceptual quality. We believe this framework provides an effective pathway toward making generative MEF more practical in real-world applications.
