Artificial Neural Network (DL_ANN)

This function creates and uses a model consisting of layers of interconnected nodes (neurons) that process input data and produce output predictions.

An artificial neural network (ANN) is a type of machine learning model inspired by the structure and function of biological neurons in the human brain. It consists of layers of interconnected nodes (neurons) that process input data and produce output predictions. Each neuron takes in one or more inputs, applies a mathematical function to them, and passes the result to the next layer of neurons. By adjusting the weights and biases of the connections between neurons during training, the network can learn to make accurate predictions on new data. ANNs are used for a wide variety of tasks, including image and speech recognition, natural language processing, and predictive modeling.
