Neural Networks And Their Potential For The Future

Artificial neural networks are self-learning algorithms where you don’t have to define rules and conditions. The algorithm itself learns how to handle the input data through trial and error.

Neural Networks And What They Have In Common With The Human Brain

The human brain is the most complex organ nature has ever produced. The brain’s neurons use chemical and electrical processes to receive input signals, convert them, and create output.

Artificial neural networks work like the human brain.

With the help of specially developed algorithms and deep learning methods, neural network applications can learn independently and recognize complex patterns in incredible amounts of data.

However, artificial neural networks do not even begin to reach the complexity of our brain, which consists of around 100 billion neurons. By comparison, computer systems can use their computing power to simulate neural networks of about 100,000 neurons. 

Structure Of Neural Networks

Artificial neural networks have a so-called input layer of neurons where each connection has a certain weight. The last layer provides the output that classifies different patterns and returns specific results.

Neural networks must train to solve problems, and the availability of qualified data plays a decisive role here. As a rule of thumb, the more data, the better. Neural networks often deliver even worse results than classical machine learning methods without valid data.

The artificial neural network learns to adjust the connections and connection strength between different neurons. Then the network extracts and classifies certain patterns.

A simple example would be that photos of any pet can be input, analyzed across the layers, and finally classified in the output layer as to whether the photo shows a dog.

How Do Artificial Neural Networks Learn?

Neural networks learn from experience, that is, through training methods that draw on large amounts of data and analyze it over and over again. The knowledge gained in each analysis step can be correlated and linked to further data.

Finally, the neural network can make decisions based on the links. By continuously questioning the findings, the connections between the neurons get certain weights—if the system confirms the information, their weight increases; otherwise, their weight decreases.

Ideally, this process continues until all patterns are correctly recognized. It is an iterative process in which a deep learning algorithm adjusts the weights until the output matches the desired result.

Where Are Neural Networks Used?

Neural networks show their strength, especially in deep learning methods. The specialists use these methods when other machine learning methods have reached their limits.

Neural networks are typically used in facial, object, or speech recognition. You’ve already used the benefits of neural networks in voice assistants such as Siri, Alexa, Google Assistant, or Facebook’s automatic facial recognition software.

In facial recognition, the system breaks input images down into smaller components. As a result, deep learning applications learn to identify faces. Then it is possible to train them specifically for visual face recognition and integrate them into complicated software solutions.

Machine learning has also become popular in entertainment and gambling. For example, in 2017, artificial intelligence won in a No-limits Texas Hold’em poker tournament. Who knows, maybe it will be even possible to fight artificial intelligence in online casinos like CasinoChan?

In addition, automatic image recognition has an essential role in critical applications like medicine, where doctors use artificial intelligence to diagnose diseases. Then AI learns to spot abnormalities such as cancer tumors in X-ray images.

Get Started With Neural Networks

You don’t need to be a research scientist or have a large budget to work with deep learning technologies. You can access many free tools to help you learn and develop neural networks today.

Easy access to building neural networks creates opportunities to rapidly advance the technology and threats from new entrants that displace reputable names and spur innovation.

Problems With Neural Networks

Neural networks learn from input data. That’s why the quality, selection, and balance of that data are critical factors. Self-learning algorithms can’t produce good output data with poor-quality inputs and missing values.

Another problem with artificial neural networks is the traceability of results. The networks are black-box models. Therefore, it’s very complicated to understand the decisions of a neural network depending on the number of hidden layers.

And, despite all the enthusiasm, we should not forget that today’s artificial neural networks cannot even begin to represent the complexity and universal applicability of the human brain. Who knows, maybe they will overcome the human brain one day?
