What is Generative AI?

Generative AI refers to a class of artificial intelligence algorithms that can generate new data from existing data. Unlike traditional machine learning models designed for classification, regression or clustering, to cite the most common applications, generative AI models create new content, whether it be text, images, or, in our context, financial data. This is achieved through specific techniques that allow deep-learning algorithms to self-teach complex relationships across data and encode useful representations from which to draw realistic samples.

How Generative AI Works

Generative AI typically relies on the concept of the encoder-decoder architecture. These two work together to produce meaningful representation of the data in such a way that mathematical concepts such as similarities and distributions assume a precise meaning. This step is fundamental to the action of generating new data.

Among the first to be applied successfully to real use cases, Generative Adversarial Networks (GANs) refine the accuracy of the generative step by comparing how realistic the generated output is in relation to real data. The secret sauce is the introduction of two components trained to “fight” each other (from which “Adversarial”). The two components work in tandem within a framework where one creates data and the other provides feedback to improve the quality of the generated data over time.

For example, GANs can generate synthetic financial data by sampling from a representation space that encodes the structure of the learned data examples. However, they have been shown to suffer from challenges in modeling multivariate dynamics and large-scale temporal structures, which are crucial in financial markets. Also, they are hard to train and suffer from the phenomenon of model collapse, an occurrence where the generated data is corrupted but the discriminating component mistakes it for real data.

Recent advancements have shown that denoising-diffusion architectures can be more effective for generating synthetic data samples and have better scaling laws, meaning that making the network larger makes it better at the task while not adding substantial issues to training, other than costs. Moreover, the idea of conditional diffusion proved to be a decidedly more effective way to synthesize data with specific features rather than sampling from very complex multivariate distributions till the desired data is produced.

Nowadays, more and more industries are turning to AI generated synthetic data to solve some of their biggest challenges like training self-driving cars without actually driving them, teaching production line robots their tasks within synthetic virtual environments, creating new molecules to targets specific chemical reactions important to fight diseases or parasites.

Applications of Generative AI in Quantitative Trading

Generative AI has the potential to revolutionize quantitative trading by addressing several key challenges and enhancing the robustness of trading strategies.

Synthetic Data Generation

Data Augmentation: Generative AI can create synthetic datasets that enrich historical financial data. This allows quantitative models to be trained on a more diverse set of scenarios, improving their generalizability and robustness.

Scenario Simulation: By simulating various market conditions, including rare and extreme events, generative AI enables stress-testing of trading strategies, ensuring they perform well under different conditions.

Risk Management

Enhanced Predictability: By generating realistic and diverse synthetic data, generative AI helps in understanding the potential risks and returns associated with different trading strategies.

Robust Testing: The generated data can be used to backtest trading algorithms under various hypothetical scenarios, providing insights into their potential performance.

Model Improvement

Generalization: Synthetic data helps prevent overfitting by providing a broader training dataset, ensuring that models learn to generalize better rather than memorizing specific patterns.

Explainability: Techniques like conditional diffusion offer an interpretable framework, providing clearer insights into model predictions and behavior.
