Module 1: What is Generative AI?

1.1 Introduction to Generative AI

Definition and Overview:

Generative AI refers to a subset of artificial intelligence that focuses on creating new data samples that resemble a given dataset. Unlike traditional AI models that classify or predict, generative models generate new, synthetic data such as text, images, or audio.

History and Evolution of Generative AI:

Generative AI has evolved from basic statistical models to advanced neural networkbased approaches. Early methods like Markov chains and Hidden Markov Models (HMMs) laid the groundwork. The introduction of neural networks, especially GANs (Generative Adversarial Networks) and VAEs (Variational Autoencoders), revolutionized generative capabilities in the mid2010s.

Comparison with Discriminative Models:

Discriminative models, like logistic regression or SVMs, focus on predicting labels or classes for given data. Generative models, on the other hand, model the distribution of the data to generate new samples. They aim to understand how data is distributed, allowing them to create new instances similar to the training data.
