Explore linear regression as a simple, supervised machine learning method for predicting continuous targets using one or more input features, with salaries and car prices as examples.
Master simple linear regression with one input variable by finding the line of best fit that minimizes the distance to data points. Use the line equation y = m x + b to predict outputs, identify the intercept and slope from data, and assess relationships.
Install and use react-plotlyjs to plot study hours vs scores in a scatter graph, then explore fitting a regression line to predict exam scores.
Learn to compute R-squared as a regression evaluation using residuals. Ranges from 0 to 1, where 1 indicates perfect prediction, and shows how hours predict scores.
Compute the mean squared error to reproduce 9.5 mean squared error, then create a user interface with boxes for exam, car, and salary predictions using simple and multiple linear regression.
Learn how multiple linear regression extends simple regression by using two independent variables—study hours and sleep hours—to predict exam scores and fit a regression plane.
Organize matrices in code by building input X and output Y matrices in JavaScript for regression. Create an intercept column by mapping X rows and appending ones.
Learn to compute the adjugate of the x^T x matrix via cofactors and the determinant, then obtain the inverse for beta zero and coefficients of x1 and x2 in regression.
Train a multiple linear regression model using a dedicated package, format train inputs and outputs, and interpret the beta coefficients to see how age and experience affect salary.
Identify typos in car names by extracting unique values and verifying data categories. Create a fixed brands mapping and apply it during data cleaning to produce corrected, consistent car names.
Dive into the world of machine learning with Machine Learning with JS: Regression Tasks (Math + Code). This course offers a focused look at linear regression, blending theoretical knowledge with hands-on coding to teach you how to build and apply linear regression models using JavaScript.
What You Will Learn:
Core Principles of Linear Regression: Begin with the fundamentals of linear regression and expand into multiple regression techniques. Discover how these models can predict future outcomes based on past data.
Hands-On Coding: Engage directly with practical coding examples, utilizing JavaScript. You'll use Node.js for the computational aspects and React.js for dynamic data visualization.
