  • A STUDY ON ESTIMATING WAKE TIME USING TIME-SERIES ELECTRICITY CONSUMPTION DATA FOR THE CARE OF SINGLE ELDERLY RESIDENTS IN URBAN DWELLINGS

抄録

<p>The purpose of this study was to develop a model for estimating wake time using only time-series electricity consumption data and to verify its accuracy. </p><p>Presence/absence, sleeping/non-sleeping, air conditioner on/off, and electricity consumption data obtained from a survey of 12 single elderly people over a one-year period were used. </p><p>The model classifies people into two categories: active and inactive, and estimates their wake time from the results of the two classifications. </p><p>When the two factors that reduced accuracy were excluded, it was possible to estimate wake times within one hour of estimation error on 278 days of the year.</p>
