Pattern Recognition is a mature but exciting and fast developing field, which underpins developments in cognate fields such as computer vision, image processing, text and document analysis and neural networks. It is closely akin to machine learning, and also finds applications in fast emerging areas It is closely akin to machine learning, and also finds applications in fast emerging areas such as biometrics, bioinformatics, multimedia data analysis and most recently data science. The journal Pattern Recognition was established some 50 years ago, as the field emerged in the early years of computer science.

Author: Zee Gimon. Have you ever stopped to think about how your brain assesses the world around you? What is pattern recognition in general? While we hear this term a lot in the IT world, it originally comes from cognitive neuroscience and psychology. Pattern recognition is a cognitive process that happens in our brain when we match some information that we encounter with data stored in our memory. There are also pattern recognition receptors PRR in our body - macrophages, monocytes, etc.

The course considers foundational and advanced pattern recognition methods for classification tasks in signals and data. We take a Bayesian approach in this course. Simple example applications can be a digit recognition task, or automatic word recognition task. A complex application can be in medical field, such as recognition of disease from patient data.

By introducing the methods of machine learning into the density functional theory, we made a detour for the construction of the most probable density function, which can be estimated by learning relevant features from the system of interest.


Because nearly all practical or interesting pattern recognition problems are so hard that we cannot guess classification decision ahead of time.


Learning and Adaptation

I completed my Ph. I have broad interest in machine learning and computer vision. Specifically, my research focuses on supervised and unsupervised deep representation learning with applications to computer vision, audio recognition, and text processing, using graphical models that are invariant to many factors of variation for robust perception from complex and multimodal data.

As stated earlier, ANN is completely inspired by the way biological nervous system, i. The most impressive characteristic of the human brain is to learn, hence the same feature is acquired by ANN. Basically, learning means to do and adapt the change in itself as and when there is a change in environment. ANN is a complex system or more precisely we can say that it is a complex adaptive system, which can change its internal structure based on the information passing through it.

Pattern Recognition is a useful tool for deciphering movement intent from myoelectric signals. Recognition paradigms must adapt with the user in order to be clinically viable over time. Most existing paradigms are static, although two forms of adaptation have received limited attention. Supervised adaptation can achieve high accuracy since the intended class is known, but at the cost of repeated cumbersome training sessions. Unsupervised adaptation attempts to achieve high accuracy without knowledge of the intended class, thus achieving adaptation that is not cumbersome to the user, but at the cost of reduced accuracy. This study reports a novel adaptive experiment on eight subjects that allowed repeated measures post-hoc comparison of four supervised and three unsupervised adaptation paradigms. Most unsupervised adaptation paradigms provided smaller reductions in error, due to frequent uncertainty of the correct class.
