What is Feature Engineering?

Feature engineering is a process of taking unrefined raw data and converting it into meaningful features that your model can understand better, and provide a better decision boundary. To give an example, think if you are a retailer, and you want to target your customers who you think will not do business...

Permutations and Combinations

Permutations When the order does matter it is called Permutation. In other words, a Permutation is an ordered Combination. We should really call this a "Permutation Lock"! There are basically two types of permutation: Repetition is Allowed: such as the lock above. It could be "00000". No Repetition:...

Simple Linear regression

Let’s take a look at this dataset. It’s related to the Co2 emission of different cars. It includes Engine size, Cylinders, Fuel Consumption and Co2 emissions for various car models. The question is: Given this dataset, can we predict the Co2 emission of a car, using another field, such as Engine...

Regression Models

The regression model is a powerful method that allows you to examine the relationship between two or more variables of interest. In other word, Regression models (both linear and non-linear) are used for predicting a real value, like salary for example. If your independent variable is time, then you...

Understanding Deep Learning with TensorFlow playground

The TensorFlow playground can be used to illustrate that deep learning uses multiple layers of abstraction. First, notice blue represents +1, orange represents -1, and white represents 0. Let’s start with the default classification example. There are 4 datasets. The four datasets: circular,...
