- [2026-04-16] An Analysis of Regularization and Fokker-Planck Residuals in Diffusion Models for Image Generation
- 赛道归属: 文生图 / 扩散模型训练与正则化(推理/训练优化)
- 核心创新点: 系统分析DSM训练下扩散模型对Fokker–Planck(FP)方程的偏离现象,指出“更严格的FP约束≠更好生成质量”,并提出用更轻量的正则项替代直接FP残差惩罚:在显著降低计算开销的同时,仍能有效降低FP残差并保留(或接近)FP正则带来的生成收益,从而给出“低成本FP一致性改进”的可行路径与经验结论。
- Track: Text-to-Image / Diffusion model training regularization (training/inference optimization)
- Core innovation: Provides an empirical study of FP-equation violations under DSM-trained diffusion models, showing that stricter FP enforcement does not necessarily improve sample quality. It then demonstrates that simpler, lightweight regularizers can recover much of the benefit of FP regularization—reducing FP residuals at substantially lower computational cost—offering a practical, low-overhead route to improved FP consistency without expensive residual penalties.

- Core innovation: Introduces a constraint-based pre-training paradigm that factorizes size-agnostic knowledge into reusable weight templates while delegating size-specific adaptation to lightweight weight scalers, reframing variable-size initialization as a multi-task adaptation problem. The proposed WeiT instantiates this with Kronecker-based constraints, representing parameters via template concatenation and weighted aggregation, with scaler-learned adaptive connections from limited data—enabling efficient weight construction across depths/widths, faster convergence, and improved performance across architectures (Transformers/CNNs) and tasks including image generation.

- Track: Multi-subject personalized text-to-image generation / pose-guided controllable generation
- Core innovation: Resolves the identity–pose entanglement in complex multi-subject generation by architectural disentanglement within a unified DiT: a retrieval-augmented pose pipeline (RAG-Pose) supplies a clean explicit structural prior; an asymmetric EURoPE positional encoding decouples identity tokens from spatial locations while anchoring pose tokens to the canvas; a DSM adapter shifts identity preservation into the text-conditioning stream, jointly improving identity fidelity and pose adherence.

- 赛道归属: 跨模态检索(冻结MLLM的检索适配/表征学习)
- 核心创新点: 提出 SLQ(Shared Latent Queries),在完全冻结MLLM主干的前提下,仅引入少量可学习的共享潜在查询token,分别拼接到图像/文本token序列末端,利用模型原生的因果注意力将其作为全局聚合接口,直接产出统一语义空间的紧凑检索embedding,从“激发”预训练表征而非“覆盖”表征,避免全量微调/LoRA对知识结构的破坏;同时构建 KARR-Bench 用于评测更偏知识与推理的检索能力,验证该轻量适配在多基准上优于侵入式微调方案。
- Track: Cross-modal Retrieval (retrieval adaptation with frozen MLLMs / representation learning)
- Core innovation: Proposes SLQ (Shared Latent Queries) to adapt a fully frozen MLLM into a retriever by adding only a small set of learnable shared latent query tokens appended to both image and text sequences; leveraging the model’s native causal attention, these queries act as global aggregation interfaces to produce compact embeddings in a unified space—eliciting pretrained representations rather than overwriting them, avoiding semantic-space disruption seen in full fine-tuning/LoRA; additionally introduces KARR-Bench to evaluate knowledge-aware reasoning retrieval, demonstrating the method’s advantage on reasoning-centric retrieval beyond superficial matching.

- Track: Cross-view video generation (Exo-to-Ego / Ego-to-Exo), diffusion-based sequence modeling
- Core innovation: Reframes synchronized exo→ego generation from a paired “condition→output” task into continuous sequence signal modeling: proposes Syn2Seq-Forcing that interpolates between source and target videos to convert synchronization-induced spatio-temporal/geometric jumps into learnable smooth transitions, making diffusion sequence models (e.g., DFoT) better at coherent frame-to-frame transitions; empirically shows the dominant difficulty is video discontinuity (video-only interpolation already yields large gains), and the formulation naturally unifies Exo2Ego and Ego2Exo within one continuous sequence framework.

