Pattern recognition is the ability to identify and understand regularities or trends in data. This process involves recognizing shapes, sounds, or sequences that follow a specific arrangement. It is a fundamental skill used in various fields, including artificial intelligence, machine learning, and data analysis, where computers are trained to detect patterns in large datasets. In everyday life, humans naturally use pattern recognition to make sense of their surroundings. For example, we can recognize faces, read text, or predict the weather based on past experiences. This cognitive ability helps us navigate the world and make informed decisions based on familiar cues and trends.
