(18) We report that, through the use of alternative encodings of the DNA sequence in the complex plane, the number of FFTs performed can be traded off against (i) signal-to-noise ratio, and (ii) a certain degree of filtering for local similarity via k-tuple correlation.
(19) We defined as rare those 5-tuples having an observed frequency less than 50% of that expected by chance on the basis of base composition, and which had a reduction in frequency not attributable to CpG suppression or to coding constraints.
(20) Nucleotide or amino-acid sequences are interpreted as successions of words of length k (k-tuples) the frequencies of which are highly variable in different statistical populations of genes or proteins.
Vector
Definition:
