Position Bias Estimation with Item Embedding for Sparse Dataset

no code implementations10 May 2023 Shion Ishikawa, Yun Ching Liu, Young-joo Chung, Yu Hirate

Using a public dataset and internal carousel advertisement click dataset, we empirically show that item embedding with Latent Semantic Indexing (LSI) and Variational Auto-Encoder (VAE) improves the accuracy of position bias estimation and the estimated position bias enhances Learning to Rank performance.

Learning Classifiers on Positive and Unlabeled Data with Policy Gradient

1 code implementation15 Oct 2019 Tianyu Li, Chien-Chih Wang, Yukun Ma, Patricia Ortal, Qifang Zhao, Bjorn Stenger, Yu Hirate

Existing algorithms aiming to learn a binary classifier from positive (P) and unlabeled (U) data generally require estimating the class prior or label noises ahead of building a classification model.
