Recent years have witnessed a paradigm shift in forecasting techniques and applications, from computer-assisted model- and assumption-based to data-driven and fully-automated. This shift can be attributed to the availability of large, rich, and diverse time series data sources, posing unprecedented challenges to traditional time series forecasting methods. As such, how can we build statistical models to efficiently and effectively learn to forecast from large and diverse data sources? How can we leverage the statistical power of \"similar\" time series to improve forecasts in the case of limited observations? What are the implications for building forecasting systems that can handle large data volumes?<\/jats:p>\n          <jats:p>The objective of this tutorial is to provide a concise and intuitive overview of the most important methods and tools available for solving large-scale forecasting problems. We review the state of the art in three related fields: (1) classical modeling of time series, (2) scalable tensor methods, and (3) deep learning for forecasting. Further, we share lessons learned from building scalable forecasting systems. While our focus is on providing an intuitive overview of the methods and practical issues, we also present technical details underlying these powerful tools.<\/jats:p>","DOI":"10.14778\/3229863.3229878","type":"journal-article","created":{"date-parts":[[2018,9,10]],"date-time":"2018-09-10T12:12:28Z","timestamp":1536581548000},"page":"2102-2105","source":"Crossref","is-referenced-by-count":57,"title":["Forecasting big time series"],"prefix":"10.14778","volume":"11","author":[{"given":"Christos","family":"Faloutsos","sequence":"first","affiliation":[{"name":"CMU and Amazon Research"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan","family":"Gasthaus","sequence":"additional","affiliation":[{"name":"Amazon AI Labs"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tim","family":"Januschowski","sequence":"additional","affiliation":[{"name":"Amazon AI Labs"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuyang","family":"Wang","sequence":"additional","affiliation":[{"name":"Amazon AI Labs"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2018,8]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.14778\/3137765.3137775"},{"key":"e_1_2_1_2_1","unstructured":"G.
