            Abstract
            The signaling and APP data from mobile phones, as the most representative
            type of data among the spatial big data, enable the population analysis based
            on  the  personal  behavior  of  mobile  phone.  By  combining  the  traditional
            statistical method with the AI deep learning technology, this paper uses the
            time series correlation, spatial sequence correlation and deep residual model
            to predict the population size, and good results have been achieved. As the
            change in population size is periodic in time, the short-term prediction effect
            is good, but the effect brought by periodicity should be eliminated for the
            long-term prediction.

            1.  Introduction
                In  recent  years,  with  the  rapid  development  of  mobile  internet
            technology,  mobile  phones  have  become  indispensable  items  in  people’s
            daily life. The signalling data and APP usage records from mobile phones, as
            the most representative type of data among the spatial big data, record the
            massive and diversified crowd time and space location information at short
            intervals, enable the analysis of urban spatial characteristics based on the
            personal behaviour of mobile phone and are of great significance for urban
            planning, transportation, public resource allocation, and business information
            mining, etc. By combining the traditional statistical method with the AI deep
            learning  technology,  this  paper  uses  the  time  series  correlation,  spatial
            sequence correlation and deep residual model to predict the population size.

            2.  Methodology
            (1)   Using the time series correlation
                 If the time during a day is divided into several time periods  ,   , ⋯ ,  
                                                                                     
                                                                           1
                                                                               2
            by 10min, 30min or 60min, the time series correlation model can be used to
            predict the population size in this area. If it is assumed that the population
            size at the next time period is related to that at the previous p time periods,
