Understanding AI Fundamentals

Before embarking on a journey through the world of artificial intelligence, one must familiarize oneself with the foundational elements. This includes understanding its history, distinguishing between key terms, grasping core concepts, and recognizing the different types of AI in existence.

History of Artificial Intelligence

Artificial Intelligence (AI) has its roots dating back to antiquity, but the formal foundation was laid in the mid-20th century. It was in 1950 when Alan Turing proposed the Turing Test as a measure of machine intelligence. Since then, AI has evolved from simple problem-solving programs to complex algorithms capable of learning and adapting.

AI versus Machine Learning versus Deep Learning

Artificial Intelligence (AI), Machine Learning (ML), and Deep Learning (DL) are interconnected fields, but they are not the same. AI is a broad concept that refers to machines being able to carry out tasks in a way that we would consider “smart”. It encompasses anything from a computer program playing chess, to a voice-recognition system like Siri or Alexa. ML is a subset of AI, and it involves giving machines access to data and letting them learn for themselves. It’s about creating algorithms that can modify themselves without human intervention to produce desired outcomes by finding patterns in data. DL is a further subset of ML, and it refers to neural networks with three or more layers. These neural networks attempt to simulate the behavior of the human brain—albeit far from matching its ability—allowing it to “learn” from large amounts of data. While a traditional neural network might only have a few layers, a deep network might have dozens or even hundreds.

Here’s how the search results support these definitions:

  • AI is a computer algorithm that exhibits intelligence through decision-making, while ML is an AI algorithm that allows a system to learn from data, and DL is a technique for implementing ML that uses complex neural networks with many layers (GeeksforGeeks).
  • ML and DL are both ways of achieving AI, with DL being a subset of ML that marks a milestone in AI’s evolution by using complex structures like neural networks (TechTarget).
  • DL requires more data points to improve accuracy compared to traditional ML models, which can rely on less data (IBM).
