Novelty Detection refers to the computational process of identifying data points or patterns that deviate significantly from previously observed or learned normal behavior within a dataset. In crypto systems, its purpose is to identify unusual market conditions, anomalous trading activities, or potential security threats that signal a departure from established norms. It isolates the unusual.
Mechanism
The system typically trains on a baseline dataset representing normal operational or market behavior, constructing a model of what constitutes “normal.” Subsequent real-time data streams are then compared against this learned model. Any data point exhibiting a statistically significant divergence from the model’s expectation is flagged as a novelty.
Methodology
This approach frequently utilizes unsupervised learning algorithms such as autoencoders, one-class SVMs, or density-based clustering to establish the boundaries of normal behavior without requiring labeled anomaly data. In crypto contexts, this method is critical for identifying flash crashes, manipulative trading, or previously unseen exploit attempts by continuously monitoring network activity, transaction patterns, and market microstructure for unexpected shifts.
