WebOct 9, 2024 · Linear Regression is associating any numerical (or binary, which is a particular numerical) value to a coefficient. Multiplying those values by those coefficients gives you an output, and setting the threshold, you know if the model predicts 1 or 0. (This is a brief summary, you'll find plenty of people explaining in details how it works). WebAug 27, 2024 · It is possible to constrain to linear regression in scikit-learn to only positive coefficients. The sklearn.linear_model.LinearRegression has an option for positive=True which: When set to True, forces the coefficients to be positive. This option is only supported for dense arrays.
