Export Isolation Forest Individual Interpretation / Heatmap

Tamkin Dataiku DSS Core Designer, Registered Posts: 3

The Isolation Forest Report, under "Clusters" & Anomalies has a very nice heat maps highlighting which datapoints are anomalies.

As far as I can tell there is no way to export this heatmap and no way to export a dataset that says which datapoints contributed most to the anomaly score. You can only export the dataset which indicates that the full row is an anomaly.

Amy I missing something? It would be super useful to export this information.

    You need to deploy the model to the flow as a retrainable clustering model. You should then go to that model, open the one version it has (which is the one you just deployed), and from there you should be able to publish. The model in the Lab (which still exist) is never publishable.
