A variant of nonlinear blind source separation, the Nonlin-ear Dynamic Factor Analysis (NDFA) model, is based on noisy nonlinear mixtures of state variables, which are controlled by nonlinear system dynamics. The problem setting is blind because both the state variables, the nonlinear mixing model, and the nonlinear dynamics are unknown. As a special(More)
Introduction and motivation. This work presents results of electrical failure analysis and troubleshooting in an automotive ASIC. An unusual pattern of yield drop-out at sort test occurred suddenly on product which has been in manufacturing for years; no other products were affected by the problem. The pattern indicated strong wafer odd-even effect within a(More)
