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
ouanomalie
selon qu'une anomalie est présente ou non sur le topic associé :data/d1anomalie data/d2anomalie data/d3anomalie data/d4anomalie data/d5anomalie
- Publiées sur le broker IUT (10.98.35.245) sur les topics :
- En dehors des séances