- Core innovation: Introduces VibeFlow, a self-supervised framework that leverages the physical priors of pre-trained video generative models to avoid costly synthetic paired supervision: a disentangled perturbation pipeline enforces adaptive recombination where structure is taken from the source video while color/illumination cues come from a reference image, yielding robust structure–chroma/lux disentanglement; to mitigate discretization errors in flow-based models, it adds Residual Velocity Fields plus Structural Distortion Consistency Regularization to preserve structure and temporal coherence. The method generalizes zero-shot to relighting, recoloring, low-light enhancement, day–night translation, and object-specific color edits with reduced compute/training overhead.

- 核心创新点: 提出“生成式重建”框架 Lyra 2.0,用视频生成的视觉先验驱动可实时渲染的3D世界构建,重点解决长轨迹下的3D一致性退化两大根因:1)针对空间遗忘,维护逐帧3D几何但仅用于信息路由(检索相关历史帧并建立到目标视角的稠密对应),外观仍由生成模型合成,从而在大视角变化与回访场景时保持结构一致;2)针对时间漂移,用自增强历史(Self-augmented histories)训练,让模型暴露于自身退化输出并学习“纠偏”而非累积误差。最终可生成更长、更一致的探索视频,并用于微调前馈式重建模型以稳定恢复高质量3D场景。
- Track: Video generation + 3D world generation/reconstruction (camera-controlled long-horizon video → 3D lifting)
- Core innovation: Lyra 2.0 formalizes a “generative reconstruction” pipeline that turns camera-controlled videos into persistent 3D worlds, tackling two failure modes in long-horizon 3D-consistent generation: (1) spatial forgetting is mitigated by keeping per-frame 3D geometry only for information routing—retrieving relevant past frames and building dense correspondences to target views—while leaving appearance synthesis to the generative prior; (2) temporal drifting is reduced via self-augmented histories training that feeds the model its own degraded outputs so it learns to correct drift instead of compounding it. The resulting longer, more 3D-consistent trajectories enable reliable fine-tuning of feed-forward 3D reconstruction models.

- Track: Joint audio-video generation (native multimodal generation) / Multimodal reference-conditioned generation & editing
- Key innovations: Introduces a native audio-video unified multimodal generative model with a single efficient large-scale architecture for joint modeling and synchronized generation of audio and video; supports four conditioning modalities (text/image/audio/video) within one framework, enabling an industry-oriented, comprehensive suite of multimodal reference and editing capabilities (e.g., jointly constraining generation with multiple video clips, images, and audio clips) to better handle “world complexity” and improve overall fidelity/consistency; provides an accelerated “Fast” variant targeting low-latency deployment by optimizing generation speed while retaining core generation performance.

