[150 mins] Unsupervised/self-supervised approaches (given only normal training data

10:15 – 10:45 am Coffee break

11:45 – 1:00 pm Lunch break

[60 mins] Weakly-supervised AD/ Open-set AD (given some anomaly training examples, in additional to normal training data)

[60 mins] Weakly-supervised approaches  (given video-level labels, to detect frame-level anomalies

3:00 – 3:30 pm Coffee break

[60 mins] Anomaly segmentation (with a specific focus on autonomous driving settings)
