Visualization of Gaussian and Laplace noise
Gaussian probabilistic density function is log quadratic. Laplace probabilistic density function is log linear.
Procrustes Analysis
Despite differences in original position, size, and orientation, Data A and B should overlap very well if they have the same "shape".
