Deep Learning Techniques | An Overview

 Deep Learning is a method of data mining using deep neural network architectures, which in recent years have become increasingly relevant in many typos in artificial intelligence and machine learning algorithms. Deep learning technologies are predicted to affect your life soon. Deep learning helps us to teach machines how to do complex tasks without programming them directly.

Let’s learn about the methods to solve a range of problems by deep learning:

Fully connected feedforward:

Fully connected feedforward neural networks are the traditional network architecture for most simple applications of neural networks. Fully connected means that in the next layer, each neuron is linked to another neuron. And feedforward means that neurons in any previous layer are only connected in a subsequent layer to the neurons. An activation function of each neuron in a neural network affects the output of a neuron given its input. These functions are as follows:

Linear Function: The input is simply multiplied by a constant value in a straight line.

Non-Linear Function: Under this, there are 3 other functions like Sigmoid function, Hyperbolic tangent function, Rectified linear unit function.

Each type of function has advantages and disadvantages so that we use them in different layers of a deep neural network depending on the issue that each has. Non-linearity is the framework for complex functions in deep neural networks.

Generative Adversarial Networks

The GN is a combination of two deep learning neural networks: the Generator Network and the Discriminator Network. The Network generates synthetic data and the Network of the Discriminators attempts to detect whether the information it sees is genuine or fake. These two networks are competitors, both of which compete to defeat each other. The Generator tries not to differentiate artificial data from real data and the Discriminator aims to steadily enhance the identification of fake data.

Recurrent Neural Network

The recurrent neural network (RNN) can function effectively in data sequences with variable input lengths, unlike feedforward neural networks.

This means that RNNs use their prior state of knowledge as an input for their current prediction, that we can replay for an indefinite number of steps to allow the network to disperse information over the time it is cached. It is basically like having a short-term memory for a neural network. This feature helps RNNs to function extremely effectively with time-long data sequences.

Convolutional Neural Networks

CNN is a type of deep neural network architecture designed for particular tasks like the classification of images. In the visual cortex of the animal brain, CNNs are influenced by the organization. As a result, they give some very interesting characteristics that are useful to process such data types such as images, audio, and video.

The input layer consists of a CNN. This input is usually a 2-dimensional neuron array, which matches the pixels of a frame, except for simple image processing. It also requires an output layer that is normally a one-dimensional collection of output neurons. CNN uses a mixture of sparingly connected convolution layers that process images on the input. They often include sampling layers called pooling layers, which further decrease the number of neurons required in subsequent network layers. Finally, CNN’s normally have one or more layers that are completely connected to the output level in order to link the pooling layer.

Deep Reinforcement Learning

Reinforcement learning ensures that an agent communicates with an environment. In the environment, the agent attempts to achieve some sort of objective. The environment has a situation that the agent will observe. The agent has actions that can affect the state of the environment, and when they complete some form of purpose, he or she receives incentive signals. The agent’s goal is to learn how to communicate with their surroundings so that they can accomplish their objectives.
