Pattern recognition is the process of identifying regularities and relationships within data using machine learning algorithms. It involves classifying and categorizing data based on observed patterns, enabling systems to make predictions, categorize information, and improve decision-making. Classification: Based on identified patterns, data is categorized into predefined or learned classes. Machine Learning: Pattern recognition relies on algorithms, often within machine learning frameworks, to automatically detect patterns and relationships. Supervised vs. Unsupervised Learning: Pattern recognition can employ supervised methods (using labeled data for training) or unsupervised methods (discovering patterns without prior labeling).
