A complete example of applying the CNN model trained on MNIST to recognize handwritten digit pictures (pictures from the Internet)
1 Think about how to apply the training model How can the MNIST model trained through CNN be applied to recognize pictures of handwritten digits (pictures come from the Internet)? This problem bothered me for 2 days. Many of the codes I found online were to train the model and call the model in a […]
