WebHere are the most common kernels: Linear: k ( x, z) = x ⊤ z. RBF: k ( x, z) = e − ( x − z) 2 σ 2. Polynomial: k ( x, z) = ( 1 + x ⊤ z) d. Kernels built by recursively combining one or more of the following rules are called well-defined kernels : k ( x, z) = x ⊤ z. k ( x, z) = c k 1 ( x, z) Webnel, the variance of additive noise, and the RBF bandwidth, respectively. In practice, a maximum a posteriori (MAP) probability estimation is used to learn the latent space X. …
