Mixture of Distributions Matters: Dynamic Sparse Attention for Efficient Video Diffusion Transformers

ICML 2026poster

While Diffusion Transformers (DiTs) have achieved notable progress in video generation, this long-sequence generation task remains constrained by the quadratic complexity inherent to self-attention mechanisms, creating significant barriers to practical deployment. Although sparse attention methods a…

Subspace Optimization for Large Language Models with Convergence Guarantees

ICML 2025poster

Subspace optimization algorithms, such as GaLore (Zhao et al., 2024), have gained attention for pre-training and fine-tuning large language models (LLMs) due to their memory efficiency. However, their convergence guarantees remain unclear, particularly in stochastic settings. In this paper, we revea…

SARAMIS: Simulation Assets for Robotic Assisted and Minimally Invasive Surgery

NeurIPS 2023poster

Minimally-invasive surgery (MIS) and robot-assisted minimally invasive (RAMIS) surgery offer well-documented benefits to patients such as reduced post-operative pain and shorter hospital stays. However, the automation of MIS and RAMIS through the use of AI has been slow due to difficulties in data a…
