Generalized Contrastive Divergence: Joint Training of Energy-Based Model and Diffusion Model through Inverse Reinforcement Learning

no code implementations6 Dec 2023 Sangwoong Yoon, Dohyun Kwon, Himchan Hwang, Yung-Kyun Noh, Frank C. Park

We present Generalized Contrastive Divergence (GCD), a novel objective function for training an energy-based model (EBM) and a sampler simultaneously.

A Statistical Manifold Framework for Point Cloud Data

no code implementations29 Sep 2021 Yonghyeon LEE, Seungyeon Kim, Jinwon Choi, Frank C. Park

The only requirement on the part of the user is the choice of a meaningful underlying probability distribution, which is more intuitive and natural to make than what is required in existing ad hoc formulations.

Regularized Autoencoders for Isometric Representation Learning

no code implementations ICLR 2022 Yonghyeon LEE, Sangwoong Yoon, MinJun Son, Frank C. Park

The recent success of autoencoders for representation learning can be traced in large part to the addition of a regularization term.

Adversarial Distributions Against Out-of-Distribution Detectors

no code implementations29 Sep 2021 Sangwoong Yoon, Jinwon Choi, Yonghyeon LEE, Yung-Kyun Noh, Frank C. Park

As an outlier may deviate from the training distribution in unexpected ways, an ideal OOD detector should be able to detect all types of outliers.

Out of Distribution (OOD) Detection

Suppressing Outlier Reconstruction in Autoencoders for Out-of-Distribution Detection

no code implementations1 Jan 2021 Sangwoong Yoon, Yung-Kyun Noh, Frank C. Park

This phenomenon, which we refer to as outlier reconstruction, has a detrimental effect on the use of autoencoders for outlier detection, as an autoencoder will misclassify a clear outlier as being in-distribution.

Efficient Neural Network Compression via Transfer Learning for Industrial Optical Inspection

no code implementations20 Oct 2018 Seunghyeon Kim, Yung-Kyun Noh, Frank C. Park

In this paper, we investigate learning the deep neural networks for automated optical inspection in industrial manufacturing.

A Linear-Time Variational Integrator for Multibody Systems

1 code implementation9 Sep 2016 Jeongseok Lee, C. Karen Liu, Frank C. Park, Siddhartha S. Srinivasa

Our key contribution is to derive a recursive algorithm that evaluates DEL equations in $O(n)$, which scales up well for complex multibody systems such as humanoid robots.
