'''Artificial Neural Networks (ANN)''' (or more commonly known as '''Artificial Intelligence''') have become the most prominent research topic in modern computer science as we are entering the golden age of A.I., the use of machine learning and deep learning have become a common use for practical and intensive purposes.

'''Artificial Neural Networks''' are simple to complex series of data representation within a network that changes according the certain algorithms applied with the phases of the structure. The artificial neural network was initially inspired by biological neural networks and their functions of processing input and output data. Within A.I. the biological 'neurons' are represented as '''nodes''' within an ANN which are systems of interconnected points exchanging messages between one another and have numeric weights/constraints applied to them that allow these neural nets to adapt/alter input data thus creating the Artificial Intelligence's ability to "learn".
which are systems of interconnected points exchanging messages between one another and have numeric weights/constraints applied to them that allow these neural nets to adapt/alter input data thus creating the Artificial Intelligence's ability to 'learn'.
These nodes within the network can be thought of as phases within a neural net where data can be processed, stored or gathered. Information can flow readily throughout these nodes and can be modified by the algorithms the architect chooses to weigh on them.
There are a variety of algorithms available for use within neural networks and these can be interchangeably placed depending on the structure of the ANN and what the intended use/purpose is.

Machine Learning Algorithms are the backbone of Artificial Neural Networks as they are what allow the neural network to created 'learned' material through the constraints placed on the data by the algorithms.

There are various types of Machine Learning Algorithms which are used to comprise neural nets. The main include "Supervised Learning", "Unsupervised" and "Semisupervised".
There are various types of Machine Learning Algorithms which are used to comprise neural nets. The main include '''Supervised Learning''', '''Unsupervised''' and '''Semi-supervised'''.
'''Supervised''' machine learning algorithms consists of target/outcome variables (dependent variables) which are predicted from a given set of predictors (independent variables). This means that by using these sets of variables, we generate a function that maps inputs to desired outputs. In other words, we determine predictable output data representation.
The most common types of '''Supervised Learning''' algorithms include:
*Regression
*Random Forest
*KNN
*Logistic Regression

Regression algorithms are forms of analysis which create predictive modeling techniques within Supervised and Semi-Supervised Learning. This analysis estimates the relationship between the dependent variable(s) (target[s]) and independent variable(s) (predictor[s]).
Although there are many forms of regression algorithms,the two main types of regression techniques used within Machine Learning:
Regression

*''' Linear Regression'''

'''Semi-Supervised''' or '''Reinforcement Learning''' Algorithms is when the machine is trained to make specific decisions and are exposed to environments where it trains itself continually by using trial and error. These machine learning algorithms learn from past experience and try to capture the best possible knowledge to make accurate business decisions.
An example of "Semi-Supervised" Learning includes:
An example of '''Semi-Supervised''' Learning includes:
Markov Decision Process
Markov Decision Process
"Unsupervised Learning" Algorithms are algorithms that are applied within a neural network when there is no target or outcome variable to predict/estimated. An example use of these algorithms could be used for clustering population in different groups.
