The 1989 Math Contest in Modeling posed The Midge Classification Problem (attached). Given that this is an artificial intelligence course, how would you develop an artificial intelligence with which you could answer questions 1. and 2.? Don't solve this with statistical techniques. Your artificial intelligence must exhibit attributes of artificial intelligence in Chapter 1 of our text. 1. Given a midge that you know is species Af or Apf, how would you go about classifying it?

2. Apply your method to three specimens with (antenna, wing) lengths(1.24, 1.80), (1.28, 1.84), (1.40, 2.04). Your artificial intelligence must be specified as a step-by-step procedure for solving this specific problem with finite amounts of resources (algorithm). Each step must be executable by a human using pencil and paper. You must, therefore, carry out your artificial intelligence algorithm for midge classification. Use the data in the graph to train your artificial intelligence. Then exercise your artificial intelligence using the three specimens in 2. above.

3. Assume that species Af is a valuable pollinator and species Apf is a carrier of a debilitating disease. Would you modify your classification scheme and if so, how? You must hand in the following items: A) A description of your artificial intelligence and what attributes in Chapter 1 it exhibits. B) An artificial intelligence algorithm C) Record of training your artificial intelligence with the data in the graph D) Record of the decision(s) your artificial intelligence made with the data in 2.

1989: The Midge Classification Problem Two species of midges, Af and Apf, have been identified by biologists Grogan and Wirth [1981] on the basis of antenna and wing length. (See Figure 1.) Each of nine Af midges is denoted by ", and each of six Apf midges is denoted by "o". It is important to be able to classify a specimen as Af or Apf, given the antenna and wing length. 1. Given a midge that you know is species Af or Apf, how would you go about classifying it? Apply your method to three specimens with (antenna, wing) lengths 3. Assume that species Af is a valuable pollinator and species Apf is a carrier of a debilitating disease. Would you modify your classification scheme and if so, how?
