Retrieval and Classification Methods
|
|
The goal of this project is to develop scalable classification methods
that can exploit the information available in large databases of
training data. Given an object to classify, one important problem is
how to correctly identify the most similar objects in the database.
An equally important problem is how to retrieve those objects
efficiently, despite having to search a very large space. Results of
this effort include algorithms for fast nearest neighbor retrieval
under computationally expensive distance measures, optimizing the
accuracy of nearest neighbor classifiers, and designing
query-sensitive distance measures that automatically identify, in
high-dimensional spaces, the dimensions that are the most informative
for each query object. |
