  • Patent number: 8560467
    Abstract: A data processing apparatus includes an obtaining unit for obtaining time-series data, an activity model learning unit for learning an activity model representing a user activity state as a stochastic state transition model from the obtained time-series data, a recognition unit for recognizing a current user activity state by using the learned activity model, and a prediction unit for predicting a user activity state after a predetermined time elapses from a current time from the recognized current user activity state, wherein the prediction unit predicts the user activity state as an occurrence probability, and calculates the occurrence probabilities of the respective states on the basis of the state transition probability of the stochastic state transition model to predict the user activity state, while it is presumed that observation probabilities of the respective states at the respective times of the stochastic state transition model are an equal probability.

  • Publication number: 20130239054
    Abstract: An operation menu display control method for an analyzer is provided which can change the ranking of operation menus to be displayed preferentially in accordance with the frequency of their use by users and which can set operation menus that can be displayed preferentially regardless of the frequency of their use. A storage unit stores a usage count 23 of each of the used operation menus and a usage count ranking 24 with regard to each of the roles played by the users such as a system administrator 20 and an operator 21. Based on the roles of the users who use the analyzer, the method causes a display unit to display the highest-ranked ā€œnā€ operation menus in terms of usage count stored with regard to each user. The operation menus to be displayed on a display means regardless of the frequency of their use are registered beforehand in a registered/unregistered region 25. The registered operation menus are displayed preferentially on a display device regardless of the frequency of their use.

  • Publication number: 20130197890
    Abstract: The present invention relates to a data processing device, a data processing method, and a program which enable prediction to be performed even when there is a gap in the current location data to be obtained in real time. A learning main processor 23 represents movement history data serving as data for learning, as a probability model which represents a user's activity, and obtains a parameter thereof. A prediction main processor 33 uses the probability model obtained by learning to estimate a user's current location from movement history data to be obtained in real time. In the event that there is a data missing portion included in movement history data to be obtained in real time, the prediction main processor 33 generates the data missing portion thereof by interpolation processing, and estimates state nose series corresponding to the interpolated data for prediction.
