Not the OP, but I've got some links for you:
1. https://en.wikipedia.org/wiki/Singular_value_decomposition#A...
of which the "Low-rank matrix approximation" is the most important one (it's like looking inside the matrix, seeing its significant components, and zeroing out the remaining ones to save space). See also PCA in statistics.

2. 1976 video about SVD https://www.youtube.com/watch?v=R9UoFyqJca8 that shows a visualization for an algorithm for how to compute it.
3. Good two-part blog post series https://jeremykun.com/2016/04/18/singular-value-decompositio... https://jeremykun.com/2016/05/16/singular-value-decompositio...
