Node.js : Détection temps réel d'anomalies de type données aberrantes

Le travail de cette étape va consister à détecter des anomalies de type valeurs aberrantes en temps réel.


Topics de données

  • Pendant les séances :
    • Publiées sur le broker IUT (10.98.35.245) sur les topics :
      data/d1
      data/d2
      data/d3
      data/d4
      data/d5
    • À des fins de contrôle et de validation de vos détecteurs les topics suivants contiennent le message pas d'anomalie ou anomalie selon qu'une anomalie est présente ou non sur le topic associé :
      data/d1anomalie
      data/d2anomalie
      data/d3anomalie
      data/d4anomalie
      data/d5anomalie
  • En dehors des séances
