Default RBF - distance and weights


I have some questions about lecture 16 slides 3 and 6.

1. In slide 3, the distance is squared when included in the basis function of the hypothesis. This would bring down the significance of far away points even more, but what is the rationale behind the square?

2. In slide 6, you get the impression that each w_i is distributed. Is this correctly understood given each weight is solved for exactly? Or should it be that each \gamma_i is distributed?
