Implementing Gradient Descent for Logistic Regression - Atma's blog
Note: At this point, I realize my gradient descent is not really optimizing well. The equation of the decision boundary line is way off. Hence I approach to solve this problem using Scikit-Learn and see what its parameters are. Using the logistic regression from SKlearn, we fit the same data ...

"fitting the coefficients $\\theta$. This is done by computing the derivative of the loss function with respect to each coefficient $\\theta$. This gradient is an indication of how much the loss would vary if we change the coefficient.

GitHub - TheCodeHere/Logistic-Regression: Simple Logistic Regression code made from scratch in python 3.0, showing the gradient descent version and their respective version with and without regularization. The code will show, in each of the versions, the behaviour if the cost function and the approximation line obtained from the model at the end of the training. You can use an external dataset (e.g. "logReg_data.txt"). In this case, two-dimensional dataset were used.

Logistic Regression from Scratch in Python - nick becker
November 5, 2016 - Since the likelihood maximization in logistic regression doesn’t have a closed form solution, I’ll solve the optimization problem with gradient ascent. Gradient ascent is the same as gradient descent, except I’m maximizing instead of minimizing a function. Before I do any of that, though, I need some data. Like I did in my post on building neural networks from scratch...
