Generative Adversarial Networks, or GANs, are a class of machine learning models that have gained significant attention in the field of AI research. They consist of two neural networks competing against each other: a generator and a discriminator. The generator tries to create data that is indistinguishable from real data, while the discriminator tries to distinguish between real and generated data.
Key Concepts
- Generator: This network generates new data instances that try to be as realistic as possible.
- Discriminator: This network evaluates the generated data and tries to classify it as real or fake.
- Training Process: The generator and discriminator are trained simultaneously in an adversarial manner. The generator improves by fooling the discriminator, and the discriminator improves by correctly identifying fake data.
Applications
GANs have been applied in various domains, including:
- Image Generation: Creating realistic images, such as portraits, landscapes, and abstract art.
- Video Generation: Generating videos with realistic motion and content.
- Text Generation: Producing coherent and contextually relevant text.
- Data Augmentation: Enhancing the diversity of training data for other machine learning models.
