Abstract
A system includes an input for accepting a dataset including at least two sets of data in a dataset domain and one or more processors configured to derive at least two principal components from the dataset using principal component analysis, the at least two principal components being orthogonal to one another, map the dataset to a principal component domain derived from the at least two principal components, generate additional data in the principal component domain, and remap the additional data in the principal component domain back to the dataset domain as a newly generated dataset. Methods of operation and description of storage media, the operation of which performs the above operations, are also described.

A system, comprising:
- an input for accepting a dataset including at least two sets of data in a dataset domain;
- and
- one or more processors configured to:
- derive at least two principal components from the dataset using principal component analysis, the at least two principal components being orthogonal to one another,
- map the dataset to a principal component domain derived from the at least two principal components,
- generate additional data in the principal component domain, and
- remap the additional data in the principal component domain back to the dataset domain as a newly generated dataset.
A method, comprising:
- accepting a dataset including at least two sets of data in a dataset domain;
- deriving at least two principal components from the dataset using principal component analysis, the at least two principal components being orthogonal to one another;
- mapping the dataset to a principal component domain derived from the at least two principal components;
- generating additional data in the principal component domain;
- and
- remapping the additional data in the principal component domain back to the dataset domain as a newly generated dataset.
A non-transitory computer-readable storage medium storing one or more instructions, which, when executed by one or more processors of a computing device, cause the computing device to:
- accept a dataset including at least two sets of data in a dataset domain;
- derive at least two principal components from the dataset using principal component analysis, the at least two principal components being orthogonal to one another;
- map the dataset to a principal component domain derived from the at least two principal components;
- generate additional data in the principal component domain;
- and
- remap the additional data in the principal component domain back to the dataset domain as a newly generated dataset.
