The information processing apparatus (2000) of the example embodiment 1 includes an acquisition unit (2020), a clustering unit (2040), a transformation unit (2060) and modeling unit (2080). Until a predetermined termination condition is determined, the clustering unit (2040) repeatedly preforms: 1) optimizing the posterior parameters for clustering assignment for each data streams; 2) optimizes the posterior parameters for each determined cluster and for each time frame; 3) optimizes the posterior parameters for individual responses for each data stream; 4) optimizes the posterior parameters for latent states, via approximating the observation model through non-conjugate inference. The transformation unit (2060) transforms the latent states into parameters of the observation model, through a transformation function. The modeling unit (2060) generates the model data, which including all the optimized parameters of all the model latent variables, optimized inside the clustering unit (2040).

The invention discloses a seven-parameter conversion method between a national three-dimensional coordinate system and a random local plane coordinate system. The seven-parameter conversion method between the national three-dimensional coordinate system and the random local plane coordinate system aims at the problems that an existing algorithm cannot directly obtain a high-precision single seven-parameter conversion parameter, and further the achievements of a local coordinate system cannot be obtained in real time based on CORS measured data, and provides a seven-parameter convention model to which addition constants are additionally added. According to the method, through a series of data processing methods, the additionally added addition constants greatly decrease the influence of projection deformation; the influence of a geodetic height on parameter solving precision, and the like are decreased through a three-parameter conversion model; the precision of a conversion parameter is greatly improved; moreover, the method accords with the requirement that a measurement handbook in the current market can only accept single four / seven-parameter input; the achievements of a national coordinate system, which are obtained through measurement based on a CORS network, can be converted into the achievements of the local coordinate system in real time; in this way, the expansion of the application spaces of provincial and municipal CORSs in a measurement practice process is facilitated.
