what is pattern recognition in computer science

In 1997, IBM's Deep Blue used its ability to recognize patterns of play to defeat world chess champion Garry Kasparov.

Combined with computer vision, it has been applied for building 3D models from images. A new sample is then assigned to the class which occupies the portion of space in which the sample is located. Significant advances have been made in video-based face modeling/tracking, recognition, and system integration [10, 7]. Golden, in International Encyclopedia of the Social & Behavioral Sciences, 2001, Statistical pattern recognition is concerned with the problem of designing machines that can classify complex patterns. This is a great place for AI to step in and be able to do the task much faster and much more efficiently than a human worker who is going to get tired out or bored. Moreover complications arise due to variations in pose, illumination and facial expression (Wang et al., 2002). Of course, it is possible to combine bottom-up and top-down processing. The power of this pattern is that we’re enabling machines to do the thing that our brains seem to do so easily: identify what we’re perceiving in the real world around us. Panel 12 shows a focal shape inflection in the Alzheimer's patients relative to normal elderly subjects of the same age, and a statistically significant tissue loss in the isthmus (the second sector, when the structure is partitioned into fifths). Cancer subtypes identification plays an important role in personalized medicine framework. The first component is a feature selection and extraction stage where critical informational features about the data are identified for classification purposes. It is closely related to machine learning, and also …

Paul M Thompson, Arthur W Toga, in Handbook of Medical Imaging, 2000. Stages in pattern recognition may involve measurement of the object to identify distinguishing attributes, extraction of features for the defining attributes, and comparison with known patterns to determine a match or mismatch. 10 and 11; Thompson et al., 1998a; Narr et al., 1999). There could even be the potential to use this in areas such as vehicle repair where the machine can listen to different sounds being made by an engine and tell the operator of the vehicle what is wrong and what needs to be fixed and how soon. This is something already heavily in use by the video game industry. As we have seen, by averaging contours derived manually from an image database, structural abnormalities associated with Alzheimer's disease and schizophrenia were identified (Figs. Pattern generalisation is spotting things that are common between patterns.

Pattern recognition is one of the four cornerstones of Computer Science. Pattern Recognition is a mature and fast developing field, which forms the core of many other disciplines such as computer vision, image processing, clinical diagnostics, person identification, text and document analysis. Kernels and in particular SVMs have been widely applied in this context since the ‘90 s (Osuna et al., 1997), collecting many successes both in the specific topics of face detection (Li et al., 2000a; Ai et al., 2001; Ng and Gong, 1999, 2002; Huang et al., 1998) and face authentications (Tefas et al., 2001; Jonsson et al., 2002).

This is called supervised pattern recognition or supervised learning. This measure penalizes curve shapes (1) that are too bent or stretched, (2) that fail to overlap the diffused edge image, or (3) that are unlikely based on a statistical distribution of normal corpus callosum shapes.

Davidson, in Comprehensive Chemometrics, 2009. , these characteristics are known as patterns.
