Create your Machine Learning library from scratch with R ! (1/3) - Enhance Data Science

When dealing with Machine Learning problems in R, most of the time you rely on already existing libraries. This fastens the analysis process, but do you really understand what is behind the algorithms? Could you implement a logistic regression from scratch with R? The goal of this post is to create our own basic machine learning library from scratch with R. We will only use the linear algebra tools available in R. The goal of liner regression is to estimate a continuous variable given a matrix of observations . Before dealing with the code, we need to derive the solution of the linear regression. Given a matrix of observations and the target .
