pymc.gp.cov.ExpQuad#

class pymc.gp.cov.ExpQuad(input_dim, ls=None, ls_inv=None, active_dims=None)[source]#

The Exponentiated Quadratic kernel. Also referred to as the Squared Exponential, or Radial Basis Function kernel.

\[k(x, x') = \mathrm{exp}\left[ -\frac{(x - x')^2}{2 \ell^2} \right]\]

Methods
