<b>K Nearest Neighbours based diagnosis of hyperglycemia</b> AI or artificial intelligence is the simulation of human intelligence processes by machines, especially computer systems. These processes include learning the acquisition of information and rules for using the information , reasoning using the rules to reach approximate or definite conclusions , and self correction. As a result, Artificial Intelligence is gaining Importance in science and engineering fields. The use of Artificial Intelligence in medical diagnosis too is becoming increasingly common and has been used widely in the diagnosis of cancers, tumors, hepatitis, lung diseases, etc... The main aim of this paper is to build an Artificial Intelligent System that after analysis of certain parameters can predict that whether a person is diabetic or not. Diabetes is the name used to describe a metabolic condition of having higher than normal blood sugar levels. Diabetes is becoming increasingly more common throughout the world, due to increased obesity which can lead to metabolic syndrome or pre diabetes leading to higher incidences of type 2 diabetes. Abid Sarwar have identified 10 parameters that play an important role in diabetes and prepared a rich database of training data which served as the backbone of the prediction algorithm. Keeping in view this training data authors developed a system that uses the artificial neural networks algorithm to serve the purpose. These are capable of predicting new observations on specific variables from previous observations on the same or other variables after executing a process of so called learning from existing training data Haykin 1998 .The results indicate that the performance of KNN method when compared with the medical diagnosis system was found to be 91 . This system can be used to assist medical programs especially in geographically remote areas where expert human diagnosis not possible with an advantage of minimal expenses and faster results.
