By learning a latent representation that follows a specific probability distribution, VAEs enable generation of new data samples. We will delve into the concepts of VAEs, including the encoder-decoder structure and the role of the latent space in deep feature learning.

b. Generative Adversarial Networks (GANs): GANs are generative models that consist of two neural networks, a generator and a discriminator, which are trained in a competitive manner. The generator network learns to generate realistic data samples, while the discriminator network learns to distinguish between real and generated samples. GANs have achieved impressive results in image synthesis tasks.

c. Transfer Learning: Transfer learning is a technique that leverages pre-trained deep neural networks on large datasets and adapts them to new, smaller datasets or related tasks. By leveraging the knowledge and learned features from pre-training, transfer learning allows us to train deep feature learning models with limited labeled data, reducing training time and improving performance.
