It is changing our whole approach toward creativity, innovation, and problem-solving in the digital world. Let’s delve deeper to understand more about Generative AI through this ultimate Generative AI guide.

What is Generative AI?

In terms of functionality, Generative AI is a multimodal AI system that assists industries in reducing time spent on generating text, realistic images, and short videos; summarizing long texts, and helping in complex tasks like identifying defects in designs.

So, what is Generative AI?

Generative AI is an artificial intelligence system that uses deep learning models to generate content taking cues from the data it is trained on. The data can be in any form, such as images or human-readable text. The term Generative AI is coined as it can generate content – whether text, audio, or images. It performs such actions by detecting the underlying patterns of the input. The patterns act as a basis for creating similar content that is so realistic that it becomes very difficult to differentiate it from human-created works.

To make things much simpler, Generative AI is the creative side of AI that processes large sets of data and creates new content such as images, content, music, and more.

The Evolution of Generative AI

In the 1950s, when scientists introduced the concept of Machine Learning (ML) to the world, they were also toying with the idea of using Machine Learning to generate new data. Markov Chain is one of the first few examples of Generative AI which could be used to generate sequences of data based on the inputs. Unfortunately, the computational power and data resources didn’t support the learning activity in those days. Nevertheless, the technological developments and availability of digital data helped in thrusting the machine learning curve forward between the years 1990 – 2000.

  1. Technically, Generative AI was performing minimal functions, such as chatbot back in 1966.
  2. In the proceeding years, experts working on AI turned these simple chatbots into highly capable tools.
  3. After publishing the white paper “Attention is All You Need” in 2015, and performing thorough research for 4 years, in 2018, scientists introduced the concept of ‘Transformers.”
  4. Transformers replaced many old algorithms that were complex and were not able to generate superior quality output.
  5. OpenAI introduced ChatGPT in the year 2020 which uses GPT (Generative Pre-trained Transformer) models on neural networks using deep learning architecture to generate content.
  6. OpenAI brought another tool DALL-E in 2021 with the ability to generate realistic images based on the command prompts using text.
  7. A few eminent tech companies are racing to introduce Generative AI to new realms of work to reduce the burden on humans.

According to Statista, in the United States, the adoption rate of Generative AI in the workplace is the highest for Gen Z at 29%. Statistics prove that transformers are the reason for the drastic evolution of Generative AI.

How Does Generative AI Work?

Crafting the Formula for Creative AI!

Generative AI can learn the patterns and structures from the given data sets and then apply the knowledge in creating new data that is similar to the original dataset. Let’s get into understanding how this formula works.

Training Data

The initial training of Generative AI starts by sharing enormous amounts of datasets of the type of data that is required to be generated. For instance, if the Generative AI is intended to generate human face images, the datasets fed for training also consist of a large collection of human face images.

Model Architecture

In Generative AI, complex neural network architectures such as Generative Adversarial Networks (GANs) or Variational Autoencoders (VAEs) are used to learn the underlying patterns and features that are present in the given training data. These architectures boost the performance of the model.

Learning Patterns

As a next step in the training process, the model learns to identify patterns and correlations within the available datasets. For instance, Generative AI will learn to identify common facial features like eyes, nose, and mouth from the given human faces’ datasets.

Generating New Data

Once the training is completed, the Generative AI model produces new data samples based on the learned ones. By providing input data, we can test Generative AI by allowing it to produce similar output data. For example, the model takes the input data of given human faces and produces data that resembles the training dataset.

Refinement and Improvement

Once the output is produced, the Generative AI model undergoes a refinement process to enhance the output quality. The model may be fine-tuned by altering the parameters, refining the training process, or through techniques such as reinforcement learning to further improve the generated output.

Evaluation

The final stage is evaluation. Once the output is generated, its quality is checked using various metrics and assessment criteria. The model becomes successful when such generated output meets the desired criteria.

Thus, Generative AI uses cutting-edge AI techniques to understand the patterns of the given dataset and reproduce the same quality of output that resembles the originally fed datasets.

What are the Different Types of Generative AI Models?

To perform different functions perfectly, many techniques are used for Generative AI. As stated earlier, Generative AI uses neural networks, a type of architecture that functions and looks like a human brain. Deep learning also uses neural networks that contain more than three layers. So, let’s first understand the structure of neural networks.

Layers of interconnected nodes form a neural network where each node has an individual statistics model that processes a single facet of input based on its learning from the training data. It exactly functions like our brain where certain parts of the brain are dedicated to performing specific tasks. For instance, certain neurons might fire once we see a familiar face. In the same way, parts of neural networks also recognize different patterns and relationships based on the training data.

Individual nodes may recognize and provide individual decisions such as whether a word is a noun or not, the final output is caused by the domino effect when all these decisions come together as a complex output.

These neural networks are extensively used by data scientists to build a variety of Generative AI models. Let’s look at the most common architecture kinds.

Generative Adversarial Networks (GANs) and Variational Autoencoders (VAEs)

GAN and VAE are the two models used for image generation. The AI activity related to image generation started way back in the mid-2010s, thus giving us a glimpse of its capability in image generation in the present time. GANs function by one neural network generating an output, and the other one tries to analyze if it is fake or real. Through this kind of back-and-forth training, the model learns to create better images. Whereas the VAE generates encodings of the image parts and then creates sample parts of such encodings later decoding them to create new images.

Diffusion Models

In a diffusion model for generative AI, training data is destroyed via the addition of Gaussian noise and then recovered by reversing the addition of that noise. You can think of adding Gaussian noise as scrambling the pixels in the image. The noise is “Gaussian” because it’s added based on probabilities that lie along a bell curve. When the model reverses the noise, it makes predictions by decoding those probabilities, which results in an original image each time, even with the same prompt.

Large Language Models (LLMs)

With the advent of transformers, a new type of neural network, promising models of Generative AI such as LLM came into existence. Transformers can understand all the words of an input sentence in one go and find out how they are related, thus generating meaningful text. These transformers have been around since 2017 but training them with vast amounts of data and improving their performance helped to see a breakthrough in the form of today’s Generative AI natural language tools.

Hybrid models

In hybrid models, rule-based computation and machine learning along with neural networks are brought together to ensure human-like watchfulness of the AI system’s operations. Organizations can pick one of the above Generative AI models and attach rules-based or logic-based systems during or after their operations for performance enhancement or specific output.
