Teacher-Explorer-Student Learning: A Novel Learning Method for Open Set Recognition

no code implementations23 Mar 2021 Jaeyeon Jang, Chang Ouk Kim

To address this problem, teacher-explorer-student (T/E/S) learning, which adopts the concept of open set recognition (OSR) that aims to reject unknown samples while minimizing the loss of classification performance on known samples, is proposed in this study.

Collective Decision of One-vs-Rest Networks for Open Set Recognition

no code implementations18 Mar 2021 Jaeyeon Jang, Chang Ouk Kim

For this purpose, a novel network structure is proposed, in which multiple one-vs-rest networks (OVRNs) follow a convolutional neural network feature extractor.

Freudian and Newtonian Recurrent Cell for Sequential Recommendation

no code implementations11 Feb 2021 Hoyeop Lee, Jinbae Im, Chang Ouk Kim, Sehee Chung

The predominant sequential recommendation models are based on natural language processing models, such as the gated recurrent unit, that embed items in some defined space and grasp the user's long-term and short-term preferences based on the item embeddings.
