What is generative AI? Explained Types, Benefits and More

Generative AI has become a hot topic. And with the advent of tools like ChatGPT and Gemini, people are seeing these as harbingers of the age of artificial intelligence. On more practical grounds, the world has only recently discovered their widespread applications and use cases, even though generative AIs date back to the 1960s when Joseph Weizenbaum created the ELIZA chatbot in 1961.

Ever since its inception, generative AI has had many waves of breakthroughs, triggering periods of interest. So, it becomes paramount to get an idea as to what exactly led to a surge, and what possible implications could it bring with it.

What is generative AI?

Generative AIs are deep-learning models that can generate content based on the data they are trained on. This could be text, speech, sounds, images, or any other media. The recent advancements in terms of simplicity and speed have vastly increased their applications. You could ask the AI to write poetry, create a song in the style of your favourite artist, or in any way mimic art to the point that it looks authentic.

The last set of breakthroughs led to advances in computer vision five years ago, and the current advancements in natural language processing have followed, greatly increasing the models' ability to use and understand language. What's even more interesting is that this use extends to things like software code or any other data type.

How does generative AI work?

Generative AI uses machine learning models to learn patterns and relationships in the content it is trained with. IT has the ability to generate new content based on those patterns.

Generative AI models comprise neural networks that recognise patterns and structures in a given set of data to generate content. These are trained with a large amount of unlabeled data, i.e. data that isn't labelled, to identify its characteristics and create what's called foundation models. Foundation models are the base for AI systems, such as GPT-3, that can perform multiple tasks.

1. Training

The training of generative AI begins with training a base model, for example, large language models for text, or equivalent models for image, video, or audio generation. Generative AI models are trained using deep learning on a lot of unstructured data, such as text or media available on the internet. During training, the generative AI model predicts the next element in sequences, for example, the next word in text. Thus, it fine-tunes itself to reduce errors. The result is a neural network that can generate content autonomously based on a prompt. Training requires great computational resources and time.

2. Fine-Tuning

Generative AI foundation models are generalists that need fine-tuning to be specific to a certain task. This will involve adding labeled datasets related to the application, like customer support questions with correct responses for a chatbot. Fine-tuning will increase the accuracy and relevance of the model, although it is often tedious as most of the data used for labeling must be outsourced. Reinforcement Learning with Human Feedback (RLHF) RLHF enhances the performance of generative AI models through human feedback. Users rate or grade outputs, allowing the generative AI model to learn from the corrections and enhance its accuracy or relevance. This is especially useful for fine-tuning interactive generative AI applications, such as chatbots.

3. Generation, Evaluation, and Ongoing Tuning

Generative AI models undergo constant assessment and refinement to enhance their effectiveness. Developers may perform updates every week, making adjustments to enhance accuracy or relevance. Methods such as Retrieval Augmented Generation (RAG) can enrich the generative AI model with external, current information, thereby ensuring improved outputs and greater transparency for users.

What type of data is generative AI most suitable for?

While the variety of data generative AI has proven its proficiency, the different forms of data differ in terms of how suited they are for a generative model. The most suited data types among these are text, data data, image data, time series data, multimodal data, and structural data.

Time-series data can be analyzed to study patterns in historical data for accurate predictions and can be used to predict data such as market trends or maintain contextual relevance. On the other hand, structured data completes and generates synthetic data to augment existing data sets, as in generating new entries or predicting missing values in spreadsheets.

Which technology helped generative AI create convincingly authentic media?

Primarily, 2 technologies led the way in aiding generative AI with the ability to craft media that is convincingly authentic. These consist of: Generative Adversarial Networks or (GANs) and Generative Pre-trained Transformers or (GPT).

Generative Adversarial Networks or (GANs) function using 2 simultaneously trained neural networks. These consist of the generator and the discriminator, and they create new data while evaluating its authenticity.

It is the competition between the two networks that leads to increasingly realistic content. GPT models are based upon the transformer architecture. It uses self-attention mechanisms to process data. With that, GPT models are used for generating text, language translations, text summarisation and answering questions.

When was generative AI open source?

Open-source generative AI burst onto the scene in 2021. This was when tech companies began sharing their groundbreaking models with the public. One notable example is GPT-2, a language model trained on millions of web pages. This has ignited a passionate debate amongst various leaders of the industry.

But again, through accessibility to all, we can foster innovation while driving progress. That is the main aim of generative AI as a technology. Some of these benefits include:

• Transparency to ensure ethical use
• Collaboration and Innovation on a global scale.
• Accessibility and Cost-Effectiveness are needed in order to make it freely available.
• Safeguarding educational use
• Security through continuous scrutiny

What generative AI can create?

1. Text

Generative AI models, especially those based on transformers, can generate coherent and contextually relevant text. They generate content like blogs, articles, reports, emails, and creative writing while taking care of the mundane work of producing drafts for summaries and meta descriptions, leaving ample time for higher-value tasks.

2. Images and Video

Generative AI tools like DALL-E and Stable Diffusion can create realistic images and original art, and do the job of style transfer and image editing and enhancement. Recently developed AI video tools can create an animation directly from a written text prompt and apply special effects to the video far faster and far cheaper than traditional methods can.

3. Sound, Speech, and Music

Generative AI creates natural-sounding speech for products, such as AI chatbots and virtual assistants, as well as audiobook narration.
