Editor's Comment: This is a highly technical study which may prove challenging for a lay audience. However, the implications are profound.This research group has applied a computer algorithm used for data mining and clustering in order to sort symptoms of ME/CFS by frequency and severity.The method used to gather information was the DePaul Symptom Questionnaire (DSQ), developed by Leonard Jason.The study found that 11 symptoms relating to fatigue, post-exertional malaise, sleep dysfunction, neurocognitive problems, and general pain were highly predictive of ME/CFS.
 "This indicates that fatigue, post-exertional malaise, and neurocognitive disorders are the most predictive symptom categories of CFS," concluded the authors. "As such, a CFS case definition should place particular emphasis on these factors." What is most significant about this study is that not only was the application of the algorithm to the DSQ more accurate as a diagnostic tool than any existing case definition, it can be used by any researcher to identify a patient cohort.
 

Identifying Defining Aspects of Chronic Fatigue Syndrome via Unsupervised Machine Learning and Feature Selection
 
By Samuel P. Watson at al.
 
Abstract

In this work we propose an unsupervised machine learning method of predicting chronic fatigue syndrome (CFS) based on the k-means algorithm using self-reported questionnaire responses.

We first suggest a method of determining the presence of a symptom based on its frequency and severity using an unsupervised dynamic thresholding approach. This threshold is used to diagnose subjects with 54 symptoms related to CFS.

Based on these diagnoses, k-means is used to predict the presence of CFS. We find that k-means does not have significantly worse predictive diagnostic accuracy than commonly used CFS case definitions.

After applying supervised feature selection, k-means achieves significantly better diagnostic accuracy than any of the case definitions examined. We use these results to suggest the basis for an empirically founded CFS case definition.

All symptoms are identified by questions. I would like to examine the questions used to elucidate the symptoms. Computer analysis/informatics depends heavily on the question structure.

Questions cause subjective weighting which must be tested for in the analysis. The fact that pain is so low in the list and occurs in only one construct suggests to me that there may be a bias away from pain. Considering that at least 42% of people fitting the Canadian criteria will also fit the criteria for fibromyalgia there is much more pain than this analysis shows.

Otherwise great. Thanks.
