Introduction
Neural networks are a set of algorithms, modeled loosely after the human brain, that are designed to recognize patterns. They interpret sensory data through a kind of machine perception, labeling or clustering raw input. The patterns they recognize are numerical, contained in vectors into which all real-world data must be translated. Artificial neural networks (ANNs) face the same task as biological brains: to combine inputs into meaningful outputs. These layers are densely interconnected with one another but not with nodes within the same layer. Nodes between layers are called [edges](https://en.wikipedia.org/wiki/Edge_(graph_theory)).

The original neural networks were inspired by biological systems such as neurons and synapses; however, they can be used with any type of signal processing problem where it's necessary to identify and analyze patterns in data (for example: speech recognition).

The patterns they recognize are numerical, contained in vectors, into which all real-world data, be it images, sound, text or time series, must be translated.
Neural networks are a class of machine learning algorithms that mimic the structure of neurons in the human brain. They’re trained to perform complex operations by processing data like images and sound, which are then interpreted as patterns or numbers.
The pattern recognition process begins with an algorithm called a training set; this represents examples of what you want your neural network to look for (e.g., “Is there an object in this image?”). The training set is fed into your neural network—a group of interconnected computers that work together as one unit—and its output determines how good it is at recognizing specific patterns from it (e.g., “Yes! There is!”). As these outputs become more accurate over time, you can use them for future tasks based on their accuracy levels: if your neural network says yes 95% percent of the time when asked whether something exists within an image, then let's say we want our robot vacuum cleaner robot vacuum cleaner robot vacuum cleaner robot...

In ANNs, we use a set of interconnected “neurons” that are used to approximate functions. The neurons are connected together by weighted connections that function like synapses in our brains. Each neuron takes in input data and performs an operation on it (e.g., multiplying two numbers together), then sends its output through another layer of neurons until it reaches the final layer where a decision is made about what to do next based on whatever rule you've trained your ANN with before hand.
These layers are densely interconnected with one another but not with nodes within the same layer. Nodes between layers are called [edges](https://en.wikipedia.org/wiki/Edge_(graph_theory)).
Neural networks are composed of layers, where each layer consists of nodes. Nodes in the same layer are connected with edges and nodes in different layers are connected by edges.
In this kind of network, there are neurons at each node that receive input from other neurons and provide output to them. The connection between any pair of neurons determines whether an action is performed on a given set of data (for example, if A receives input from B). In other words:
Input->Neuron/Layer 1->Output/Node 2->Input->Neuron/Layer 2 ->Output//etc..
A neural network does not work like your brain does - it works indisputably differently from the way we think the brain works - but it functions by approximating functions and thus mimics some aspects of human behaviour under imperfect conditions or incomplete information (i.e., too little training data).

In other words, a neural network is an algorithm that learns from input data and outputs a result based on that input data. It has been found to be capable of learning complex tasks in fields such as computer vision and natural language processing (NLP).

Conclusion
So, there are some pretty cool applications of neural networks. They're not just for fun. They're really useful in a lot of different kinds of problems, and we can't afford to ignore them anymore.
