Disentangled Action Recognition with Knowledge Bases

NAACL 2022long

Action in video usually involves the interaction of human with objects. Action labels are typically composed of various combinations of verbs and nouns, but we may not have training data for all possible combinations. In this paper, we aim to improve the generalization ability of the compositional a…

Quantitative Understanding of VAE as a Non-linearly Scaled Isometric Embedding

ICML 2021spotlight

Variational autoencoder (VAE) estimates the posterior parameters (mean and variance) of latent variables corresponding to each input data. While it is used for many tasks, the transparency of the model is still an underlying issue. This paper provides a quantitative understanding of VAE property thr…

Rate-distortion optimization guided autoencoder for isometric embedding in Euclidean latent space

ICML 2020poster

To analyze high-dimensional and complex data in the real world, deep generative models, such as variational autoencoder (VAE) embed data in a low-dimensional space (latent space) and learn a probabilistic model in the latent space. However, they struggle to accurately reproduce the probability distr…
