What is Generative AI? 

Generative Artificial Intelligence, also called Generative AI (or Gen AI), is a category of AI that can help create new content and ideas, including stories, images, videos, conversations, and music. It can learn art, chemistry, biology, human language, programming languages, or any other complex subject matter.

It reuses what it knows (and is trained with) to solve new problems. For instance, it can learn English vocabulary and generate a poem from the words it processes. Your organisation can leverage Generative AI for various purposes, such as media creation, chatbots, product development, and design.

 

 

How Does Generative AI Work? 

Like all forms of Artificial Intelligence, Generative AI uses Machine Learning models pre-trained on vast amounts of data. These models can be categoried as the following:

1) Foundation Models: Foundation models are ML models trained on a broad spectrum of generalised and unlabelled data. They're capable of a wide variety of general tasks. Consider these examples: 

a) In the case of image generation, the model analyses the image and generates a sharper, more clearly defined version.

b) With text, the model predicts the next word in a text string based on previous words and their context. Then, it selects the next word using probability distribution techniques.

2) Large Language Models (LLMs): LLMs are one class of foundation models. For instance, OpenAI's Generative Pre-trained Transformer (GPT) models are LLMs. These models are focused explicitly on language-based tasks such as such as: 

a) Summarisation

b) Text generation

c) Text classification

d) Open-ended conversation

e) Information extraction

How to Develop Generative AI Models?

Multiple Types of Generative AI exist, and combining the positive attributes of each can create even more powerful models. Let's explore them in detail:

1) Diffusion Models: Also named Denoising Diffusion Probabilistic Models (DDPMs), diffusion models determine vectors in latent space through a two-step process during training: Forward and reverse diffusion. 

a) Forward Diffusion: This process slowly adds random noise to training data. 

b) Reverse Diffusion: This process reverses the noise to reconstruct the data samples.

Thanks to this two-step process, hundreds of layers can be trained, which helps diffusion models deliver the best quality output when building Generative AI models.

2) Variational Autoencoders (VAEs): VAEs comprises of two neural networks, the encoder and decoder. An encoder converts the input into a more miniature, dense data representation. This compressed representation preserves the information required for a decoder to rebuild the original input data while eliminating irrelevant information. 

The encoder and decoder work in tandem to learn an efficient and straightforward latent data representation. This enables the user to sample new latent representations with ease, that can be mapped through the decoder to generate novel data.

3) Generative Adversarial Networks (GANs): GANs were the most used methodology out of these three before the recent success of diffusion models. GANs provide a strong example of Adversarial Search in Artificial Intelligence in practice, pitting these two neural networks against each other:

a) Generator: This network generates new examples.

b) Discriminator: This network can distinguish the generated content as either fake (generated) or real (from the domain).

Drawbacks of Generative AI 

Generative AI carries immense potential for optimising and streamlining business processes and personalising customer interactions. However, it is worth recognising that Generative AI has its share of risks and limitations. Here are some potential drawbacks associated with Generative AI that you need to be aware of:

1) Adaptability Issues: Generative AI models may need help tuning their outputs to new circumstances. This requires constant fine-tuning and adjustment to ensure it stays relevant and accurate.

2) Harmful Bias: Since Generative AI models are built upon the foundation of data, they may inherit certain biases from that training data into their outputs. Organisations must have policies to detect and address biased content to avoid inadvertently spreading harmful preconceptions.

3) Lack of Transparency: The focus on ease of use and conversation-like input/output certainly has its upsides. But it has created an environment where it takes time to understand exactly How Does Generative AI Work and the source of its original data. Many organisations might not opt for Generative AI without having a clearer picture of its inner workings.

4) Intellectual Property Rights: Despite the advanced nature of today's Generative AI, they still need training on available data to produce content. This creates murky waters especially regarding copyrighted materials since AIs may be using intellectual property that doesn't belong to their parent organisation. Meanwhile, users who share confidential information with AIs may discover that the data's confidentiality has been lost by becoming part of the AI data set.

5) New Cyber Security Dangers: Cyber criminals are already using Generative AI programs to circumvent security layers and target their victims more effectively. Attackers may even utilise the vulnerabilities of company-based AIs as system entry points to gain access to sensitive data. Keeping current on cyber security advancements and vulnerability patches is the only way to battle these growing threats.

6) Potential Accuracy Issues: One major problem associated with Generative AI systems is that they may make up answers in what is referred to as Generative AI 'hallucinations'. It is vital to carefully assess the outputs for accuracy and usefulness before publicly distributing any information created by a Generative AI.
