| SHOGUN - is a new machine learning toolbox with focus on large |
| scale kernel methods and especially on Support Vector Machines |
| (SVM) with focus to bioinformatics. It provides a generic SVM |
| object interfacing to several different SVM implementations. Each |
| of the SVMs can be combined with a variety of the many kernels |
| implemented. It can deal with weighted linear combination of a |
| number of sub-kernels, each of which not necessarily working on the |
| same domain, where an optimal sub-kernel weighting can be learned |
| using Multiple Kernel Learning. Apart from SVM 2-class |
| classification and regression problems, a number of linear methods |
| like Linear Discriminant Analysis (LDA), Linear Programming Machine |
| (LPM), (Kernel) Perceptrons and also algorithms to train hidden |
| markov models are implemented. The input feature-objects can be |
| dense, sparse or strings and of type int/short/double/char and can |
| be converted into different feature types. Chains of preprocessors |
| (e.g. substracting the mean) can be attached to each feature object |
| allowing for on-the-fly pre-processing. |
