Unit Testing Machine Learning Pipeline

The Azure CAT ML team have built the following GitHub Repo which contains code and pipeline definition for a machine learning project demonstrating how to automate an end to end MLAI workflow. Let us now practically understand the pipeline and implement it.

Machine Learning Pipeline Deployment Architecture And Tools

Back to a previous model version or if you need to produce evaluation metrics for a previous model version when the pipeline is given new test data during the model validation step.

Unit testing machine learning pipeline. Pull the source code from source control. Once machine learning pipelines are built and automated deployment into production can proceed followed by the monitoring optimization and maintenance of models. Unit testing is a method of software testing that checks which specific individual units of code are fit to be used.

First we need to import pipeline from sklearn. Add intelligence and efficiency to your business with AI and machine learning. How Machine Learning Pipeline Works.

Each stage of a pipeline is fed with the data processed from its preceding stage ie the output of a processing unit supplied as an input to the next step. For now notice that the Model the black box is a small part of the pipeline infrastructure necessary for production ML. The build pipelines include DevOps tasks for data sanity test unit test model training on different compute targets model version management model.

Lint any configuration files. Unit testing the different methods implemented in your model. Call the score function to check the score.

Now call the fit function on the pipeline. Explore unit testing in tensorflow code using tftest mocking and patching objects code coverage and different examples of test cases in machine learning applications. Role of Testing in ML Pipelines.

A schematic of a typical machine learning pipeline. We know that 1236 so it. A pipeline consists of several stages.

Well become familiar with these components later. Define the pipeline object containing all the steps of transformation that are to be performed. Assert sum 1 2 3 6.

An ML pipeline consists of several components as the diagram shows. Machine Learning Pipeline consists of four main stages as Pre-processing Learning Evaluation and Prediction. Build a production ready deep learning pipeline.

Run unit tests against the AWS Lambda functions in codebase. For example if you would want to test the sum function in python you could write the following test. Thats why most.

The pipeline contains the following steps as shown in the following diagram. Programming a deep learning model is not easy Im not going to lie but testing one is even harder.