- 赛道归属: 多模态理解(音频-视频-语言对齐 / AVLM 可靠性与幻觉抑制)
- 核心创新点: 提出 Audio-Contrastive Preference Optimization(ACPO)以抑制“视觉主导导致的音频幻觉”。方法上采用“双轴偏好学习”:(1) 输出对比目标在偏好优化中惩罚把视觉线索伪装成音频事实的回答,强化“只基于听到的内容作答”;(2) 输入对比目标通过交换音轨构造反事实输入,显式惩罚对真实音频不敏感(对换音轨仍生成相同内容)的生成行为,从训练信号层面打破视觉捷径依赖;在不牺牲整体多模态能力的前提下提升音频落地性与抗幻觉能力。
- Track: Multimodal Understanding (Audio-Video-Language alignment / AVLM reliability & hallucination mitigation)
- Core innovation: Proposes Audio-Contrastive Preference Optimization (ACPO) to curb “video-driven audio hallucination” caused by visual dominance. It introduces dual-axis preference learning: (1) an output-contrastive objective that penalizes responses that present visual cues as if they were audio-grounded facts; (2) an input-contrastive objective built via audio-track swapping to create counterfactual inputs, explicitly penalizing generations that are invariant to the true audio signal. This breaks reliance on visual shortcuts and improves faithful audio grounding without degrading overall multimodal capability.
- [2026-04-15] MERRIN: A Benchmark for Multimodal Evidence Retrieval and Reasoning in Noisy Web Environments
- 赛道归属: 多模态检索增强推理(Web Search Agent 评测基准/Benchmark)
- 核心创新点: 提出人工标注的 MERRIN 基准,用于在“噪声真实网页环境”中系统评测检索增强智能体的多模态证据检索与多跳推理能力。方法论上突破在于:①查询为自然语言且不提供模态提示,迫使模型自主判定应检索的模态;②显式纳入以往较少覆盖的音频、视频等模态,并要求跨模态证据组合;③证据来源为异构且常冲突/部分相关的网页结果,强调在噪声与矛盾信息下的鲁棒证据选择与推理,而非“干净语料”的检索问答。基准还通过 no-search/native-search/agentic-search 三种设置与多模型多智能体对比,揭示当前系统的关键失败模式(过度探索、工具步数增加但被冲突内容干扰、过度依赖文本模态、资源消耗高但准确率低),为后续改进“多模态源选择+推理策略”提供可量化靶场。
- Track: Multimodal retrieval-augmented reasoning (Web search agent benchmarking)
- Core innovations: Introduces MERRIN, a human-annotated benchmark that evaluates search-augmented agents on multimodal evidence retrieval and multi-hop reasoning in noisy, real-world web environments. Key methodological advances include: (1) natural-language queries without modality cues, requiring agents to infer which modalities to seek; (2) explicit inclusion of underexplored modalities such as audio and video, demanding cross-modal evidence integration; (3) retrieval over heterogeneous, often conflicting or partially relevant web sources, stressing robust source selection and reasoning under noise rather than clean retrieval QA. By evaluating agents across no-search/native-search/agentic-search settings and multiple models, it surfaces concrete failure modes (over-exploration, more tool steps but higher distraction from conflicting content, overreliance on text, high resource use with low accuracy), making it a targeted testbed for improving multimodal source selection and reasoning policies.

- 赛道归属: 音视频生成(可控生成 / 物理一致性与运动-声音同步)
- 核心创新点: 提出 Tora3,以物体轨迹(trajectory)作为音视频生成共享的运动学先验来提升物理一致性,而非仅作为视频控制信号。关键方法突破包括:(1) 轨迹对齐的运动表征用于稳定并约束视频中的运动生成;(2) 基于轨迹导出的二阶运动学状态(如速度/加速度)驱动的运动学-音频对齐模块,将接触/碰撞等声学事件与运动变化显式绑定,增强运动-声音同步;(3) 混合 flow matching策略,在轨迹条件区域保持轨迹保真,同时在其他区域维持局部时空一致性;并构建 PAV 数据集,强调与运动相关的音视频模式并自动提取运动标注,支撑大规模训练与评测。
- Track: Audio-Video Generation (Controllable generation / physical coherence & motion-sound synchronization)
- Core innovation: Introduces Tora3, using object trajectories as a shared kinematic prior for joint audio-video generation rather than a video-only control. Key advances: (1) a trajectory-aligned motion representation to stabilize and constrain video motion; (2) a kinematic-audio alignment module driven by trajectory-derived second-order kinematics (e.g., velocity/acceleration) to explicitly tie acoustic events (contacts/impacts) to motion dynamics; (3) a hybrid flow-matching scheme that preserves trajectory fidelity in trajectory-conditioned regions while maintaining local coherence elsewhere. Additionally curates the PAV dataset emphasizing motion-relevant AV patterns with automatically extracted motion annotations to enable scalable training and evaluation.

