What is Generative AI? 

Generative Artificial Intelligence (AI) is a branch of Artificial Intelligence (AI) centred on developing algorithms and models capable of producing fresh and lifelike data patterns akin to those found in a training dataset. In simpler terms, Generative AI denotes a category of AI systems proficient in generating entirely novel data. These systems or models undergo training on extensive datasets to glean insights and generate original content based on that acquired knowledge. Therefore, the label "generative" aptly characterises this aspect of AI. Generative AI finds applications across diverse domains, including art, image synthesis, natural language generation, music composition, coding, and more.

 

 

How Does Generative AI Work? 

Generative AI operates in three main phases. These phases are: 

1) Training: Generative AI begins with a foundation, a deep learning model that serves as the basis for different types of Gen AI applications. The most common foundation models, including Large Language Models (LLMs) and multimodal models, are created for applications such as generating text, video, image, sound and music. 

To make a foundation model, practitioners train a deep learning algorithm on huge volumes of raw, unstructured data, such as terabytes from the internet. During training, the algorithm performs millions of 'fill in the blank' exercises to predict the next element in a sequence.

2) Tuning: A foundation model knows a lot about many types of content but often can’t generate specific output types with the desired accuracy. For that, the model must be tuned to a particular generation of content tasks, which can be achieved in various ways, including:

a) Fine-tuning: It involves feeding the model labelled data that are specific to the content generation application, such as prompts or questions the application is likely to receive and corresponding answers in the desired format. 

For example, a team developing a customer service chatbot would create thousands of documents containing labelled customer service questions and correct answers and then feed those documents to the model.

b) Reinforcement Learning with Human Feedback (RLHF): In this case, human users respond to generated content with evaluations that the model can use to update itself for greater relevance or accuracy. 

Often, RLHF involves users scoring various outputs in response to the same prompt. It can be something as simple as having people talk or type back to a Virtual Assistant or chatbot, correcting its output in the process.

3) Generation, Evaluation, and More Tuning: Developers play a crucial role in the ongoing process of assessing the outputs of their Generative AI apps and further tuning the model for enhanced accuracy or relevance. 

Another way to improve a Gen AI app's performance is Retrieval Augmented Generation (RAG), a framework for expanding the foundation model to use relevant sources outside of the training data. This helps supplement and refine the parameters in the original model.

How to Develop Generative AI Models?

Multiple types of generative models exist, and combining the positive attributes of each can create even more powerful models. Let's explore them in details:

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 pit 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 on a 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 how the Generative AI works 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.

The Future of Generative AI

The swift adoption of Generative AI applications has spotlighted the difficulties in rolling out this technology safely and responsibly. Consequently, these early implementation issues have inspired research into better tools for detecting AI-generated images, text and video.

The popularity of Generative AI tools such as Midjourney, ChatGPT, Stable Diffusion, and Gemini has also fuelled an endless variety of training processes aimed at helping developers create AI applications. Very soon, industry and society will also build better tools for tracking the source of information to make more trustworthy AI.

Generative AI will continue to  progress, making advancements in: 

1) Art and Entertainment: AI-generated movies, music, and literature will become more sophisticated and mainstream.

2) Healthcare: AI-created treatment plans and drug discoveries will revolutionise patient care and medical research.

3) Business: AI innovation enhances design, marketing, and customer interactions.

4) Training Tools: These tools will automatically identify best practices in one part of an organisation to help train other employees more efficiently. 

5) Ethical Considerations: The development of Generative AI is guided by ethical principles to ensure its responsible and beneficial use.

6) Daily Integration: Generative AI, with its potential to push the boundaries of creativity and innovation, will become an integral part of our daily lives.
