SPIDER The Spider Download
Downloading..
Download the latest version here . Just unzip into the directory of choice. Start MATLAB and run the script "use_spider" to startup.
If you use the Spider all the time, it would be a good idea to call "use_spider" in your startup.m file and to add the Spider root directory permanently to your MATLAB search path using, for example, PATHTOOL. A provided program "spider_init" attempts to do this but if your startup.m file is not in the usual place (in the matlab directory) then you have to do this manually.
Once installed, to get started type "help spider" and "help demos". E.g run spider/demos/microarray/go.m
Simple examples to start with...
Want to try something simple to start with on the command-line? Try these:
X=rand(50)-0.5; Y=sign(sum(X,2)); r=train(svm,data(X,Y))or use toy and toy2d , simple objects for generating toy datasets:
[r a]=train(svm('C=10'),toy2d); plot(a);
loss(train(svm,toy))
loss(train(cv(svm),toy))
get_mean(train(cv(svm),toy))
get_mean(train(cv(chain({l0 svm})),toy))
k=param(knn,'k',1:5); get_mean(train(cv(group({k gridsel(k) svm})),toy))
