For locally weighted linear regression we will instead do the following: Fit θ to minimize ∑ i = 1 m w ( i) ( ( i) y − θ T x ( i)) 2. Output θ T x. A fairly standard choice for the weights is the following bell shaped function: w ( i) = exp ( − ( x ( i) − x) 2 2 τ 2) Note that this is just a bell shaped curve, not a ... high cliff biome location breakpoint
