NettetLogistic Regression-Non Linear Decision Boundary Python · Coursera - Machine … Nettet7. jul. 2024 · Support vector machines are an improvement over maximal margin algorithms. Its biggest advantage is that it can define both a linear or a non-linear decision boundary by using kernel functions. This makes it more suitable for real-world problems, where data are not always completely separable with a straight line.
