Davis King 1aa6667481 Switched this example to use the svm C instead of nu trainer. 2017-11-25 08:26:16 -05:00
Davis King 0e7e433096 Minor changes to avoid compiler warnings. 2017-11-25 08:07:36 -05:00
Davis King f3ecb81f5e Changed default solver epsilon so that it will solve to full floating point 
precision by default.  If the user is OK with less precision they can change
it.

Davis King 2ad9cd7843 Fixing code for visual studio 2017-11-25 07:42:48 -05:00
Davis King 04991b7da6 Made this example program use the new find_max_global() instead of grid search 
and BOBYQA.  This greatly simplifies the example.

Davis King fc6cce9f89 Made find_max_global() automatically apply a log-scale transform to variables 
that obviously need it.

Davis King 9a8f312127 Made the loss dumping between learning rate changes a little more relaxed. In 
particular, rather than just dumping exactly 400 of the last loss values, it
now dumps 400 + 10% of the loss buffer.  This way, the amount of the dump is
proportional to the steps without progress threshold.  This is better because
when the user sets the steps without progress to something larger it probably
means you need to look at more loss values to determine that we should stop,
so dumping more in that case ought to be better.

Juha Reunanen c0b7bf9e6c Problem: log loss may become infinite, if g[idx] goes zero (#938) 
* Problem: log loss may become infinite, if g[idx] goes zero
Solution: limit the input of the log function to 1e-6 (or more)

* Parameterize the safe_log epsilon limit, and make the default value 1e-10

Davis King 532e2a3e61 Made the global_function_search object use the faster incremental 
upper_bound_function::add().  Also fixed some issues in the solver.

Davis King 5529ddfb82 Added a .add() to upper_bound_function so that the upper bound can be quickly 
updated without needing to resolve the whole QP.

Davis King f1fe908a9d Added loss_dot layer 2017-11-17 19:07:41 -05:00
Davis King a02208018b Upgraded the con_ layer so that you can set the nr or nc to 0 in the layer 
specification and this means "make the filter cover the whole input image
dimension".  So it's just an easy way to make a filter sized exactly so that it
will have one output along that dimension.

Kino 364e97c159 generic_image all the way (#921) 
* generic_image all the way

tried to hunt down and correct the functions that were using a
non-generic_image approach to dlib’s generic images.

* generic image fix fix

Had to change a couple of const_image_view to non-const versions so array access is possible in the rest of the code

* same

same

* back to sanity
