No matter how efficient indexing-based Internet
search engines could be, indexing or inverse
representations of data, is not in the mainstream of
pattern recognition. One reason for a lack of interest
in indexing methods on the part of pattern
recognition community is instability of results due to
a use of noise-prone measurements as features,
rather than key words. The paper suggests a
multidimensional numerical data indexing method
that opens a path to accurate indexing-based pattern
recognition systems that inherit from their search
engines predecessors the ability to efficiently deal
with large amounts of data.
