WebSuppose for the moment that there is a smooth function h: Rd×d → R such that h(W) = 0 if and only A(W) ∈ D. Then we can rewrite ( 1) as. min W ∈Rd×dQ(W;X)% subject toh(W) = 0. (2) As long as Q is smooth, this is a smooth, equality constrained program, for which a host of optimization schemes are available. WebOct 18, 2024 · This paper re-examines a continuous optimization framework dubbed NOTEARS for learning Bayesian networks. We first generalize existing algebraic characterizations of acyclicity to a class of matrix polynomials. Next, focusing on a one-parameter-per-edge setting, it is shown that the Karush-Kuhn-Tucker (KKT) optimality …
