Covariate-informed Representation Learning to Prevent Posterior Collapse of iVAE

AISTATS 2023poster

The recently proposed identifiable variational autoencoder (iVAE) framework provides a promising approach for learning latent independent components (ICs). iVAEs use auxiliary covariates to build an identifiable generation structure from covariates to ICs to observations, and the posterior network a…

Kernel-convoluted Deep Neural Networks with Data Augmentation

AAAI 2021technical

The Mixup method, which uses linearly interpolated data, has emerged as an effective data augmentation tool to improve generalization performance and the robustness to adversarial examples. The motivation is to curtail undesirable oscillations by its implicit model constraint to behave linearly at i…

Lipschitz Continuous Autoencoders in Application to Anomaly Detection

AISTATS 2020poster

Anomaly detection is the task of finding abnormal data that are distinct from normal behavior. Current deep learning-based anomaly detection methods train neural networks with normal data alone and calculate anomaly scores based on the trained model. In this work, we formalize current practices, bui…
