Early and efficient identification of thyroid disease is important for improved clinical intervention and disease management. By combining sophisticated and advanced machine learning models with a range of advanced feature selection strategies, this research study aims to enhance the classification of thyroid disease based on a machine learning based diagnostic system. The preprocessed dataset used in this study and the trials were taken from the machine learning repository at the University of California, Irvine (UCI) .  \nWe employ two popular feature selection techniques- Chi-Square, and Recursive Feature Elimination, and a dimensionality reduction technique Linear Discriminant Analysis (LDA), and to choose the best features from the dataset for experiments. After selecting the most suitable features, they were then used to train and test the machine learning models: MultiLayer Perceptron (MLP), Gradient Boost (GB), and Recurrent Neural Network (RNN) . Evaluation matrices, accuracy, precision, recall, and F1-score were used to assess models'performance. The experimental results show that the machine learning model Gradient Boost (GB) outperformed the other models and yielded an accuracy of 99%, indicating its ability to classify the Thyroid Disease (TD) accurately. The proposed research work helps to create an intelligent decision-support system for medical diagnostics by offering an understandable and reliable framework for Thyroid Detection.  \nKeywords: Thyroid Disease, Hormones, Feature Selection, Linear Discriminant Analysis, Chi-Square, Recursive Feature Elimination, Machine Learning Based Diagnostic System  \nOctober 2025 |Vol 07 | Issue 04 Page |2383  \nIntroduction:  \nThe thyroid, one of the body’s most vital organs, produces hormones essential for numerous physiological processes. Once released into the bloodstream, these hormones circulate throughout the body, regulating growth and metabolism. This indicates that the thyroid directly influences how the body utilizes energy and sustains overall physiological balance. The thyroid gland is perfectly positioned to perform its functions because it is located in the neck, just below the Adam's apple. Understanding thyroid function is essential, as it serves as a key basis for investigating and diagnosing various disorders linked to hormonal imbalances. By producing hormones necessary for growth and metabolism, the thyroid ensures that the body's energy needs are met, promoting overall health and well-being [1] . Thyroid disease is ranked 2nd after diabetes by the prominent healthcare organization WHO (World Health Organization) .
