Davis King authored Apr 07, 2011

Modified the probabilistic() trainer adapter (and the train_probabilistic_decision_function() routine)
so that they work with objects which have an interface compatible with std::vector rather than strictly
just std::vector objects.  For example, random_subset_selector objects can be used (as was the case in
some previous versions of dlib).

It occurred to me that in some cases it is very easy to end up with dense vectors · 1e7659dc

Davis King authored Mar 22, 2011

which are slightly smaller than their corresponding sparse vectors.  So I changed
the requires clause of the dot(sparse,dense) and dot(dense,sparse) functions to not
require that the dense vector's size > sparse vector's size.  Now any combination
of sizes is legal.

This change is mainly about adding a result_type typedef to the various function objects. · aed73cd0

Davis King authored Mar 18, 2011

Prior to this change, different function objects declared their return type in different ways,
now this has all been reconciled.  Now they all declare it as a public typedef named result_type.

I also simplified the cross_validate_multiclass_trainer(), cross_validate_trainer(),
test_binary_decision_function(), and test_multiclass_decision_function().  They now always
return double matrices regardless of any other consideration.

Simplified the oca implementation slightly. It no longer keeps track of the · eef728d2

best point seen so far.  This change will allow me to use the optimizer in conjunction
with methods for quickly approximating subgradients and risk values without needing
to worry about the optimizer permanently fixating on what it erroneously thinks
is the best point.  Now the optimizer will just keep solving the cutting plane
subproblem and will use that solution as the current iterate and best known
solution.
