1. The primary purpose of the passage is to
Para 1: What are Artificial Neural networks (ANN) + their parts
Para 2: How ANN works
A) describe artificial neural networks
This was a tough contender but C gives a more detailed descriptionB) contrast artificial neural networks with neural networks found in brains
Incorrect. No contrast madeC) illustrate how to build an artificial neural network
Incorrect. We're not told how to make itD) argue for the wider adoption of artificial neural networks
Incorrect. There is no argumentE) outline the different units of an artificial neural network and their roles in producing intelligence
Correct. Gives correct description of the passage2 It can be inferred from the passage that real neural networks
A) are to be considered superior to artificial neural networks
Incorrect. Not explicitly said in or implied by the passageB) consist of input, hidden, and output units
Incorrect. this is mentioned w.r.t artificialC) inspired the development of artificial neural networks
Correct. Since ANN simulates real neural networks, we can infer that ANN is inspired from Real Neural NetworksD) are more capable of recognizing patterns than artificial neural networks
Incorrect. Nothing of this sort can be inferredE) will someday become obsolete
Incorrect. Nothing of this sort can be inferred3. According to the passage, which of the following best represents the optimal flow of information through an artificial neural network?
This is mentioned in the 2nd para
Quote:
Information is passed to the input units, which trigger the hidden units. The hidden units are activated and the sum of the inputs it receives triggers the next unit to fire if the sum exceeds a certain threshold. By giving the output units a model to compare the result of the learning process to, the artificial neural network can learn where to place more weight in order to make the result of the output unit more closely resemble that of the model.
A) A model is shown to the input units which pass information to the output units which describe the model.
Incorrect. Information is passed to input units B) Information is fed to the input units which activate the hidden units which then change the input units to more closely resemble the model.
Incorrect. Input units are themselves not changed.C) The input units receive information to give to the hidden units which then forward information to the output units to compare against a model.
Correct. The series matches that shown in the highlighted part of quoteD) A model is shown to the input units which then attempt to recreate the model using different information.
Incorrect. Doesn't conform to the steps in the quoteE) The input units are activated by information fed to them via the output units which analyze a model and improve the information before handing it to the input units.
Incorrect. output units give results and do not pass information to input units
