Artificial intelligence, commonly referred to as AI, is a technological marvel that allows computers and machines to mimic human intelligence and problem-solving capabilities. This technology can perform tasks that would ordinarily need human intelligence or intervention. For instance, digital assistants, GPS guidance, autonomous vehicles, and generative AI tools such as Open AI's Chat GPT are all examples of AI applications in our daily lives.
Artificial Intelligence: Learning from Data
Artificial intelligence, as a field of computer science, encompasses machine learning and deep learning. These disciplines involve the development of AI algorithms, which are modeled after the decision-making processes of the human brain. These algorithms can 'learn' from available data and make increasingly more accurate classifications or predictions over time.
For example, a common application of AI algorithms is in autonomous vehicle technology used in the United States and globally. These vehicles use AI to learn from vast amounts of data about the environment, traffic rules, and human driving behavior.
AI technology has evolved to the point where it now can learn and synthesize not just human language, but other data types including images, video, software code, and even molecular structures. This evolution marks an exciting turn in the field of AI, particularly in natural language processing (NLP).
However, as AI tools become more integrated into business and daily life, discussions about AI ethics and responsible AI usage become vital. It's crucial to ensure that AI systems respect privacy, work transparently, and promote fairness.
Categories of Artificial Intelligence
Artificial intelligence can be broadly divided into two categories: weak AI and strong AI.
Weak AI, also known as narrow AI or artificial narrow intelligence (ANI), is AI trained to perform specific tasks. Weak AI drives most of the AI that surrounds us today. Despite its name, weak AI enables some very robust applications, such as Amazon's Alexa and self-driving vehicles.
On the other hand, strong AI comprises artificial general intelligence (AGI) and artificial super intelligence (ASI). AGI is a theoretical form of AI where a machine would have an intelligence equal to humans. This machine would be self-aware and capable of problem-solving, learning, and planning for the future. ASI would surpass the intelligence and ability of the human brain. While strong AI is still entirely theoretical, it doesn't stop AI researchers from exploring its development.
Machine Learning and Deep Learning
Machine learning and deep learning are sub-disciplines of AI, with deep learning being a sub-discipline of machine learning. Both these sub-disciplines use neural networks to 'learn' from vast amounts of data. These networks, modeled after the human brain, consist of interconnected nodes that extract features from data and make predictions.
Machine learning algorithms typically use neural networks with an input layer, one or two 'hidden' layers, and an output layer. This method requires the data to be structured or labeled by human experts.
In contrast, deep learning algorithms use deep neural networks, which consist of an input layer, three or more hidden layers, and an output layer. These multiple layers enable unsupervised learning, automating the extraction of features from large, unlabeled datasets. As such, deep learning essentially enables machine learning at scale, reducing the need for human intervention.
Generative AI and Its Future
Generative AI refers to deep-learning models that can generate statistically probable outputs when prompted. These models have been used in statistics for years to analyze numerical data. However, the rise of deep learning made it possible to extend them to images, speech, and other complex data types.
A recent AI model by Open AI, GPT-3, exemplifies the potential of generative AI. It has shown that in the future, AI models will be trained on extensive unlabeled data, which can be used for different tasks with minimal fine-tuning. Such foundation models will dramatically accelerate AI adoption in enterprises, making it easier for businesses to deploy AI in a wider array of mission-critical situations.

Applications of AI
AI systems have several real-world applications today. For instance, speech recognition, also known as automatic speech recognition (ASR), uses natural language processing to process human speech into a written format. Many mobile devices incorporate speech recognition to conduct voice searches or provide more accessible texting options.
Another application of AI is in customer service, where online virtual agents and chatbots are replacing human agents. These AI systems answer frequently asked questions, providing guidance and support to customers around the clock.
Artificial intelligence is a rapidly evolving field with vast potential. With advancements in machine learning, deep learning, and generative AI, we can expect to see increasingly sophisticated AI applications in various domains, from autonomous vehicles to customer service. As AI continues to learn and grow, it's clear that its intelligence is becoming an integral part of our future.
