Generative AI models use various types of data to create new content, and understanding these types is crucial for their effectiveness.

Structured data is a key component, which includes organized and formatted data like tables, spreadsheets, and databases.

Unstructured data, on the other hand, includes text, images, and audio files that lack a predefined format.

Generative AI models can also use semi-structured data, which includes data with some level of organization, such as XML files.

Generative AI Models

Generative AI models are a type of artificial intelligence that can create a wide variety of data, including images, videos, audio, text, and 3D models. They work by learning patterns from existing data and using that knowledge to make predictions and generate new content.

There are several types of generative AI models, including Autoregressive Models, Flow-Based Models, and Generative Adversarial Networks (GANs). Autoregressive Models predict the next part of a sequence based on conditions from previous inputs, while Flow-Based Models learn the mapping between a simple distribution of data and the complex distribution present in real-world data. GANs, on the other hand, consist of a generator and a discriminator that work together to generate synthetic data that closely resembles real data.

Flow-based models learn the mapping between a simple distribution of data and the complex distribution present in real-world data.

These models use a series of invertible transformations, or flows, to map samples from the input distribution to samples from the target distribution.

A distribution of data refers to the way the values in a dataset are spread across the possible outcomes, capturing the underlying patterns and structures of data.

Flow-based models are especially powerful in image generation and density estimation, thanks to their ability to capture complex data distributions.

A key feature of flow-based models is that they apply a simple invertible transformation to the input data that can be easily reversed.

By starting from a simple initial distribution, such as random noise, and applying the transformation in reverse, the model can quickly generate new samples without requiring complex optimization.

Flow-based models can effectively capture complex data distributions, making them a valuable tool for tasks like image generation and density estimation.

They are also known for more stable training, which can save time and resources in the long run.

A flow-based generative model's strength is in its ability to calculate the exact likelihood of occurrence of a data point in its learned distribution.
