This homework assignment is due before class starts on Tuesday, January 25. Your solutions should be explained in complete sentences such that your classmates will understand the solution (and can verify your proofs are correct) even if they have not solved the problems themselves.

  1. HW Polices.

    1. Type your HW (in word, latex, text file, etc.) and send to me by email.

    2. Do NOT share electronically. You must type your own solutions. You can discuss the problems with each other, but you may only discuss them. You may not write out solutions together.

    3. You MAY NOT search the Internet, textbooks, etc. for solutions to the problems. The following are the ONLY sources of information that you may use in solving the problems: the textbook for this course and assigned reading, and wikipedia articles on basic math/probability/CS/etc.. You may discuss the problems with each other and with myself, but must obey the previous item in doing so.

      If you do find the solution in one of these sources, you still MUST cite the source in your document.

      You may use NOTHING ELSE that is online or other textbooks.

    4. You MAY NOT copy word-for-word from any source, even the sourcesyou are allowed to consult. If you feel it is necessary, you should put the quotation in quotes and provide a reference/citation.

  2. (-3 points if left blank) List who you collaborated with on this assignment, "none" if none.

  3. (5 Points, assigned by Luke) This question has three parts, which can all be seen here. A list of the different junctions from the book are here.

  4. (5 Points, assigned by Kunal) Describe the following terms briefly: Neural Nets, Neurons, Synapses, Sigmoidal Functions, Learning of Neural Nets.

    Refer to the last paragraph on page 245, "This particular network had 40 ... medial layer instead of 15!". Give a reason why the performance becomes worse with increasing the number of neurons in medial layers.
