a Schematic of hand written digit images recognition inference. The inset in a shows sample images of digits ‘0’, ‘3’, and ‘9’. b Confusion matrix on the test dataset. c Prediction accuracy and loss over 50 training iterations. The sample images shown in the inset of a are visualizations of data derived from the Optical Recognition of Handwritten Digits dataset29, in accordance with the Creative Commons Attribution 4.0 International License (CC BY 4.0; https://creativecommons.org/licenses/by/4.0/).
