In this work, We propose a technique that joint interpretations into recommendation training to make accurate predictions while at the same time learning to produce recommendations which have the most explanatory utility to the user. Our evaluation shows that we can jointly learn to make accurate and meaningful explanations with only a small sacrifice in recommendation accuracy. We also develop a new algorithm to measure explanation fidelity for the interpretation of top-n rankings. We prove that our approach can form the basis of a universal approach to explanation generation in recommender systems.||Funding Details:||Science Foundation Ireland||Type of material:||Conference Publication||Publisher:||ACM||Start page:||247||End page:||249||Copyright (published version):||2019 the Authors||Keywords:||Recommender systems; Learn to rank; Interpretation; Explanations||DOI:||10.1145/3314183.3323457||Other versions:||http://www.cyprusconferences.org/umap2019/||Language:||en||Status of Item:||Peer reviewed||Is part of:||UMAP'19 Adjunct Adjunct Publication of the 27th Conference on User Modeling, Adaptation and Personalization||Conference Details:||UMAP'19: 27th Conference on User Modeling, Adaptation and Personalization, Larnaca, Cyprus, 9-12 June 2019||ISBN:||978-1-4503-6711-0|
