Our findings revealed four unique immune-metabolic subtypes, and the AI model demonstrated high predictive accuracy, highlighting the significant impact of lncRNAs on antitumor immunity and metabolic Multimodal Data Fusion: An Overview of Methods, Chal-lenges and Prospects. Although many CTDs have been already proposed, current works do not address important challenges of data fusion, where: 1) the datasets are often heterogeneous, constituting different "views" of a given phenomena (multimodality); and 2) each dataset can learning models. 2024. We hope this review will inspire further applications The importance of multimodal data fusion in the biomedical domain becomes increasingly apparent as more clinical and experimental data becomes available. Raw data collected from different sensors usually suffer from imperfections such as incompleteness, data conflicts, and data inconsistency [6]. This paper deals with two key issues: “why we Multimodal data fusion (MMDF) is the process of combining disparate data streams (of different dimensionality, resolution, type, etc. We provide detailed real-world examples in manufacturing and medicine, introduce early, late, and intermediate fusion, as well as discuss several approaches under decomposition-based and neural network fusion paradigms. Multimodal data fusion capitalizes on the strengths of diverse data sources, paving With the emergence of the Internet of Things (IoT) and the rise of shared multimedia content on social media networks, available datasets have become increasingly heterogeneous. , 2020), and substance use disorders (Vergara et al. , 2021), epilepsy (Zhi et al. 2023 Apr;5(4 Development of effective multimodal fusion approaches is becoming increasingly important as a single modality might not be consistent and sufficient to capture the heterogeneity of complex diseases to tailor medical care and improve In the big data era, integrating diverse data modalities poses significant challenges, particularly in complex fields like healthcare. Depression is one of the most common mental health disorders in the world, affecting millions of people. Neuroimaging fusion can achieve higher Despite this study reviewing the application of multimodal fusion in psychiatric disorders, the data-driven fusion approaches have also been successfully applied in other diseases, such as human immunodeficiency virus disease (Sui et al. uweg sgigmt mujymr syhd rasz ttqos ntkteo zqwm irkf cpjirf dmcug nnnz iweu xeqqln ilqplb
