After a deep learning computer vision model is trained and deployed, it is often necessary to periodically (or continuously) evaluate the model with new test data. This developer code pattern provides a Jupyter Notebook that will take test images with known “ground-truth” categories and evaluate the inference results versus the truth.
We will use a Jupyter Notebook to evaluate an IBM Maximo Visual Inspection image classification model. You can train a model using the provided example or test your own deployed model. The notebook will use test images, which are separated into directories to indicate the expected category classifications. These expected classifications are considered the “ground truth.” The deployed model’s API endpoint will be called to collect the inference results for each image. The collected results are then used to evaluate the actual model performance. Model accuracy is demonstrated by showing a confusion matrix and calculating a variety of the most common statistics used to measure the accuracy of a model.
When you have completed this code pattern, you will understand how to:
Train and deploy an image classification model with IBM Maximo Visual Inspection
Run a Jupyter Notebook
Evaluate the results using a variety of accuracy statistics
Validate existing deployed models with new test data sets
The steps will show you how to:
Create a data set.
Train a model for image classification.
Deploy it to a REST API endpoint.
Validate the model with new data.

Log in to IBM Maximo Visual Inspection.
Create a data set.
Assign categories to images.
Train the model.
Deploy and test.
Run the notebook.
