Lower estimates for the mutual information involving single burials are consistently approached by predictions from the NBC and actually surpassed by predictions from the HMM. ...
Near-optimal prediction for the HMM is indicated by the agreement between its density of prediction information and the corresponding density of mutual information between input and output representations ...
This procedure was used by Crooks and Brenner (2004) to estimate the mutual information density between sequences of amino acid residues and corresponding sequences of secondary structure assignments ...
