Dynamic Multi-Behavior Sequence Modeling for Next Item Recommendation

no code implementations28 Jan 2023 Junsu Cho, Dongmin Hyun, Dong won Lim, Hyeon jae Cheon, Hyoung-iel Park, Hwanjo Yu

To this end, we first address the characteristics of multi-behavior sequences that should be considered in SRSs, and then propose novel methods for Dynamic Multi-behavior Sequence modeling named DyMuS, which is a light version, and DyMuS+, which is an improved version, considering the characteristics.

Sparse Network Inversion for Key Instance Detection in Multiple Instance Learning

no code implementations7 Sep 2020 Beomjo Shin, Junsu Cho, Hwanjo Yu, Seungjin Choi

Since a positive bag contains both positive and negative instances, it is often required to detect positive instances (key instances) when a set of instances is categorized as a positive bag.
