Libsvm以二进制格式保存模型文件 [英] Libsvm save model file in binary format

问题描述

我正在为libsvm训练一个巨大的数据文件，结果训练文件太大.有什么方法可以将libsvm库模型文件保存为二进制格式?

I am training a huge data file for libsvm and the resulting training file is too large. Is there any way to save the libsvm libraries model file in binary format?

推荐答案

如果您使用的是Matlab: 下载 svm_savemodel.c 和

If you are using Matlab: Download svm_savemodel.c and svm_model_matlab.c (this is already included in libsvm, you can try to use the original one, but if it doesn't work, try this link) to your libsvm dir. Compile the Mex file (mex svm_savemodel.c), then it should work:

%save model model

fid = fopen('model.bin','w');
model = fwrite(fid, model, 'int16');

%load('model.mat');

fid = fopen('model.bin','rb');
model = fread(fid, model, 'int16');

svm_savemodel(model,'model.model');

如果您使用的是C ++: 有一个将模型保存到文件的功能:

If you are using C++: There is a function that saves a model to a file:

int svm_save_model(const char *model_file_name, const struct svm_model *model);
