Advantages and disadvantages of Artificial Neural NetworkAdvantages:· A neural network can perform tasks that a linear program cannot.· When an element of the neural network fails, it can continue without any problem by their parallel nature.· A neural network learns and does not need to be reprogrammed.· It can be implemented in any application and without any problem.Disadvantages:· The neural network needs training to operate.· The architecture of a neural network is different from the architecture of microprocessors therefore needs to be emulated.· Requires high processing time for large neural networks.

The Radial Basis Function Neural Network Kernel is frequently utilised because of how much it resembles the K-Nearest Neighborhood Algorithms. Radial Basis Function Neural Network Kernel Support Vector Machines have K-NN advantages and address the memory complex problem by requiring the coordinates to be stored during training rather than the entire dataset.

A basic neuron in a neural network is a computational unit that takes input values, applies weights to them, sums them up, adds a bias, and then passes the result through an activation function to produce an output. This output is then passed to other neurons or to the network's output layer.

the neural networks need training to operate. the architecture of a neural network is different from the architecture of microprocessor therefore needs to be emulated.
In a neural network, an epoch refers to one complete pass of the entire training dataset through the neural network. During one epoch, the model updates its weights based on the error calculated from the predictions compared to the actual target values. Multiple epochs are typically required to train a neural network effectively.
The formula to calculate the critical number of layers in a neural network is given by 2^(1/L), where L is the number of layers. This formula helps determine the size of a neural network needed to approximate a given function.
