As a leading risk factor for chronic illnesses, obesity highlights the critical need for prompt diagnosis and active management. This research introduces an innovative expert system developed to precisely categorise obesity severity and offer individualised treatment advice. Utilising the SEMMA data mining framework alongside the tidymodels ecosystem, the study assessed five machine learning algorithms: decision tree, random forest, multinomial logistic regression (MLR), Naive Bayes, and support vector machine (SVM). Achieving the highest predictive accuracy (97.48%), MLR was chosen as the definitive model. The platform incorporates an intuitive R Shiny interface, promoting seamless real-time user engagement. Treatment protocols are formulated via if-then rule-based logic to guarantee customised advice for every obesity classification. A comparative evaluation emphasises the system's exceptional diagnostic precision and its functional utility in recommending treatments. By improving accessibility—especially for marginalised rural communities—this system bolsters public health by facilitating preliminary diagnosis, specific interventions, and forward-looking obesity care.

The rapid expansion of artificial intelligence (AI) systems across numerous sectors in recent years has drawn significant attention to the ethical, legal, and societal aspects (ELSA) of these technologies, along with the specific difficulties they introduce. This paper outlines an ELSA curriculum tailored for data scientists. The framework is designed to heighten awareness of ELSA dilemmas in professional practice, establish a shared vocabulary with domain experts to facilitate collaborative problem-solving, and ultimately imbed ELSA principles directly into data science workflows. Rather than being treated as an obstacle or an auxiliary requirement, ELSA ought to be viewed as an essential component of the Data Science Project Lifecycle. The proposed educational model utilizes the CRISP-DM (CRoss-Industry Standard Process for Data Mining) framework as its structural foundation, creating a vertical division composed of modules that align with each CRISP-DM stage. Vertically intersecting these phases is a horizontal division comprising three distinct thematic strands: ethical and societal, legal, and technical rendering knowledge units (KUs). Alongside an exhaustive breakdown of these KUs, this paper examines practical implementation factors, including course duration, delivery formats, assessment methods, and strategies for managing the diverse baseline knowledge and varying requirements of the target student body.
