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

Tian Zhi	f0434d60b0	fixed the type inconsistent with document. Document say probs will have CV_64F type. But in effect, it has CV_32F type. http://docs.opencv.org/3.0.0/d1/dfb/classcv_1_1ml_1_1EM.html#a2ea7da92a75bc7a7d665c241f547b9b9	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

Amro	13a0a37e63	fix randMVNormal in ML (#5469 ) Fix the failed assertion by replacing the GEMM call. Also random numbers are generated from normal distribution ~N(0,1), instead of uniform distribution ~U(0,1).	9 years ago

art-programmer	e0ef293645	Update em.cpp Fix a bug. When reading from a saved model, function decomposeCovs() will be called. And if covMatType is COV_MAT_DIAGONAL, covsEigenValues is computed using SVD and eigen values are sorted so that the order of eigen values is not preserved. This would lead to different result when calling function predict2.
