碩士 === 國立臺灣大學 === 農業工程學系 === 82 === The main purpose of this study is to present a theory of
learning called Nested Hyper-Rectangle Learning model (NHRL)
for streamflow estimation which plays an important role in
hydrology .The model''s structure has a simple format and easy
to extend and use . The NHRL algorithm simulates the way
humane learns by experiences for estimation and
classification . The learning is accomplished by storing
objects in Euclidean n-space , a points in the beginning .And
the exemplars are generalized to hyper-rectangles ,if the
examples "match" the exemplars.The hyper-rectangles may be
nested inside one another to arbitary depth . This model uses
"Similarity Metric" to measure the similarity between the new
example and exemplar , while the weight parameters in "
Similarity Metric " are adjusted dynamically,that is the
model has the ability of learning. Since the model was
generally employed for classification, this study tries to
modify the algorithm for estimation . The modified NHRL are
tested with two theoretical data functions which are generated
with Monte Carlo method ,and employs it in estimating the
streamflow of Taiwan''s rivers .Both the test and employment
results support the excellent ability of the modified NHRL in
estimation .
