Abstract
A method for hierarchical visualization of multi-dimensional data is provided. A first dimension-reduction process is applied to a multi-dimensional data set to obtain a first visualization. A subset of the multi-dimensional data set associated with a selected region of the dimension-reduced first visualization is selected. A second dimension-reduction process is applied to the selected subset of the multi-dimensional data set to obtain at least one additional visualization.
Claims30
A method for hierarchical visualization of multi-dimensional data, comprising:
- (a) applying a first dimension-reduction process to a multi-dimensional data set to obtain a first visualization;
- (b) selecting a subset of the multi-dimensional data set associated with a selected region of the dimension-reduced first visualization where more detail is desired;
- and
- (c) applying a second dimension-reduction process to the selected subset of the multi-dimensional data set to obtain at least one additional visualization.
A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform steps in a method for hierarchical visualization of multi-dimensional data, the method steps comprising:
- (a) applying a first dimension-reduction process to a multi-dimensional data set to obtain a first visualization;
- (b) selecting a subset of the multi-dimensional data set associated with a selected region of the dimension-reduced first visualization;
- and
- (c) applying a second dimension-reduction process to the selected subset of the multi-dimensional data set to obtain at least one additional visualization.
A computer system, comprising:
- a processor;
- and
- a program storage device readable by the computer system, tangibly embodying a program of instructions executable by the processor to perform steps in a method for hierarchical visualization of multi-dimensional data, the method steps comprising:
- applying a first dimension-reduction process to a multi-dimensional data set to obtain a first visualization;
- selecting a subset of the multi-dimensional data set associated with a selected region of the dimension-reduced first visualization;
- and
- applying a second dimension-reduction process to the selected subset of the multi-dimensional data set to obtain at least one additional visualization.
A computer data signal embodied in a transmission medium comprising:
- a first segment including dimension-reduction code to perform a dimension-reduction process to a multi-dimensional data set to obtain a first visualization;
- and
- a second segment including data selection code to select a subset of the multi-dimensional data set associated with a selected region of the dimension-reduced first visualization
- wherein the dimension-reduction code is applied at least one time to the selected subset of the multi-dimensional data set to obtain at least one additional visualization.
