Since 1999, Estonia has conducted the National Forest Inventory (NFI) on the basis of sample plots. This paper presents a new module, incorporating remote-sensing feature variables from airborne laser scanning (ALS) and from multispectral satellite i

The usage of mobile phones has become an important activity in our lives. The passive mobile positioning of mobiles provides large-scale data about human mobility. Hence, in this paper, we are presenting a technique based on continuous time switching

In passive mobile positioning, the cell-level measurements must be translated into a geographical location, which can be expressed as spatial probability density function (SPDF). In this paper, we present the results of a study where we compared diff

Masinõppemudelid eeldavad, et andmed pärinevad statsionaarsest jaotusest.Praktikas on tihti vaja mudelitega tõlgendada andmeid, mis pärinevad kiiresti dünaamiliselt muutuvast andmevoost. Seda muutust õppe- ja testvalimis nimetatakse kontseptuaa

Mobiilioperaatorid koguvad andmeid oma klientide tegevuse kohta mobiilivõrgus. Igal võrgusündmusel on viide mastile, mille külge oli seade parasjagu ühendatud. Teades mastide kattealasid, saab hinnata inimeste trajektoore läbi terve päeva. Nen
