Accurate AI-Based Chatbot to Diagnose Heart Diseases Pre-Human Doctor Consultation
Bibliographic record
Abstract
Early diagnosis of heart disorders is an essential issue since they might be life-threatening conditions that call for urgent medical care.Chatbots as a user-friendly technology can be used to deliver general assistance and information anywhere anytime.However, the decision-making accuracy is one of the key challenges of Chatbots.In this paper, a medical Chatbot is developed for the purpose of early cardiac disease diagnosis based on given symptoms.An approved dataset known as the Cleveland Heart Disease dataset is utilized in this work.Hence, for accurate decision-making, three machine learning algorithms Support Vector Machine (SVM), and Logistic Regression (LR), and Extreme Gradient Boosting (XGBoost) are compared and tested to nominate the best algorithms for heart health disorders detection.Three simulation scenarios are applied to test the performance of each algorithm using first all features of the dataset, then the k-best feature selection method, and the application of Grid Search (GS) optimization algorithms.The performance evaluation shows that the prediction accuracy of the proposed XGBoost algorithm outweighs other algorithms.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
