A neural network is designed on the concept of deep learning. Deep learning is the subconcept of Machine learning Technology. All the algorithms are getting trained on the basis of the structure of the human brain. A neural network is defined as the, it takes the data and trains itself in order to identify the patterns and will predict the output for the new set of the data.
The below diagram represents a neural network. It is the layers of the neurons. The neural networks are also called the core processing units in a network. we have a three-layer. The first layer takes the input and helps to predict the final output.
The layers between the input layer and the output layer are called the Hidden layers. The artificial neural network works alike the similar functioning in the human brain. In the hidden layers where most of the computation process is get done. In the below figure neurons of one layer get connected to the neurons of the other layer. The connection between one layer to the other layer is called the channels. Each channel is assigned a numerical value to it. The numerical value can be called a weight.
The input we are given should get multiplied with their corresponding weight and the output of these layers will be given as input to the hidden layer. Each neuron will have a weight assigned to it, we have these as the bias, later it is added to its input sum. Now, this is passed through a function called the threshold function. The threshold function is also called the activation function.
The output to this activation function determines if a particular neuron is get activated or not. If the neuron is active it transmits the data to the neurons of the over that present over the channel. This is the process where the data is get propagated through the network. This type of propagation is called forward propagation. Coming to the output layer, the neuron which has the highest value will determine the output. To predict whether the output is correct or wrong, the network should be trained.

During the training process, along with the input, the network has the output given to it. Now, this output is then compared to the actual output to find the error in the output prediction. The magnitude that is given tells the accuracy of how wrong the output.
The sign simply indicates, whether our predicted values are higher or lower than we expected. After the error gets predicted, this information is transferred back to the network. The transfer of information to the back is called backpropagation. Considering the information we sent backward, the weights are getting adjusted.
The forward and backward propagation is performed based on the multiple inputs. This process is continuously done until the network can predict the shapes correctly. The neural networks can take much time to train the algorithms. Simply, the models we use in deep learning are called the artificial neural network. Artificial neural networks work as computing systems.
These are inspired by the structure of the human brain. All these collected units are called artificial neurons. The connection between these neurons can transmit the signal from one neuron to the other neuron. The receiving neuron can process the signals, these signals are connected to it. All the different layers will perform the different transformations in a neural network.
The signals get to travel from the input layer to the hidden layers and to the output layer. We can illustrate through different structural types in the neural network. The one we discussed earlier is a simple neural network with hidden layers in it.

There are again different types of artificial neural networks. Single-layer feed-forward network, multilayer perceptron, a multilayer feedforward network, and feedback artificial neural network. The below figure represents the single-layer feed-forward network. It is the simple structure for the artificial neural network, it has only two layers, the input layer, and the output layer.
The input layer receives all the inputs and stores them in the different neurons in the input layer. It processes in the input layer and gives the information to the output layer. In a single layer, each neuron is get connected to the neurons of the output layer and vice versa by allocating specific weights to each neuron. The weights are also called the synaptic weights.
The Next type of artificial neural network is a multilayer feedforward network. The multilayer feed-forward consists of hidden layers, in which it processes the information. The hidden layers make it computationally more strong. The below figure represents the artificial neural network. similar to the previous figure, the first layer is called the input layer.

The layer connected to the input layer is called the hidden layer. The layer that is connected to the other side of the hidden layer is called the output layer. In multilayer, all the neurons are get connected to all the neurons on the other layer by allocating specific synaptic weights to each neuron in a layer.
The next layer is called the multilayer perceptron. The multilayer perceptron consists of two or more layers. The below figure 1.4 represents the multilayer perceptron, similar to all layers, the multilayer perceptron has an input layer hidden layer and the output layer.
There can be many more hidden layers compare to the previous layers like the single layer and the multi feed-forward neural network. These multiple layers are used to classify the nonlinearly separable data.
The nonlinear separable means the linear separation of the data by mapping the data to the high dimensional space. It is also the fully connected neurons where all the neurons are get connected to each other in another layer of the neurons by using the nonlinear activation function.
The below figure represents the multilayer perceptron diagram consists of one or more layers and irrespective of the input and the output layer.
The Other layer is called the feedback artificial neural network, the difference between the other layers and the feedback artificial neural network is to adjust the parameters, the below figure represents the feedback artificial neural network, the feedback checks if any error present in the neural network, if it finds the error in it, then all the parameters are getting changed.
This process is called a feedback artificial neural network. The main purpose is to adjust the parameters in the neural network by minimizing the errors. There are many prime applications that we are using for neural networks, facial recognization, the best example for facial recognization is all the cameras that we are using in our smartphones, nowadays every smartphone has a feature to detect the face of the person to unlock their respective smartphones. some of the smartphones can estimate the age of a person by just featuring their face.

It differentiates the face from our background and identifies the spots and lines on the person’s face for the identity. Another application is forecasting, these neural networks can understand the patterns and detects the possible outcomes, and tells the possibility of rainfall, stock prices with high accuracy.
One more application is music composition, the neural networks can learn patterns and music and get trained themselves. There are again many more like in speech recognization, the health care department, and marketing. All the neural networks are used in a different set of domains.

It is also called the functional of deep learning, the artificial neural networks have been used to copy the behavior of the human brain to solve many complex problems. The artificial neural network uses the part of the concept of deep learning, which is the part of machine learning, which is the part of the huge Technology called machine learning.
All these concepts are interconnected fields, it provides the set of the algorithms and trains those algorithms to solve complex problems. The deep learning concept trains the artificial neural network, to works similar to the human brain neural networks.
It starts functioning when some of the input data is given to the input layer of the neural network. The given data gets processed by the different layers in the perceptron for providing the desired output. To understand the process in detail, let us consider the set of mangoes that has both spoiled and unspoiled fruits.

Now the neural network should identify all the spoiled fruits and unspoiled fruits and should divide them into two classes. Now we should train our neural networks. These dive the fruit image into different pixels and converted it into the form of the matrices into the form of the architectural neural network.
All these neurons are get connected to each other neuron in different layers to transform the information from one neuron to the other neuron, the perceptrons in the neural network take the inputs and processes the output by passing them on the different layers, now the output layer contains the two different classes that contain spoiled and unspoiled fruits separately.
