Description: The SPARKER model uses a sparse ensemble of local Gaussian kernels to detect rare statistical anomalies by enforcing sparsity, locality, and competition. It adapts representation space around imbalances using a Neyman-Pearson test framework, allowing it to decompose anomaly scores into interpretable local features.
