Introduction to Generative AI (Gen AI)

Generative AI (Gen AI) refers to the class of artificial intelligence models that are designed to create new content—whether it’s images, text, audio, video, or other media—based on the input data they are trained on. Unlike traditional AI, which typically focuses on classification, prediction, or analysis, generative AI is focused on producing new data that mimics real-world input data.

In the past few years, the field of generative AI has gained significant attention due to its ability to create highly realistic and sophisticated content, leading to groundbreaking applications in various industries, including entertainment, business, and even scientific research. This tutorial explores the key concepts of generative AI, its tools, and its applications.

Core Concepts of Generative AI

1. Generative vs. Discriminative Models:
   • Discriminative Models: These models focus on identifying the boundary between different classes or predicting the output given an input. They are not designed to generate new data but to make predictions or classifications. Examples include logistic regression, decision trees, and support vector machines.
   • Generative Models: In contrast, generative models learn the distribution of data and can generate new data that follows the same distribution as the training set. Examples include generative adversarial networks (GANs), variational autoencoders (VAEs), and large language models (LLMs) like GPT.
2. Types of Generative Models:
   • Generative Adversarial Networks (GANs): GANs are a pair of models—a generator and a discriminator—that compete with each other. The generator creates data samples (such as images or audio), while the discriminator evaluates them, trying to distinguish between real and generated samples. Over time, the generator improves its ability to create data that is increasingly realistic, while the discriminator gets better at distinguishing the fakes.
   • Variational Autoencoders (VAEs): VAEs are a type of neural network that learns to encode input data into a compressed representation and then decode it back to the original data. They can also generate new data by sampling from the encoded space.
   • Transformers: Transformers, originally developed for natural language processing, have become the backbone of many generative AI models. They utilize self-attention mechanisms to process sequences of data, and models like GPT (Generative Pre-trained Transformer) and DALL·E are based on this architecture.
3. Training Generative Models:
   • The process of training generative models typically involves learning the underlying probability distribution of the input data, which can be images, text, or other forms of media. Training generative models requires large amounts of labeled data and substantial computational power, especially in the case of deep learning models.
4. Evaluation of Generative Models:
   • Evaluating the performance of generative models can be challenging because there is often no direct “correct” output, as there is in classification tasks. Common evaluation techniques include the use of human judgment, as well as quantitative metrics like Inception Score (IS), Fréchet Inception Distance (FID), and others that compare generated outputs to real-world data.
