JKernelMachines: A simple framework for Kernel Machines

JKernelMachines is a java library for learning with kernels. It is primary designed to deal with custom kernels that are not easily found in standard libraries, such as kernels on structured data.

  • Several learning algorithms (LaSVM, LaSVM-I, SMO, SimpleMKL, GradMKL, QNPKL, SGDQN, Pegasos, NystromSVM, LLSVM...)
  • Multiclass classification through generic classifiers.
  • Active learning
  • Datatype agnosticism through Java Generics
  • Easy coding of new kernels
  • Several standard and exotic kernels (kernel on bags, combination kernels, ...)
  • Input system (can read libsvm, csv, arff and fvec files)
  • Toys generator for artificial data
  • Basic linear algebra package (optionally based on EJML)
  • Evaluation and Cross Validation packages
  • Stand alone (requires only a working jdk 1.7 and ant for easy compiling)
  • Simple GUI



Available with the ant doc command, or here
