Appeal No. 97-1622
Application No. 08/109,179
The claimed invention relates to an apparatus for
estimating the state of a system based on recorded historical
data which relate input and output data. Appellants disclose
on pages 12-16 of the specification that Figs. 1-4 illustrate
the quantization of data in an input space in accordance with
the required precision of output data, the development of a
causal relationship model based on the number of occurrences
of output data corresponding to particular combinations of
input data, and the calculation of areas of precision (i.e.
neighborhoods) in input space which correspond to output data
having the required precision. New input data is then placed
in the calculated neighborhood and the neighborhood is
enlarged or zoomed to extract similar case data based on the
degree of enlarging. Appellants also disclose on pages 30-35
of the specification various mathematical techniques for
determining the similarity of cases for extraction which are
then utilized to estimate system output state based on the new
input events. An application of the state estimating
apparatus to a heating/cooling system to estimate air
conditioning load is disclosed by appellants at page 17 of the
specification and illustrated at Figs. 5A and 5B.
