We propose here a novel approach to preference learning that interleaves Gaussian Processes (GP) and Robust Ordinal Regression (ROR). A Gaussian process gives a probability distribution on the latent function values that generate users\u2019 preferences. Our method extends the traditional non-parametric Gaussian process framework by approximating the latent function by a very flexible parameterized function, that we call \u03b8-additive function, where \u03b8 is the parameter set. The set \u03b8 reflects the degree of sophistication of the generalized additive model that can potentially represent the user\u2019s preferences. To learn what are the components of \u03b8, we update a probability distribution on the space of all possible sets \u03b8, depending on the ability of the parameterized function to approximate the latent function. We predict pairwise preferences by using the parameter set \u03b8 that maximizes the posterior distribution and by performing robust ordinal regression based on this parameter set. Experimental results on synthetic data demonstrate the effectiveness and robustness of our proposed methodology.<\/jats:p>","DOI":"10.3233\/faia230351","type":"book-chapter","created":{"date-parts":[[2023,9,29]],"date-time":"2023-09-29T09:09:58Z","timestamp":1695978598000},"source":"Crossref","is-referenced-by-count":0,"title":["A Hybrid Approach to Preference Learning with Interaction Terms"],"prefix":"10.3233","author":[{"given":"Hugo","family":"Gilbert","sequence":"first","affiliation":[{"name":"LAMSADE, PSL, Universit\u00e9 Paris-Dauphine, CNRS, Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohamed","family":"Ouaguenouni","sequence":"additional","affiliation":[{"name":"Sorbonne Universit\u00e9, CNRS, LIP6, Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Meltem","family":"\u00d6zt\u00fcrk","sequence":"additional","affiliation":[{"name":"LAMSADE, PSL, Universit\u00e9 Paris-Dauphine, CNRS, Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Olivier","family":"Spanjaard","sequence":"additional","affiliation":[{"name":"Sorbonne Universit\u00e9, CNRS, LIP6, Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","ECAI 2023"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/FAIA230351","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,29]],"date-time":"2023-09-29T09:09:59Z","timestamp":1695978599000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/FAIA230351"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,9,28]]},"ISBN":["9781643684369","9781643684376"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/faia230351","relation":{},"ISSN":["0922-6389","1879-8314"],"issn-type":[{"value":"0922-6389","type":"print"},{"value":"1879-8314","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,9,28]]}}}
