IBM Watson Machine Learning
You can use IBM Watson Machine Learning to perform payload logging, feedback logging, and to measure performance accuracy, runtime bias detection, drift detection, explainability, and auto-debias function in IBM Watson OpenScale.
IBM Watson OpenScale fully supports the following IBM Watson Machine Learning frameworks:
Table 1. Framework support details
|Framework||Problem type||Data type|
|AutoAI1||Classification (binary and multi classes)||Structured (data, text)|
|AutoAI||Regression||Structured or Unstructured2 (text only)|
|Apache Spark MLlib||Classification||Structured (data, text)|
|Apache Spark MLLib||Regression||Structured (data, text)|
|Keras with TensorFlow3&4||Classification||Unstructured2 (image, text)|
|Keras with TensorFlow3&4||Regression||Unstructured2 (image, text)|
|Python function||Classification||Structured (data, text)|
|Python function||Regression||Structured (data, text)|
|scikit-learn||Classification||Structured (data, text)|
|scikit-learn||Regression||Structured (data, text)|
|XGBoost5||Classification||Structured (data, text)|
|XGBoost||Regression||Structured (data, text)|
1To learn more about AutoAI, see AutoAI implementation details. For models where the training data is in Cloud Object Storage, there is no support for fairness attributes of type boolean. However, if the training data is in Db2, Watson OpenScale supports fairness attributes that are boolean type. When using the AutoAI option, Watson OpenScale does not support models where the data type of the model prediction is binary. You must change such models so that the data type of their prediction is a string data type.
2Fairness and drift metrics are not supported for unstructured (image or text) data types.
3Keras support does not include support for fairness.
4Explainability is supported if your model / framework outputs prediction probabilities.
5For XGBoost binary and multiple class models, you must update the model to return prediction probability in the form of numerical values for binary models and a list of probabilities per class for multi-class models. Support for the XGBoost framework has the following limitations for classification problems: For binary classification, Watson OpenScale supports the
binary:logistic logistic regression function with an output as a probability of
True. For multiclass classification, Watson OpenScale supports the
multi:softprob function where the result contains the predicted probability of each data point belonging to each class.
AutoAI models and training data
AutoAI automatically prepares data, applies algorithms, or estimators, and builds model pipelines best suited for your data and use case. Watson OpenScale requires access to the training data to analyze the model.
Because Watson OpenScale cannot detect the training data location for an AutoAI model like it can for a regular model, you must explicitly provide the needed details to access the training data location:
- For the online path, where you manually configuring monitors, you must provide the database details from which training data can be accessed .
- For the custom notebook path, where you upload training data distribution, you can use the JSON file that is produced by running the notebook.
Specifying an IBM Watson Machine Learning service instance
Your first step in the Watson OpenScale tool is to specify an IBM Watson Machine Learning instance. Your Machine Learning instance is where you store your AI models and deployments.
You should have provisioned an IBM Watson Machine Learning instance in the same account or cluster where the Watson OpenScale service instance is present. If you have provisioned a IBM Watson Machine Learning instance in some other account or cluster, then you will not be able to configure that instance with automatic payload logging with Watson OpenScale.
Connect your Machine Learning service instance
Watson OpenScale connects to AI models and deployments in an IBM Watson Machine Learning instance. To connect your service to Watson OpenScale, go to the Configure tab, add a machine learning provider, and click the Edit icon. In addition to a name and description and whether this is a Pre-production or Production environment type, you must provide the following information that is specific to this type of service instance:
- If you have an instance of IBM Watson Machine Learning, Watson OpenScale detects it, along with the configuration information.
- To specify a machine learning location outside of your account, choose the Other option. Provide credentials for your location by pasting valid JSON credentials.
You are now ready to select deployed models and configure your monitors. Watson OpenScale lists your deployed models on the Insights dashboard where you can click the Add to dashboard button. Select the deployments you want to monitor and click Configure.
For more information, see Configure monitors.
