Zusammenfassung: | To make it possible to analyze transition of a state to be analyzed in more detail.SOLUTION: An analysis device analyzes transition of a state on a time axis, and includes: a storage unit for storing a plurality of individual data that are observation data including attribute information and variations in a state; a model creation unit for dividing a state into a plurality of stages to create a transition model including a stage and transition of the stage; and a probability estimation unit for calculating prediction results regarding transition of the stage by using virtual data assuming attribute information and the transition model, setting a transition probability relative to the transition model based on the prediction results, comparing the set transition model and the transition probability with information on the individual data to estimate the transition probability of transition of the stage.SELECTED DRAWING: Figure 1
【課題】解析対象の状態の遷移をより詳細に解析することができる。【解決手段】時間軸上での状態の遷移を解析する解析装置であって、属性情報と状態の変動を含む観測データである複数の個別データと記憶する記憶部と、状態を複数のステージに分割し、ステージとステージの遷移とを含む遷移モデルを作成するモデル作成部と、属性情報を仮定した仮想データと遷移モデルを用いて、ステージの遷移に関する予測結果を算出し、予測結果に基づいて遷移モデルに対して遷移確率を設定し、設定した遷移モデル及び遷移確率と、個別データの情報とを比較して、ステージの遷移の遷移確率を推定する確率推定部と、を含む。【選択図】図1 |
