Updated: Sep 19, 2023


generative_ai

Introduction


Generative AI, aka Gen AI, is at the forefront of technological innovation, reshaping the way we perceive and interact with artificial intelligence (AI). It is a revolutionary field that makes use of the power of generative models to create content, including text, images, code, audio, and even videos.


In this article, we will explore what Gen AI is, its wide-ranging applications across different business functions and sectors, the different types of Gen AI, and its potential when integrated with two other fields of AI – Natural Language Processing (NLP) and Computer Vision.


Finally, we will show learning paths for developers, data scientists, and all AI enthusiasts following which they can master the science and art called Gen AI in the NLP and Computer Vision domains. These courses are developed by some of the leading Gen AI experts who have successfully implemented such projects across industries. These courses will equip you with the tools and knowledge to become a Specialist in this exciting and evolving field.


What is Gen AI?


Generative AI is an emerging sub-domain within the larger context of Artificial Intelligence. It focuses on creating smart systems that are capable of generating new content that could range from text to working code, and from images to audio, and video – all autonomously, with a little nudge (prompt) from the user!


These systems use generative models, such as Generative Adversarial Networks (GANs), Variational Autoencoders (VAEs), and Transformers, to generate data that closely resembles human-generated content.


Types of Gen AI



Gen AI encompasses various types of generative models and techniques. Some of the most prominent ones include:


Autoencoders


Imagine you have a magic box that can turn pictures of animals into secret codes and then turn those secret codes back into pictures of animals. Autoencoders are that magical box!


Here's how they work:

  • Encoding: First, you put a picture of an animal, like a cat, into the box. The magical box “looks” at the picture and generates a secret code representing all the important details about the cat, like its color, ears, tail, and fur.

  • Hiding the Picture: Then, the box hides the picture and keeps only the compressed secret code.

  • Decoding: Next when you try to reconstruct the cat’s picture, the magical box uses the secret code to bring back the cat picture. It's like finding the hidden cat picture and showing it to you again.

The cool thing is that sometimes the cat picture that comes back might look a little different from the one you put in. That's because the machine learned to make the secret code capture the most important things about cats, but not all of them. And, it tries to recreate the cat picture from those details only.


In short, Autoencoders are neural networks used for unsupervised learning and data compression. They can be adapted for generative tasks like image analysis, image denoising, dimensionality reduction, and can generate new data samples based on learned representations.


Sequence-to-Sequence (Seq2Seq) Models


These models generate sequences of data based on input sequences and are widely used for language translation, speech recognition, machine translation and text summarization. They power machine translation services like Google Translate and can create concise summaries of lengthy articles.


To better understand their working, imagine that Seq2Seq models are magical language machines. This machine can take in a sentence in one language, say English, and then transform it into another language's sentence, say French. It's like turning "Hello!" into "Bonjour!"


Here's how it works:

  • Input Sequence: You feed it a sequence of words, like "I love ice cream."

  • Magic Within: Within the machine, there's an artificial brain like structure (neural network) that understands languages. This brain processes your input sentence word by word to understand them.

  • Output Sequence: Then, it creates another sequence of words in a different language, and sends you the output as a chat response such as "J'adore la glace."

So, Seq2Seq models are magical because they can convert words from one language to another, help chatbots “talk” like humans, and can do other cool language tasks.


Variational Autoencoders (VAEs)


Imagine you have a magic machine that can turn your drawings of cats into super cool cat stickers. But you want your magic machine to not only make stickers but also make different types of stickers that look a bit different from each other.


A Variational Autoencoder (VAE) is like that magic machine for computers. It's a model that can take pictures or drawings and turn them into "codes" describing the pictures.

But here's the “Variation” comes in - VAEs are not boring and always give the same code for the same picture. They give you different codes that are similar to each other, but not exactly the same due to probabilistic or variational inference in the encoding process. This way, they can create different versions of your pictures, like making cats with different colors or patterns.


In a nutshell, VAEs are probabilistic generative models that focus on encoding and decoding data. They are often used for tasks like image generation and data compression. They have applications in creating high-quality images, generating realistic faces, and even in anomaly detection, where they can identify unusual patterns in data.


Variational Autoencoders (VAEs) are named thus because they are a variation of the traditional autoencoder architecture in neural networks. The term "autoencoder" itself refers to a neural network architecture that is designed to encode data into a lower-dimensional representation and then decode it back into its original form, effectively learning a compact representation or encoding of the data.


