Davis King 9043c7415e Added extract_ layer 2017-08-14 13:50:47 -04:00
Davis King 525cfc71af Added more tests for copy_tensor() 2017-08-14 12:48:37 -04:00
Davis King 7078cfaff5 Added an "add_to" option to tt:copy_tensor(). There was also a bug in the 
concat layer's backward() method.  It was assigning the gradient to previous
layers instead of adding the gradient, as required by the layer interface
specification.  This change also noticeably speeds up concat layers since only
one CUDA kernel launch now happens per concat operation, rather than one
kernel launch for each sample in a tensor.
 2017-08-14 12:28:26 -04:00
Davis King 89c9267e46 Made copy_tensor() use cudaMemcpyAsync() rather than cudaMemcpy(). 2017-08-14 09:52:53 -04:00

Davis King 0f2753b754 Changed how we print the network hash. 2017-08-06 08:54:10 -04:00
Davis King 7b26b2d1ff Made dnn_trainer print the network size when logged to an iostream. 2017-08-05 15:24:47 -04:00
Davis King 8b21c89efd Improved how the relaxed mmod overlap settings are determined. 2017-08-04 22:46:46 -04:00
Davis King ed683785ce Added get_synchronization_file() and get_test_one_step_calls() to dnn_trainer. 
Also added an operator<< for dnn_trainer that prints the parameters it's using.

These changes also break backwards compatibility with the previous
serialization format for dnn_trainer objects.
 2017-08-03 15:55:57 -04:00

Davis King 562d1b7519 Clarified spec 2017-08-03 09:36:51 -04:00
Davis King a1f94e167f Fixed spelling error in comment. 2017-08-03 09:14:36 -04:00
Davis King 29db3ee566 Added missing input validation to loss_mmod_. Specifically, the loss layer now 
checks if the user is giving truth boxes that can't be detected because the
non-max suppression settings would prevent them from being output at the same
time.  If this happens then we print a warning message and set one of the
offending boxes to "ignore".

libpng than they built against.
 2017-07-22 11:41:48 -04:00
Davis King 1f5335c1ad Made tensor_conv hold references to the cuda_data_void_ptr work buffers in the 
member area of the class.  This way, we avoid a potential error where the
buffers are reallocated while cuDNN is still using them in the background.
 2017-07-22 07:50:52 -04:00
Evgeniy Fominov 863702f059 cuDNN convolution algorithms shared workspace (#695) 
* added shared workspace

* rewrite shared workspace code

* rename and device-based buffer allocation

* fix cudnn_device_buffer constructors

Davis King e7fe423bc4 Added --sort and also the ability to propagate boxes from one image to the 
next using dlib::correlation_tracker.

Morosko 6525344fb8 Make http_client compile in C++11 and above (#714) 
* Make http_client compile in C++11 and above

* Optimize file reading

Juha Reunanen fc92774687 Add per-pixel mean square loss (#690) 
* Add per-pixel mean square loss

* Add documentation of loss_mean_squared_per_pixel_

* Add test case for per-pixel mean square loss: a simple autoencoder

* Review fix: reorder params of function tensor_index, so that the order corresponds to the convention used in the rest of the dlib code base

* Review fix: add breaks as intended, and change the rest of the test accordingly

* Again a case where the tests already work locally for me, but not on AppVeyor/Travis - this commit is a blindfolded attempt to fix the problem
(and it also fixes a compiler warning)
