Suppose we have height, weight and T-shirt size of some customers, and we need to predict the T-shirt size of a new customer given only his height and weight. The Data includes height, weight and T-shirt size information is shown in the next slide. New customer named 'Mohsen' has height 161 cm and weight 61 kg. • The idea of using distance measure is to find the distance (similarity) between new sample and training cases, and then finds the 6-closest customers to new customer in terms of height and weight. xcel file Height (in cms) Weight (in kgs) 158 58 158 158 160 160 163 163 160 163 165 165 165 168 168 168 170 170 170 59 63 59 60 60 61 64 64 61 62 65 62 63 66 63 64 68 T Shirt Size M M M M M M M L L L L L L L L L L L HEIGHT (IN CMS) 172 170 168 166 164 162 160 158 156 56 58 ■ 60 62 WEIGHT (IN KGS) 64 66 68 22 70 23 M L
