EASI AI Demo Guide

1. Go to https://demo.belle.ai and select the AI module.

2. Upload a corresponding image. You will have the option to add multiple images (look for the plus sign that will appear after the first image is uploaded).

3. Then, the AI will analyze the image.

• The model will produce an AI-predicted EASI score and clinicians may move the slider bars to create a Clinician Adjusted Score.
• The Oops Score checks if the image contains human skin. An Oops score of 1 means the image does not contain any skin.
• The Image Quality Score evaluates image blur and sharpness. The larger the score, the better (0.0 - 1.0).
• Erythema/Redness, Edema/Papulation, Excoriation, and Lichenification are graded on a scale from 0 to 3. You may click on their respective circles to visualize the AI-generated heatmap for each of these conditions that was used to calculate those 4 gradings.
• The computation of EASI score is as follows: bodypart_factor * affected_area * (redness+induration+papulation+excoriation). In this example, it is a local computation of EASI so we do not have the information of body part; thus, we replace this factor by 6 (which would be the maximum). Then for this example, the score would be: 6 * affected_area (which is about 54%) * (0.7 + 1 + 1 + 0.8)
• You may add notes or comments under “What do you think about the result?” You may check the box of what condition you believe is present. Your input will not change any scoring.

4. You may revisit previous analyses via the History tab (located on the sidebar) which automatically saves previous results. Note: comments on such analyses must be saved manually by clicking the “Save" button.
