  1. Deep learning in Python is typically implemented using frameworks like TensorFlow, Keras, or PyTorch, which provide high-level APIs for building and training neural networks efficiently. Below is a simple example of an image classification model using Keras with TensorFlow backend.

    Steps to Build a Basic Deep Learning Model

    1. Import Required Libraries

    import tensorflow as tf
    from tensorflow import keras
    from tensorflow.keras import layers

    2. Load and Prepare Dataset Here we use the MNIST dataset for handwritten digit recognition.

    (x_train, y_train), (x_test, y_test) = keras.datasets.mnist.load_data()
    x_train = x_train.astype("float32") / 255.0
    x_test = x_test.astype("float32") / 255.0
    Copied!

    3. Define the Model Architecture

    model = keras.Sequential([
    layers.Flatten(input_shape=(28, 28)),
    layers.Dense(128, activation='relu'),
    layers.Dropout(0.2),
    layers.Dense(10, activation='softmax')
    ])
    Copied!

    4. Compile the Model

    model.compile(optimizer='adam',
    loss='sparse_categorical_crossentropy',
    metrics=['accuracy'])
    Copied!
