What kind of novel dataset are we talking about?

Just from the top of my head, you could have encountered eigenvectors/eigenvalues:

- if you ever used spectral graph algorithms

- if you ever done dimensionality reduction via principal component analysis

- if you ever calculated the steady state distribution of a Markov chain

Image analysis and signal corrections on time series data. Extracting features from microscope images for example, correcting for signal convolutions.
