Artificial Immune System-Based Music Genre Classification

We present a novel approach for the problem of automated music genre classification, which utilizes an Artificial Immune System (AIS)-based classifier. Our inspiration lies in the observation that the natural immune system has the intrinsic property of self/non-self cell discrimination, especially when the non-self (complementary) space of cells is significantly larger than the class of self cells. The AIS-based classifier that we have built is compared with KNN-, RBF- and SVM-based classifiers in various experiments involving music data. We find that the performance of our classifier is similar to that of the other classifiers when tested in multi-class (eg. four class) problems. On the other hand, it exceeds by a significant margin the performance of the other classifiers when tested in two class problems.
