What is deep learning?

Deep learning is a subset of machine learning which is basically a neural network with three or more layers. This neural network attempts to simulate the behavior of the human brain, although it is far from “learning” from large amounts of data. While single-layer neural networks can still make rough predictions, additional hidden layers can help optimize and improve accuracy.

Deep learning enables many artificial intelligence (AI) applications and services that can enhance automation to perform analytical and physical tasks without human intervention. Deep learning technologies support everyday products and services (such as digital assistants, voice-activated TV remote controls, and credit card fraud detection) and new technologies (such as self-driving cars).

In-depth training and machine learning

If deep learning is a subset of machine learning, what difference does it make? The difference between deep learning and classic machine learning lies in the type of data and the learning methods used.

Machine learning algorithms use structured and labeled data to make predictions, which means that certain features are determined from model input and arranged in tables. This doesn’t mean that you don’t use unstructured data; it just means that if you do, you will usually process it first to organize it in a structured format.

Deep learning eliminates data preprocessing typically associated with machine learning. This algorithm can capture and process unstructured data such as text and images, and extract functions automatically, eliminating dependence on human experts. For example, let’s say we have a number of photos of different pets and we want to categorize them by cats, dogs, hamsters, and so on. Deep learning algorithms can determine which functions (eg ears) are most important in distinguishing one animal from another. In machine learning, these role hierarchies are set manually by human experts.

Then, through the process of backward propagation and gradient descent, the deep learning algorithm adapts to its own accuracy and adjustment so that it can predict new animal images more accurately.

Machine learning and deep learning models can also carry out various types of learning, usually divided into supervised learning, unsupervised learning, and reinforcement learning. Supervised training uses tagged records for classification or prediction; this requires human intervention to mark the input data correctly. In contrast to this, uncontrolled learning does not require identifying data records, but recognizing patterns in the data and grouping them according to different characteristics. Reinforced learning is the process by which the learning model performs more accurately in a feedback-based environment to maximize rewards.

This is how deep learning works

Deep learning neural networks, or artificial neural networks, attempt to mimic the human brain through a combination of data entry, weights, and deviations. These elements work together to accurately identify, classify, and describe objects in the data.

A deep neural network consists of several layers of interconnected nodes, with each layer built on top of the previous layer to improve and optimize predictions or classifications. The process of computing through this network is called forward propagation. The input and output layers of the inner neural network are called the visible layers. Deep learning models receive data for processing at the input layer and the final prediction or classification occurs at the output layer.

The simplest types of deep neural networks are described above in the simplest terms. However, deep learning algorithms are very complex and there are different types of neural networks to solve a particular problem or data set. For example.

Convolutional Neural Networks (CNNs) are primarily used in image classification and computer vision applications to identify features and patterns in images to perform tasks such as target detection or identification. In 2015, CNN first defeated a human in the Object Recognition Challenge.
