Logistic Regression from ScratchIn Chapter 2, we developed a logistic regression model for binary classification with one neuron and applied it to two digits of the MNIST dataset. The actual Python code for the computational graph...doi:10.1007/978-1-4842-3790-8_10Michelucci, Umberto...

Welcome to your first (required) programming assignment! You will build a logistic regression classifier to recognize cats. This assignment will step you through how to do this with a Neural Network mindset, and so will also hone your intuitions about deep learning. ...
Why am I asking you to build a Logistic Regression from scratch? Here is a small survey which I did with professionals with 1-3 years of experience in analytics industry (my sample size is ~200). I was amazed to see such low percent of analyst who actually knows what goes behind the ...
Logistic RegressionLogistic Regression (contrary to its name) allows you to get binary (yes/no) answers from your data. Moreover, it gives you the probability for each answer. Questions like: Is this email spam? Should I ask my boss for a higher salary? Does this patient have diabetes?
So, what to do when we have a natural order in categories of dependent variables? In such a situation, Ordinal Regression comes to our rescue. What is Ordinal Logistic Regression? Ordinal Regression (also known as Ordinal Logistic Regression Python) is another extension of binomial logistics regr...

Logistic regression is another technique borrowed by machine learning from the field of statistics. It is the go-to method for binary classification problems (problems with two class values). In this post, you will discover the logistic regression algorithm for machine learning. After reading this ...
