Methods A group sparse canonical analysis method was proposed, group sparse constraints λ1∥U∥Gand λ2∥U∥Gwere added to traditional canonical correlation analysis model to select features groups. Then, features within each group were selected by sparse constraints τ1∥U∥1and τ2∥V∥1. The group sparse canonical correlation analysis method was used to analyze the correlation between brain regions and genes of schizophrenia, and it's stability and ability were also verified to select biomarkers. Results Several pairs canonical brain regions and genes were identified. The left insula and gene AKT1 produced the most significant correlation, r=0.6538, and the correlations between both right rectus and gene DAOA, MAGI2 were more than 0.6. The correlation coefficients of selected features were (0.626 9±0.016 1) with group sparse canonical correlation analysis and (0.625 5±0.018 1) with sparse canonical correlation analysis. The biomarkers selected by group sparse canonical correlation analysis using 75 related genes to schizophrenia, was higher than using non-related genes randomly. Conclusion Several pairs canonical brain regions and genes can be identified by the group sparse canonical analysis method, which provided a new way for the study of schizophrenia and other complex mental disorders.","is_dataset_classified":null,"base_score":0.0,"endowment":0.0,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"23304386","pmcid":null,"openalex_id":"https://openalex.org/W3127253221","authors":[],"funders":[],"total_grants":0,"fwci":0.0,"citation_percentile":0.31387609,"influential_citations":0,"citation_trend":[],"oa_status":"closed","license":"https://doi.org/10.15223/policy-029","oa_locations":[{"url":"http://xplorestaging.ieee.org/ielx7/9312958/9312977/09313246.pdf?arnumber=9313246","host_type":"publisher"},{"url":"https://doi.org/10.1109/bibm49941.2020.9313246","host_type":""}],"fields_of_study":["Gene expression and cancer classification","Traditional Chinese Medicine Studies","Bioinformatics and Genomic Networks"],"mesh_terms":[],"keywords":["Canonical correlation","Correlation","Artificial intelligence","Computer science","Mathematics"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-02T01:24:37.055424Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
