svm_learn svm_learn [options] example_file model_file で学習する。 example_fileは後で説明する書式に従って記述したテキストファイルで、model_fileは学習結果を収めるファイルでsvm_learnが作るものなので適当な名前を指定するだけで良い。 つまりmodel_fileを保存しておけば学習状態を独立して管理できる。 オプションに関しては基本的に-cオプションしか弄らないで良さそう。-cに渡す数値が大きくなるほどマージンを広くとるが学習に時間を要する。 ちなみに-zオプションは動作モードの選択で、分類、回帰、ランキングが選べる。 example_fileの書式 <target> <feature>:<value> <feature>:<value> ... <feature>:<value> # <info> <targ
SVM-perf: Support Vector Machine for Multivariate Performance Measures
SVMperf Support Vector Machine for Multivariate Performance Measures Author: Thorsten Joachims <thorsten@joachims.org> Cornell University Department of Computer Science Version: 3.00 Date: 07.09.2009 Overview SVMperf is an implementation of the Support Vector Machine (SVM) formulation for optimizing multivariate performance measures described in [Joachims, 2005]. Furthermore, SVMperf implements th
SVM-Multiclass: Multi-Class Support Vector Machine
SVMmulticlass Multi-Class Support Vector Machine Author: Thorsten Joachims <thorsten@joachims.org> Cornell University Department of Computer Science Version: 2.20 Date: 14.08.2008 Overview SVMmulticlass uses the multi-class formulation described in [1], but optimizes it with an algorithm that is very fast in the linear case. For a training set (x1,y1) ... (xn,yn) with labels yi in [1..k], it finds
