Transparent, Scrutable and Explainable User Models for Personalized Recommendation. improved the system performance. Prior works that have focused on paths connecting users and items in a heterogeneous network have several limitations, such as discovering . To address these issues, we propose a novel reinforcement learning method, namely model-based counterfactual advantage learning (MBCAL). One way to address this is via reinforcement learning. Recommender system aims to provide personalized recommendation for users in a wide spectral of online applications, including e-commerce, search engines, and social media, by predicting the users' preference over items. Several methods for off-policy or counterfactual learning have been proposed in recent years, but their efficacy for the recommendation task remains understudied.

This work is illustrated by experiments on the ad placement system associated with the Bing search engine. Introduction Statistical machine learning technologies in the real world are never without a purpose. Recommendation is a prevalent and critical service in information systems. Personalized recommendation is typically solved as a machine learning task where the recommender models learn to rank items from users' historical behaviors. More information here. ABSTRACT Many information systems engage with their users through the following loop of interactions: the system receives a context as input (e.g. Based on logged data from a certain policy (recommender), we want to predict what the performance would have been if an-other policy had been deployed. Postdoctoral Researcher, University of Antwerp. 2. Provider-side Interpretability with Counterfactual Explanations in Recommender Systems Interpretable explanations for recommender systems and other machine learning models are crucial to gain user trust. Adversarial Counterfactual Learning and Evaluation for Recommender System. During training, we perform multi-task learning to achieve the contribution of each cause; during testing, we perform counterfactual inference to remove the effect of item popularity. To provide personalized suggestions to users . improved the system performance. In this paper, we develop an alternative method, which predicts the performance of algorithms given historical data that may have been generated by a . Though it is helpful in item recommendation and model training, the closed feedback loop may lead to the so-called bias problems, including the position bias, selection bias and popularity bias.
