Classification of Inflammatory Gene Expression Patterns with Machine Learning Models

Published in IEEE, 2023

This study focuses on the analysis of inflammatory gene expression patterns in the parietal cortex (PCx) and temporal cortex (TCx) from a human brain RNA sequence data set, aiming to derive insights into the underlying genetic link associated with dementia, as well as prediction of dementia.
