What is Deep Learning?

Wonder how Amazon sponsored ad & Netflix recommendations are tailor-made to our preferences? The answer, Artificial Intelligence algorithms. Machines are smart but can’t learn independently. Human programming intervention becomes necessary to keep algorithms in place, and this evolves with advancements in new technologies. Deep learning continuously teaches computers to do what comes naturally to humans. Due to its unique and straightforward image structure, it’s a well-known neural network dialect utilized today. With its help, machines started performing the job automatically and achieved state-of-the-art accuracy, exceeding human-level performance.

Difference Between Machine Learning and Deep Learning?

Let’s understand the fundamental distinction between these two:

Machine Learning Deep Learning
Data Volume Thousands of data points. Millions of data points.
Output Numerical value, like classification or score. Anything from numerical value to free-form elements, like free text or sound.
How it works Uses various automated algorithms that learn to model functions and predict future actions from data. Uses neural networks that pass data through processing layers to interpret data features and languages.
How it’s managed Data Analysts direct algorithms specific variables in data sets. Algorithms are self-directed on data analysis once they’re put into production.

How Does Deep Learning Work?

Deep Learning works much like the human brain. Like neurons in our brains receive thousands of signals from other neurons, deep learning neural network signals travel between nodes. Eventually, a heavier weighted node affects the next layer of nodes. Finally, the last layer compiles the weighted inputs and produces an output. A deep learning system requires advanced hardware because of millions of data points and as it involves several mathematical calculations. However, still, deep learning training computations can take weeks. Over time, the program trains itself, and the probability of correct answers increases. The best example of this is the facial recognition program, which accurately identifies faces with time.

Why Deep Learning Matters?

Deep learning was first theorized in the 1980s, but it has become significant. This is its high recognition accuracy, which helps meet user expectations and is crucial for safety applications like driverless cars. Continuous learning and advancement in deep learning have improved it to the point where deep learning outperforms humans in many tasks.

Examples of Deep Learning at Work

Deep learning applications are used right from automated driving to healthcare facilities.

Aerospace and Defense:

Objects are being identified from satellites that locate areas of interest, safe or unsafe zones for soldiers.

Medical Research:

Deep learning is used to detect cancer cells. Recently, at UCLA, teams built an advanced microscope that capitulates a high-dimensional data set to train a deep learning application to identify cancer cells automatically.

Industrial Automation:

Deep Learning has enabled modern machinery to detect & stop when people are within an unsafe distance of machines. This has ensured worker’s safety.


Deep learning also plays an essential role in automated hearing and speech translation. For example, Voice recognition devices know your choices. Deep learning applications also power this.
