摘要： Even if data includes a defect or an outlier in features thereof, the influence of the defect or the outlier of the features is suppressed to perform a highly precise abnormality detection, and data including high-dimensional features is processable to accomplish the highly stable detection of an abnormality. The abnormality detection system which detects abnormal data in a data sequence including data of multi-dimensional features, and the system includes storing or generating a generation distribution of features of the data and reference data indicative of normal data; obtaining, every piece of the data sequence, a probability that when features are virtually generated from the generation distribution, the features are nearer to the reference data than the features of each piece of the data; and taking the probability as a one-dimensional dissimilarity degree between each piece of the data and the reference data, thereby determining abnormal data.

摘要： A problem to be solved is to provide a pattern matching system and the like which can match patterns including time change with high accuracy and safety. The problem can be solved by a pattern matching system which includes a template storage unit, a feature extraction unit, and a matching unit. The template pattern stores a template pattern. The feature extraction unit extracts features of an input pattern. The matching unit performs a first matching in which a first feature not changing with time among the features of the input pattern is matched with the template pattern and performs a second matching other than the first matching, in which a second feature changing with time among the features of the input pattern is matched with the template pattern.
