WebJul 11, 2024 · In Linear regression, we draw a straight line (the best fit line) L1 such that the sum of distances of all the data points to the line is minimal. The equation of the line L1 is y=mx+c, where m is the slope and c is the y-intercept. We define a threshold T = 0.5, above which the output belongs to class 1 and class 0 otherwise. Image by Author
