  • Abstract
    An improved analysis for an information system is described in which the input and output alphabets consist of (equiprobable) ordered lists of m items, with two distortion criteria: 1) the fraction of item-pairs found out of order and 2) the fraction of items found in wrong positions. For the former it is shown that, as m \\rightarrow \\infty , the rate-distortion function R_{1} (D) is equivalent to mG(D) with, for small D , G(D)=\\log (2/D)-2+ O(D) . For the latter, R_{2} (D) = m \\log m(1 - D) + m(l - D)[\\log (1 - D) - 1] + o(m) .
