Abstract

The Thyroid gland is a vascular gland and one of the most important organs of a human body. This
gland secretes two hormones which help in controlling the metabolism of the body. Thyroid disease is a major cause
of formation in medical diagnosis and in the prediction, onset to which it is a difficult axiom in the medical research.
The two types of Thyroid disorders are Hyperthyroidism and Hypothyroidism. When this disorder occurs in the
body, they release certain type of hormones into the body which imbalances the body’s metabolism. Thyroid related
Blood test is used to detect this disease but it is often blurred and noise will be present. Data cleansing methods were
used to make the data primitive enough for the analytics to show the risk of patients getting this disease. The
machine learning plays a decisive role in the process of disease prediction and this paper handles the analysis and
classification models that are being used in the thyroid disease based on the information gathered from the dataset
taken from UCI machine learning repository. In this paper few machine learning techniques for diagnosis and
prevention of thyroid.
