New Fourier Representation Enables DNF Learning Under Complex Distributions

Researchers have developed a generalized Fourier representation to tackle the challenge of learning Disjunctive Normal Form (DNF) under non-product distributions. This new method represents any distribution as a Bayesian network, enabling adaptation of standard Fourier-based learning techniques. The work proves that the spectral norm of conjunctions remains bounded for certain Bayesian networks, generalizing previous findings and establishing the learnability of DNF and decision trees under these distributions.
