mvukad	695e33b25b	Fix missing format when writing Algorithm-based objects Added a writeFormat() method to Algorithm which must be called by the write() method of derived classes.	9 years ago
Eugene Khvedchenya	ee92a36123	Added parallel implementation of compute_gradient method.	9 years ago
Amro	542f2b2e3c	clean up code for train and predict methods of LR	9 years ago
Amro	e67178c696	fix LR predict with raw output in 2-class case In case of binary class, pred_m is initialized as zero vector and later returned when raw outputs are requested, but it is never filled.	9 years ago
Abe Friesen	9c6ff4d955	- LogisticRegressionImpl::predict() was changed to return the predicted value and to only write to the OutputArray results if specified (no longer segfaults). - Refactored batch and mini_batch training to use a common gradient computation function (removed duplicate code). - Altered the cost computation so that NAN is not computed unnecessarily. - Greatly simplified (and sped up) the code that appends a column of 1s to the data. - Minor code cleanup. Removed unused variables. Added cast to float to remove warning	9 years ago

Vadim Pisarevsky	052593c760	1. Input/OutputArray optimizations; 2. Algorithm::load/save added (moved from StatModel) 3. copyrights updated; added copyright/licensing info for ffmpeg 4. some warnings from Xcode 6.x are fixed	10 years ago
ippei ito	518fd59a10	fixed whitespace error	10 years ago
ippei ito	49b38fe793	Fixed compile error build with VisualStudio2013 on windows. REG_NONE defined in ml.hpp conflicts with defined in Winnt.h	10 years ago

Julien Nabet	2d5e3b57ea	Fix cppcheck reports warnings: (performance) Possible inefficient checking for 'lmap' emptiness (warning) Assignment of function parameter has no effect outside the function. Did you forget dereferencing it? (style) Array index '<xxx>' is used before limits check	10 years ago
