Fig. 2From: Sampling inequalities affect generalization of neuroimaging-based diagnostic classifiers in psychiatryGeospatial model for sample population regarding ML models towards neuropsychiatric classification in the world (A) and USA (B). Both maps were built by 1st administrative grid cell, with each country/region for the globe (251 countries/regions) and state for the USA (51 states). For better readability, we re-scaled the sample size by log-transformation. Sample size for a portion of countries/regions has been shown in these maps. A panel was depicted similarly to the Fig. 2A in our previous article [22], because of the overlapping datasets between themBack to article page
