Thus, we can start with a random weight vector and subsequently follow the Note that the superscript \(i)" in the notation is simply an index into the training set, and has nothing to do with exponentiation. When we discuss prediction models, prediction errors can be decomposed into two main subcomponents we care about: error due to "bias" and error due to "variance".
