Abstract
Analiza i ekstrakcija znanja iz velikih prostorno-vremenskih skupova podataka sve su više zastupljeni kako u istraživačkim radovima tako i u stvarnim programskim rješenjima. U ovom radu analizirani su modeli strojnog učenja koji iskorištavaju postojanje prostorne i vremenske heterogenosti u podacima. U radu je implementiran raspodijeljeni model prostorno-vremenski ponderirane regresije (GTWR) korištenjem platforme Apache Spark. Arhitektura tog modela ne omogućava efektivnu stvarnovremensku obradu velikih skupova podataka u računalnom grozdu. Stoga je u radu predložen te implementiran raspodijeljeni model prostorno-vremenski grupirane regresije (GTCR) koji umjesto postupka ponderiranja koristi algoritam grupiranja kako bi opisao prostornu i vremensku nestacionarnost podataka. Naposljetku, modeli su isprobani i uspoređeni na stvarnom skupu podataka koji opisuje koncentracije najučestalijih onečišćivača zraka sa 12 mjernih postaja u Pekingu kroz period od 2013. do 2017. godine.
Abstract (english)
Analysis and data mining performed on big spatio-temporal datasets is more and more frequent topic both in research and the software development. Machine learning models analysed in this paper take advantage of the spatio-temporal heterogeneity in the data. The paper covers the implementation of the Geo-Temporally Weighted Regression (GTWR) distributed machine learning model using the Apache Spark platform. This model does not support the effective near-real-time computation in cluster. Geo-Temporally Clustered Regression (GTCR) model was introduced in this paper to accommodate the need of the machine learning model which can describe the spatio-temporal non-stationarity in large datasets. Finally, models are tested and compared using the real-world dataset which consists of measurements of most common air pollutants from 12 stations in Beijing in a period from 2013 to 2017.
