  • Jan 24, 2017 · Principal Component Analysis is a dimensionality reduction technique that is often used to transform a high-dimensional dataset into a smaller-dimensional subspace. The details of the technique can be found here. In this example.
  • Introduction. Principal Component Analysis (PCA) is a linear dimensionality reduction technique that can be utilized for extracting information from a high-dimensional space by projecting it into a lower-dimensional sub-space. It tries to preserve the essential parts that have more variation of the data and remove the non-essential parts with fewer variation.

  • Mispointing of the solar dynamic (SD) concentrator designed for use on Space Station Freedom (SSF) causes the optical axis of the concentrator to be nonparallel to the incoming rays from the Sun. This causes solar flux not to be focused into the aperture hole of the receiver and may position the flux on other SSF components.
