CSCI-567 (fall 2007)

Homework 1 clarifications

All,

There have been some good questions regarding homework 1.  I wanted to communicate two clarifications to all of you:

1) Question 3B: It should read which is more specific:
	1-of-3 of {x1,x2,x4}
	2-of-4 of {x1,x2,x4,x5}

2) Question 5 --- if you use the perceptron algorithms shown on slides
19 and 20 in lecture2b.pdf, then you should consider the "if" statement to read:
	If(y_i * u_i <= 0)
This is in accordance to the gradient as shown on slide 17

3) Question 5 --- if you use the perceptron algorithms shown on slides
19 and 20 in lecture2b.pdf, then you should reset the gradiant to all 0's
   right after the "repeat" keyword.
