WebDec 7, 2024 · It is known that block-wise convexity of the objective is not enough to guarantee convergence of BCD to the stationary points and some additional regularity condition is needed. In this work, we provide a simple modification of BCD that has guaranteed global convergence to the stationary points for block-wise convex objective … Webblock coordinate-wise Lipschitz continuity of ∇f(x) implies for i = 1,...,n f(x+Uivi) ≤ f(x)+h∇if(x),vii+ Li 2 kvik2 2, ∀x ∈ RN, vi ∈ RNi coordinate update obtained by minimizing …
