MIBURI: Towards Expressive Interactive Gesture Synthesis

Intermediate
M. Hamza Mughal, Rishabh Dabral et al.Mar 3arXiv

MIBURI is a system that makes a talking digital character move its body and face expressively in real time while it speaks.

DreamWorld: Unified World Modeling in Video Generation

Intermediate
Boming Tan, Xiangdong Zhang et al.Feb 28arXiv

DreamWorld is a new way to make videos that not only look real but also follow common-sense rules about motion, space, and meaning.

SenCache: Accelerating Diffusion Model Inference via Sensitivity-Aware Caching

Intermediate
Yasaman Haghighi, Alexandre AlahiFeb 27arXiv

SenCache speeds up video diffusion models by reusing past answers only when the model is predicted to change very little.

Accelerating Diffusion via Hybrid Data-Pipeline Parallelism Based on Conditional Guidance Scheduling

Intermediate
Euisoo Jung, Byunghyun Kim et al.Feb 25arXiv

Diffusion models make great images but are slow because they fix noise step by step many times.

#diffusion inference#multi-GPU acceleration#data parallelism

SARAH: Spatially Aware Real-time Agentic Humans

Intermediate
Evonne Ng, Siwei Zhang et al.Feb 20arXiv

SARAH is a real-time system that makes virtual characters move their whole bodies naturally during a conversation while knowing where the user is.

MolHIT: Advancing Molecular-Graph Generation with Hierarchical Discrete Diffusion Models

Intermediate
Hojung Jung, Rodrigo Hormazabal et al.Feb 19arXiv

MolHIT is a new AI that builds molecules as graphs, moving from broad chemical groups to exact atoms step by step.

World Action Models are Zero-shot Policies

Intermediate
Seonghyeon Ye, Yunhao Ge et al.Feb 17arXiv

DreamZero is a robot brain that learns actions by predicting short videos of the future and the matching moves at the same time.

DreamID-Omni: Unified Framework for Controllable Human-Centric Audio-Video Generation

Intermediate
Xu Guo, Fulong Ye et al.Feb 12arXiv

DreamID-Omni is one model that can create, edit, and animate human-centered videos with matching voices, all in sync.

PixelGen: Pixel Diffusion Beats Latent Diffusion with Perceptual Loss

Intermediate
Zehong Ma, Ruihan Xu et al.Feb 2arXiv

PixelGen is a new image generator that works directly with pixels and uses what-looks-good-to-people guidance (perceptual loss) to improve quality.

Self-Refining Video Sampling

Intermediate
Sangwon Jang, Taekyung Ki et al.Jan 26arXiv

This paper shows how a video generator can improve its own videos during sampling, without extra training or outside checkers.

#video generation#flow matching#denoising autoencoder

Alterbute: Editing Intrinsic Attributes of Objects in Images

Intermediate
Tal Reiss, Daniel Winter et al.Jan 15arXiv

Alterbute is a diffusion-based method that changes an object's intrinsic attributes (color, texture, material, shape) in a photo while keeping the object's identity and the scene intact.

#intrinsic attribute editing#visual named entities#identity preservation

Future Optical Flow Prediction Improves Robot Control & Video Generation

Intermediate
Kanchana Ranasinghe, Honglu Zhou et al.Jan 15arXiv

FOFPred is a new AI that reads one or two images plus a short instruction like “move the bottle left to right,” and then predicts how every pixel will move in the next moments.
