Logistic Regression (page 4 of 6)

The logistic regression machine learning algorithm uses a process of gradient descent (full, batch, or stochastic) to minimize the model's total cost function. Conceptualize gradient decsent as descending a mountain blindfolded or in with minimal visibility. The algorithm knows where to step next based on the steepness of the hill and the direction of the gradient, which are calculated using calculus.
