MeshOctave: Vertex Split-and-Rewire Cascades for Native Mesh Generation

Generating compact, artist-style meshes with explicit topology typically relies on autoregressive models which incur prohibitive sequential per-token costs, or continuous flow models that depend on heuristic connectivity decoders. Next-scale generation paradigms offer a compelling alternative by enabling parallel intra...

MemeBench: What LVLMs Miss When Interpreting Culture-Dependent Memes

KAR, an entity-guided retrieval baseline built on CultureBase is introduced and MemeBench is introduced, a diagnostic benchmark of 1,253 Chinese and English memes with human-written references and quality-controlled VIKR annotations, centered on anime, comics, games, and adjacent online subcultures, to reveal whether a...

Influence-Directed Distillation: Solving the Diversity Bottleneck in Sampled-Token On-Policy Distillation

Experiments show Influence-Directed Adaptive On-Policy Distillation (IDA-OPD), rather than relying on costly full-vocabulary Forward-KL objectives, preserves entropy-expanding updates while replacing entropy-contracting ones with divergence-adaptive advantage shrinkage, using only the teacher's sampled-token log-probab...

MemeMind: Reference-Guided Trace Construction for Offline Context Optimization

This work introduces MemeMind, which uses an offline reference answer to recover missing experience in Anime, Comic, and Game meme interpretation and shows that constructing successful tool use for failed groups provides the largest component gain and produces more effective evidence acquisition at inference time.
