Understanding Support Vector Machine Regression

Web20 mag 2024 · 8. Explain different types of kernel functions. A function is called kernel if there exist a function ϕ that maps a and b into another space such that K (a, b) = ϕ (a)T · ϕ (b). So you can use K as a kernel since you just know that a mapping ϕ exists, even if you don’t know what ϕ function is. WebSVM decision function h(z) = sign Xn i=1 y iα ik(x i,z) + b! Kernel SVM is like a smart nearest neighbor: it considers all training points but kernel function assigns more weight to closer points. It also learns a weight α i >0 for each training point and a bias b, and sets many α i = 0 for useless training points.