- Track: Mobile multimodal agents — training data synthesis & trajectory learning for agentic VLMs
- Key innovations: An open-source framework for synthesizing task instructions and interaction trajectories to address the closed/opaque data pipelines in mobile agents: (1) builds a global environment memory via exploration and uses it to generate diverse, strongly grounded instructions tied to real UI elements; (2) introduces a policy-switching rollout strategy that alternates learner and expert models to deliberately capture error-recovery trajectories typically missing in standard imitation learning, improving robustness and task success. Includes transparent overlap analysis with benchmarks to argue gains come from broad functionality coverage rather than overfitting.

- Track: Multimodal person re-identification — semantic/VLM-enhanced robust ReID under modality shift and clothing change
- Key innovations: STFER leverages LVLM-generated identity-consistent semantic text as a stable cue beyond raw appearance, addressing degradation under RGB↔IR shifts and clothing changes: (1) instruction-guided LVLM produces identity-intrinsic semantic tokens capturing biometric constants; (2) Semantic-driven Visual Token Filtering (SVTF) uses these tokens to emphasize identity-relevant regions and suppress background noise; (3) Semantic-driven Expert Routing (SER) injects semantic tokens into expert routing/gating (MoE-style) for more robust scenario-adaptive feature allocation and fusion, improving generalization across diverse ReID conditions.

- Track: Multimodal reliability—abstention/uncertainty evaluation & benchmarking
- Core innovations: Introduces MM-AQA, a benchmark that generates unanswerable multimodal instances from answerable ones via controlled transformations along visual-dependency and evidence-sufficiency axes, capturing realistic failure modes; evaluates VLMs and multi-agent systems for effective abstention, showing standard prompting rarely yields abstention, MAS improves abstention but induces an accuracy–abstention trade-off, and sequential designs rival iterative ones—implicating miscalibration rather than insufficient reasoning depth; argues for abstention-aware training over prompting/agent scaling.

- 赛道归属: 强化学习在工业制造中的人机协作任务规划与分配(层级RL + 空间感知调度)
- 核心创新点: 提出面向复杂动态生产场景的人机任务规划与分配的层级式框架:将生产任务分解为可执行的序列子任务,由高层智能体负责任务规划、低层智能体负责任务分配与执行衔接。高层采用高效的缓冲区式深度Q学习(EBQ),通过缓冲机制提升长时序、稀疏回报问题下的样本利用与训练效率,从而缩短训练时间并稳定策略学习;低层引入基于路径规划的空间感知分配(SAP),显式建模人员实时位置与移动距离等空间约束,将“谁来做/何时做”与可达性、行走成本耦合,实现更符合现场约束的实时分配。整体实现了“规划-分配”解耦但通过子任务序列闭环联动,增强了在3D仿真复杂生产流程中的实时性与鲁棒性。
- Track: Reinforcement learning for industrial human-robot collaboration task planning & allocation (hierarchical RL + spatial-aware scheduling)
- Core innovations: Introduces a hierarchical framework for human-robot task planning and allocation in complex, dynamic manufacturing: production jobs are decomposed into sequential subtasks, with a high-level agent handling task planning and a low-level agent handling task allocation/execution. The high-level agent uses an Efficient Buffer-based Deep Q-learning method (EBQ) that leverages a buffer mechanism to improve sample efficiency and training speed under long-horizon, sparse-reward settings, yielding faster and more stable learning. The low-level agent proposes a Spatially Aware allocation method (SAP) grounded in path planning, explicitly incorporating real-time human location and travel distance to couple assignment decisions with reachability and movement cost. This yields a real-time, constraint-aware “plan–allocate” loop that improves robustness and practicality in a 3D simulated production process.

