[comp.ai.neural-nets] Sequence Recognition

     Did anybody have any experience working on sequence
recognition? For instance, I want to check if a number string
contains the sequence '123' and these numbers need not to be in adjacent
like the following
        0001000220100300
        0100001020302000
but not this,
        2000100001003020
I need a networks which can give me 'true' to the first two
example and 'false' to the last one.
     I have two references:
 1. C.H. Sung and C.E. Priebe, "Temporal pattern recognition", in
    IJCNN, 1988.  (I could not understand this paper)
 2. Tank, Hopfield, "Neural computation by concentrating information
    in time", Proc. Natl. Acad. Sci., p.1896, 1987. (I think this one
    is too powerful for noise so that it will say 'true' for the last
    example.)
      I would appreciate any advice and suggestion.

Sincerely,
Ren-Jean
