Pattern recognition is an area of study within machine learning and artificial intelligence that focuses on recognizing patterns and regularities in data in order to make predictions or classifications. This field encompasses a wide range of techniques, including statistical methods, neural networks, and deep learning algorithms. Pattern recognition is used in a variety of applications, such as image and speech recognition, medical diagnosis, and financial forecasting. The ultimate goal of pattern recognition is to develop algorithms that can automatically identify patterns in data and make accurate predictions or classifications based on those patterns.