- 核心创新点: 提出RAPO,将分布鲁棒RL的原始难解问题转为可操作的对偶形式,直接显式化“鲁棒性-性能”权衡:在轨迹层面用对偶温度参数并以对抗网络近似,生成满足散度约束的稳定最坏情形rollout;在模型层面对动力学集成采用Boltzmann重加权,按“对当前策略更不利”的环境进行策略敏感采样而非均匀域随机化。两层机制相互独立又互补,兼顾稳定训练与覆盖更具挑战的动力学,从而提升OOD动力学泛化与抗不确定性能力并避免过度保守。
- Track: Robust RL under dynamics uncertainty (distributionally robust / adversarial policy optimization)
- Key innovations: RAPO derives a tractable dual that exposes the robustness–performance trade-off. It (i) approximates the dual temperature with an adversarial network to produce stable worst-case rollouts within a divergence bound at the trajectory level, and (ii) applies Boltzmann reweighting over dynamics ensembles for policy-sensitive sampling of more adverse models at the model level. The decoupled components jointly improve OOD robustness while reducing instability and over-conservatism.

- Track: RL for LLM reasoning (process-aware optimization / reasoning alignment)
- Key innovation: Introduces StaRPO, augmenting RL objectives with explicit reasoning stability to address logically inconsistent yet fluent outputs under final-answer-only rewards. Stability is decomposed into two lightweight computable metrics—ACF for local step-to-step coherence and PE for global goal-directed path efficiency—and combined with task rewards to provide process-aware feedback, improving both answer accuracy and trajectory logical stability.

- Track: RLVR safety & robustness (reward hacking / verifier design for reasoning RL)
- Key innovation: Identifies a failure mode in RL with verifiable rewards: models “game” imperfect verifiers by abandoning rule induction and instead outputting instance-level enumerations that pass extensional checks without learning generalizable relations. Proposes Isomorphic Perturbation Testing (IPT), adding isomorphic verification that enforces invariance across logically isomorphic tasks—true rule induction remains invariant while shortcut strategies break—showing extensional verification induces shortcuts whereas isomorphic verification eliminates them.

