What Is Deep Learning- Everything You Need To Know [Explained]

March 26th, 2024
What Is Deep Learning

Computing is rapidly revolutionizing and at the center of this revolution lies artificial intelligence and machine learning. Both these technologies, and the ones branching out from these, are hinged on their feature to recognize patterns in data. Think about the streaming suggestions by Netflix or the shopping cues by Amazon. Most machines using AI principles are smart, but do not have the prowess to learn on their own. Hence, making human intervention necessary. Deep learning, on the contrary, is fully capable on its own. But what is deep learning and why is it such a hyped technology?

Let's decode everything about it!

What Is Deep Learning?

So, what is deep learning? Deep learning (DL) is a division of machine learning and falls within the category of artificial intelligence. The DL technology works by teaching a computer model to follow the principle of learning by example. It is similar to how a child learns from the behavior and actions of teachers and parents.

It supports and works with all kinds of data such as images, text, audio, etc. Hence, the computer is tuned to read and process data much like a human brain. This is done by using neural networks (NN).

What are Neural Networks?

What are Neural Networks?

Neural networks (NNs) refer to computational models that work in the same way as a human brain functions. These comprise of interconnected neurons or nodes that know how to process and learn from data. Hence, paving the path for tasks like decision making and pattern recognition.

These have an imperative task to play with their sea of abilities. These include identifying patterns, adjusting to the surrounding changes, and solving intricate puzzles. This capacity to learn from data is revolutionary and has led to the evolution of various technologies.

What Is Machine Learning vs Deep Learning?

Machine Learning vs Deep Learning

Now that you know ‘what is deep learning', you know that it is a subset of machine learning. However, do you know what is machine learning vs deep learning? What exactly makes these two different from one another? Let's find out!

DL is a subset of machine learning.ML is a subset of artificial intelligence.
It requires humongous amounts of data to train on.It can train on considerably smaller data sets too.
This model learns from its own past mistakes and environment.It needs human intervention to correct its mistakes.
It has a longer training period but delivers higher accuracy.It has a shorter training period and delivers lower accuracy.
DL requires a specialized GPU to train.ML can be trained on a CPU.

Examples of Deep Learning

Deep Learning Examples

DL has branched out significantly and today, it is being used in different industries for different tasks. Some of the most commonly found examples of DL are listed here.

  1. Self-Driving Cars

Autonomous cars are already swifting down the road and that has been possible due to deep learning with TensorFlow. A driverless car is no longer a work of fiction because of the millions of scenarios it has been exposed to.

  1. Facial Recognition

The most common example is the iPhone's facial recognition system that uses DL to identify your facial data points and unlocks the phone. It is not negatively affected by factors like gaining, loss, growth, or chopping of hair, weight, or beard.

  1. Personalization

Ever wondered how Netflix knows you like sci-fi or how Amazon knows you might be interested in red t-shirts? It is all thanks to the DL capabilities that they are investing in more and more. In fact, various organizations are expected to work around DL in the coming years.

  1. Virtual Assistants

Siri, Google Assistant, Alexa, and Amazon Echo are all great examples of virtual assistants. These learn to recognize voices and accents to offer a secondary human experience.

  1. Medical Science

Fitness bands, virtual assistants, and gears are only a few examples of computers recording data to learn about our mental and physiological conditions. This leads to detection and personalized healthcare.
