2. You are working as an assistant biologist to Charles Darwin on the Beagle voyage. You are at the Galapagos Islands, and you have just discovered a new animal that has not yet been classified. Mr. Darwin has asked you to classify the animal using a nearest neighbor approach, and he has supplied you the following dataset of already classified animals. ID CLASS BIRTHS LIVE YOUNG LAYS EGGS FEEDS OFFSPRING OWN MILK WARM- BLOODED COLD- BLOODED HAS HAIR HAS FEATHERS LAND AND WATER BASED 1 2 3 4 true false true false false true false true false true false true false true true false true false false false true false truc true false true false false false false true mammal amphibian mammal bird true The descriptive features of the mysterious newly discovered animal are as follows: ID BIRTHS LIVE YOUNG LAYS EGGS FEEDS OFFSPRING OWN MILK WARM- BLOODED COLD- BLOODED CLASS LAND AND WATER BASED HAS HAIR HAS FEATHERS Query alse true false false false true false false a. A good measure of distance between two instances with categorical features is the overlap metric (also known as the hamming distance), which simply counts the number of descriptive features that have different values. Using this measure of distance, compute the distances between the mystery animal and each of the animals in the animal dataset. b. If you used a 1-NN model, what class would be assigned to the mystery animal? c. If you used a 4-NN model, what class would be assigned to the mystery animal? Would this be a good value for k for this dataset
