Learning a kernel function for classification with small training samples

Tomer Hertz, Aharon Bar Hillel, Daphna Weinshall
2006 Proceedings of the 23rd international conference on Machine learning - ICML '06  
We demonstrate performance enhancement on two challenging tasks: digit classification with kernel SVM, and facial image retrieval based on image similarity as measured by the learnt kernel.  ...  This kernel is also shown to enhance retrieval based on data similarity.  ...  These kernels can then be used for classification with kernel SVM. They can also be used directly for retrieval based on similarity (as measured by the kernel).  ...
