Abstract: Technical solutions relate to the field of big data technologies. A technical solution includes: pre-training a time series prediction model using first historical regional heat data; and taking second historical regional heat data as a second support set, and further training the time series prediction model using the second support set to adjust model parameters, so as to obtain the regional heat prediction model; and the regional heat prediction model is configured to predict a second query set, and the second query set includes regional heat at a prediction time.
