Similarity search for multidimensional data sequences
TLDR
We extend the traditional similarity search methods on time series data to support a multidimensional data sequence, such as a video stream. Expand

Dynamic Update Cube for Range-sum Queries
TLDR
We propose an efficient algorithm to reduce the update cost significantly while maintaining reasonable search efficiency, by using an index structure called the ∆ -tree. Expand

Space-efficient cubes for OLAP range-sum queries
TLDR
In this paper, we present a new cube representation called 'the PC Pool', which drastically reduces the space of the PC in a large data warehouse. Expand

Effective processing of continuous group-by aggregate queries in sensor networks
TLDR
We propose a framework, called the G-Framework, to effectively process continuous group-by aggregate queries in the environment where sensors are grouped by the geographical location. Expand

Representation and clustering of time series by means of segmentation based on PIPs detection
SAX is the representative time series representation method. SAX used the PAA technique to reduce the dimension of time series. But PAA technique has the demerit that cannot represent variousExpand

Selectivity Estimation for Optimizing Similarity Query in Multimedia Databases
TLDR
In this paper, we propose a curve fitting method using DCT to estimate the selectivity of a similarity query with a spherical shape in multimedia databases. Expand
