Linear Regression in Python with Scikit-Learn

There are two types of supervised machine learning algorithms: Regression and classification. The former predicts continuous value outputs while the latter predicts discrete outputs. For instance, predicting the price of a house in dollars is a regression problem whereas predicting whether a tumor is malignant

K-Nearest Neighbors Algorithm in Python and Scikit-Learn

The K-nearest neighbors (KNN) algorithm is a type of supervised machine learning algorithms. KNN is extremely easy to implement in its most basic form, and yet performs quite complex classification tasks. It is a lazy learning algorithm since it doesn’t have a specialized training phase.

Python Metaclasses and Metaprogramming

Imagine if you could have computer programs that wrote your code for you. It is possible, but the machines will not write all your code for you! This technique, called metaprogramming, is popular with code framework developers. This is how you get code generation and

Reading Files with Python

To work with stored data, file handling belongs to the core knowledge of every professional Python programmer. Right from its earliest release, both reading and writing data to files are built-in Python features. In comparison to other programming languages like C or Java it is

Decision Trees in Python with Scikit-Learn

Introduction A decision tree is one of most frequently and widely used supervised machine learning algorithms that can perform both regression and classification tasks. The intuition behind the decision tree algorithm is simple, yet also very powerful. For each attribute in the dataset, the decision

Creating and Deleting Directories with Python

This article continues with our series on interacting with the file system in Python. The previous articles dealt with reading and writing files. Interestingly, the file system is much more than a way to store/retrieve data to disk. There are also various other types of
