To fill this gap, we introduce Tile2Vec, an unsupervised representation learning algorithm that extends the distributional hypothesis from natural language \u2014 words appearing in similar contexts tend to have similar meanings \u2014 to spatially distributed data. We demonstrate empirically that Tile2Vec learns semantically meaningful representations for both image and non-image datasets. Our learned representations significantly improve performance in downstream classification tasks and, similarly to word vectors, allow visual analogies to be obtained via simple arithmetic in the latent space.<\/jats:p>","DOI":"10.1609\/aaai.v33i01.33013967","type":"journal-article","created":{"date-parts":[[2019,9,4]],"date-time":"2019-09-04T07:32:51Z","timestamp":1567582371000},"page":"3967-3974","source":"Crossref","is-referenced-by-count":114,"title":["Tile2Vec: Unsupervised Representation Learning for Spatially Distributed Data"],"prefix":"10.1609","volume":"33","author":[{"given":"Neal","family":"Jean","sequence":"first","affiliation":[]},{"given":"Sherrie","family":"Wang","sequence":"additional","affiliation":[]},{"given":"Anshul","family":"Samar","sequence":"additional","affiliation":[]},{"given":"George","family":"Azzari","sequence":"additional","affiliation":[]},{"given":"David","family":"Lobell","sequence":"additional","affiliation":[]},{"given":"Stefano","family":"Ermon","sequence":"additional","affiliation":[]}],"member":"9382","published-online":{"date-parts":[[2019,7,17]]},"container-title":["Proceedings of the AAAI Conference on Artificial Intelligence"],"original-title":[],"link":[{"URL":"https:\/\/ojs.aaai.org\/index.php\/AAAI\/article\/download\/4288\/4166","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/ojs.aaai.org\/index.php\/AAAI\/article\/download\/4288\/4166","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,11,7]],"date-time":"2022-11-07T06:35:07Z","timestamp":1667802907000},"score":1,"resource":{"primary":{"URL":"https:\/\/ojs.aaai.org\/index.php\/AAAI\/article\/view\/4288"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,7,17]]},"references-count":0,"journal-issue":{"issue":"01","published-online":{"date-parts":[[2019,7,23]]}},"URL":"https:\/\/doi.org\/10.1609\/aaai.v33i01.33013967","relation":{},"ISSN":["2374-3468","2159-5399"],"issn-type":[{"value":"2374-3468","type":"electronic"},{"value":"2159-5399","type":"print"}],"subject":[],"published":{"date-parts":[[2019,7,17]]}}}