The "variational" part in VAEs comes from the use of probabilistic or variational inference in the encoding process. Unlike traditional autoencoders, which produce a fixed and deterministic encoding of input data, VAEs generate a probability distribution over possible encodings for a given input. This probabilistic approach allows VAEs to capture the uncertainty and variations in the data, making them well-suited for tasks like data generation and image synthesis.


Generative Adversarial Networks (GANs)


Imagine you have two friends: an artist and a detective. You want to create amazing pictures, but you're not an artist, and you also want to fool the detective with your pictures.


Here's how it works:

  • The Artist (Generator): This friend tries to create pictures from scratch. At first, their pictures might not look very good, but they keep practicing to make them better. They want to make pictures that look like real ones.

  • The Detective (Discriminator): Your detective friend's job is to look at the pictures and decide if they are real (made by a you, the human) or fake (made by the artist, the model). At first, the detective is not very good at telling real from fake.

  • The Challenge: Now, you have a game between your artist and detective friends. The artist keeps making pictures and tries to improve so that the detective can't tell which ones are fake. The detective gets better at spotting fakes as time goes on and they also get more practice.

  • Competition: This is where the magic happens. The artist and detective compete and get better and better. The artist tries to make pictures that are so good that even the detective can't tell they are fake. And the detective keeps getting better at spotting any mistakes in the pictures.

  • Outcome: After lots of rounds, you end up with pictures that are incredibly realistic, and your detective friend can hardly tell if they're fake or real.

So, a Generative Adversarial Network (GAN) is like this game where an artist (generator) and a detective (discriminator) compete to make and judge pictures. The result is that the artist becomes really good at making pictures that look real, and the detective gets really good at telling if they're fake. It's a clever way to create super-realistic images and even things like deep fake videos! They find applications in art generation, deepfake creation, and data augmentation for machine learning.


Transformers


Imagine you have a magic box that can understand and translate any language in the world. You show it a sentence, say in English, and it can tell you what it means in French, Spanish, or any other language you want.


Now, this magic box is called a "Transformer" - as it transforms the original input into something else. And it's not just limited to language translation - it can also help with other things like understanding stories, answering questions, and even drawing pictures.


The cool thing about Transformers is that they can learn by themselves. They are fed lots and lots of sentences and stories - from the internet - to become super smart. And as they can remember everything they have read, they can do their magic (transformations) really well.


In a nutshell, Transformers are super-smart bots that can understand languages, answer questions, and do many other tasks involving intelligence because they've learned a lot from reading and practicing. They also have applications in tasks requiring computer vision like image captioning. And as they can handle both sequential and non-sequential data, they are suitable for a wide range of generative tasks.


Recurrent Neural Networks (RNNs)


RNNs are a class of neural networks that can generate sequences of data. RNNs are valuable for sequential data generation, such as text prediction and generation, and speech synthesis. They are also used in chatbots, language modeling, music composition, and time series prediction.


To understand what RNNs do, imagine you're reading a story, and you want to enjoy the plot. To do so, you must be able to put every new word, phrase, and sentence in the larger context and understand their meaning in the story. You don't go about looking for the meaning of one word at a time. You remember the sentences you just read, and understand, create a context and use it to make sense of the current word within it. That's a bit like how Recurrent Neural Networks (RNNs) work.


RNNs are helper bots that can understand and process sequences of data, like words in a story or the steps in a recipe. They can keep track of what they've seen so far and when they see some new piece of information, they use their memory to understand it in the context of what came before.


In simple terms, RNNs help machine understand and make sense of things that happen one after the other, just like we do when we read a story or follow a recipe step by step. This ability makes RNNs great for tasks like understanding language, predicting the next word in a sentence, or even recognizing patterns in sequences, like in music or time-series data.


Variational Recurrent Autoencoders (VRAEs)


VRAEs combine the capabilities of VAEs and RNNs, making them suitable for generating sequences with continuous latent representations. They find use in sequence generation tasks, such as generating realistic handwriting or time series data.


To see you they work, imagine you have a magical machine that can turn stories into secret codes and then back into stories. Variational Recurrent Autoencoders (VRAEs) are a bit like that magical machine.


Here's how it works:

  • Story to Code: First, you give the machine a story. It turns that story into a secret code that only the machine understands.

  • Learning the Secrets: The machine learns how to make these secret codes by studying many stories. It tries to find patterns and common things in the stories and gets better as it reads and encodes more stories.

  • Code to Story: Later, when you want the story back, you give the machine the secret code. It then uses its knowledge to turn the code back into the original story.

  • Adding Magic: But here's the special part – the machine doesn't just give you the exact same story every time. It adds a little bit of magic (variation) to make the story different each time you ask for it. So, you might get a slightly different fairy tale, but it will still make sense.

