CIFAR10 Image Classifier Explanations

We will use a Tensorflow classifier built on CIFAR10 image dataset which is a 10 class image dataset to show the example of explanation on image data.

Create the InferenceService with Alibi Explainer

apiVersion: "serving.kserve.io/v1beta1"
kind: "InferenceService"
metadata:
  name: "cifar10"
spec:
  predictor:
    tensorflow:
      storageUri: "gs://seldon-models/tfserving/cifar10/resnet32"
      resources:
        requests:
          cpu: 0.1
          memory: 5Gi   
        limits:
          memory: 10Gi
  explainer:
    alibi:
      type: AnchorImages
      storageUri: "gs://seldon-models/tfserving/cifar10/explainer-py36-0.5.2"
      config:
        batch_size: "40"
        stop_on_first: "True"
      resources:
        requests:
          cpu: 0.1
          memory: 5Gi 
        limits:
          memory: 10Gi

Note

The InferenceService resource describes:

• A pretrained tensorflow model stored on a Google bucket
• An AnchorImage Seldon Alibi Explainer, see the Alibi Docs for further details.

Test on notebook

Run this example using the Jupyter notebook.

Once created you will be able to test the predictions:

And then get an explanation for it:
