Re: [Dclib-devel] Interrupting training

[Davis K. <dav...@us...>]

Thanks, I'm glad you like it :)

Sure, that should be easy to do.  Just add another templated argument to
the .train() method.  So something like this:
template <typename in, typename out, typename cancel_type>
return_type train(in,out, cancel_type canceler)
{
...
// somewhere inside the main loop
canceler(iteration_count);
...
}

Then you can pass in a function object that takes the current iteration and
every 100 or 1000 iterations checks the clock (or whatever you want to
check) and if it's been to long throws an exception.  Let me know which
trainers you do this to (or send me a patch file or whatever is convenient)
and I'll include the changes into the next dlib release, which should be
out in about 6 weeks or so.

Cheers,
Davis
