Artificial Intelligence is one of the burning topics in today’s world and deep learning is the subset of machine learning in artificial intelligence. 


Deep Learning is continuously amusing us with its modern possibilities like self-driving cars, fraud detection, and many more.


Earlier we never imagined the things which are possible today and now we cannot even imagine a day without using it. Thus, in this blog, we are going to discuss this very interesting topic ‘Deep Learning’ in much more detail.


Deep Learning is at the beginning of what machines can do and developers and business leaders totally need to comprehend what it is and how it functions.


Deep learning models are sufficiently competent to focus on the exact features themselves by requiring a little direction from the programmer and are useful in taking care of the issue of dimensionality. Therefore, deep learning algorithms are used, particularly when we have a vast number of inputs and outputs.


So, moving forward let us further understand in detail several aspects of deep learning!


Why is it called Deep Learning?


Deep learning is an artificial intelligence work that mirrors the activities of the human brain in preparing information and making signs for use in decision making. It is also called deep neural learning or deep neural network.


It is a kind of machine learning that prepares a computer to perform human-like errands, for example, perceiving speech, distinguishing pictures, or making forecasts.


Rather than arranging information to go through predefined conditions, deep learning sets up essential boundaries about the information and trains the computer to learn on its own by perceiving designs using numerous layers of processing.


Deep learning has networks worthy of learning unsupervised from information that is unstructured or unlabeled. In simple language, deep learning is a type of algorithm that appears to work certainly well for anticipating things. 


The working of deep learning includes training the data and learning from past experiences. It is a promising method that makes it conceivable to teach computers something. This piece of machine learning imitates a human neural network.


This artificial neural network saves us time since it keeps individuals from performing monotonous activities and this procedure diminishes the risk of human blunder and hence has total added esteem.




  • The deep learning architecture is flexible to be fitted to new troubles in the future.

  • It has the proficiency to develop new features from the limited convenient training data sets.




  • Due to complicated data models, it is very expensive to train.

  • It is tough to adopt by less skilled people as there is no basic theory to teach you in choosing the correct deep learning tools.



How does it work?


Deep learning works on the concept of repeated teaching. It trains the computer so that it can understand a particular pattern and also identifies a picture or voice. After recognizing, the computer can automatically catch that word or voice.


This way of learning is not much different from how we humans learn. While we were kids we also learned to say a word by listening to things around us. This is how we learned and now deep learning is using this formula to teach computers.

Importance of Deep Learning


  • Deep learning is very much important as it makes our task accurate and fast.

  • The capacity to process large numbers of details makes deep learning very strong when handling with undeveloped data.

  • Hence, computer vision is an immense example of a task that deep learning has altered into something logical for business applications.

  • Deep learning makes it possible to identify faces on Facebook.


Applications of Deep Learning


There are several applications of deep learning across industries. Here, we will discuss some of them in detail.


  1. Self Driving Cars


Self-driving cars are one of the hottest areas of study and business for the tech demons and deep learning is the power that is rejuvenating self-ruling driving. 


Read the blog on How Tesla is making use of Artificial Intelligence in its operations?


Several sets of data are grazed to the system to assemble a model, to prepare the machines to learn, and afterwards test the outcomes in a protected climate.


At Pittsburg, there is an Uber Artificial Intelligence Labs which isn't just operating on preparing driverless vehicles humdrum but also incorporating many creative things. For example, they are trying to make food delivery possible by driverless vehicles.


Data from cameras, geo-mapping, sensors are assisting in creating brief and sophisticated models to guide through traffic, identify ways, and real-time components such as traffic volume and road stoppages.


Also, the significant worry for self-driving car developers is dealing with uncommon situations. A customary pattern of testing and execution regular to deep learning algorithms is guaranteeing safe driving with increasingly more openness to a great many situations.


So, we can assume that in the future deep learning will definitely give many more such intelligent technologies.

Displaying deep learning applications like self-driving cars, virtual recognition, virtual assistant, NLP, fraud detection, and entertainment.

Deep Learning applications

  1. Virtual Assistants


Virtual Assistants are one of the very popular applications of deep learning. We all use virtual assistants like Alexa, Siri, Google Assistant in our day to day life.


Every communication with these assistants provides them with a chance to study your voice and emphasize, consequently giving you an optional human interaction experience.


Thus, virtual assistants use deep learning to find out more about their subjects going from your dine-out inclinations to your most visited spots or your main tunes. They figure out how to comprehend your orders by assessing common human language to execute them.


Virtual assistants are actually available at your beck-and-call as they can do everything from getting things done to auto-reacting to your particular calls to planning assignments among you and your colleagues.


Another power virtual assistants are invested in is interpreting your speech to message, make notes for you, and book arrangements.


With deep learning applications like text generation and record synopses, virtual assistants can help you in making or sending proper email duplicates also.



  1. Virtual Recognition


We always face a problem when we have plenty of old pictures but we want some selected images. So, here we faced problems and wasted time and energy in selecting pictures.


So, here comes deep learning that helps in arranging pictures dependent on areas identified in photos, faces, a mix of individuals, or as per occasions, dates, and so forth.


Looking for a specific photograph from a library (suppose a dataset as extensive as Google's image library) requires state-of-the-art visual recognition systems consisting of a few layers from fundamental to advanced to recognize elements.


Large scale image visual recognition through the deep neural networks are improving development in this section of advanced media management by using convolutional neural networks, Tensorflow, and Python broadly.



  1. Natural Language Processing


NLP is described as the natural manipulation of normal languages, like speech and text, by software and it is the one that aids in perfect communication between human language and computer language.


The area of natural language processing is one of the most crucial and practical applications of deep learning. Through Deep Learning, NLP is attempting to accomplish something very similar by preparing machines to get linguistic nuances and frame suitable reactions.

Dealing with questions, classifying text, Twitter analysis, or sentiment analysis at a more extensive level are altogether subsets of NLP where deep learning is acquiring propulsion.



  1. Entertainment (Netflix, sports highlights, VEVO, etc)


Netflix and Amazon are improving their deep learning capacities to give a customized insight to their viewers by making their personas figuring in show inclinations, time to access, history, and so forth to prescribe shows that are of getting a kick out of the chance to a specific watcher.


Deep Learning AI is changing the filmmaking cycle as cameras figure out how to examine human non-verbal communication to soak up virtual characters.


Content altering and auto-content creation are now a reality because of deep learning and its commitment to face and pattern recognition.



  1. Fraud Detection


Here comes another important application of deep learning that is, Fraud detection. It is very useful for the banking and financial sector as nowadays people are dependent on digital transactions.


Autoencoders in Keras and Tensorflow are being created to detect credit card frauds saving billions of dollars of cost in recuperation and protection for monetary organizations.


Due to this advanced technology people easily trust banks and online transactions, and believe in digital security.


Fraud prevention and detection are done dependent on recognizing designs in client transactions and credit scores, distinguishing bizarre conduct and anomalies.


Therefore, classification and various regression techniques under machine learning methods and neural networks are used for fraud detection.
