Pour évaluer sans labels, utilisez le « score silhouette » sur les scores d'anomalie ou l’« analyse de l’écart de reconstruction » (autoencoder). Un seuillage efficace : fixez le percentile 95-99 sur les scores, puis validez par inspection visuelle (distribution des scores, t-SNE des features). Code : `np.percentile(scores, 95)` comme seuil initial.
