## Machine Learning Anomaly Detection

Machine learning anomaly detection involves using advanced algorithms to automatically identify patterns in data that do not conform to expected behavior. Unlike static threshold filters, these models learn the normal characteristics of a market and adapt as conditions evolve.

In high-frequency trading, they are used to detect unusual order flow, potential wash trading, or system malfunctions in real-time. By leveraging neural networks or clustering algorithms, these systems can flag complex anomalies that traditional statistical methods might miss.

This technology is increasingly vital for maintaining the integrity of decentralized finance protocols and centralized exchange order books. It provides a proactive layer of defense against manipulation and technical failures.

Implementing these models requires large, high-quality datasets and continuous training to remain effective. It is at the forefront of modern market surveillance and risk management.
