Artificial Intelligence (AI)

What is Artificial Intelligence?

Artificial Intelligence (AI) is composed of two words Artificial (A) and Intelligence (I), where Artificial defines made by human and Intelligence defines the ability to understand, learn and thinking , hence AI means "a human-made understand, learn and thinking power."

 

Further, Intelligence, as defined “the ability to use memory, knowledge, experience, understanding, reasoning, imagination and judgment to solve problems and adapt to new situations”. The ability described above when exhibited by machines is called as Artificial intelligence (AI). It is intelligence exhibited by machines.

 

Artificial Intelligence (AI), also known as machine intelligence, is a field of computer science that focuses on creating systems and machines capable of performing tasks that typically require human intelligence. These tasks include problem-solving, learning from experience, understanding natural language, recognizing patterns, and making decisions.

 

Artificial Intelligence (AI) is not a single technology. It is an umbrella term that includes any type of software or hardware component that supports machine learning (ML), deep learning (DL), computer vision (CV), reinforcement learning (RL) and natural language processing (NLP).

 

The some of the examples of Artificial Intelligence (AI):

• Advanced Web Search Engines: (e.g., Google), 
• Recommendation Systems: (e.g., YouTube, Amazon and Netflix),

How Artificial Intelligence (AI) Works?

Artificial intelligence (AI) works by combining large amounts of data with fast, iterative processing and intelligent algorithms, allowing the software to learn automatically from patterns or features in the data. Artificial Intelligence can be used to solve real-world problems by implementing the following processes/ techniques:

1. Machine Learning

• Machine Learning is a sub-set of Artificial Intelligence (AI).  Machine Learning ability to learn from experience and to interpret, process and analyse data in order to solve real-world problems.
• Machine Learning algorithms automatically learn and improve by learning from large datasets of data, and they can then use this data to make predictions or decisions. They do not need explicit instructions to produce the desired output

 

2. Deep Learning

• Deep Learning is a sub-field of machine learning. This is concerned with algorithms inspired by the structure and function of the brain called artificial neural networks.
• Deep Learning is the logic behind the face verification algorithm on Facebook, self-driving cars, virtual assistants like Siri, Alexa and so on.

 

3. Neural Networks

• Neural Network is a series of algorithms that captures of the relationship between various underlying variables and processes the data as a human brain.
• Neural networks are inspired by the structure of the human brain, and they can be used to solve a wide range of problems, including image recognition and natural language processing.

 

4. Natural Language Processing

• Natural language processing is the ability of machines to understand and process human language. This is used in a variety of applications, such as machine translation, speech recognition, and text summarization.
• Twitter uses Natural language processing to filter out terroristic language in their tweets, Amazon uses Natural language processing to understand customer reviews and improve user experience.

 

5. Computer Vision

• Computer Vision is a field of study where techniques are developed enabling computers to see and understand the digital images and videos. The goal of computer vision is to draw inferences from visual sources and apply it towards solving a real-world problem.

What are the Learning Stages of Artificial Intelligence?

There are many different ways to classify the learning stages of artificial intelligence (AI). The key learning stages of artificial intelligence (AI) include:

1. Data Collection and Preprocessing: 

• In the initial stage, artificial intelligence (AI) systems gather relevant data from various sources. Data can be structured (e.g., databases) or unstructured (e.g., text, images, videos). Data preprocessing involves cleaning, formatting, and organizing the data to make it suitable for analysis and learning. This may include removing noise, handling missing values, and normalizing data.

 
2. Supervised Learning: 

• This is the most common type of machine learning. In supervised learning, the artificial intelligence (AI) is given a set of labeled data, and it learns to associate labels with inputs. For example, an artificial intelligence (AI) trained on a set of labeled images of dogs and cats would learn to identify dogs and cats.

 
3. Unsupervised Learning: 

• In unsupervised learning, the artificial intelligence (AI) is not given any labeled data. Instead, it learns to find patterns in the data on its own. For example, an artificial intelligence (AI) trained on a set of unlabeled images might learn to cluster the images into different groups based on their similarities.

 
4. Reinforcement Learning: 

• In reinforcement learning, the artificial intelligence (AI) learns by trial and error. It is given a reward for taking actions that lead to desired outcomes, and it is penalized for taking actions that lead to undesired outcomes. For example, an artificial intelligence (AI) trained to play a game of chess would learn to take actions that lead to checkmate and avoid actions that lead to being checkmated.

 
5. Meta Learning: 

• In meta learning, the artificial intelligence (AI) learns how to learn. This allows it to adapt to new tasks and environments more quickly. For example, an AI trained on a set of different games would learn to learn the rules of new games more quickly.

 

These learning stages collectively represent the journey of artificial intelligence (AI) development from data acquisition to becoming a capable, adaptable, and interpretable system. AI systems continue to learn and evolve throughout their operational lifecycles to stay relevant and effective.
