What is Generative AI: Exploring Examples, Use Cases, and Models

Generative AI refers to artificial intelligence systems that have the capability to generate new content (text, images, audio, synthetic data) using the data on which they were trained.  The output generated by these AI systems could include poetry, a physics explanation, a video, or even new music.

After the release of ChatGPT, the hype around generative AI is rapidly growing. The technology made it onto Gartner’s 2023 Emerging Technologies and Trends Impact Radar, recognized as a highly influential and swiftly advancing technology set to revolutionize productivity. What has made generative AI so popular in recent times is the fact that people can now use natural language prompts to interact with AI. This has led to a variety of applications across industries where AI generators assist with tasks such as writing, research, coding, and design.

Benefits of generative AI

• Improved decision-making: Generative AI models can provide insights and predictions based on data analysis, helping businesses make more informed decisions. Based on the survey of generative ai almost 85% of leaders regularly incorporate generative AI into their work.
• Innovation: Businesses can generate ideas for new products and processes using generative AI. These practices foster innovation and help teams stay ahead of the curve.
• Personalization: Generative AI models can be trained on individual user data to facilitate personalized customer experiences.
• Accelerated TAT- Generative AI helps generate new data faster, improving turnaround time for your projects. This is also helpful in improving business agility and adapting to changing customer demands.

Limitations of generative AI

• Resource intensive: Training a generative AI model is an extremely complex process requiring much time and resources. Even then, ensuring high accuracy in its output is not easy.
• Slower responses-Generative AI can have higher latency due to the massive scale of operations. This means slower responses in real-time interactive apps like chatbots or AI voice assistants.
• Unreliable results: Generative AI relies on high-quality data to make accurate predictions. So incomplete, inaccurate, or outdated data can lead to unreliable results.
• Security argument- Many organizations have argued on using user data to train AI models. There are concerns regarding the security of user data, privacy, and accessibility.
• Bias and ethical concerns: If the training data contains bias or prejudice, generative AI models can perpetuate those biases in their output.Plus, using generative AI models for creating fake content raises ethical concerns about the potential for misinformation and manipulation.

Generative AI has its origins in neural networks. Neural networks, inspired by the biological neural networks in human brains, are composed of interconnected nodes that transmit signals between each other. By adjusting the connections between nodes, neural networks are able to “learn” to perform tasks simply from exposure to examples.

The 1980s and 1990s saw incremental expansion of neural networks. Recurrent neural networks (RNNs) emerged, capable of learning sequences and patterns in data. By 1997, neural networks had significantly advanced – successfully generating handwritten digits 0-9, though language and creative capabilities remained a challenge.

A major breakthrough came in 2017 with the invention of the Transformer architecture. Unlike previous neural networks, transformers process an entire sequence of data at once, allowing much greater context and coherence. In 2018, OpenAI built on transformers to create GPT-1 and GPT-2 – language models finally capable of paragraph-length text generation.

Then 2020 brought the commercial release of GPT-3 by OpenAI, the most powerful transformer-based language model yet. Soon, Google’s Bard and Anthropic’s Claude became popular generative AI examples too, followed by a range of generative AI chatbots. Since 2020, the pace of evolution in generative AI continues rapidly – with models incorporating ever more data in pursuit of more sophisticated, trustworthy, and safe generative capabilities.

Generative AI models work by learning the patterns in a dataset and then using that knowledge to create new content similar to the original data. These models are ‘trained’ (by feeding them the datasets) to facilitate this learning.

Depending on the type of data set being used and the desired outcome, generative AI training techniques can involve deep learning, adversarial learning, reinforcement learning, and more.

#1. Generative Adversarial Networks (GANs)

Generative Adversarial Networks, or GANs, are also a type of neural network used in machine learning to generate new data from existing information. There are two main components of GANs – a generator and a discriminator.

• Generator –It creates new data by analyzing the data pattern based on user input.
• Discriminator – This component evaluates whether the data is real or fake.

Whenever there is user input/prompt, the generator will generate new data, and the discriminator will analyze it for authenticity.  Feedback from the discriminator enables algorithms to adjust the generator parameters and refine the output.

This process continues until the generator produces data indistinguishable from the input information.

GANs have several practical applications across business domains, and so, many popular tools leverage this model to offer useful features:

• StyleGAN –It’s a type of GAN that helps generate high-quality images with realistic fixtures and details in image synthesis.
• CycleGAN – This tooluses GANs for image-to-image translation and converts one style to another.
• DALL-E –It is an AI tool that uses GANs to convert text prompts into images.
• GauGAN-Nvidia has developed this tool which uses GANs to generate realistic landscapes from simple sketches.

#2. Transformer-based models

A Transformer-based model is a type of neural network used for various natural language processing tasks such as machine translation, text summarization, and language understanding. These models majorly power various large language models – the foundation of generative AI.

The Transformer model consists of two main components: the encoder and the decoder. The encoder processes the input sequence while the decoder generates the output sequence.

As we mentioned earlier, a good example of a Transformer-based model is the GPT-3 language model, which can generate coherent and contextually relevant text when given a prompt.

The transformer model uses a mechanism called “self-attention” to identify the relevance of each word in a prompt and how they relate to each other in the context of the input sequence.

Upon understanding logical relationships between words in the prompt, these models are able to understand the instructions well and produce a coherent output.

#3. Variational Autoencoders (VAEs)

Variational autoencoders are deep learning models that generate new data based on an input dataset. VAEs contain two neural networks – an encoder and a decoder. VAEs work by first training an encoder network to reduce the input data to meaningful latent variables that capture the most salient features. The decoder network then learns to take sampled points from that space and convert them back into realistic data outputs. A degree of randomness allows the decoder to create new and diverse outputs that resemble the original inputs.

#4. Diffusion models

Diffusion models are generative deep learning models that create high-fidelity synthetic data by reversing a process in which real data is incrementally corrupted with noise. They work by first taking real data examples and gradually adding noise to destroy the structure and make the examples unrecognizable. Then, a large neural network is trained to remove the noise in fine-grained steps, eventually generating pristine new examples similar to the original real data.

Check out our blog “How Generative AI Works” for a detailed breakdown of how each of these models works.

#1. Text generation

This is a use case of generative AI contributing the most to the rising popularity of AI adoption in content creation. Generative AI tools like ChatGPT are widely used by individuals and businesses alike.

Text generation with generative AI models reduces the time and effort required to create new content. This is especially helpful for marketing campaigns where businesses must produce large amounts of content quickly and efficiently.

Moreover, these tools can also help create text-based reports and perform complex business calculations.

The image above showcases an example of using chatGPT to calculate the return on ad spending through a prompt. Similarly, you can use it for business reports and calculations.

#2. Sentiment analysis

Sentiment analysis is another use of generative AI, which involves text analysis to determine the user’s sentiment or emotion. This can be useful for companies that want to monitor customer sentiment toward their products or services. Sentiment analysis can also be used in social media monitoring, market research, and more.

Take an example of a generative AI tool that helps analyze the sentiment behind any written text. It analyzes the syntax and context of the text to provide whether the sentiment is positive or negative.

#9. Synthetic data generation and augmentation

Synthetic data generation involves creating unique data from the input of the original dataset. This is useful when there is not enough data to train a machine-learning model or when it is difficult to obtain new data.

Synthetic data can generate images of objects that do not exist in the real world, such as a new type of car or a fictional creature.  For example, Dall-E uses multiple models, including a transformer, a latent representation model(LRM), and CLIP, to translate English phrases into code.

Further, this code generates images and ranks existing images based on how closely they relate to the given phrase.
