SafeStart: Mitigating the Overlooked Safety Cost of Active Expert Reduction in MoE LLM Serving

This paper reveals that expert-reduction methods for MoE LLM serving, which speed up inference by running fewer experts per token, can weaken refusal of harmful requests. The authors introduce SafeStart, which runs all experts for the prompt and first eight generated tokens, then reduces experts afterward, preserving most speedup while restoring safety. In vLLM on an RTX A6000, SafeStart keeps at least 85% of the offline decode speedup at batch sizes 8 and 32 and reduces harmful compliance increases to near baseline levels across three models.

Why it matters: Provides a concrete, recent finding that expert reduction in MoE serving has safety costs and offers a practical mitigation, valuable for AI serving systems and safety research.

Text-Only Training for Zero-Shot Video Temporal Localization

This paper explores training a text-only LLM on synthetic textual video descriptions to perform temporal grounding, receiving video only at inference. The authors generate a 134K-example corpus, adapt Qwen3-8B with LoRA on text embeddings, and propose Nearest Entity Replacement (NER) to bridge the modality gap. NER improves zero-shot performance on Charades-STA and QV-Highlights, but a significant gap remains.

CARM: Conformal Adaptive Risk Masking for Reliable Scientific Super-Resolution

CARM is a statistical framework that adapts conformal risk control to temporal distribution shifts in Earth-observation super-resolution. It aggregates threshold proposals from experts with different update rates using an asymmetric surrogate loss, enabling rapid adaptation while maintaining stability. Theoretical guarantees show time-averaged mask-conditioned risk converges to at most alpha at O(1/T) rate. On South China Sea chlorophyll-a data, CARM reduces empirical violation rate from 43.49% to 9.38% at alpha=0.10, with consistent improvements on ERA5 and OSTIA datasets.

Why it matters: Provides a novel, theoretically grounded method for reliable AI in scientific super-resolution, with strong empirical results across multiple datasets.

Reasoning-Aware Cross-Modal Association Unlearning in Multimodal Large Reasoning Models

This paper introduces cross-modal association unlearning for multimodal large reasoning models (MLRMs), targeting the removal of specific visual-to-knowledge associations rather than whole samples or concepts. The proposed VKCR method localizes edits to a compact parameter subspace and counterfactually rebinds reasoning behavior to suppress target leakage while preserving non-sensitive knowledge. New benchmarks CLEAR-R and MLLMU-R evaluate leakage, hallucination, and utility, showing VKCR reduces image-conditioned target leakage across tasks.

Why it matters: Addresses a novel privacy problem in multimodal reasoning models with a parameter-efficient method and benchmarks, offering practical value for AI safety and unlearning research.

A Definition of Catastrophic Performance

This paper introduces a formal definition of catastrophic performance to distinguish suboptimal AI outcomes from truly catastrophic ones. The definition relies on two reference values: baseline value (no agent deployed) and orthogonal value (a trajectory unrelated to human preferences). Catastrophic performance is characterized as an agent undoing benefits from past human activity, enabling rigorous analysis of AI misalignment risk.

Rubric Curriculum RL Improves RLVR in Non-Verifiable Domains

The paper introduces Rubric Curriculum RL (RcRL), a method that exploits the generation-verification gap in domains without ground-truth rewards by combining pairwise preferences over rollouts with a curriculum over rubric criteria. This creates a more discriminative and non-stationary training signal, avoiding the plateau seen in baselines. RcRL achieves a 70.5% human win rate on creative writing and improves HealthBench performance by 14.6% (full set) and 25.4% (consensus subset), outperforming all training baselines.

Why it matters: This presents a concrete, novel training method with measurable gains in open-ended domains, addressing a key limitation of RLVR.

PRAT outperforms or matches strong baselines on fifteen node-classification benchmarks, with ablations confirming the importance of the indefinite metric.

Why it matters: This work offers a novel theoretical insight and a practical method that improves GNN performance on heterophilic graphs, a challenging and active research area.

NextGAN: Towards Simple and Scalable GAN Training for Image and Video Generation

NEXTGAN trains a scalar critic by regressing its input gradient onto displacements between independently paired reference and generated features at interpolated locations in frozen representation spaces. The authors state that, for a fixed generator, this regression is equivalent to an adversarial objective with a gradient-energy penalty, while the generator keeps the standard potential-based GAN update. The method adapts pre-trained image and video generators with up to 14B parameters without auxiliary losses, online teacher scores, or trajectories. On ImageNet 256x256 it reports one-step FIDs of 2.87 with pixel-space JiT-B and 1.54 with latent-space DiT-XL/1 (1.36 for its adversarial form), and a single Wan2.1-1.3B model supports one-, two- and four-step text-to-video sampling, scoring 83.13 VBench total at two steps.

Why it matters: It offers a simpler adversarial training recipe for few-step image and video generation, backed by one-step FID and VBench comparisons, which is useful for researchers and practitioners building fast generative models.

OccSplat Targets Occluded Geometry in Driving-Scene Gaussian Splatting

Researchers propose OccSplat, a feed-forward 3D Gaussian Splatting framework for reconstructing driving scenes from surround-view images. Rather than inpainting missing pixels in rendered views, the method identifies regions lacking Gaussian support via Gaussian Occlusion Mapping and generates new primitives through Gaussian Occlusion Completion. These primitives are merged into the original representation, keeping feed-forward inference without per-scene optimization. Experiments on nuScenes show improvements over compared methods, with the largest gains reported in occluded regions.

MonoLaDN: Language-Guided DeNoising for Monocular 3D Object Detection

MonoLaDN is a training framework that transfers geometric reasoning from a frozen vision-language model into a monocular 3D detector. It encodes the VLM's structured reasoning about occlusion, depth, dimension, and angle into queries, perturbs them with noise, and trains the detector to reconstruct the clean reasoning. The deployed detector remains purely vision-based, adding no inference latency or parameters. Experiments on KITTI 3D and nuScenes report consistent improvements over state-of-the-art detectors and good generalization to new domains.

The Split Protocol Decides the Result: Re-Evaluating Encrypted Traffic Classification

This arXiv paper shows that encrypted traffic classifiers can score macro-F1 0.992 under a standard evaluation protocol but only 0.567 when flows from one packet capture are kept on one side of the split. Across five split protocols on backbone QUIC traffic, server-disjoint splitting costs 0.192 macro-F1, while random, temporal and client-disjoint splits are statistically indistinguishable from session-disjoint splitting. The authors propose single-identifier probes as a pre-training diagnostic for identifying the relevant split axis, and report that several pre-registered architectural claims fail under the corrected evaluation.
