Consider a real-valued Gaussian process $ f$ on some compact domain $ \mathcal{X}$ with mean zero and covariance function $ k(x,x’) \in [0,1]$ (also known as the kernel function). This question concerns a finite collection of points in $ \mathcal{X}$ , namely, a set of sampled points $ \mathbf{x} = [x_1,\dotsc,x_n]^T$ and a query pointRead more

Given a multivariate polynomial and a maximum value for the exponent of any variable (which may not actually be attained by that polynomial), how can I best ‘vectorize’ the polynomial to a flat, dense 1-D array of coefficients, i.e. such that the array representing the zero polynomial has as many elements as the one inRead more
