Book section · January 1, 2021 In this chapter, we introduce nonnegative matrix factorization and topic modeling. We will see that there is a natural structural assumption called separability that allows us to circumvent the worst-caseNP-hardness results for nonnegative matrix factoriza ... Full text Cite
