Gradient Descent For Logistic Regression In R. Logistic function maps real values to 01. If func is strongly convex.
In the Logistic Regression algorithm the optimal parameters θ are found by minimising the following loss function. Jun 10 2018 The objective of gradient descent is to find out optimal parameters that result in optimising a given function. Oct 28 2011 Logistic Regression with Gradient Descent.
