Key Concepts in Generative Modeling: An Overview

Algorithms, at the heart of generative modelling, aim to understand and replicate the input data’s distribution. They engage in assessing underlying patterns or features of this data with the aim of generating outputs that resemble yet carry a uniqueness.

Key concepts include:

• Understanding the difference between generative and discriminative models,
• The role of latent spaces in capturing data characteristics 
• The importance of loss functions in guiding the learning process.

Types of Generative AI Models

• Variational Autoencoders (VAEs)

Variational autoencoders (VAEs) are prominently known for their ability to compress data into a compact representation, which can be used later to recreate fresh data points. This attribute is particularly useful in image generation and modification.

• Generative Adversarial Networks (GANs)

GANs consist of two competing networks – a generator that fabricates images and a discriminator that checks them. This rivalry facilitates the enhancement of generated images; thus, GANs emerge as potent tools for crafting realistic imagery and art.

• Auto-regressive Models

Based on previous elements, these models predict subsequent ones. Auto-regressive models play a pivotal role in generating clear and precise relevant text or music compositions.

• Flow-based Models

Designers create flow-based models for precise data reconstruction and modification, an ideal solution to tasks that necessitate detailed and accurate output, like image resolution enhancement.

• Transformer-based Model

Transformers, revolutionising language understanding and generation, empower models such as GPT – generative pre-trained transformer. They can produce text that mimics human writing with remarkable accuracy.
