Such simulations generate large ensembles of multivariate, multiattribute time series. Comprehensive understanding of this data requires techniques that support the multivariate nature of the time series and can compare behaviors that are both periodic and non-periodic across multiple time scales and multiple time series themselves. In this paper, we present a novel technique to extract such patterns from time series generated from simulations of seismic responses. The core of our approach is the use of topic modeling, where topics correspond to interpretable and discriminative features of the earthquakes. We transform the raw time series data into a time series of topics, and use this visual summary to compare temporal patterns in earthquakes, query earthquakes via the topics across arbitrary time scales, and enable details on demand by linking the topic visualization with the original earthquake data. We show, through a surrogate task and an expert study, that this technique allows analysts to more easily identify recurring patterns in such time series. By integrating this technique in a prototype system, we show how it enables novel forms of visual interaction.<\/jats:p>","DOI":"10.1177\/14738716211038618","type":"journal-article","created":{"date-parts":[[2021,8,21]],"date-time":"2021-08-21T07:19:18Z","timestamp":1629530358000},"page":"263-282","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["STFT-LDA: An algorithm to facilitate the visual analysis of building seismic responses"],"prefix":"10.1177","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5804-2815","authenticated-orcid":false,"given":"Zhenge","family":"Zhao","sequence":"first","affiliation":[{"name":"Department of Computer Science at the University of Arizona, Tucson, AZ, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Danilo","family":"Motta","sequence":"additional","affiliation":[{"name":"University of S\u00e3o Paulo, Sao Carlos, S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthew","family":"Berger","sequence":"additional","affiliation":[{"name":"Vanderbilt University, Nashville, TN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joshua A","family":"Levine","sequence":"additional","affiliation":[{"name":"Department of Computer Science at the University of Arizona, Tucson, AZ, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ismail B","family":"Kuzucu","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering at the University of Arizona, Tucson, AZ, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert B","family":"Fleischman","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering at the University of Arizona, Tucson, AZ, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Afonso","family":"Paiva","sequence":"additional","affiliation":[{"name":"University of S\u00e3o Paulo, Sao Carlos, S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos","family":"Scheidegger","sequence":"additional","affiliation":[{"name":"Department of Computer Science at the University of Arizona, Tucson, AZ, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2021,8,21]]},"reference":[{"key":"bibr1-14738716211038618","volume-title":"2018 international building code","author":"ICC","year":"2017"},{"key":"bibr2-14738716211038618","doi-asserted-by":"publisher","DOI":"10.1061\/(ASCE)ST.1943-541X.0001972"},{"key":"bibr3-14738716211038618","volume-title":"Risk management series: designing for earthquakes - a manual for architects (Fema 454\/december 2006).
