As this uses the dual formulation, it also supports +arbitrary kernels. Correctness test, together with MATLAB reference code +are in /test. + +## Online GUI demo + +Can be found here: http://cs.stanford.edu/~karpathy/svmjs/demo/ + +Corresponding code is inside /demo directory. + +## Usage + +The simplest use case: +```javascript +// include the library + + +``` +Here, `data` and `testdata` are a 2D, NxD array of floats, `labels` and `testlabels` +is an array of size N that contains 1 or -1. You can also query for the raw margins: +```javascript +margins = svm.margins(testdata); +margin = svm.marginOne(testadata[0]); +``` + +The library supports arbitrary kernels, but currently comes with linear and rbf kernel: +```javascript +svm.train(data, labels, { kernel: function(v1,v2){ /* return K(v1, v2) */} }); // arbitrary function +svm.train(data, labels, { kernel: 'linear' }); +svm.train(data, labels, { kernel: 'rbf', rbfsigma: 0.5 }); // sigma in the gaussian kernel = 0.5 +``` + +For training you can pass in several options. Here are the defaults: +```javascript +var options = {}; +/* For C, Higher = you trust your data more. Lower = more regularization. +Should be in range of around 1e-2 ... 1e5 at most. */ +options.C = 1.0; +options.tol = 1e-4; // do not touch this unless you're pro +options.alphatol = 1e-7; // used for pruning non-support vectors. do not touch unless you're pro +options.maxiter = 10000; // if you have a larger problem, you may need to increase this +options.kernel = svmjs.linearKernel; // discussed above +options.numpasses = 10; // increase this for higher precision of the result. (but slower) +svm.train(data, labels, options); +``` + +Rules of thumb: You almost always want to try the linear SVM first and see how that works. You want +to play around with different values of C from about 1e-2 to 1e5, as every dataset is different. `C=1` +is usually a fairly reasonable value. Roughly, C is the cost to the SVM when it mis-classifies one of your +training examples. If you increase it, the SVM will try very hard to fit all your data, which may be good +if you strongly trust your data. In practice, you usually don't want it too high though. If linear kernel +doesn't work very well, try the rbf kernel. You will have to try different values of both C and just as crucially the sigma for the gaussian kernel. + +The linear SVM should be much faster than SVM with any other kernel. If you want it even faster +but less accurate, you want to play around with options.tol (try increase a bit). You can also try to +decrease options.maxiter and especially options.numpasses (decrease a bit). +If you use non-linear svm, you can also speed up the svm at test by playing around with +options.alphatol (try increase a bit). + +If you use linear or rbf kernel (instead of some custom one) you can load and save the svm: +```javascript +var svm = new svmjs.SVM(); +var json = svm.toJSON(); +var svm2 = new svmjs.SVM(); +svm2.fromJSON(json); +``` + +## Using in node +To use this library in [node.js](http://nodejs.org/), install with `npm`: + +``` +npm install svm +``` + +And use like so: + +```javascript +var svm = require("svm"); +var SVM = new svm.SVM(); +SVM.train(data, labels); +``` + +## Implementation details +The SMO algorithm is very space efficient, so you need not worry about +running out of space no matter how large your problem is. However, you do need to +worry about runtime efficiency. In practice, there are many heuristics one can +use to select the pair of alphas (i,j) to optimize and this uses a rather naive +approach. If you have a large and complex problem, you will need to increase +maxiter a lot.
