What is Generative AI?

Generative AI is also known as Gen AI in short. In easy terms, Gen AI is a kind of advanced AI that has the exceptional ability to create new content. It can also create images, videos, text, audio and more.

Complete History of Gen AI

Before explaining the work of gen AI, Let us first see an brief overview of the history of gen AI.

1947

One of the most famous mathematicians, Alan Turing, started working on artificial intelligence around 1941. In 1947, he talked about "intelligent machinery." In a paper named after him, Turing asked if a machine could think and act like a human.

1952

Generative AI is based on Machine Learning and deep learning algorithms.The first machine learning algorithm was developed by Arthur Samuel in 1952 for playing checkers – he also came up with the phrase "machine learning."

1957

In 1957, Frank Rosenblatt, a psychologist at Cornell University, created the first "neural network" called the Perceptron. It was like modern neural networks but had only one layer with adjustable settings between the input and output. This system didn't work well because it took too much time to train.

1960

In the 1960s, John McCarthy created the LISP programming language for artificial intelligence tasks. During the same decade, the first expert systems were developed to model human knowledge in specific areas. For example, Dendral was the first AI expert system designed to identify the molecular structure of unknown organic compounds.

Joseph Weizenbaum

1961

In the 1960s, Joseph Weizenbaum created one of the earliest examples of generative AI called the Eliza chatbot. Eliza used a rules-based approach, meaning it followed specific patterns to respond to users. However, it had many limitations. The chatbot had a limited vocabulary and couldn't understand context very well, making it easy for conversations to break down. Additionally, Eliza and other early chatbots were difficult to customize and expand, which made them less flexible and less useful for a variety of tasks. Despite these challenges, Eliza was an important step in the development of AI and chatbots.

1980

1980s: In the 1980s, generative AI was all about following rules. Computers used strict instructions to answer questions and solve problems. Expert systems, which focused on specific areas like medicine, were created. But these systems were limited—they couldn’t think outside the box or adapt to new situations.

1990

1990s: In the 1990s, AI started getting smarter! Researchers used statistical methods like Markov chains and Hidden Markov Models (HMMs) to improve tasks like text and speech generation. This made AI better at creating more natural-sounding results. Neural networks began to develop, setting the stage for bigger things.

2000

2000s (2000-2004): The 2000s were a game-changer! New deep learning models like Recurrent Neural Networks (RNNs) and Long Short-Term Memory networks (LSTMs) helped AI understand and create text and speech much more clearly. This made the generated content flow better, like having a real conversation!

2005

2005-2012: From 2005 to 2012, generative AI took huge leaps forward! The focus shifted to making neural networks even better, and AI began to generate more complex content.

2014

In 2014, Ian Goodfellow and his team introduced Generative Adversarial Networks (GANs), a major breakthrough in AI. GANs have two parts: a generator and a discriminator. The generator makes data, like images, and the discriminator checks if the data is real or fake. They compete, which helps the generator create more realistic data and the discriminator improve at spotting fakes. This process results in high-quality outputs. GANs have transformed areas like image creation, video generation, and art, becoming a key technology in generative AI.

2017

In 2017, a new AI model called the Transformer was introduced by Vaswani and his team. This model changed how AI handles language. Unlike older models, the Transformer doesn't process words one by one but looks at the whole sentence at once. This makes it faster and better at understanding context. It uses a method called "attention" to focus on important words, improving translation and text generation. The Transformer's design has led to powerful AI models like BERT and GPT, which can write essays, translate languages, and even chat with people, making it a major advancement in AI technology.

2020

2020: OpenAI released GPT-3, a groundbreaking language model. GPT-3 is one of the largest and most powerful models ever created. It can generate text that is coherent and relevant to the context, making it a major step forward in natural language generation.

2022

2022: OpenAI introduced DALL-E 2, a model that creates high-quality images from text descriptions. This model blends advances in natural language processing and computer vision, allowing it to generate detailed and realistic images based on the text it receives.

2023

2023: Generative AI continued to improve. Advances in models have enhanced text, image, and video generation. These improvements have expanded the possibilities of what generative AI can achieve, making it more powerful and versatile than ever before.

How does Gen AI work?

Generative AI models uses neural networks to understand the patterns and content from the provided data and then generates the new content based on that.Lets divide it into 5 sections to understand the process -

1. Data collection - The first step is to collect the data from various sources like social media platforms , books, articles, news.It also ensures that the collected data does not contains error and suitable for training.

2. Training the model - The collected data is then uses to train the generative model.It learns from the patterns and correlations of the data.And then it refines its abilities to content new content.

3. Tuning - A foundation model is like a generalist who knows a bit about many things but isn’t great at specific tasks. To make it better at creating the exact content you want, it needs to be fine-tuned or trained for that specific task. This can be done by providing more examples or adjusting its settings to improve its performance. This way, the model becomes more skilled in the specific area you're focusing on.

4. Fine Tuning - Fine-tuning is the process of taking a pre-trained model and making small adjustments to improve its performance for a specific task. It involves training the model on a smaller, task-specific dataset after it has already learned general patterns from a larger dataset. This helps the model specialize in generating outputs that are more accurate and relevant to the task, such as creating specific types of text, images, or other content. Fine-tuning essentially refines the model's knowledge to make it better suited for particular needs.

5. Evaluating model performance - Evaluating model performance is important after fine-tuning to make sure it works well for the task. This is done by checking how accurate the model is using metrics like accuracy, precision, and recall. For models that generate content, we might also look at the quality of the output through human feedback or visual checks. Testing the model with different types of data ensures it works well in real situations. This evaluation helps find any problems so the model can be improved before being used in the real world.

6. Deploying the model - Deploying the model involves integrating it into a real-world system where it can generate outputs for users. This process includes setting up the necessary infrastructure, creating user interfaces, and developing APIs for interaction. After deployment, the model’s performance is closely monitored to ensure it functions effectively and efficiently in live applications.

7. Monitoring and Checking - After deploying a generative AI model, it's important to keep checking and updating it. This includes monitoring its performance, spotting changes in data, retraining with new data, using user feedback to improve it, and making sure it stays secure and follows rules. This helps keep the model working well over time.
