Stacked Autoencoders for Outlier Detection in Over-the-Horizon Radar Signals

<div>The impact of minimum cluster size (OPTICS input parameter) on Davies–Bouldin index average score. Stacked autoencoders CHI scores are better in six out of eight investigated cases, compared to PCA based clusters, and five out of eight cases compared to raw data.</div>
