Cross Validation of AI Suggestions for Nonalcoholic Fatty Liver Disease

A friend got this diagnosis from a naturopath examining blood cells using a microscope. Visual inspection of blood lacks the degree of objectivity that I would prefer (AI imaging of the microscope slides is what I would like to see things evolve to). I went to Microbiome Prescription’s Medical Conditions with Microbiome Shifts from US National Library of Medicine and then look at the candidate suggestions for Nonalcoholic Fatty Liver Disease (nafld) Nonalcoholic .

For information about the Artificial Intelligence approach, see AI Generated Diet Suggestion for Medical Conditions. Note: This is not machine learning but old school fuzzy expert systems.

Out of curiosity, I did a few cross validations for the highest to take and highest to avoid. Everything was in agreement. The few suggested items that I checked were shown to have the desired impact on NAFLD.

The purpose of cross validation is to see how well the Artificial Intelligence Logic (and assumptions) are performing.

I decided to do a deeper cross validation because I found that the treatment literature was relatively abundant. REMEMBER the AI only knows the bacteria shifts and nothing about the diagnosis or treatments.

Discussion

There is a strong bias to publish positive results, hence finding many n/a in the to avoid list is expected. A study show an adverse effect is unlikely to see publication. We see the following ratios:

  • To Take: 22 Right to 2 Wrong, i.e. 92% correct
  • To Avoid: 10 Right to 2 Wrong i.e. 83% correct

This suggests that the n/a ones above are likely to be correct.
