WebMar 5, 2024 · The reason is that both formulations describe a state about which we know nothing—we are in a state of total ignorance, the spins are completely random, all directions are equally likely. The density matrix describing such a state cannot depend on the direction we choose for our axes. WebApr 18, 2024 · 2.4.2.1 State Evolution. In order to precisely capture the dynamic property of the AMP algorithm, thereby facilitating the design of the denoiser η t,i (⋅), a state evolution formalism was first proposed in the paper . In this formalism, the MSE is a state variable and its variation from iteration to iteration can be represented by a plain ...
