d) All of the mentioned
View Answer
Answer: d
Explanation: None.
1. Why is the XOR problem exceptionally interesting to neural network researchers?
a) Because it can be expressed in a way that allows you to use a neural network
b) Because it is complex binary operation that cannot be solved using neural networks
c) Because it can be solved by a single layer perceptron
d) Because it is the simplest linearly inseparable problem that exists.
Answer: d
Explanation: None.
2. What is back propagation?
a) It is another name given to the curvy function in the perceptron
b) It is the transmission of error back through the network to adjust the inputs
c) It is the transmission of error back through the network to allow weights to be adjusted so that the network
can learn
d) None of the mentioned
View Answer
Answer: c
Explanation: Back propagation is the transmission of error back through the network to allow weights to be
adjusted so that the network can learn.
3. Why are linearly separable problems of interest of neural network researchers?
a) Because they are the only class of problem that network can solve successfully
b) Because they are the only class of problem that Perceptron can solve successfully
c) Because they are the only mathematical functions that are continue
d) Because they are the only mathematical functions you can draw
View Answer
, Answer: b
Explanation: Linearly separable problems of interest of neural network researchers because they are the only
class of problem that Perceptron can solve successfully.
