Data Reduction with Principal Component Analysis (PCA)¶
This step applies the Principal Component Analysis algorithm to search for orthogonal bases that best represent the data. Using these orthogonal bases, the original data can be projected onto a much smaller space. The size of the original data can be significantly reduced in this way.
- Normalized input data (large size)
- Reduced data set
