The constructors.
-.. ocv:function:: LogisticRegression::LogisticRegression( const LogisticRegressionParams& params)
+.. ocv:function:: LogisticRegression::LogisticRegression( const LogisticRegressionParams& params = LogisticRegressionParams())
:param params: The training parameters for the classifier of type ``LogisticRegressionParams``.
-------------------------------------
This function returns the trained paramters arranged across rows. For a two class classifcation problem, it returns a row matrix.
-.. ocv:function:: cv::Mat LogisticRegression::get_learnt_thetas() const
+.. ocv:function:: const cv::Mat LogisticRegression::get_learnt_thetas() const
It returns learnt paramters of the Logistic Regression as a matrix of type ``CV_32F``.
