We now assume that there areC(P,N) dichotomies possible on them, and ask how many dichotomies are possible if another point (in general position) is added, i.e. rating distribution. As an example, consider the case of having to classify data into two classes. However, the book I'm using ("Machine learning with Python") suggests to use a small learning rate for convergence reason, without giving a proof.

The logistic loss is strictly convex and does not attain its infimum; consequently the solutions of logistic regression are in general off at infinity. The perceptron is a kind of binary classifier that maps its input $x$ (a real-valued vector in the simplest case) to an output value $f(x)$calculated as $f(x) = \langle w,x \rangle + b$ where $w$ is a vector of weights and $\langle \cdot,\cdot \rangle$ denotes dot product. endstream 0000008279 00000 n On convergence proofs on perceptrons.
