Re: [Dclib-devel] Multiclass classification

[Mani A. <man...@gm...>]

Thanks! I also noticed there is a *one_vs_all* trainer 
(http://dlib.net/ml.html#one_vs_all_trainer)
Isn't it more efficient and faster than *one_vs_one* trainer for 
multiclass classification since it does not train N*(N-1)/2 binary 
classifiers.

Hi,

I am looking for a multiclass classification algorithm in Dlib that can 
classify inputs into three classes.

The inputs are 3-dimensional (x,y,z) and like the following picture. 
After the training phase, the algorithm

should be able to classify the input into class 1,2 or 3.

Can you please give me a hint or show me a skeleton example that I can 
start with?

Thanks!
