Comments on 'Basis-restricted transformations and performance measures for spectral representations' by Pearl, J. |

Abstract: | In this correspondence, we comment on some of the shortcomings, for source encoding problems, of the measure of distance between orthonormal representations proposed by Pearl.^1We further examine, using rate-distortion theory, whether rates achievable for a given distortion level by the use of basis-restricted transformations have some inherent dissimilarity independently of input statistics and of other implied parameters. |
