Until recently, NumPy in Python had simple, but useful financial functions. These NumPy Financial functions are extremely handy for many personal finance questions, like estimating how much interest you have to pay on a loan and how your money grows with a monthly investing plan with a certain interest rate. Recently, the financial functions are… Continue reading 5 Useful Personal Finance Functions from NumPy Financial

Image Reconstruction using Singular Value Decomposition (SVD) in Python
In this post, we will explore the use of SVD on Image analysis. We will mainly use SVD on images to get main components/singular vectors capturing the image and use part of them to reconstruct the image. Singular Value Decomposition (SVD) is one of the commonly used dimensionality reduction techniques. SVD/PCA is the mainstay of… Continue reading Image Reconstruction using Singular Value Decomposition (SVD) in Python
How To Discretize/Bin a Variable in Python with NumPy and Pandas?
Sometimes you may have a quantitative variable in your data set and you might want to discretize it or bin it or categorize it based on the values of the variable. For example, let us say you have measurements of height and want to discretize it such that it is 0 or 1 depending on… Continue reading How To Discretize/Bin a Variable in Python with NumPy and Pandas?
