We’ve been talking about how amazing deep learning is. But wait! What is this term?

Let’s jump into our first topic and understand deep learning definition.

What is Deep Learning?

Deep Learning is the subset of ML or Machine Learning. Machine Learning, whereas, is a subset of Artificial Intelligence.

The algorithms in DL are trained in a way that they are expected to produce outcomes similar to what a human brain would do.

In deep learning, features or factors on which the attributes are to be classified, are decided by the artificial neural networks, without any human interference.

So, let us first understand what is meant by the terms we used above:

Artificial Intelligence: A technique through which machines are trained to mimic human-like behavior.

Machine Learning: A technique in which data is used to run specific algorithms. These algorithms are used to train machines to achieve desired outcomes.

Deep Learning: It is a type of ML. DL uses an artificial neural network, which is inspired by the structure of the human brain.

Let us now dive into understanding the deep learning framework and how it works.

How does Deep Learning work?

Now it’s time to learn the workings of deep learning and here are the following points:-

Deep learning is like teaching a computer to learn and make decisions, just like humans. It involves using a special kind of software called a neural network. Think of it as a brain made of math.

Neural Networks: Deep learning uses something called neural networks, which are like a chain of simple math operations. These networks have layers, like the layers of an onion.
Learning from Data: We feed the neural network lots of data, like pictures of cats and dogs. The network learns by adjusting its math operations to get better at recognizing cats and dogs.
Layers of Learning: Each layer of the network looks for different features, like shapes, colors, and patterns. It’s like having detectives specialized in different clues.
Making Predictions: After learning from the data, the network can predict if a new picture is a cat or a dog. It’s like having a detective team that can tell you what’s in a mystery picture.
Feedback Loop: If the network makes a mistake, we tell it the correct answer, and it learns from that. It’s similar to teaching a friend by correcting them.
Deep Learning: Deep learning means having many layers of these networks, like layers of detectives working together to solve a complex case.

To design a well-trained and efficient network, the weights and biases in the neural network have to be continuously adjusted.

Deep Learning Applications

Almost all industries in the present day make use of deep learning in one or the other way. Deep Learning has a vast range of applications. Given below are some fascinating deep learning examples:-

Fraud Detection

Digitalization has many advantages, but with these advantages come the cons. One such disadvantage is Fraud. To overcome this issue of fraud, several organizations have started making use of deep learning concepts.

With the help of machine learning and neural networks, companies collect information, identify patterns in transactions, and discover unusual behaviors.

This way they can detect fraud and eventually take appropriate measures to prevent it.

Virtual Assistants

Almost everyone in the world today knows who google assistant, Siri, and Alexa are. They have slowly but surely gained their position and have become a part of numerous peoples’ daily lives. They can do everything from answering questions to playing songs and controlling smart home devices.

All these virtual assistants, although different, have the same basics. All of them are products of deep learning algorithms.

Self-driving cars

The primary factor behind autonomous driving is deep learning. DL algorithms are used to model the data, and as a result, judgments are made that are appropriate for the driving situation.

Neural networks help in identifying and navigating between different parts of the road and enable autonomous driving.

Self-driving cars today take into account your destination and map out the fastest, as well as, the most optimal routes.

One prominent application of deep learning in the healthcare sector is the detection and treatment of cancer.

Deep learning principles are applied to analyze MRI, X-Ray, and CT scan to provide detailed reports.

Customer Support

Numerous people contact and converse with customer support agents. Most of them do not even realize that they are talking to bots on the other end.

This is because with the help of deep learning the conversation seems too real to discern the difference.

Are you someone who usually gets machine and deep learning mixed up?

Don’t worry!

Keep reading to learn how to differentiate between the two.

Deep Learning vs Machine Learning

DEEP LEARNING	MACHINE LEARNING
It is the subset of Machine Learning. Deep learning can handle both structured and unstructured data.	It is the superset of Deep Learning and a subset of Artificial Intelligence. Machine learning mostly requires structured data.
It is used to solve complicated ML problems as it is trained to produce results mimicking the human brain.	It is used to solve simple or semi-complex problems.
Unlike machine learning, it uses an end-to-end approach to solve problems.	Machine learning breaks and solves each part to give the final result.
Deep learning is more effective as compared to Machine learning.	Although machine learning can easily be set up and run, it is comparatively less efficient than deep learning.
It requires a larger volume of data to train a machine.	It requires a relatively lesser amount of data to train the model.
Due to massive amounts of data, deep learning algorithms require more time to execute.	It takes less time than deep learning to execute. But it requires a long time to test the model.
When compared to machine learning, deep learning requires more stronger and powerful resources or hardware.	High-end machines are not required for machine learning. It works well even with standard and low-end machines.

With the rapidly increasing technologies and their applications, it is necessary to understand what the future looks like for them.

So, what does the future hold for deep learning?

Future Scope of Deep Learning

Deep learning has a lot of scope in the future in various industries.

It will help in transforming the current state of organizations by helping them make better decisions.
It will assist in improving the existing methods of data storage.

Conclusion

In conclusion, Deep Learning is a cutting-edge field that mimics how humans think using computer networks. It’s proven its worth in areas like spotting fraud, powering virtual assistants, and making self-driving cars possible. Unlike traditional Machine Learning, it’s better at handling complex tasks. Looking ahead, Deep Learning will keep growing, making machines smarter and helping organizations make better choices while storing data more efficiently. Choosing Deep Learning means embracing a future guided by smart technology and data-driven insights.
