How does Netflix utilize linear algebra for movie recommendations?

• It uses derivatives to adjust user preferences.

• It uses vectors to represent preferences and matrices to compare them with other users' data.

• It applies filters to highlight features like edges or textures in movie posters.

• It calculates the slope of the error function to minimize mistakes.
