What is Deep Learning?

Deep learning is a subset of machine learning. It is a field that is based on self-learning and improvement through the examination of computer algorithms. Deep learning works with neural networks, which is design to mimic how humans think and learn. Until recently, neural networks were limited in complexity due to computing power constraints. However, advances in Big Data analytics have enabled larger, more sophisticated neural networks, enabling computers to observe, learn, and respond to difficult issues faster than humans. Image classification, language translation, and speech recognition have all benefited from deep learning. It can solve any pattern matching problem without the need for human intervention.

Deep learning is power by multi-layer artificial neural networks. Deep Neural Networks (DNNs) are such networks, with each element capable of order to accomplish tasks like depiction and abstract thought to make sense of pictures, sound, and text. Deep learning, consider the fastest-growing field in machine learning, is a truly disruptive digital technology that is use by an increasing number of companies to create new business models.

Now that you know what Deep Learning is, let’s look at how it works.

How Does Deep Learning Work?

Neural networks consist of layers of nodes, similar to how the human brain is made up of neurons. Individual layer nodes are link to nodes in adjacent layers. The number of layers in the network indicates how deep it is. In the human brain, a single neuron receives thousands of signals from those other neurons. Signals travel between nodes in an artificial neural network and is assign weights. A node with a higher weight will have a greater influence on the nodes below it.

The final layer assembles the weighted inputs to generate an output. Deep learning systems require powerful machines to collect and process data and perform several complex mathematical problems. Deep learning training calculations, even with such advanced hardware, can take weeks.

Deep learning systems necessitate a huge amount of data in order to produce accurate results; thus, information is fed in the manner of massive data sets. When processing data, artificial neural networks can categorize it based on the answers to a series of binary true or false questions involving highly complex mathematical problems.

For instance, a facial recognition programme, learns to detect and recognise the edges and lines of faces, then more significant parts of faces, and eventually overall representations of faces. The programme trains itself over time, increasing the likelihood of correct answers. In this case, the facial recognition programme will identify faces more accurately over time.

Example of Deep Learning at Work

Assume the goal is for a neural network to recognise photos that contain a dog. Consider the differences in appearance between a Rottweiler and a Poodle. Furthermore, photographs depict dogs from various angles and with varying amounts of light and shadow. As a result, a training collection of photos must be compiled, which contains many explanations of dog faces that any human would label as “dog,” as well as pictures of non-dog objects labelled (as one might expect) “not dog.” Images are converted into data after being fed into the neural network. These data are transmitted through the network, and different nodes assign weights to different elements.

The final output layer combines the seemingly disparate information – furry, has a snout, has four legs etc. – and produces the output: dog.

The neural network’s response will now compare to the human-generated label. If a match is found, the output is confirm. If not, the neural network notifies the user of the error and adjusts the weightings. By repeatedly modifying its weights, the neural network attempts to improve its dog-recognition abilities. This is known as supervise learning, and it occurs even when the neural networks are not explicitly told what “makes” a dog. They must learn on their own and recognise patterns in data over time.

Advantages of Deep Learning

Feature Generation Automation

Deep learning algorithms can produce new features from a small set of features in the training dataset without any need for additional human intervention. This means that deep learning can handle complex tasks that frequently necessitate extensive feature engineering. This means faster implementation or technology rollouts with higher accuracy for businesses.

 Works Well With Unstructured Data

Deep learning’s ability to work with unstructured information is one of its most appealing features. This is especially important in the business context, considering the majority of business data is unstructured. Text, images, and voice are just a few of the most common information formats use by businesses. Because traditional ML algorithms are confined in their ability to analyze unstructured data, this wealth of information frequently goes untapped. And this is where deep learning has the most potential.

Deep learning networks trained with unstructured information and appropriate labelling can assist businesses in optimising nearly every function, from marketing and sales to finance.

Better Self-Learning Capabilities

Deep neural networks’ multiple layers enable models to become more productive at learning advanced structures and performing more intensive computational tasks, i.e., performing many complex operations at the same time. It outperforms machine learning in unstructured dataset machine perception tasks (the ability to make sense of inputs like pictures, sounds, and video as a human would).

This is because deep learning algorithms can eventually learn from their own mistakes. It can check the accuracy of its predictions/outputs and make adjustments as needed. Classical machine learning models, on the other hand, necessitate different degrees of human intervention to determine output accuracy.

Cost Effectiveness

While training deep learning models can be costly, once trained, they can assist businesses in reducing unnecessary spending. The cost of an incorrect prediction or product defect is enormous in industries such as manufacturing, consulting, and even retail. It frequently outweighs the costs of developing deep learning models.

Deep learning algorithms can account for variation across learning features to drastically reduce error margins across industry sectors and verticals. This is especially true when comparing the limitations of traditional machine learning models to deep learning algorithms.


Deep learning is highly scalable because of its ability to process large amounts of data and perform numerous computations in a cost – effective and time manner. This has a direct impact on productivity (faster deployment/rollouts), as well as modularity and portability.

Google Cloud’s AI platform prediction, for example, enables you to run your deep neural network at scale on the cloud. So, in addition to better model organisation and versioning, you can scale batch prediction by leveraging Google’s network infrastructure. The number of nodes in use is then automatically scale base on request traffic, which improves efficiency.
