Researchers have introduced the Z-Domain Neural Operator (ZNO), a novel causal neural operator designed for discrete-time dynamic systems. ZNO's architecture utilizes stable low-rank rational filters parameterized in the z-plane, addressing a gap in operator learning methods often focused on continuous-time problems. The model demonstrates particular effectiveness in system identification tasks involving stable rational systems with poles close to the unit circle and long memory dynamics. AI
