The following two projects are to be presented on 6/18.

Group 8: Compare the approach proposed in "Variable Length Queries for
Time Series Data, ICDE'01" with the MultiPiece approach proposed in
"Fast Subsequence Matching in Time-series Databases, SIGMOD'94." After
partitioning the query into subqueries, should we do the search from the
shortest subquery or the longest subquery? why?

Group 9: Compare the Multi-Index approach we discussed in class for
range query processing with an approach employing R-tree to index the
feature points. Which approach will be better when the feature points
are clustered into groups?
