  • Patent number: 8738555
    Abstract: A data processing device includes a state value calculation unit which calculates a state value of which the value increases as much as a state with a high transition probability for each state of the state transition model, an action value calculation unit which calculates an action value, of which the value increases as a transition probability increases for each state of the state transition model and each action that the agent can perform, a target state setting unit which sets a state with great unevenness in the action value among states of the state transition model to a target state that is the target to reach by action performed by the agent, and an action selection unit which selects an action of the agent so as to move toward the target state.

  • 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: 20110288835
    Abstract: A data processing device includes a parameter estimation unit and a structure adjustment unit. The structure adjustment unit notes each state of an HMM as a noted state, obtains, for the noted state, a value corresponding to an eigen value difference which is a difference between a partial eigen value sum and a total eigen value sum, as a target degree value indicating a degree for selecting the noted state as a division target or a mergence target, selects a state having the target degree value larger than a division threshold value, as a division target, and selects a state having the target degree value smaller than a mergence threshold value, as a mergence target.
