The web application displays the predicted results of our test data using the kNN Algorithm. The application was written in Java and the GUI was constructed in a JSP using CSS, JavaScript and DHTML. The actual calculations performed by the Java kNN class can be viewed seemlessly by clicking on a row arrow. As shown by the calculations, the Euclidean Distance formula was used to calcuate the distance between contineous attributes. A similarity matrix was used to calculate the distance between symbolic attributes.
