What is Neural Network in Machine Learning With Example

What is Artificial Neural Networks

Artificial neural networks (ANNs) are computing systems inspired by biological neural networks, like those in humans and animals. While they mimic biological systems, ANNs are not as complex, making exact replication in technology challenging.

The primary function of ANNs is to “learn” tasks by analyzing examples rather than being explicitly programmed with specific rules. By processing examples, ANNs develop the ability to perform tasks independently.

ANNs gained popularity in the mid-1900s, with computer scientists continually refining them. Over time, ANNs have evolved into powerful tools, enabling computers to achieve human-like capabilities, such as handwriting recognition and language learning.

Artificial neural networks are likely to be the basis for any form of artificial intelligence that represents the form of robots that people frequently think about when they consider a robotic “species.” For example, a robot that had human-like qualities both in appearance and in functionality. If a robot ever were to be developed in this capacity, it is likely that it would be programmed with the support of artificial neural networks. 

What Are Artificial Neural Networks? 

Artificial neural networks (ANNs) are computerized models inspired by biological neural networks, but they differ in complexity and function. ANNs learn by processing examples rather than having prior knowledge. For instance, an ANN can be trained to recognize images of cats by analyzing labeled examples. Over time, it learns to identify cats without understanding their physical traits, making it a powerful algorithm.

The purpose of ANNs is to solve problems like the human brain, but they have evolved to perform specialized tasks such as computer vision, speech recognition, social media filtering, gaming, medical diagnosis, and even painting, with remarkable accuracy.

How Does They Work? 

Artificial neural networks (ANNs) consist of interconnected units called artificial neurons, inspired by biological neurons but different in behavior. These neurons transmit information to each other, creating patterns and “understanding” through complex algorithms, though they lack human emotions or sentience.

Artificial neurons are coded with real numbers and connect via edges, with weights determining their capacity. During learning, these weights adjust, and neurons collaborate if thresholds are reached. ANNs can be static (limited units and layers) or dynamic (evolving structures), with dynamic ones being more complex but quicker at learning.

ANNs vary in supervision levels. Some require significant human oversight to ensure proper learning, while others operate independently, capable of performing a wide range of tasks with minimal intervention.

When Should They Be Used?

Artificial neural networks (ANNs) often spark ethical debates, particularly among those concerned about potential dangers. While such fears are valid, today’s ANNs are far from autonomous threats, lacking the physical capabilities to act independently. Although powerful, they don’t yet combine advanced intelligence with functional robotics.

Despite these concerns, ANNs are widely used in various fields. They have become central to tasks like identification, process control, game playing, recognition, 3D reconstruction, diagnosis, financial analysis, and data filtering. This technology has advanced significantly, with diverse applications already in place.

Identification and Process Control

Artificial neural networks (ANNs) excel in identification and process control, enabling systems to recognize and manage specific functions. A notable example is self-driving vehicles, where ANNs allow cars to monitor behaviors and assist drivers. For instance, modern vehicles can automatically apply brakes to avoid collisions with pedestrians or obstacles. While still under development and debate, these systems are increasingly being integrated into everyday vehicles.

General Game Playing

Artificial neural networks (ANNs) have been highly successful in both physical and virtual game playing. Machines have been trained to play games like chess or checkers, often outmatches human opponents. These systems can either request human assistance to move pieces or use robotic arms to make moves autonomously.

In digital gaming, ANNs can control game-playing devices, like on Xbox or PlayStation, by “watching” the screen and playing as a human would. These networks quickly learn new strategies, becoming increasingly formidable. Over time, they can reach a level of play that’s nearly unbeatable by the average human player.

Various Forms of Recognition

Artificial neural networks (ANNs) excel at recognizing faces, voices, gestures, handwriting, and even text, enabling them to “read” and act on information. They can also detect patterns in data, codes, or signals, allowing them to respond to specific sequences with predefined actions.

Recognition allows ANNs to classify and process information, guiding other system components to perform tasks. While ANNs handle the “thinking” and signaling, tasks like robotic movement are triggered by separate programming based on the network’s output.

3D Reconstruction

3D reconstruction allows computers to capture and manipulate the shape and appearance of real objects. This technique is often used to enhance designs or in medical imaging. Artificial neural networks (ANNs) significantly aid in 3D reconstruction, making them fundamental to the process.

Diagnosis

Artificial neural networks (ANNs) can assist in medical diagnosis, such as identifying various types of cancers like lung and prostate cancer, and distinguishing between cancerous and healthy cells. However, ethical standards require human validation of ANNs’ diagnoses through manual tests to ensure accuracy.

Finances

In finance, artificial neural networks (ANNs) are used for automated trading systems, allowing high-tech traders to make consistent trades and earn passive income without active involvement. Additionally, ANNs were used in the early days of cryptocurrency to mine coins, participating in pioneering cryptocurrency experiments and generating substantial profits.

Filtering

Artificial neural networks (ANNs) are widely used for spam and content filtering in social networks and emails. For emails, ANNs classify messages as spam or not, with humans able to override these classifications if necessary.

In social networks, ANNs perform more complex tasks, such as detecting and removing inappropriate content (nudity, violence), applying filters to graphic images, and identifying potentially dangerous posts to offer support. They also handle spam filtering and bot removal, enhancing the platform’s integrity.

ANNs represent advanced technology with potential future applications in developing sophisticated robots. Although ethical concerns and other issues need addressing, the prospect of more advanced robotic systems could revolutionize our society.
