What is Generative AI?
Generative AI refers to artificial intelligence systems that can create new content, including text, images, music, and code. Unlike traditional AI that focuses on analyzing and interpreting data, generative AI learns patterns from input data and uses these patterns to produce new, similar data.
Key Components
- Neural Networks: Complex systems of interconnected nodes that process information
- Training Data: The quality and quantity of training data significantly impact model performance
- Algorithms: Mathematical processes that guide the learning and generation process
- Latent Space: A compressed representation of data that captures essential features in a lower-dimensional space
Types of Generative Models
Several architectural approaches are commonly used in generative AI:
| Architecture Type | Common Uses | Notable Examples |
|---|---|---|
| Transformers | Text, Code | GPT, BERT |
| GANs | Images, Video | StyleGAN, CycleGAN |
| VAEs | Images, Music | MusicVAE |
| Diffusion Models | Images | Stable Diffusion |
Generative Adversarial Networks (GANs)
GANs consist of two neural networks: a generator and a discriminator. The generator creates new data instances, while the discriminator evaluates them. These networks are trained together to improve the quality of generated data over time. Learn more about GANs.
Variational Autoencoders (VAEs)
VAEs use an encoder-decoder architecture where the encoder compresses input data into a latent space, and the decoder reconstructs the data from this space. They excel at generating data with clear structure. Explore more about VAEs.
