Unformatted text preview: _ wT=_______ If not, why not? 2. Can a perceptron capture inequalities: given two real-valued inputs A and B, can the perceptron output 1 if A<B and 0 otherwise? If yes give weights: wA=_______ wB=_______ wT=_______ If not, why not? 3. You wonder about the real-valued function A=B within epsilon E, that is, with three inputs, A, B, and and E, can a perceptron capture whether |A-B| < E? If yes give weights: wA=_______ wB=_______ wE=_______ wT=_______ If not, why not? 7 4. The questions in part A have asked for solutions using a threshold decision function. Do the first round of training for A→B with a sigmoid decision function. Let the learning rate=1. A B T wA 0 0 -1 0 1 -1 1 0 -1 1 1 -1 wB wT 0 0 ∑ 1 y y* 1 1 0 1 The sigmoid decision function: y = 1/(1+e-x): 5. Which of the following is true about a perceptron when we use a sigmoid instead of a threshold? A. The perceptron can learn XOR B. The perceptron can no longer learn all linear classification boundaries C. The perceptron will learn A→B in fewer t...
