 Anomaly detection has especially in the industrial and automotive field essential importance.
 Lots of assembly lines need visual inspection to find errors often with the help of camera systems.
 Machine learning helped the field to advance a lot in the past.
-Most of the time the error rate is sub $.1%$ and therefore plenty of good data is available and the data is heavily unbalaned.
+Most of the time the error rate is sub $.1%$ and therefore plenty of good data and almost no faulty data is available.
+So the train data is heavily unbalaned.#cite(<parnami2022learningexamplessummaryapproaches>)
 
 PatchCore and EfficientAD are state of the art algorithms trained only on good data and then detect anomalies within unseen (but similar) data.
 One of their problems is the need of lots of training data and time to train.
 Moreover a slight change of the camera position or the lighting conditions can lead to a complete retraining of the model.
-Few-Shot learning might be a suitable alternative with hugely lowered train times and fast adaption to new conditions.

 In this thesis the performance of 3 Few-Shot learning algorithms will be compared in the field of anomaly detection.
 Moreover, few-shot learning might be able not only to detect anomalies but also to detect the anomaly class.
