This is a PyTorch model for classifying handwritten digits using a convolutional neural network. The model consists of two convolutional layers followed by two fully connected layers. The first convolutional layer has 20 filters of size 5x5 and takes in a grayscale image of size 28x28. The second convolutional layer has 50 filters of size 5x5. The output of the convolutional layers is passed through a max pooling layer with a kernel size of 2x2. The output of the max pooling layer is then flattened and passed through two fully connected layers with ReLU activation. The final output is a probability distribution over the 10 possible digit classes.
