DUEL: Duplicate Elimination on Active Memory for Self-Supervised Class-Imbalanced Learning

no code implementations14 Feb 2024 Won-Seok Choi, Hyundo Lee, Dong-Sig Han, Junseok Park, Heeyeon Koo, Byoung-Tak Zhang

Recent machine learning algorithms have been developed using well-curated datasets, which often require substantial cost and resources.

Learning Geometry-aware Representations by Sketching

no code implementations CVPR 2023 Hyundo Lee, Inwoo Hwang, Hyunsung Go, Won-Seok Choi, Kibeom Kim, Byoung-Tak Zhang

Our method, coined Learning by Sketching (LBS), learns to convert an image into a set of colored strokes that explicitly incorporate the geometric information of the scene in a single inference step without requiring a sketch dataset.

DUEL: Adaptive Duplicate Elimination on Working Memory for Self-Supervised Learning

no code implementations31 Oct 2022 Won-Seok Choi, Dong-Sig Han, Hyundo Lee, Junseok Park, Byoung-Tak Zhang

In Self-Supervised Learning (SSL), it is known that frequent occurrences of the collision in which target data and its negative samples share the same class can decrease performance.

Deep Quotient Manifold Modeling

no code implementations1 Jan 2021 Jiseob Kim, Seungjae Jung, Hyundo Lee, Byoung-Tak Zhang

One of the difficulties in modeling real-world data is their complex multi-manifold structure due to discrete features.

Unbiased learning with State-Conditioned Rewards in Adversarial Imitation Learning

no code implementations1 Jan 2021 Dong-Sig Han, Hyunseo Kim, Hyundo Lee, Je-Hwan Ryu, Byoung-Tak Zhang

The formulation draws a strong connection between adversarial learning and energy-based reinforcement learning; thus, the architecture is capable of recovering a reward function that induces a multi-modal policy.

Message Passing Adaptive Resonance Theory for Online Active Semi-supervised Learning

no code implementations2 Dec 2020 Taehyeong Kim, Injune Hwang, Hyundo Lee, Hyunseo Kim, Won-Seok Choi, Joseph J. Lim, Byoung-Tak Zhang

Active learning is widely used to reduce labeling effort and training time by repeatedly querying only the most beneficial samples from unlabeled data.

Manifold Learning and Alignment with Generative Adversarial Networks

no code implementations25 Sep 2019 Jiseob Kim, Seungjae Jung, Hyundo Lee, Byoung-Tak Zhang

We present a generative adversarial network (GAN) that conducts manifold learning and alignment (MLA): A task to learn the multi-manifold structure underlying data and to align those manifolds without any correspondence information.

Encoder-Powered Generative Adversarial Networks

no code implementations3 Jun 2019 Jiseob Kim, Seungjae Jung, Hyundo Lee, Byoung-Tak Zhang

We present an encoder-powered generative adversarial network (EncGAN) that is able to learn both the multi-manifold structure and the abstract features of data.
