  • Publication number: 20230237373
    Abstract: An information processing device includes a hardware processor. The processor functions to generate first data to be input to a model used for deducing an effect of a case where a measure is executed with input of observation data. The first data represents the observation data obtained without execution of the measure. The processor functions to receive first parameters affecting the effect. Each first parameter is used in an estimation process of estimating the observation data when the measure is executed. The processor functions to execute the estimation process and generate second data representing the observation data. The processor functions to estimate the effect by using the first/second data. The processor functions to learn the model by using the first/second data. The processor functions to evaluate performance of the learned model by comparing the effect estimated by using the first/second data and the effect estimated by the learned model.

  • Patent number: 8924324
    Abstract: According to one embodiment, a behavior estimation apparatus includes a storage unit, a first calculation unit, a second calculation unit, and an estimation unit. The storage unit stores first data collecting power values consumed by a consumer in a period. The first calculation unit calculates second data representing a frequency of each power value by using the first data. The second calculation unit calculates a first threshold to divide a first power value from a second power value which is larger than and next to the first power value, among power values corresponding to maximal values of frequencies included in the second data. The estimation unit obtains a power value consumed by the consumer in an estimating period, and estimates the consumer's behavior status in the estimating period by using the power value and the first threshold.

  • Patent number: 8224685
    Abstract: The invention provides a personal behavior analysis apparatus capable of statistically analyzing a personal behavior. To analyze personal behaviors, a population data file is provided that stores flow-line data for individual persons as a population acquired by tracking the behaviors of persons within a monitored area. After input of a condition for narrowing down the flow-line data as analysis objects is accepted via a condition input section, the population data file is searched based on the condition and flow-line data meeting the condition is acquired. The acquired flow-line data is stored in a subpopulation data file as a subpopulation. A control section of the apparatus calculates statistics values related to personal behavior analysis using the flow-line data stored in the subpopulation data file and displays them on a display section.

  • Publication number: 20090257624
    Abstract: A control section edits a complete flow line as an entire trajectory in a sales area for each customer, based on data for a flow line generated from a camera image obtained by shooting the sales area. The complete flow line is reproduced as trajectories of customers by a display section. The control section accepts input of information on transaction settlements by the customers. When the information is input through an input section, it is added to the complete flow line data of the customers being reproduced and is stored into a complete flow line database. The control section matches the complete flow line data stored in the complete flow line database with transaction data specified by the information on the transaction settlements added to the complete flow line data.
