Diverse Ensembles Improve Calibration

2020 · arXiv (Cornell University)

Modern deep neural networks can produce badly calibrated predictions, especially when train and test distributions are mismatched. Training an ensemble of models and averaging their predictions can help alleviate these issues. We propose a simple …

Nudging Neural Click Prediction Models to Pay Attention to Position

2023

Predicting the click-through rate (CTR) of an item is a fundamental task in online advertising and recommender systems. CTR prediction models are typically trained on user click data from traffic logs. However, users are more …
