More on that in the next section, where we’ll discuss the math behind the algorithm. A high learning rate can lead to “missing” the best parameter values, and a low learning rate can lead to slow optimization.

How much of an update there will be depends on one parameter - learning rate. This algorithm calculates the derivates with respect to each coefficient and updates them on each iteration. The best coefficients can be calculated through an iterative optimization process, known as gradient descent. Training multiple linear regression model means calculating the best coefficients for the line equation formula. Rescaled Inputs- use scalers or normalizer to make more reliable predictions.If that’s not the case, try using some transforms on your variables to make them more normal-looking Normal Distribution- the model will make more reliable predictions if your input and output variables are normally distributed.No Collinearity- model will overfit when you have highly correlated input variables.No Noise- model assumes that the input and output variables are not noisy - so remove outliers if possible.Linear Assumption- model assumes the relationship between variables is linear.The algorithm is rather strict on the requirements. What makes it different is the ability to handle multiple input features instead of just one. Multiple linear regression shares the same idea as its simple version - to find the best fitting line (hyperplane) given the input data. Introduction to Multiple Linear Regression You can download the corresponding notebook here. Introduction to Multiple Linear Regression.Today’s article is structured as follows: This is the second of many upcoming from scratch articles, so stay tuned to the blog if you want to learn more. Today you’ll get your hands dirty implementing multiple linear regression algorithm from scratch. How many? Well, that depends on how many input features there are - but more on that in a bit.

Multiple linear regression is similar to the simple linear regression covered last week - the only difference being multiple slope parameters. Linear regression is the simplest algorithm you’ll encounter while studying machine learning. Machine Learning can be easy and intuitive - here’s a complete from-scratch guide to Multiple Linear Regression
