It says a times x plus b makes y. In the context of machine learning, the input we provide would be x and the result of the equation, y, would be the output or the prediction if you will. The goal of machine learning is to find the a and b values that hold true for all the x and y pairs.

Web26 Feb 2024 · Sum of Squared Errors (SSE) The sum of squared errors is also called the residual sum of squares. It is defined as the variation of the dependent variable unexplained by the independent variable. SSE is given by the sum of the squared differences of the actual y-value \((Y_{i})\) and the predicted y-values \((\widehat{Y_{i}})\). Mathematically, Web22 Feb 2024 · Sum of Squares Error (SSE) – The sum of squared differences between predicted data points (ŷi) and observed data points (yi). SSE = Σ (ŷi – yi)2.
