Data Pre-Processing for Linear Regression in Machine Learning
Dec 13, 2023 · One of the most essential (and time-consuming!) parts of Linear Regression for Machine learning is the data pre-processing itself. This process ensures the data is ready to be trained to...
From Data Pre-processing to Optimizing a Regression Model Performance
Machine learning (ML) helps in finding complex and potentially useful patterns in data. These patterns are fed to a Machine Learning model that can then be used on new data points — a process called making predictions or performing inference. Building a Machine Learning model is a multistep process.
A review: Data pre-processing and data augmentation techniques
Jun 1, 2022 · To decrease the dependency on training data and to improve the performance of the machine learning model. This paper discusses flipping, rotating with slight degrees and others to augment the image data and shows how to perform data augmentation methods without distorting the original data. 1. Introduction.

Preprocessing Data for Linear Regression with Scikit-Learn
Aug 14, 2023 · In this blog, I’ll go over an example from one of FlatIron Bootcamp’s Data Science paired programming labs on how to do just that. The first step is to know what your model needs to predict. For this example with housing data, we will say it is SalePrice. Convention has it that y will be the target, and X will be the rest of the data.
