Neural Network

What is a neural network

• A network of biological neurons in the brain.

• computational model inspired by the human brain composed of interconnected nodes.

• A network of interconnected computers.

Why do we need neural networks?

• to solve tasks like machine vision & natural language processing

• to apply heuristic search methods to find solutions of problem

• to make smart human interactive & user friendly system

• all of the mentioned

The fundamental unit of neural network is ______

• brain

• nucleus

• neuron

• axon

What is the primary function of dendrites in a neuron

• Transmitting signal away from the cell body

• Transfer information to neuron

• Generating action potentials

• Providing structural support to the neuron

Why can't we design a perfect neural network?

• full operation is still not known of biological neural

• number of neuron is itself not precisely known

• number of interconnection is very large & complex

• all of the mentioned

In a feedforward neural network, information travels in which direction?

• Forward only

• Backward only

• Both forward and backward

• Randomly

What is the purpose of the activation function in a neural network?

• To initialize weights

• To compute the cost function

• To introduce non-linearity

• To connect neurons

What is backpropagation used for in neural networks?

• Initializing the network

• Forward propagation

• Training and updating weights

• Testing the network

In an ANN, what does the term 'bias' refer to?

• A measure of model complexity

• An offset term added to the weighted sum in each neuron

• The learning rate of the network

• The number of layers in the network

How many layers are typically found in a Multilayer Neural Network?

• one

• two

• three

• more than three
