Recently, boosting\r\nvariational inference has been proposed as a new paradigm to approximate the\r\nposterior by a mixture of densities by greedily adding components to the\r\nmixture. However, as is the case with many other variational inference\r\nalgorithms, its theoretical properties have not been studied. In the present\r\nwork, we study the convergence properties of this approach from a modern\r\noptimization viewpoint by establishing connections to the classic Frank-Wolfe\r\nalgorithm. Our analyses yields novel theoretical insights regarding the\r\nsufficient conditions for convergence, explicit rates, and algorithmic\r\nsimplifications. Since a lot of focus in previous works for variational\r\ninference has been on tractability, our work is especially important as a much\r\nneeded attempt to bridge the gap between probabilistic models and their\r\ncorresponding theoretical properties."}],"oa":1,"year":"2018","page":"464-472","main_file_link":[{"url":"https://arxiv.org/abs/1708.01733","open_access":"1"}],"author":[{"id":"26cfd52f-2483-11ee-8040-88983bcc06d4","full_name":"Locatello, Francesco","last_name":"Locatello","orcid":"0000-0002-4850-0683","first_name":"Francesco"},{"last_name":"Khanna","first_name":"Rajiv","full_name":"Khanna, Rajiv"},{"first_name":"Joydeep","last_name":"Ghosh","full_name":"Ghosh, Joydeep"},{"first_name":"Gunnar","last_name":"Rätsch","full_name":"Rätsch, Gunnar"}],"day":"15","language":[{"iso":"eng"}]}
