Ever wondered why your Google Assistant or Siri can't engage in deep conversations about life? That's because they fall under the category of Artificial Narrow Intelligence (ANI).
The term looks fancy, right? I'll explain it in simpler terms, but to go there, we have to start from the beginning.
What is Artificial Intelligence (AI)?
Artificial intelligence is a machine's ability to mimic how the human brain works and intelligence. In some places, it is called machine intelligence. We can divide this into three types of AI:
- Artificial narrow intelligence (ANI), which has a narrow range of abilities and designed to perform one thing;
- Artificial general intelligence (AGI), which is on par with human capabilities or
- Artificial superintelligence (ASI), which is more capable than a human.
Today, we are focusing on one type of AI: Narrow AI.
What is Deep Learning?
The easiest way to explain Deep Learning is that it is one of the more alluring branches of machine learning and explores artificial neural networks with stunning precision to simulate how human minds work.
At its heart, deep Learning relies on data collection as its driving force to enable computers to understand large volumes of information efficiently and quickly.
Deep Learning's hallmark lies in its mysterious depths, hidden layers that fine-tune precision while unlocking automation potential for today's AI innovations.
Consider that everyday items like digital assistants and autonomous vehicles rely heavily on deep Learning's prowess for success. What sets deep Learning apart from conventional machine learning, you ask?
Well, deep Learning excels at handling both structured and unstructured data sources efficiently, extracting features seamlessly without manual manipulation of information!
It takes the burden out of manual data handling by being an efficient data processing platform that handles everything automatically for us. Deep Learning can give your data analysis magic!
Deep Learning encompasses various learning styles: supervised, unsupervised, and reinforcement learning all offer unique capabilities for processing information.
Backpropagation and forward propagation processes combine in an intricate ballet, honing deeper learning into an intimidating but effective weapon.
Real-world applications of deep learning span across sectors like law enforcement, financial services, customer service, and healthcare, taking on roles like speech recognition systems or medical image analysis as examples of its magic in action.

What is Narrow AI / Weak AI?
Narrow AI, also known as Weak AI or Artificial Narrow Intelligence, is an Artificial Intelligence (AI) system designed to replicate and perhaps surpass human intelligence for a dedicated purpose to perform a specific task or a set of closely related tasks.
They're programmed to pull info from a specific dataset and stick to the task at hand, unlike the hypothetical Artificial General Intelligence (AGI), also known as Strong AI, which mimics human smarts across the board. It's basically a theoretical AI system that could be applied to any task or problem.
What can Narrow AI do?
The powers of narrow artificial intelligence are pretty remarkable within their specific territory. These systems are great at accurately analyzing massive datasets, spotting patterns and trends, and making smart predictions or decisions based on the data.
They can also get better over time, thanks to techniques like machine learning and deep learning.
Yet, there's a catch. Narrow AI cant do abstract thinking, understanding context beyond its programmed scope, or flaunting emotional smarts. Their learning is confined to the rules set by their algorithms and the data they've been trained on.
What is a Neural Network?
When we discuss about deep learning, we have to mention neural networks. Basically, a neural network is a technique used in the field of advanced artificial intelligence that aims to replicate the way the human brain processes information, and it's an important part of deep learning; these networks are structured with interconnected nodes or neurons, much like the neurons in our brains.
They come in handy for tasks such as recognizing handwriting and identifying faces. On the other hand, artificial intelligence (AI) seeks to mimic human cognitive abilities.
These Neural Networks draw inspiration from biological neural networks, forming a bridge between the natural and artificial.
Learning within these networks involves adjusting the weights of connections, a process categorized into three main types: supervised learning, unsupervised learning, and reinforcement learning.
There are nine different types of neural networks, each with its unique characteristics. These include the Perceptron, Forward Neural Network, Multilayer Perceptron, Convolutional Neural Network, Radial Basis Functional Neural Network, Recurrent Neural Network, LSTM – Long Short-Term Memory, Sequence Sequence Models, and Modular Neural Network.
