What Is Deep Learning?

Deep learning is a type of machine learning (which is a subset of AI) that consists of layers of neural networks that process data and learn to define and classify certain objects within that data. Each layer of neural networks uses the insights of the previous one to improve the accuracy with which they classify objects and make predictions.

Deep learning can handle larger sets of complex data, process unstructured data and recognize new features within data on its own, displaying a great degree of automation.    


Why Use Deep Learning?

Automated Workflows

Deep learning’s ability to recognize new features within data sets means human workers can spend less time having to train deep learning neural networks. These networks can then learn how to perform new tasks on their own, speeding up workflows through automation.  


Ideal for Complex and Unstructured Data 

If a company’s data is complex or raw, teams can rely on deep learning to process the data and provide timely insights. This advantage has become crucial as organizations are faced with the task of organizing massive amounts of big data.  


Ability to Scale With Growing Data 

Gathering more data can put a strain on traditional machine learning algorithms, but deep learning can keep up with larger quantities of data. This trait makes deep learning neural networks ideal for companies operating in cloud and edge environments. 


Unwavering Accuracy

Deep learning is able to learn tasks quickly with its layers of neural networks, and these networks also work to enhance their abilities and predictions. That means deep learning can tirelessly perform tasks with a degree of accuracy that human workers are unable to replicate.  


Cost-Efficient Solutions

Deep learning can save teams time and resources by automating tasks, making use of unstructured data and adapting to increasing amounts of data. It can also single out flaws in products or errors in code. This way, businesses can reduce the costs of product-related accidents and having to recall faulty devices.  


Future of Deep Learning Applications 

As the world becomes more interconnected, automated and data-saturated, society as a whole may come to rely more heavily on deep learning for everyday functions, whether that’s spotting credit card fraud or powering autonomous vehicles. And deep learning’s ability to process complex and large data sets makes it the perfect solution for companies that may have outdated data platforms and systems. 

To get a sense of how deep learning is being applied today, take a look at 20 innovative deep learning examples below. 


Top Deep Learning Applications to Know

Fraud Detection

Fraud is a growing problem in the digital world. In 2022, consumers reported 2.4 million cases of fraud to the Federal Trade Commission. Identify theft and imposter scams were the two most common fraud categories.

To help prevent fraud, companies like Signifyd use deep learning to detect anomalies in user transactions. Those companies deploy deep learning to collect data from a variety of sources, including the device location, length of stride and credit card purchasing patterns to create a unique user profile.

Customer Relationship Management

Customer relationship management systems are often referred to as the “single source of truth” for revenue teams. They contain emails, phone call records and notes about all of the company’s current and former customers as well as its prospects. Aggregating that information has helped revenue teams provide a better customer experience, but the introduction of deep learning in CRM systems has unlocked another layer of customer insights.

Deep learning is able to sift through all of the scraps of data a company collects about its prospects to reveal trends about why customers buy, when they buy and what keeps them around. This includes predictive lead scoring, which helps companies identify customers they have the best chances to close; scraping data from customer notes to make it easier to identify trends; and predictions about customer support needs.
