Towards Nonlinear Disentanglement in Natural Data with Temporal Sparse Coding

Explore the concept of nonlinear disentanglement in natural data through temporal sparse coding in this 52-minute talk by Yash Sharma at the Tübingen seminar series of the Autonomous Vision Group. Delve into unsupervised representation learning techniques for disentangling underlying factors of variation in naturalistic videos. Examine the SlowVAE model, which leverages temporally sparse distributions to achieve disentanglement without assumptions on the number of changing factors. Learn about the proof of identifiability and the model's performance on benchmark datasets. Discover new video datasets with natural dynamics, Natural Sprites and KITTI Masks, introduced as benchmarks for disentanglement research. Gain insights into time contrastive learning, permutation contrastive learning, and the Slow Variational Autoencoder. Explore results on various datasets and consider open questions in the field of disentanglement in machine learning.
