PROBLEM TO BE SOLVED: To provide a technique for detecting a behavior state with a sensor.SOLUTION: A teacher sequence acquisition unit 120 acquires teacher data sequences whose behavior states acquired by a sensor are known. A DTW (Dynamic Time Warping) method application unit 130 applies a DTW method to each of the teacher data sequences on the basis of inquiry sequences whose behavior states, indicated by each of the data sequences acquired by one or more sensors, is known. A feature vector acquisition unit 150 generates vectors having, as elements, ratios of the lengths of the teacher data sequences having matched the inquiry sequences to the lengths of the inquiry sequences. Among the vectors generated by the feature vector acquisition unit 150, a SVM (Support Vector Machine) learning unit 160 performs SVM learning that regards vectors, in which states of the inquiry sequences match states of the teacher data sequences, as one class and that regards vectors, in which the states of the inquiry sequences do not match the state of the teacher data sequences, as the other class, to generate a determiner. |
