Approach for Easy Visual Comparison between ground-truth and predicted classes

Although classification metrics are good for summarizing a model’s performance on a dataset, they disconnect the user from the data itself. Similarly, a confusion matrix might tell us that performance is suffering because of false positives, but it obscures information about what patterns may have caused those misclassifications and what types of false positives there might be. 

One way to gain interpretability is to group sampled images by the category of their output (true negative, false negative, false positive, true positive), and display them in a powerpoint file for facile review. These visualizable categories make it easy to identify patterns in misclassified data that can be exploited to improve performance (e.g., hard negative mining, or image analysis based filtering).

This blog post describes and demonstrates a workflow that produces such a powerpoint slide deck automatically for review, as shown below:

Computationally creating a PowerPoint presentation of experimental results using Python

This post is an update of the previous post, which discussed how to create a powerpoint slide desk with results using Matlab. In the last couple of years, we have mostly transitioned to python for our digital pathology image analysis, in particular those tasks which employ deep learning. It thus makes sense to port our tools over as well. In this case, we’ll be looking at building powerpoint slide desks using python.

Let’s look at what we want as our final output:

Exporting from Matlab To PowerPoint

Reviewing the results of an image based experiment, across many images, can be annoying in matlab. Too much clicking!

I’ve recently started using PowerPoint to view many of my results. This blog posts discuss how using the free export to PowerPoint toolbox it is possible to create a slide desk with all relevant information for easier viewing. It looks like this:
