The evolutionary journey of generative AI

Generative AI is not a new concept; it has been around since the 1960s, initially appearing in chatbots. However, generative AI gained significant traction in 2014 with the introduction of Generative Adversarial Networks (GANs). These networks could create convincingly authentic images, videos, and audio of real people. 

Since then, the technology has evolved rapidly with transformers and large language models (LLMs) playing a critical role in its mainstream adoption. 

The journey from simple algorithms to complex neural networks has been nothing short of revolutionary, and the future promises even more advancements.

How generative AI works

Generative AI models leverage different learning approaches, including unsupervised or semi-supervised learning for training. This allows organizations to easily and quickly use a large amount of unlabeled data to create foundation models. 

Foundation models can then be used as a base for AI systems that can perform multiple tasks. Examples of such foundation models include GPT-4 and Stable Diffusion. The algorithms behind these models are complex but incredibly effective, often mimicking the human brain's neural pathways to generate realistic and coherent outputs.

The promise of this new technology is that it will transform industries that are still heavily reliant on the human touch. One such sector is banking and financial services, where a range of activities from personalized customer care to financial analysis, reporting, and risk management still require specially trained professionals to run.

Financial services institutions that embrace generative AI can thus be at the forefront of this transformation.

To do so, it’s worth to understand what exactly we mean by generative AI. What are the underlying models and their different use cases, and how do you choose the right one for the job? 

Let’s dive in.

Evaluating generative AI models

When evaluating a generative AI model, there are three key requirements to consider:

  1. Quality: The generated outputs should be of high quality. When it comes to the financial services industry, the model has to be as accurate as possible, as confident-sounding hallucinations would have dramatic consequences.

  2. Diversity: A good generative model should capture the minority modes in its data distribution without sacrificing generation quality.

  3. Speed: Many applications require fast generation, such as real-time image editing. These criteria are essential for assessing the effectiveness of a generative model and ensuring that it meets the specific needs of various applications.

While generative AI has become more of a catch-all phrase, it actually covers different technological approaches. The next section will provide a quick overview of the different kinds of models in use, and what they empower.

Types of generative AI models: an overview

types of generative ai models

Understanding the different types of generative AI models can help us grasp the technology's versatility and potential.  

Let’s take a closer look at a handful of the most noteworthy gen AI models:

  • Diffusion models

  • Variational Autoencoders (VAEs)

  • Generative Adversarial Networks (GANs)

  • Transformers

  • Recurrent Neural Networks (RNNs)

Diffusion Models

Diffusion models, or denoising diffusion probabilistic models (DDPMs), are generative models that use a two-step process of forward and reverse diffusion to create high-quality outputs. 

These models excel at identifying subtle patterns, making them valuable for compliance or certain risk management processes. 

Additionally, diffusion models are optimal for synthetic data generation, which is useful for training AI models for fraud detection. However, they are computationally intensive and may not be ideal for real-time applications.

Variational Autoencoders (VAEs)

Variational Autoencoders (VAEs) are a type of generative model that consists of an encoder and a decoder. The encoder compresses input data into a latent space, and the decoder reconstructs the original data from this compressed form.

While VAEs are particularly useful for image or text generation due to their generative modeling abilities, within financial risk management they excel at tasks that require speed and efficiency, such as real-time fraud detection.

While they may not produce outputs as detailed as diffusion models, their faster processing times make them a practical choice for scenarios where quick anomaly detection at scale is essential. 

VAEs offer a balanced trade-off between quality and computational efficiency, making them a versatile tool in the generative AI landscape.

Generative Adversarial Networks (GANs)

Generative Adversarial Networks (GANs) are a class of generative models that consist of two neural networks: a generator and a discriminator. The generator creates new data, while the discriminator evaluates its authenticity, and the two networks are trained together to improve their performance.

GANs have gained prominence for their ability to produce highly realistic and detailed outputs, making them a strong choice for complex fraud detection tasks in the banking sector. Their capacity to generate data that closely mimics real-world transactions allows for more accurate and robust fraud detection systems than the traditional rules-based approaches.

Trained on historical data, they can accurately tell legitimate transactions while excelling at anomaly detection to predict if a transaction is fraudulent or not.

However, GANs can be computationally intensive and may require significant resources for training and deployment. Despite these challenges, their high-quality outputs make them a compelling option for fintech companies looking to enhance their fraud detection capabilities.

Transformers

Though not traditional generative models, transformers like Google's BERT and OpenAI's GPT are effective in natural language processing (NLP) tasks and are incredibly versatile. Transformers have been adapted for various applications in generative AI, thanks to their highly parallelizable architecture and ability to handle sequences effectively.

Transformers have become increasingly popular in fintech for their versatility and efficiency. They can encode not just text but also transactional data, making them highly effective for both fraud detection and risk assessment. Additionally, their parallel processing capabilities enable quick decision-making, which is crucial in real-time applications.

Transformers also power virtual assistants, which can either augment the ability of risk analysts, help customer service agents, or act as customer-facing chatbots. 

While training generative AI models like transformers may require substantial computational resources, their speed, and adaptability make them valuable assets for organizations aiming to bolster their risk management systems.

Recurrent Neural Networks (RNNs)

Recurrent Neural Networks (RNNs) are a class of neural networks designed to handle sequential data by maintaining a form of internal memory. This allows them to capture temporal dependencies, making them well-suited for tasks involving time-series data.

RNNs are often employed for fraud detection in time-sensitive transactions and for assessing risk in financial market trends. Their ability to capture sequential patterns enables them to identify irregularities over a period, providing a dynamic approach to fraud detection

However, RNNs can be prone to issues like vanishing or exploding gradients, making them less efficient for long sequences. Despite these limitations, their proficiency in handling time-series data makes them a useful tool for specific fraud and risk assessment scenarios in fintech.
