It is provided an analysis system comprising a processor executing a program and a memory storing the program. The analysis system further comprises a data mapping unit controlling the processor to set an attractive force and a repulsive force acting between the instances based on the similarity information between data, and arranging the instances in a vector space having a certain number of dimensions so that an energy caused by the attractive force and the repulsive force is less than a threshold defined in advance, and a clustering unit classifying the instances arranged in the vector space. The data mapping unit is configured to virtually add one dimension to the vector space, add a minute fluctuation to coordinates of the instances in a direction of the added dimension, and calculate a minimum number of dimensions of the vector space where the instances are stable with respect to the minute fluctuation. |
