Artificial Neural Networks Quiz

What are neural networks?

• Systems with interconnected nodes that work in a similar way to the neurons in the human brain

• Systems with interconnected nodes that work in a similar way to the muscles in the human body

• Systems with interconnected nodes that work in a similar way to the cells in the human body

• Systems with interconnected nodes that work in a similar way to the organs in the human body

How do nodes in a neural network get activated?

• When there is insufficient input

• When there is no input

• When there is sufficient input

• When there is excessive input

What do the connections between artificial neurons in a neural network act like?

• Blood vessels

• Nerves

• Synapses

• Muscles

What happens to signals in a neural network as they move from one hidden layer to another?

• They are processed and transmitted

• They are ignored and discarded

• They are stored and saved

• They are multiplied and divided

What do neurons in a neural network do with input stimulus?

• Run mathematical calculations to determine if there is enough information

• Ignore the input stimulus

• Pass the input stimulus to the next neuron without any calculations

• Store the input stimulus for later use

What happens if the sum of data inputs in a neuron is more than a certain threshold value?

• The neuron becomes inactive

• The neuron 'fires' and activates the neurons it is connected to

• The neuron deletes the data inputs

• The neuron passes the data inputs to the next neuron

Where is data fed into a neural network?

• Output layer

• Hidden layers

• Input layer

• Activation function

What takes place in the hidden layers of a neural network?

• Data processing through a system of weighted connections

• Data storage for future use

• Data deletion

• Data transmission to the output layer

What do nodes in the hidden layer of a neural network do with data from the input layer?

• Combine data with a set of coefficients and assign appropriate weights to inputs

• Ignore the data from the input layer

• Pass the data to the output layer without any processing

• Store the data for later use

What happens to the input-weight products in a neural network?

• They are ignored and discarded

• They are summed up

• They are multiplied and divided

• They are stored and saved
