Introduction
In today's digital age, technology is omnipresent, and society is steadily moving towards greater automation and digitization. This trend has been further accelerated by the COVID-19 pandemic, with remote work and store closures making modern society even more reliant on digital technology. Behind all this, artificial intelligence (AI) plays a crucial role. This article delves into artificial intelligence models and how they are transforming our lives and work.
What Are Artificial Intelligence Models?
Artificial intelligence models are tools and algorithms designed to train computers to process and analyze data in a manner similar to human cognition. These models enable machines to learn from data, recognize patterns, and make decisions with minimal human intervention. They are the core technologies that drive automation and intelligence.
The Basic Idea
Technology is everywhere these days. Society has steadily moved towards increased automation and digitization, a trend that has been exacerbated by the COVID-19 pandemic. Work-from-home orders and storefront closures have solidified modern society as a digital era. Increased automation and digitization have been made possible thanks to artificial intelligence. AI is all about making computers and machines make decisions like humans. By programming computers to mimic human thinking patterns, they can perform aspects of our jobs. While the idea of robots taking over the world might seem scary (cue the sci-fi movies), AI can make processes much more efficient and often more accurate.
Types of Artificial Intelligence Models
Artificial intelligence models are the tools and algorithms used to train computers to process and analyze data, much like humans do. Here are some key types:
- Machine Learning: A broad category of AI models where computers are taught to think independently and develop their own algorithms after processing vast amounts of data.
- Supervised Learning Models: These models require human training. People tag sets of data, and the model learns from how humans analyze the data.
- Unsupervised Learning Models: These models require no human input. They are trained by software that identifies patterns, allowing the computer to mimic them.
- Semi-Supervised Learning Models: These models combine both supervised and unsupervised approaches, using both human training and software training.
- Deep Learning: A technique where the machine develops an algorithm after encountering vast amounts of data, without the need for an initial algorithm to be inputted.
Practical Examples
For instance, Google Maps and other navigation applications use artificial intelligence models to guide us to our destinations. The machine remembers the edges of buildings it learned from data from other travelers and through inputted data via an algorithm. As people use the application daily, the model incorporates the data gathered from these travels and can provide more accurate route information by recognizing changes in traffic flow.
The Debate: Enhancement or Redundancy?
A big question remains: do artificial intelligence models enhance humanity and society, or do they run the risk of making humans redundant? Here are two different perspectives:
- Stephen Hawking: "The development of full artificial intelligence could spell the end of the human race... It would take off on its own, and re-design itself at an ever-increasing rate. Humans, who are limited by slow biological evolution, couldn’t compete, and would be superseded."
- Ginni Rometty: "Some people call this artificial intelligence, but the reality is that this technology will enhance us. So instead of artificial intelligence, I think we’ll augment our intelligence."
Key Terms
- Artificial Intelligence: A branch of computer science where machines mimic human problem-solving and decision-making. It is the opposite of "natural intelligence," exhibited by humans and animals.
- The Artificial Intelligence Effect: A phenomenon where people no longer see AI for what it is after it becomes a widespread part of daily life. It is seen as a tool because we are so used to technology completing tasks and hiding the work behind it.
- Machine Learning: The process of a computer attempting to learn from the past. Data is inputted into a machine, passed through an algorithm, and churns out an output. If the computer returns the correct result, it affirms the algorithm. If it is wrong, it adjusts its algorithm accordingly.
- Neural Networks: Artificial models designed to mimic how neurons in our brain interact. An input triggers a response and creates an output.
- Deep Learning: A technique where the machine develops an algorithm after encountering vast amounts of data.
- Turing Machine: A hypothetical machine developed by mathematician Alan Turing in 1936. It could simulate any computer algorithm by changing data into 0s and 1s.
- Supervised Machine Learning Models: Models that require human training.
- Unsupervised Machine Learning Models: Models that require no human input.
- Semi-Supervised Machine Learning Models: Models that combine both supervised and unsupervised approaches.
History
The concept of artificial intelligence has a rich history. Mathematicians Alonzo Church and Alan Turing were the first to use computation as a device for formal reasoning. They developed the Church-Turing thesis in 1936, suggesting that any real-world computation could be translated into an equivalent computation involving a Turing machine. This opened up the realm of possibilities for computer learning.
In 1943, neuroscientist Warren Sturgis McCulloch and logician Walter Harry Pitts formalized the first computation theory of mind and brain, explaining how neural mechanisms in computers could realize mental functions.
Artificial intelligence became a reality in 1949 when computers could store commands. The term "artificial intelligence" was coined in 1955, and computer scientists Allen Newell, Cliff Shaw, and Herbert Simon created the Logic Theorist, a program that used AI to mimic human problem-solving skills.
In 1997, American computer scientist Tom Mitchell provided a more refined definition of AI: "A computer program is said to learn from experience E with respect to some task T and some performance measure P, if its performance on T, as measured by P, improves with experience E."
Consequences
Artificial intelligence models have numerous practical and important uses. They help make data analysis and processing more efficient, increase automation, and revolutionize society. Initially, AI models were reactive machines that couldn't store memory, meaning they couldn't learn from experience. Today, all AI computers can store memory, making machines constantly better at analyzing data.
While deep learning machines learn entirely from experience, AI models continue to refine their algorithms through experience. These machines make processes more efficient, reduce the need for human intervention (and thus reduce human error), and help organizations understand how to improve their functions.
There are advantages to both machine learning models and AI models that do not learn solely from experience but use pre-programmed algorithms. Pre-programmed models can quickly process data and deliver desired results without the need for additional time to "learn," requiring simpler and cheaper machinery. Machine learning, although more expensive, can process more complex data and is self-sufficient, requiring less human input.
