Learning from Negative User Feedback and Measuring Responsiveness for Sequential Recommenders

no code implementations23 Aug 2023 Yueqi Wang, Yoni Halpern, Shuo Chang, Jingchen Feng, Elaine Ya Le, Longfei Li, Xujian Liang, Min-Cheng Huang, Shane Li, Alex Beutel, Yaping Zhang, Shuchao Bi

In this work, we incorporate explicit and implicit negative user feedback into the training objective of sequential recommenders in the retrieval stage using a "not-to-recommend" loss function that optimizes for the log-likelihood of not recommending items with negative feedback.

Exemplar Loss for Siamese Network in Visual Tracking

no code implementations20 Jun 2020 Shuo Chang, Yifan Zhang, Sai Huang, Yuanyuan Yao, Zhiyong Feng

In general, Siamese tracking algorithms, supervised by logistic loss and triplet loss, increase the value of inner product between exemplar template and positive sample while reduce the value of inner product with background sample.