So, VRAEs can take stories, turn them into secret codes, and then use those codes to generate new and slightly different stories. It makes them very important in developing applications like chatbots that mimic human service providers. Most humans can reproduce the exact same answer every time in a conversation - they will be slightly different each time. The chatbots add the variability in their responses to make conversations more interesting and lively - without losing the meaning or the context.


Markov Models


Markov models are used for generating sequences based on the probability of transitioning from one state to another. They are useful for generating sequences based on probabilistic transitions and are often used in text prediction and generation. They can be used to generate text that follows specific patterns or matches the style of someone popular like Shakespear.


To understand the concept better, imagine your little robot likes to play outside. It can play with a ball, sit down, and even jump. But, what this robot friend of yours decides to do next depends on what it did just before.


A Markov Model provides a rulebook for your robot’s outdoor adventures. Instead of thinking about all the things the robot could do, we focus on the things it's most likely to do based on what it did before.


For example, if it was playing with a ball, it might be more likely to keep playing with the ball or maybe jump up and down with excitement. But it's less likely to suddenly start sitting quietly.


Markov Models help us figure out the probabilities of a certain action that the robot might do next based on what it's been doing recently. This has application in many areas like daily weather forecasting or automated game play.


In effect, Markov Models are a set of rules helping us understand how something makes decisions by looking at what it did just before. It's a way to predict the future based on the recent past.


Gen AI for NLP - Specific Use Cases


Generative AI and Natural Language Processing form a powerful synergy to leverage and benefit from each other's capabilities. On one hand, Gen AI can harness NLP to enhance its understanding of human language and generate more contextually relevant and coherent text. On the other hand, by making use of Gen AI models, NLP researchers can generate better models that mimic human behavior more closely.


An expert who can leverage both, can converge their advantages to create intelligent systems/. Systems that can not only chat with human users, but also understand them, empathize with them, and generate responses that are the most appropriate for a given situation. This has the potential of revolutionizing many industries and business roles including customer service, content creation, mass media, and communication.


Here are some specific use cases:


1. Content Creation


Use Case: Text Generation for Content Production


When The Guardian published world’s first ever AI generated article in September 2020, it was considered a one-off event. But since the release of ChatGPT3 in November, 2022, the content generation process has improved by leaps and bounds. Today one can generate text in the style of any popular author, or mix the styles of some of your favorites as well.

As a developer, you need to understand different text generation techniques and their applications, such as creating automated content for websites or marketing materials. This will help you explore and develop NLP techniques for generating content suiting your specific needs, improving quality of content for content marketing.


2. Customer Support


Use Case: Chatbots with Human-Like Responses


Whether it is Bng or the ChatGPT’s premium chatbot, the kind of responses that they generate are simply mind-blowing. Do you wonder what wonders it could do to your customer support role, if you could just dump your entire knowledge and information base in one of these and they’ll be ready to answer anything that your visitors might ask.


Therefore understanding and mastering reinforcement learning for fine-tuning language models becomes imperative for enhancing customer support chatbots. This can lead to more fluid, conversational and context-aware chatbots - just like a human.


3. Financial Advisory


Use Case: Financial Text Summarization


Investing and personal finance is an integral part of many of our lives. But however we may try, it is very challenging to make sense of cryptic financial statements, annual reports, macroeconomic data, and in general any financial information.


With the help of fine-tuned language models trained on vast amounts of financial data and analysis, you can help your organization come up with great financial solutions that present information in an easy to understand manner for target audiences. There are NLP techniques that you can master for summarizing financial reports and news articles, aiding in investment decisions of bankers, financial advisors, and even lay investors.


4. Communication and Mass Media


Use case: Real-time news and information broadcasting


Gen AI, powered by NLP, can break down language barriers and facilitate global communication with help of its powerful features such as speech recognition, real-time translation in multiple languages, text-to-speech conversion, text summarization (for headlines), sentiment analysis for responding to crisis situations, and generating creative text for effective storytelling.


For example, speech recognition software and language translation systems aid the human interpreters at the United Nations (UN) - possibly the world’s largest gathering of multilingual communities. These systems convert the speech into text, and then translate it into the target language. The translation is then spoken aloud by a computerized voice or displayed on a screen for the audience to read.


Gen AI with Computer Vision - Application Areas


With the help of Generative Artificial Intelligence you can usher in innovations in leveraging Computer Vision in fields including image/video analysis and synthesis. Gen AI, through its advanced generative models, opens up new opportunities across various industries, ​​ revolutionizing many roles, offering improved accuracy, creativity, and efficiency in image, audio, and video analysis and synthesis.
