What is Deep Learning? How is It Redesigning the Tech World?

Deep learning is the sub-branch of machine learning, which in turn is the sub-branch of artificial intelligence. It trains the artificial neural networks to learn the data automatically from the previous experience and improve the quality of the content every time with the diverse experience. It is the most trending topic in the technical world; therefore, we will discuss it from scratch.

Today, we will learn the basic concepts of deep learning and how the technical world is rapidly changing because of the innovations in deep learning. We will discuss the introduction and history of deep learning and how it has evolved with time. After that, we will discuss some important fields where the technical departments are getting more efficient results by integrating the techniques of deep learning into their work. We will discuss different departments that use deep learning to improve the user experience and create new techniques with the help of user behavior analysis. So let’s start with the introduction of deep learning.

What is Deep Learning?

Deep learning is a complex network of artificial neural networks. Just like the human brain learns from the network of neurons, deep learning trains, learns, and understands through the vast interconnected network. This network has three types of layers:

1. Input layer
2. Hidden layer
3. Output layer

The input layer is the entry point of the data and in the hidden layers, the learning process is carried out. Once the calculations are performed on the data, the result is sent to the output layer. In interconnected networks, the output layer is connected to the input layer of the next deep learning network. The complexity and performance of the deep learning network depend on the number of hidden layers in it. As a result, these networks work on the classification of the data to predict the results by comparing and studying its behavior in different ways. The neurons in the neural network are arranged according to different weights and biases, and this is the basic structure through which the network learns from the calculations.

Evolution in Deep Learning

The work on deep learning started in the 1950s when artificial neurons were trained. It gave the confidence to work on deep learning because it was helpful in pattern recognition. After that, the work on this technique was stopped because of the technical limitations. In 1986, the backpropagation method was developed on the given data, and this opened new doors for the researchers to work more on deep learning. After that, many researchers were attracted to this technique because of the automation in the learning.

At that time, dealing with deep learning techniques was still challenging because of the limited research and the complex work with the computational algorithms. People were working with a single hidden layer, and the results were not satisfactory. Still, this was considered an important technique.

In the 2000s, powerful computers and larger datasets allowed researchers to work on these techniques at a faster rate, and it was the point where people were attracted toward deep learning. The convolutional neural network CNN gained fame in image recognition, and this was one of the most important steps toward the success of deep learning. Similarly, recurrent neural networks were useful in speech recognition and related tasks.

From the 2010s to the present, multiple techniques have been used in deep learning that are incorporated into different fields of science and technology. These are improving at a rapid rate and it is estimated that in the future, all businesses, technical fields, and even daily life will be improved with the help of deep learning techniques and algorithms.

Forward Propagation in Deep Learning

In the layers of deep learning networks, the nodes are the basic element that creates the connection between the networks. Each node takes the data from the previous one to perform more calculations and provide a more refined prediction and categorization of the data. The continuous progression of the data from one node to the next is called forward propagation.

Back Propagation in Deep Learning

Backpropagation in deep learning is an algorithm for extracting the required results from the data. In this, the errors are calculated on the output layer by comparing them with the real data. As a result, it propagates the error through the layer back and performs the required measure to get better results. It is an important algorithm in neural networks because it allows the network to perform complex tasks such as image recognition, natural language processing, machine translation, voice recognition, etc.

The illustration given above is the most basic and simple way to understand deep learning processes. Together, forward propagation and backpropagation allow the network to learn better at a faster rate. It is a complex process and requires the knowledge of multiple concepts if the reader wants to know all the basics and mechanisms of working deep learning networks. Overall, deep learning is a powerful network that is designed to learn from the data and classify it into different groups.
