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.

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.

On the Importance of Critical Period in Multi-stage Reinforcement Learning

no code implementations9 Aug 2022 Junseok Park, Inwoo Hwang, Min Whoo Lee, Hyunseok Oh, Minsu Lee, Youngki Lee, Byoung-Tak Zhang

The initial years of an infant's life are known as the critical period, during which the overall development of learning performance is significantly impacted due to neural plasticity.

Toddler-Guidance Learning: Impacts of Critical Period on Multimodal AI Agents

no code implementations12 Jan 2022 Junseok Park, Kwanyoung Park, Hyunseok Oh, Ganghun Lee, Minsu Lee, Youngki Lee, Byoung-Tak Zhang

To validate this hypothesis, we adapt this notion of critical periods to learning in AI agents and investigate the critical period in the virtual environment for AI agents.

Learning task-agnostic representation via toddler-inspired learning

no code implementations27 Jan 2021 Kwanyoung Park, Junseok Park, Hyunseok Oh, Byoung-Tak Zhang, Youngki Lee

One of the inherent limitations of current AI systems, stemming from the passive learning mechanisms (e. g., supervised learning), is that they perform well on labeled datasets but cannot deduce knowledge on their own.
