Such pre-fitting has the purpose of improving the fitting time for a given Hidden Markov Model (HMM) while maintaining the original Baum\u2013Welch algorithm as the fitting one. The fitting time is improved by avoiding the Baum\u2013Welch algorithm sensitiveness through the generation of parameters closer to the global maximum likelihood. Furthermore, by keeping the original Baum\u2013Welch algorithm as the fitting one, we guarantee that all related methods will continue to work properly. On the other hand, the pre-fitting generates the HMM parameters directly derived from time-series data, without any data transformation, using an [Formula: see text] operation.<\/jats:p>","DOI":"10.1142\/s0218194019400242","type":"journal-article","created":{"date-parts":[[2020,2,12]],"date-time":"2020-02-12T08:53:07Z","timestamp":1581497587000},"page":"1835-1850","source":"Crossref","is-referenced-by-count":1,"title":["Piecewise Aggregation for HMM Fitting: A Pre-Fitting Model for Seamless Integration with Time-Series Data"],"prefix":"10.1142","volume":"29","author":[{"given":"Joaquim","family":"Assun\u00e7\u00e3o","sequence":"first","affiliation":[{"name":"Department of Applied Computing, Federal University of Santa Maria, Avenida Roraima 1000, Santa Maria, RS, CEP: 97105-900, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paulo","family":"Fernandes","sequence":"additional","affiliation":[{"name":"Roberts Wesleyan College, 2301 Westside Dr., Rochester, NY 14624, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean-Marc","family":"Vincent","sequence":"additional","affiliation":[{"name":"LIG, University Grenoble Alpes, 621 Avenue Centrale, Saint-Martin-d\u2019H\u00e9res, 38058 Grenoble Cedex 9, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2020,2,11]]},"reference":[{"key":"S0218194019400242BIB001","doi-asserted-by":"publisher","DOI":"10.1007\/3-540-57301-1_5"},{"key":"S0218194019400242BIB002","doi-asserted-by":"publisher","DOI":"10.1002\/sim.2108"},{"key":"S0218194019400242BIB003","doi-asserted-by":"publisher","DOI":"10.1007\/BF02551353"},{"key":"S0218194019400242BIB004","doi-asserted-by":"publisher","DOI":"10.1162\/neco.1994.6.2.307"},{"key":"S0218194019400242BIB005","doi-asserted-by":"publisher","DOI":"10.1214\/aoms\/1177697196"},{"key":"S0218194019400242BIB006","doi-asserted-by":"publisher","DOI":"10.1016\/S0167-9473(02)00163-9"},{"key":"S0218194019400242BIB007","doi-asserted-by":"publisher","DOI":"10.1109\/ICASSP.1998.681600"},{"key":"S0218194019400242BIB009","doi-asserted-by":"publisher","DOI":"10.1016\/0167-9473(92)90042-E"},{"key":"S0218194019400242BIB010","first-page":"126","volume-title":"Proc. 15th Int.
