Struggling with Machine Learning algorithms? πŸ€–

Then you better stay with me! πŸ€“

We are going back to the basics to simplify ML algorithms.
... today's turn is Logistic Regression! πŸ‘‡πŸ»

It is a binary classification model used to classify our input data into two main categories.

It can be extended to multiple classifications... but today we'll focus on a binary one.

Also known as Simple Logistic Regression.

The Sigmoid Function is our mathematical wand, turning numbers into neat probabilities between 0 and 1.

It's what makes Logistic Regression tick, giving us a clear 'probabilistic' picture.

For every parametric ML algorithm, we need a LOSS FUNCTION.

It is our map to find our optimal solution or global minimum.

(hoping there is one! πŸ˜‰)

To obtain the sigmoid function, we can derive it from the Linear Regression equation.
