New LOB-ID framework evaluates synthetic market data using AI embeddings

Researchers have introduced LOB-ID, a novel framework for evaluating synthetic market data generated by AI models. This framework adapts existing embedding-based metrics like Fréchet Inception Distance (FID) and Monge Inception Distance (MIND) to the specific domain of limit order books (LOBs). By training the DeepLOB architecture on extensive LOB data, LOB-ID can assess the temporal and cross-level structure of order-book trajectories, proving more sensitive to distortions than traditional methods.
