6. An error calibration apparatus, comprising:
a memory, configured to store a program code; and
a processor, coupled to the memory, and configured to load and execute the program code to execute:
determining an error between an output value of at least one computing layer of a neural network and a corresponding corrected value, wherein a computation of the at least one computing layer is achieved by an analog circuit, and a machine learning accelerator achieves a computation by using the analog circuit; and
generating a calibration node according to the error, wherein the calibration node is located at a next layer of the at least one computing layer, the calibration node is used to minimize the error, and the calibration node is achieved by a digital circuit.
