TLDR The goal is to find a principled way to classify data points with as large a margin as possible, ensuring better generalization ability for the algorithm.
Key insights
🎯
The perceptron algorithm converges with a finite number of mistakes, implying convergence, and there is a bound on the number of mistakes it makes.
🤯
The idea of having different W stars with varying margins for separating data sets introduces the concept of optimizing for the most effective separation.
📏
The number of mistakes made by the perceptron is inversely proportional to the size of the margin, meaning that a larger margin results in fewer mistakes.
💡
Instead of relying on perceptron, the question is whether we can directly find a w star that separates a linearly separable dataset with the largest possible margin.
🧠
The orange line with a larger margin is preferred over the blue line because it provides a better separator for the data set, even when there is noise or perturbations in the test data.
