Arash Vahdat is a principal scientist and research manager, leading the fundamental generative AI research team at NVIDIA Research. Before joining NVIDIA, he was a research scientist at D-Wave Systems where he worked on generative learning and its applications in label-efficient training. Before D-Wave, Arash was a research faculty member at Simon Fraser University (SFU), where he led deep learning-based video analysis research and taught master courses on machine learning for big data. Arash’s current area of research is focused on generative learning with applications in multimodal training (vision+X), representation learning, 3D generation, and AI for science.
- Deep generative learning: diffusion models, variational autoencoders, energy-based models
- Applications: image/graph/text/3D synthesis, controllable generation, label-efficient learning
