A 3-input neuron is trained to output a zero when the input is 110 and a one when the input is 111. After generalization, the output will be zero when and only when the input is?


a000 or 110 or 011 or 101


b010 or 100 or 110 or 101


c000 or 010 or 110 or 100


d100 or 111 or 101 or 001



Which of the following is an application of NN (Neural Network)?


aSales forecasting


bData validation


cRisk management


dAll of the mentioned


View Answer All of the mentioned

The network that involves backward links from output to the input and hidden layers is called _________


aSelf organizing maps


bPerceptrons


cRecurrent neural network


dMulti layered perceptron



Having multiple perceptrons can actually solve the XOR problem satisfactorily: this is because each perceptron can partition off a linear part of the space itself, and they can then combine their results.


aTrue – this works always, and these multiple perceptrons learn to classify even complex problems


bFalse – perceptrons are mathematically incapable of solving linearly inseparable functions, no matter what you do


cTrue – perceptrons can do this but are unable to learn to do it – they have to be explicitly hand-coded


dFalse – just having a single perceptron is enough
