Weakly Supervised Temporal Anomaly Segmentation with Dynamic Time Warping

1 code implementation ICCV 2021 Dongha Lee, Sehun Yu, Hyunjun Ju, Hwanjo Yu

Most recent studies on detecting and localizing temporal anomalies have mainly employed deep neural networks to learn the normal patterns of temporal data in an unsupervised manner.

Bootstrapping User and Item Representations for One-Class Collaborative Filtering

no code implementations13 May 2021 Dongha Lee, SeongKu Kang, Hyunjun Ju, Chanyoung Park, Hwanjo Yu

To make the representations of positively-related users and items similar to each other while avoiding a collapsed solution, BUIR adopts two distinct encoder networks that learn from each other; the first encoder is trained to predict the output of the second encoder as its target, while the second encoder provides the consistent targets by slowly approximating the first encoder.

One-class Classification Robust to Geometric Transformation

no code implementations1 Jan 2021 Hyunjun Ju, Dongha Lee, SeongKu Kang, Hwanjo Yu

Recent studies on one-class classification have achieved a remarkable performance, by employing the self-supervised classifier that predicts the geometric transformation applied to in-class images.
