Diabetes is gradually becoming a global challenge owing to the gradual increase in the number of cases of Type 2 diabetes mellitus (T2DM). T2DM is characterized as a state of hyperglycaemia due to abnormal control of insulin levels that eventually affects metabolism. This study aimed to review articles that implement machine learning methods to identify suitable risk factors for prediabetes.
The study adopted the preferred reporting items for systematic review (PRISMA) protocol and research questions were formulated by the identification of synonyms and related terms "predictors and prediabetes and machine learning" from PubMed and Google scholar. Both observational and interventional original articles that were published between 2018 and 2023 were included in this study. Eligibility for inclusion was determined by scanning the article title, abstract, and study methodology section.

Excerpt from the Book
1.2 Introduction to Machine Learning
Machine learning is a discipline that deals with the use of data and algorithms to reproduce human actions. Machine learning is an important domain in the rising field of Data Science. With the application of statistical methods, computer algorithms learn to classify data and make appropriate predictions thus discovering important insights. Machine learning algorithms are categorized as; supervised, semi-supervised, and unsupervised learning methods. Supervised learning is defined by the use of labeled datasets to train the algorithms that it uses to forecast results. Input data, also known as the training data, are subjected to the model and it’s upon the model to adjust the weights until the model appropriately fits the function. The general idea in supervised learning includes defining a learning function y = f(x) from the inputs data x and their corresponding outcomes y. Thereafter, the algorithm is expected to predict the outcomes for the test dataset. Supervised learning is best applied for classification tasks such as disease diagnosis where the outcome is either present or absent. Common supervised methods include can be sub-categorized as regression, decision trees, Naïve Bayes, and support vector machine [3], [5].
On the other hand, unsupervised learning utilizes algorithms to analyze and group unlabelled datasets. These sets of algorithms determine patterns or groups in data. In unsupervised learning, the learning function determines essential features about the distribution of the inputs x and the outcomes y from the training dataset. Afterward, when the unsupervised trained model encounters a test dataset, it determines the outcome of every data record based on the previously learned function. The main unsupervised learning problems include association, clustering, and dimensionality reduction The capability of unsupervised learning algorithms to learn likenesses and variances in data makes these algorithms essential in exploratory data analysis and pattern recognition among other applications. Unsupervised learning methods are applied for the reduction of the number of features in a model using algorithms such as principal component analysis (PCA) and singular value decomposition (SVD).
