To overcome these, we propose and tested the usage of uniform manifold approximation and projection (UMAP), a very recent, popular dimensionality reduction technique. We showed its effectiveness by using it on a large Spanish clinical database of patients diagnosed with depression, to whom we applied UMAP before grouping them using a hierarchical agglomerative cluster analysis. By extensively studying its behavior and results, validating them with purely unsupervised metrics, we show that they are consistent with well-known relationships, which validates the applicability of UMAP to advance the study of comorbidities.engAtribución 3.0 Españahttps://creativecommons.org/licenses/by/3.0/es/A Machine Learning Approach for Studying the Comorbidities of Complex Diagnosesjournal articlehttps://doi.org/10.3390/bs9120122open accessComorbiditiesdepressionUMAPhierarchical clusteringPsicología (Psicología)61 Psicología
