Web19 feb. 2024 · while the update rule is. θ ( k + 1) = θ ( k) + η y t x t. which only occurs when there is a misclassification and we only care about the in the classification but. sign ( θ T x) = sign ( η θ T x) as long as η is positive. It only scales θ T x but our concern is just the sign, hence the learning rate is irrelevant.
