Workshop: XXAI: Extending Explainable AI Beyond Deep Models and Classifiers

Invited Talk 3: Grégoire Montavon - XAI Beyond Classifiers: Explaining Anomalies, Clustering, and More

Wojciech Samek


Abstract:

Unsupervised models such as clustering or anomaly detection are routinely used for data discovery and summarization. To gain maximum insight from the data, we also need to explain which input features (e.g. pixels) support the cluster assignments and the anomaly detections.—So far, XAI has mainly focused on supervised models.—In this talk, a novel systematic approach to explain various unsupervised models is presented. The approach is based on finding, without retraining, neural network equivalents of these models. Their predictions can then be readily explained using common XAI procedures developed for neural networks.
