Study Notes

Biological Neurons and Artificial Neural Networks (ANNs)

The main function of the Biological Neuron is to process and transmit information.
Each neuron in the human brain is connected to other neurons through an average of 7,000 synapses.
The two fundamental components of biological neural networks are neurons and synapses.

Artificial Neural Networks (ANNs)

The main purpose of Artificial Neural Networks (ANNs) is to recognize patterns in data and make decisions based on that data.
ANNs are particularly useful for recognizing faces or hand-written text, which are difficult tasks due to the complexity and variability of the data.
A well-trained ANN has the ability to learn from experience and make accurate predictions or decisions.

Neural Network Components

In a neural network, each neuron is a processing unit that receives input, performs a computation, and sends the output to other neurons.
The strength of each input at each neuron is modified by weights.
The activity of the hidden units in a neural network depends on the inputs and weights.

Neuron Model

The function of the squashing or activation function in a neuron model is to introduce non-linearity into the output of the neuron.
The activation function determines the output of a neuron based on the input it receives.

Neural Computing

An artificial neural network (ANN) requires a large amount of data and computing power for neural computing.
ANNs learn from experience through a process of iterative refinement, where the weights and biases are adjusted based on the error between the predicted output and the actual output.
The raw information fed into a neural network is called input data.
In a neural network, neurons are arranged in layers, with each layer processing the input data in a hierarchical manner.
