== Artificial intelligence vs. machine learning ==

Artificial intelligence (AI) is a field of computer science dedicated to creating systems that perform tasks associated with human intelligence, such as reasoning, problem-solving, and perception. The term was first proposed by John McCarthy in 1956 during the Dartmouth Workshop.<ref>McCarthy, J., Minsky, M. L., Rochester, N., & Shannon, C. E. (1955). A Proposal for the Dartmouth Summer Research Project on Artificial Intelligence.</ref> Machine learning (ML) is a specific subfield of AI. It involves the use of statistical techniques and algorithms that allow computers to "learn" from data without being explicitly programmed for every possible scenario.<ref>Samuel, A. L. (1959). Some Studies in Machine Learning Using the Game of Checkers. IBM Journal of Research and Development.</ref>

Early AI research focused on symbolic logic and "expert systems," which relied on hard-coded rules provided by human specialists. These systems followed "if-then" logic to reach conclusions. In contrast, machine learning shifted the focus toward pattern recognition. Instead of following a rigid script, an ML model identifies statistical regularities in large datasets to make predictions or decisions.<ref>Mitchell, T. (1997). Machine Learning. McGraw Hill.</ref>

=== Relationship between the fields ===

The relationship between these two areas is often described as a series of nested circles. Artificial intelligence is the outermost circle, encompassing all attempts to mimic human thought. Machine learning sits inside that circle, representing the specific approach of using algorithms to parse data. Within machine learning is another subset called deep learning, which utilizes multi-layered neural networks to process information in a manner inspired by biological brains.<ref>Goodfellow, I., Bengio, Y., & Courville, A. (2016). Deep Learning. MIT Press.</ref>

A primary distinction lies in how the systems handle new information. A traditional AI system based on rules cannot adapt if it encounters a situation not covered by its code. A machine learning system, however, adjusts its internal parameters when it receives new training data. For example, a rule-based AI for medical diagnosis might follow a fixed flowchart of symptoms. A machine learning version would analyze thousands of previous patient records to identify which combination of symptoms most frequently indicates a specific condition.

While AI includes concepts like robotics and natural language processing that do not always require learning, machine learning has become the dominant method for achieving modern AI milestones. Computer vision, speech recognition, and recommendation engines all rely on machine learning techniques to function effectively in real-world environments.
