The results derived from random forest algorithm showed that with a large number of attributes, that have a high correlation with the examined question the random forest algorithm was able to determine estimations of asbestos use in each municipality.\nAsbestos amounts were noticed to correlate with built area of all buildings dating from 1921 to 1989. There was significant bias towards the building age, since most of the asbestos was used during 1960-70. Since small residential buildings dominated the data other building types were not found as significant correlators when estimating municipal-scale asbestos use.\nThe main problems of this study were the absence of accurate statistics of asbestos use in construction materials, which created uncertainties with the data. This uncertainty was accepted and data was imputed and evaluated with accurate statistical building data.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2021-01-20T07:07:46Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2021-01-20T07:07:46Z (GMT).
