AdaptiveRec: Adaptively Construct Pairs for Contrastive Learning in Sequential Recommendation
Jaeheyoung Jeon, Jung Hyun Ryu, Jewoong Cho +1
This paper presents a solution to the challenges faced by contrastive learning in sequential recommendation systems. In particular, it addresses the issue of false negative, which…
Fisher-Weighted Merge of Contrastive Learning Models in Sequential Recommendation
Jung Hyun Ryu, Jaeheyoung Jeon, Jewoong Cho +1
Along with the exponential growth of online platforms and services, recommendation systems have become essential for identifying relevant items based on user preferences. The domai…
AnomalyBERT: Self-Supervised Transformer for Time Series Anomaly Detection using Data Degradation Scheme
Yungi Jeong, Eunseok Yang, Jung Hyun Ryu +2
Mechanical defects in real situations affect observation values and cause abnormalities in multivariate time series, such as sensor values or network data. To perceive abnormalitie…
Meta-Learning with Adaptive Weighted Loss for Imbalanced Cold-Start Recommendation
Minchang Kim, Yongjin Yang, Jung Hyun Ryu +1
Sequential recommenders have made great strides in capturing a user's preferences. Nevertheless, the cold-start recommendation remains a fundamental challenge as they typically inv…
