Out of Distribution Reasoning by Weakly-Supervised Disentangled Logic Variational Autoencoder

no code implementations18 Oct 2022 Zahra Rahiminasab, Michael Yuhas, Arvind Easwaran

Our framework consists of three steps: partitioning data based on observed generative factors, training a VAE as a logic tensor network that satisfies disentanglement rules, and run-time OOD reasoning.

Efficient Out-of-Distribution Detection Using Latent Space of $β$-VAE for Cyber-Physical Systems

no code implementations26 Aug 2021 Shreyas Ramakrishna, Zahra Rahiminasab, Gabor Karsai, Arvind Easwaran, Abhishek Dubey

In this paper, we study this problem as a multi-labeled time series OOD detection problem over images, where the OOD is defined both sequentially across short time windows (change points) as well as across the training data distribution.

Out-of-Distribution Detection in Multi-Label Datasets using Latent Space of $β$-VAE

no code implementations10 Mar 2020 Vijaya Kumar Sundar, Shreyas Ramakrishna, Zahra Rahiminasab, Arvind Easwaran, Abhishek Dubey

We use the fact that compact latent space generated by an appropriately selected $\beta$-VAE will encode the information about these factors in a few latent variables, and that can be used for computationally inexpensive detection.
