Part 3: Create Python Code to implement a deep learning convolutional neural network for MNIST

Sure! Here is some sample Python code that you can use to implement a deep learning convolutional neural network (CNN) for the MNIST dataset:

import tensorflow as tf

# Load the MNIST dataset
(x_train, y_train), (x_test, y_test) = tf.keras.datasets.mnist.load_data()

# Normalize the input data
x_train = x_train / 255.0
x_test = x_test / 255.0

# Reshape the input data to (batch_size, height, width, channels)
x_train = x_train.reshape(-1, 28, 28, 1)
x_test = x_test.reshape(-1, 28, 28, 1)

# Convert the labels to one-hot encoding
y_train = tf.keras.utils.to_categorical(y_train)
y_test = tf.keras.utils.to_categorical(y_test)

# Build the model
model = tf.keras.Sequential()

# Add a convolutional layer
model.add(tf.keras.layers.Conv2D(32, kernel_size=(3, 3), activation='relu', input_shape=(28, 28, 1)))

# Add a max pooling layer
model.add(tf.keras.layers.MaxPooling2D(pool_size=(2, 2)))

# Add a dropout layer
model.add(tf.keras.layers.Dropout(0.25))

# Add a flatten layer
model.add(tf.keras.layers.Flatten())

# Add a dense layer
model.add(tf.keras.layers.Dense(128, activation='relu'))

# Add another dropout layer
model.add(tf.keras.layers.Dropout(0.5))

# Add the output layer
model.add(tf.keras.layers.Dense(10, activation='softmax'))

# Compile the model
model.compile(optimizer='adam', loss='categorical_crossentropy', metrics=['accuracy'])

# Train the model
model.fit(x_train, y_train, epochs=10, batch_size=128)

# Evaluate the model
score = model.evaluate(x_test, y_test, batch_size=128)
print('Test loss:', score[0])
print('Test accuracy:', score[1])

This code first loads the MNIST dataset, normalizes the input data, and converts the labels to one-hot encoding. It then builds a CNN model with several convolutional, max pooling, dropout, and dense layers. Finally, it trains the model on the training data and evaluates its performance on the test data.

You can customize the model architecture and training parameters to suit your needs. For example, you can try adding more convolutional layers or increasing the number of filters in each layer to see if it improves the model's performance.

Now, where are all the data scientists going to go?!
