Provided is a data prediction system for predicting a future prediction value. The data prediction system has a data management device which manages data and a prediction operation device which models tendency of an error amount of a prediction operation result calculated on the basis of a correlation with a major explanatory variable and corrects a future prediction value. The data management device includes a storage unit which stores prediction target past measurement data observed with a time transition and explanatory factor data explaining the prediction target past measurement data. The prediction operation device includes a first prediction operation unit which performs prediction on the basis of a correlation between the prediction target past measurement data and the explanatory factor data, a second prediction operation unit which models tendency of an error of an operation result of the first prediction operation unit and performs future error amount prediction of the operation result of the first prediction operation unit, and a correction unit which corrects the operation result of the first prediction operation unit by an operation result of the second prediction operation unit.

Data prediction system and data prediction method

A data processing system calculates prediction or planning data of an object from observation data of a calculation object of the prediction or planning data and observation data of various factors, including a first processing section which identifies a model used for calculation of the prediction or planning data of each of the factors, a second processing section which calculates data which indices the kind of a time transition of the factor from the observation data of the factor and classifies the observation data of the factor by using the calculated data which indicates the kind of the time transition, and a third processing section which changes the model for calculation of the prediction or planning data on the basis of the classified observation data and the prediction data of the factor in a prediction or planning data calculation object time period and calculates the prediction or planning data.

Data processing system and data processing method

To propose an information processing device and method capable of planning an effective scheme, such as distributing information appropriate to a user. Time-series positional data composed of time-series positional information of a mobile communication body are collected, and a regular behavior of a user of the mobile communication body is estimated on the basis of the collected time-series positional data of the mobile communication body.

Information processing device and method

Proposed are an information distribution apparatus and method capable of efficiently distributing information. Clustering processing of collecting time series position data, which is configured from position information of a plurality of mobile communication objects, and classifying the time series position data into a plurality of clusters based on the collected time series position data of each of the mobile communication objects is executed, profiling processing of determining, for each of the clusters, a dominant attribute of each user in which the time series position data was allocated to the relevant cluster based on pre-registered attribute information of each of the users of each of the mobile communication objects is executed, and, for each of the clusters, information to be distributed to each of the users in which the time series position data was allocated to the relevant cluster is determined based on a processing result of the profiling processing.

Information distribution apparatus and method

While gas in a general storage container with no gas inlet and in the storage container with the gas inlet is replaced in a short time, the semiconductor wafer surface is cleaned. In an apparatus for replacing gas in a semiconductor wafer storage container which includes a lid unit and a storage container main body with a gas inlet, the apparatus includes gas introducing means for introducing the gas into the storage container main body, gas evacuating means for evacuating the gas in the storage container main body, and gas circulating means for circulating the gas in the storage container main body through a chemical adsorption filter. Gas introducing means for introducing the gas from a gap between the storage container main body and the lid unit while the lid unit is opened in the storage container mounting means is provided in the storage container with no gas inlet.
