The tutorial covers: NettetThe idea is to take our multidimensional linear model: y = a0 + a1x1 +a2x2 +a3x3 + ⋯. and build the x1,x2,x3, and so on, from our single-dimensional input x. That is, we let xn = fn(x), where fn() is some function that transforms our data. For example, if fn(x) = xn, our model becomes a polynomial regression: NettetOnce we fit a line to data, we find its equation and use that equation to make predictions.
