## Collaborative Filtering from Scratch with Python

Collaborative Filtering is a technique used in recommender systems to make predictions about the interests of a user by collecting preferences for many users. The underlying assumption of the collaborative filtering approach is that if

## Writing a Neural Network class in Python from scratch

Neural Networks Neural Network are computer systems inspired by the human brain, which can ‘learn things’ by looking at examples. They can be used in tasks like image recognition, where we want our model to

## Building a Logistic Regression in Python

Logistic Regression Logistic regression is a technique which can be applied to traditional statistics as well as machine learning. It is used to predict whether something is true or false and can be used to

## Linear Regression in Python (from scratch)

Linear Regression in Python In this post I wanted to show how to write from scratch a linear regression class in Python and then how to use it to make predictions. Let’s start! What is

## Implementing a simple Naive Bayes Classifier with Python

Naive Bayes Classifier The Naive Bayes classifier is a simple algorithm which allows us, by using the probabilities of each attribute within each class, to make predictions. It makes the strong assumption that the attributes
