Discover Oxford’s groundbreaking GPU-Accelerated LOB Simulator – JAX-LOB. Train AI models faster and smarter with financial data.
An interdisciplinary research team from the University of Oxford recently created the first GPU-accelerated limit order book (LOB) simulator, JAX-LOB.
Google’s JAX is a tool for training high-performance machine learning algorithms. It enables artificial intelligence (AI) models to train directly on financial data in the context of a LOB simulator.
The Oxford research team devised an innovative approach for using JAX to operate a LOB simulator using only GPUs. LOB simulations have traditionally been done on computer processing units (CPUs). AI models can bypass multiple communication steps by running them directly on a GPU chain, which is where modern AI training takes place. According to the Oxford team’s pre-print study paper, this results in a 7x boost in speed.
LOB dynamics are one of the most rigorously researched aspects of finance. LOBs, for example, in the stock market allow full-time traders to retain liquidity during daily sessions. In the cryptocurrency realm, LOBs are accepted by professional investors at practically every level.
Training an AI system to comprehend LOB dynamics is a tough and data-intensive endeavor that relies on simulations due to the nature and complexity of the financial market. And, as simulations become more accurate and powerful, the models trained on them become more efficient and valuable.
Finding strategies to optimize this process, according to the Oxford team’s research, is critical:
“Due to their central role in the financial system, the ability to accurately and efficiently model LOB dynamics is extremely valuable. For example, it might allow a financial company to offer better services or may enable the government to predict the impact of financial regulation on the stability of the financial system.”
JAX-LOB is still in its infancy as the first of its type. The researchers emphasize the need for additional research in their work, although some experts think that it could have a favorable impact in the domains of AI and fintech.
