Regions highlighted in red represent the ground-truth anomaly segments. The blue line is the log-likelihood or anomaly score output by SDFVAE. <br>
We are able to determine the anomalies via a specific threshold, due to the lower the log-likelihood the higher the anomaly score. <br>
Since we do not focus on the thresholding technique, in practice, the threshold for detecting anomaly from the anomaly score can be selected by the best F1-score. <br>
