Motivated by a neurophysiological experiment on prefrontal cortex, we study a scheme for learning abstract categories.
An abstract category represents a set of vectors that are identical to each other modulo substitution, e.g., 'ABAB', 'BABA', 'ACAC', etc.
The proposed method is a clustering-based unsupervised learning algorithm in which the recognition step is reduced to a maximum weight perfect matching problem.
Applying our method to real musical data, we confirmed that it properly acquired abstract categories of inputs.
Each learning unit represented a basic rhythm pattern or the rhythm pattern of a specific genre of music. |
