I’m trying to implement a RBF kernel for regression (similar to Kernel used in sklearn SVR). I want to capture non-linear relationships between the predictors and dependent variable. gamma = 1 with pm.Model() as model: x_i = pm.Normal("alpha", mu=0, sd=100, shape = X.shape[1]) w = pm.Normal…

I am no completely sure what is the implementation behind the kernel regression in sklearn, but I manage to make your example work: # bayesian rbf kernel with pm.Model() as model: # hyper-prior for ls ls = pm.Beta("ls", alpha=1e-2, beta=1e-4) cov_func = pm.gp.cov.ExpQuad(X.shape[1], ls=…

I have not seen it before, maybe different runs reach to different local minimals?
