It is believed to be a very good learning material and reference for all the researchers and learners. The pdf of the English version is forbidden due to the copyright issues (Check the FAQ on the page to see more details). If you do not like reading online, the hardcopy is available on Amazon with a price of 72$ 😦 (I guess reading online is fine).
However, a translated pdf version in Chinese could be found and download on Github. I have to say that this translation speed is impressive. I have been reading this Chinese version and I can tell the quality is good enough for Chinese readers. Many thanks to the team for sharing the Deep Learning knowledge!
In linear algebra, the singular value decomposition (SVD) is a factorization of a real or complex matrix. If you want to ask the physical meaning of the singular value, then we must consider the actual application of SVD.
