This post illustrates that practical convergence for separable data of PLA is achieved much faster than the theoretical estimate suggests

Here we compare Pocket PLA, Adaline and some of its variations with adjustable learning rate using artificial training data.

Adaptive linear neuron (or element) aka Adaline can be viewed as a variation of PLA with update scaled by the mismatch magnitude. While not the universally best choice for the classifier learning algorithm, Adaline can be viewed as an improvement over the original PLA.

This post discusses an outline of the the PLA convergence theorem. While the algorithm convergence is not obvious, its proof hinges only on two key inequalities.

Here we look at the Pocket algorithm that addresses an important practical issue of PLA stability and the absence of convergence for non-separable training dataset.