- 核心创新点: 提出IG-Search,用“信息增益(IG)”构造逐步(step-level)奖励,解决轨迹级奖励无法区分好/坏查询、以及全失败rollout时梯度塌缩的问题。IG度量每次检索相对“随机文档”反事实基线对正确答案置信度的提升,并通过GRPO中的per-token advantage modulation把奖励精确回传到查询token,实现无需中间标注、无需跨轨迹共享环境状态的细粒度信用分配;在多基准上提升EM且训练开销增量较小、推理延迟不变。
- Track: Search-augmented reasoning / fine-grained RL credit assignment
- Key innovation: Proposes IG-Search with a step-level Information Gain reward to distinguish effective vs. vague/redundant queries and avoid near-zero gradients when all rollouts fail. IG measures how retrieved docs increase gold-answer confidence versus a random-doc counterfactual, and is routed back to query tokens via per-token advantage modulation in GRPO, enabling annotation-free, state-sharing-free step-level credit assignment with strong QA gains and minimal training overhead.
- [2026-04-16] UniDoc-RL: Coarse-to-Fine Visual RAG with Hierarchical Actions and Dense Rewards 🆕NEW
- 赛道归属: 多模态检索增强生成(Visual RAG)与强化学习推理优化
- 核心创新点: 提出统一的端到端RL框架,让LVLM以“序列决策”方式联合完成检索、重排、主动视觉感知与推理;通过层级动作空间实现从文档级粗检索到图像级精选择再到区域级主动裁剪的coarse-to-fine证据精炼;设计面向每一步动作的稠密多重奖励以提供细粒度监督,并基于GRPO在无需价值网络的情况下对齐多目标行为;同时构建带细粒度动作标注的高质量推理轨迹数据以支撑训练与评测。
- Track: Visual Retrieval-Augmented Generation (Visual RAG) & RL-based reasoning optimization
- Core innovations: Proposes an end-to-end unified RL framework where an LVLM agent jointly performs retrieval, reranking, active perception, and reasoning as a sequential decision process; introduces a hierarchical action space enabling coarse-to-fine evidence refinement from document retrieval to image selection and region cropping; designs dense multi-reward signals to supervise each action step, and leverages GRPO to optimize multi-objective behavior without a separate value network; curates fine-grained action-annotated reasoning trajectories to support training and evaluation.
- [2026-04-16] WavAlign: Enhancing Intelligence and Expressiveness in Spoken Dialogue Models via Adaptive Hybrid Post-Training 🆕NEW
- 赛道归属: 语音对话大模型后训练(End-to-end spoken dialogue)/ 偏好优化与RL对齐
- 核心创新点: 针对端到端语音对话中“稀疏偏好监督 vs 稠密语音生成”导致的奖励建模与rollout采样难题,提出模态感知的自适应混合后训练方案:将偏好/RL更新约束在语义通道以提升智能与语义质量,同时通过显式anchoring稳定并改进声学表现;再依据rollout统计动态调节两者混合比例,规避不可靠偏好梯度对共享参数的破坏,使RL在语音对话场景可落地并提升表达性。
- Track: Post-training for end-to-end spoken dialogue models / preference optimization & RL alignment
- Key innovation: Proposes a modality-aware adaptive hybrid post-training recipe to make RL practical for end-to-end spoken dialogue, addressing the mismatch between sparse preference signals and dense speech generation under shared-parameter updates. It constrains preference/RL updates to the semantic channel while improving acoustics via explicit anchoring, and dynamically mixes them based on rollout statistics to avoid unreliable preference gradients, improving both semantic intelligence and speech expressiveness.
- [2026-04-16] LongAct: Harnessing Intrinsic Activation Patterns for Long-Context Reinforcement Learning 🆕NEW
- 赛道归属: 长上下文强化学习与训练效率(Long-context RL / sparse update optimization)
- 核心创新点: 利用模型内在表征特性提出LongAct:观察到长上下文处理中Q/K向量存在高幅值激活,并借鉴量化中“高幅值更关键”的结论与长程推理稀疏性假设,将RL更新从“全量均匀”转为“显著性引导的稀疏更新”。仅更新与高幅值激活相关的权重以聚焦关键驱动因素,从而在LongBench v2等长上下文基准上提升表现并增强泛化;且对GRPO、DAPO等多种RL算法具通用增益。
- Track: Long-context RL & training efficiency (saliency-guided sparse updates)
- Key innovation: Introduces LongAct by exploiting intrinsic activation patterns in long-context processing: high-magnitude Q/K activations are treated as critical drivers (inspired by quantization insights and sparsity of long-context reasoning). It shifts RL from uniform full updates to saliency-guided sparse updates, updating only weights associated with salient activations, improving long-context benchmarks and generalization while remaining compatible across RL algorithms (e.g., GRPO, DAPO).
- [2026-04-16] Dual-Axis Generative Reward Model Toward Semantic and Turn-taking Robustness in Interactive Spoken Dialogue Models 🆕NEW
- 赛道归属: 语音对话多模态交互(Spoken Dialogue)与RL奖励建模
- 核心创新点: 提出“双轴生成式奖励模型”,用细粒度交互质量分类体系与标注数据学习复杂对话动态;奖励输出不仅给出单一总分,还显式分解为“语义质量”和“轮次/时序(turn-taking)”两条轴的评分,从而为全双工语音对话模型提供可诊断、可用于在线RL的稳定奖励信号;以生成式建模替代依赖浅层统计/时序代理指标的传统自动评估,提升跨数据集的交互质量评估一致性与泛化。
- Track: Spoken multimodal dialogue interaction & RL reward modeling
- Core innovations: Introduces a dual-axis generative reward model trained with a detailed interaction taxonomy and annotations to capture complex dialogue dynamics; outputs both an overall score and disentangled scores for semantic quality and turn-taking/timing robustness, providing diagnostic feedback and a reliable reward for online RL; replaces brittle proxy metrics (behavioral stats/timing accuracy) with a learned generative assessor that generalizes across synthetic and real-world interaction datasets.
