What does ANN stand for, and what is it inspired by?
Answer
ANN stands for Artificial Neural Network. It is a computing system inspired by the biological brain and its network of neurons.
Why are artificial neural networks used in AI?
Answer
Artificial neural networks are used because they can learn from data, recognize patterns, and make predictions. They are useful for tasks such as classification and regression.
Who invented the first artificial neural network, and when?
Answer
The first artificial neural network, called Perceptron, was invented in 1958 by psychologist Frank Rosenblatt. It was intended to model how the human brain processes visual data and learned to recogni…
What is a biological neuron?
Answer
A biological neuron is the basic functional unit of the nervous system. It receives, processes, and transmits electrical and chemical signals.
Name the four parts of a neuron.
Answer
A neuron has four parts: dendrites, soma, axon, and synapses.
What is the function of dendrites?
Answer
Dendrites are tree-like branches that receive information from other neurons. In an ANN, they correspond to the input layer.
What is the function of the soma?
Answer
The soma is the cell body of the neuron. It processes the information received from dendrites. In an ANN, it matches the idea of hidden layer processing.
What is the function of the axon?
Answer
The axon is the cable-like part of a neuron through which information is sent to the next neuron. In an ANN, it corresponds to the output layer.
