Davis King 719dadc388 Added overloads of all the GUI event handlers so that now you can 
use general functions as callbacks (via any_function).  This way,
if you have a C++0x compiler, you can use lambda functions with the
event handlers.

Davis King e2bc112a7c Fixed a typo in the spec for the is_empty() functions. I also added an 
is_set() to the any_function so that it's interface is similar to the
member_function_pointer.

Davis King 3ad1facf9e Added an any_function which supports the same functionality as std::function from the 
upcoming C++0x standard.  I added this so dlib can be modified to easily support lambda
functions while still being compilable on compilers which don't support the new
std::function.

 2011-02-05 19:07:42 +00:00
Davis King 82fb3682fc Refactored the code in the reduced_decision_function_trainer2. Part of it has been turned into 
a global function called approximate_distance_function() which performs the main optimization.  The
reduced_decision_function_trainer2 now depends on this global function.  This changes makes this
function optimizer available for other purposes besides use in the reduced_decision_function_trainer2
object.

Davis King 543e289f72 Improved the distance_function object by turning it into a properly encapsulated class 
rather than just a simple struct.  I also added overloaded +, -, *, and / operators
for this object so you can do the kind of arithmetic you would expect on an object
which represents a point in a vector space.  This breaks backwards compatibility
with the previous interface though as the member variables are now private.

Davis King c547e7bcc5 Applied a patch from Nils Labugt which fixes a bug in the gui_core component (Bug ID: 3171720). 
The bug details are below:
    dlib GUI applications don't work anymore after I upgraded to Ubuntu 10.10 (AMD64). They
    consistently crash in base_window::set_title. XwcTextListToTextProperty returns
    XLocaleNotSupported instead of initializing 'property', but dlib ignores the return value,
    resulting in a crash in XLib when XSetWMName is called with garbage input or when
    property.value is XFreed without having been allocated.

Davis King 67f3f463cf Refactored the krr_trainer into two objects. A rr_trainer which just does 
linear ridge regression and the krr_trainer which uses the empirical_kernel_map
to do non-linear ridge regression.  No changes were made to the behavior of the
krr_trainer.  This update is just to allow the use of linear ridge regression
without a superfluous empirical_kernel_map running at the beginning of the training
process.

Davis King 81d2baa24b Removed the requirement that the lisf be non-empty when used to load an 
EKM.  Instead, the load() function now will accept non-empty lisf objects
and throw a non-fatal exception.  This behavior should be slightly less
surprising to users, especially since certain degenerate datasets can give
rise to empty lisf objects when you might not expect it.
