SymCERE: Symmetric Contrastive Learning for Robust Review-Enhanced Recommendation
Toyotaro Suzumura, Hisashi Ikari, Hiroki Kanezashi +2
Modern recommendation systems fuse user behavior graphs and review texts but often encounter a "Fusion Gap" caused by False Negatives, Popularity Bias, and Signal Ambiguity. We pro…
Annealing Machine-assisted Learning of Graph Neural Network for Combinatorial Optimization
Pablo Loyola, Kento Hasegawa, Andres Hoyos-Idobro +4
While Annealing Machines (AM) have shown increasing capabilities in solving complex combinatorial problems, positioning themselves as a more immediate alternative to the expected a…
Position Bias Estimation with Item Embedding for Sparse Dataset
Shion Ishikawa, Yun Ching Liu, Young-Joo Chung +1
Estimating position bias is a well-known challenge in Learning to Rank (L2R). Click data in e-commerce applications, such as targeted advertisements and search engines, provides im…
