Abstract: Weights of a neural network in a first number format are converted to a second number format. For at least a portion of the weights, a total quantisation error associated with quantising the weights to the second number format is computed in accordance with a first quantisation method. A subset of the weights to be quantised to the second number format is identified in accordance with a second quantisation method based on the total quantisation error. A set of quantised weights is generated by converting the weights to the second number format, wherein each weight in the subset is converted in accordance with the second quantisation method and each of the remaining weights is converted in accordance with the first quantisation method.
