Abstract: The value of the real estate investment trust is predicted. A REIT price prediction device 1 includes: a storage unit 10 that stores a prediction model for predicting a future REIT price, the prediction model being generated by learning based on training data comprising sets of input data, which comprises population distribution data regarding the population distribution around each of a plurality of real estate properties in which a REIT (Real Estate Investment Trust) invests, and a REIT price indicating the value of the REIT; an acquisition unit 11 that acquires the input data; and an output unit 13 that outputs the future REIT price obtained by applying the input data acquired by the acquisition unit 11 to the prediction model stored in the storage unit 10.

Abstract: A population involved in actions in the movement destination area is predicted. A purchase predicting device 1 includes: a storage unit 10 that stores a prediction coefficient, which is a probability that a person in a predetermined area will be involved in actions, and an average moving population ratio, which is a probability that a person in a predetermined area will move to a movement destination area that is an area of a movement destination; an acquisition unit 11 that acquires population distribution data regarding a population for each area; and a prediction unit 13 that predicts a population involved in purchasing for each movement destination area based on the population distribution data acquired by the acquisition unit 11 and the prediction coefficient and the average moving population ratio stored in the storage unit 10.

Abstract: A steering control device includes an electronic control unit. The electronic control unit is configured to calculate a target rotation angle of a shaft rotating with a turning operation of turning wheels based on a steering angle of a steering wheel acquired from a rotation angle of a reaction motor, to calculate a command value based on the target rotation angle and a steering torque acquired from a torsion angle of a torsion bar twisting with an operation of the steering wheel, and to compensate for the torsion angle by adding the torsion angle as a compensation value to the steering angle. The electronic control unit is configured to change a value of the torsion angle that is added to the steering angle according to a degree of change of a state variable used to calculate the command value.

Abstract: An analysis device includes: an estimation unit that obtains a current state variable by state estimation based on a state variable for first sequence data generated by applying a first conversion to observation data, a state space model, and each element included in the first sequence data; an observation unit that generates second sequence data by applying an observation process to the current state variable; an elaboration unit that generates third sequence data by performing an elaboration process of correcting each element included in the second sequence data so that a value of each cell of the estimated observation data does not become a negative value and the number of cells having a value other than 0 included in the estimated observation data is suppressed; and a second conversion unit that generates the estimated observation data by applying a second conversion to the third sequence data.
