Artificial intelligence (AI) has revolutionized various sectors, with healthcare being one of the most promising fields for its application. In health informatics, AI, especially machine learning (ML), has demonstrated significant potential in predicting and managing complex diseases such as diabetes. As the prevalence of diabetes continues to rise globally, accurate early prediction models are paramount in facilitating preventive care and reducing complications. This literature review critically examines recent developments in the use of machine learning algorithms for diabetes prediction, organized thematically to highlight the evolution, key methodologies, and existing gaps in the current research.

Initially, the review explores the early applications of traditional statistical methods and simple machine learning models such as decision trees, rule-based systems, and logistic regression. These initial studies laid the foundation by demonstrating that machine learning could outperform conventional statistical approaches in classifying diabetic and non-diabetic populations (Nair et al., 2014). Early research focused on employing readily available clinical data, such as fasting glucose levels, BMI, age, and family history, to build predictive models. These models often experienced limitations in handling complex, nonlinear relationships and integrating diverse data sources.

Subsequently, the thematic analysis highlights advancements in complex algorithms, including support vector machines (SVM), random forests, and neural networks, which have shown increased accuracy in diabetes prediction. Studies by Wang et al. (2017) and Li et al. (2019) demonstrate that ensemble learning methods can effectively capture intricate data patterns, leading to higher predictive performance. Moreover, deep learning techniques, such as convolutional neural networks and recurrent neural networks, have been introduced to analyze not only clinical data but also image-based inputs like retinal fundus images, expanding the potential for early detection of diabetes-related complications (Kaggle et al., 2018; Zhang & Zhang, 2020).

In the methodological domain, recent research emphasizes the importance of data quality, feature engineering, and model interpretability. Although complex models tend to achieve higher accuracy, they often operate as 'black boxes,' raising concerns about transparency—an essential attribute in clinical decision-making (Liao et al., 2020). Some scholars propose hybrid models that combine symbolic AI with machine learning to enhance interpretability without sacrificing performance (Zhou et al., 2021). The review also discusses the integration of electronic health records (EHRs), wearable device data, and genomic information as multimodal data sources, which pose new challenges and opportunities for developing more robust predictive models (Cheng et al., 2022).

Despite these promising advancements, significant gaps remain. Many studies suffer from limited sample sizes, biases in data collection, and lack of external validation, which hinder generalizability. The heterogeneity of datasets and variations in features across populations lead to discrepancies in model performance. Furthermore, few models are implemented in real-world clinical settings, highlighting the gap between research and practice. Ethical considerations related to data privacy and algorithmic bias are also critical issues underexplored in the current literature (Singh & Sinha, 2021).

In conclusion, the review highlights the rapid progress in applying machine learning to diabetes prediction within health informatics. Techniques have evolved from simple models to complex, multimodal algorithms capable of leveraging diverse data sources. However, challenges related to data quality, interpretability, validation, and real-world applicability remain. Addressing these gaps is crucial for translating research findings into effective clinical tools. Future research should focus on developing explainable AI systems, establishing standardized datasets, and conducting extensive validation across different populations to ensure reliable, equitable, and ethically sound applications. This understanding will inform the continuation of the research, guiding efforts toward more practical, accurate, and accessible AI-based predictive models in diabetes care.
