Flow Model + Lipschitz
Flow Model Check
Condition 1 — INVERTIBLE: Set y = f(x), solve for x. ONE answer → invertible ✅. TWO answers (±) → NOT invertible ❌
Condition 2 — DERIVATIVE EXISTS: Compute f'(x). If exists for all x → tractable ✅
Lipschitz Constant
K = maximum value of |f'(x)| If K ≤ 1 → 1-Lipschitz → can use in WGAN ✅ If K > 1 → cannot use in WGAN ❌
