Some of them are based on quantisation error compensation, such as Error Spectrum Shaping, or finding a filter structure less affected by these errors--Low-Noise Design via State Space Optimisation (Douglas, 1987).
This is done by utilising the quantisation error [qi.
This means that a low quantisation error characterises a feature that is similar in all input vectors to the weight vector.
Quantisation error limits efficiency of AIM, therefore in designed measurement system AIM is combined with dithering.
