Research project: Detection of Cardiac Arrhythmia Patterns by Adaptive Analysis |
<< TO BE UPDATED, PLEASE VISIT AGAIN>> |
Th adaptive technology makes use of a neural models with error back-propagation and explores the gradient-decent method for sample-by-sample adaptation. The implementations of the higher-order neural models have been developed in Python language. |
There are several types of adaptive methodologies, such as multilayer neural networks, higher-order neural networks, adaptive self-organized maps, and adaptive radial basis function neural networks, among others. |
Pattern recognition is one of the beneficial fields when we consider the development of adaptive methodologies, because of its multiple applications in several knowledge areas. Development of new mathematical models stimulates the research community to creating the new technologies for recognizing behavioral patterns in chaotic systems applied to diagnosing various types of diseases such as: Parkinson’s, cancer, lung and heart disease, to name a few [1]. |
In several cases it is necessary to use vision systems, since the components that are analyzed can present defects which are not visible to the human eye; so it is necessary to implement technologies to improve processes and subprocesses, such as the inspection and classification of parts, which contain some damage or a specific characteristic, for example, such as a small scratch [2]. |

The
adaptive threshold
technique is one of the more
significant part of the detection method. The
adaptive threshold
is performed by using a
pair of threshold limits
called the upper
limited threshold
and the lower
limited threshold.
The adaptive threshold is generally determined based on an amount of most recent data. This work uses a pair of thresholds (upper and lower thresholds), which are initialized in regard to the maximum value attained by the current frame. |
