Dimensionality reduction or feature extraction has been widely used in applications that require a set of data to be represented by a small set of variables. A linear projection is often chosen due to its computational attractiveness. The calculation of the linear basis that best explains the data is usually addressed using the Karhunen-Loeve Transform (KLT). Moreover, for applications where real-time performance and flexibility to accommodate new data are required, the linear projection is implemented in FPGAs due to their fine-grain parallelism and reconfigurability properties. Currently, the optimization of such a design in terms of area usage is considered as a separate problem to the basis calculation.
