Frequent itemset mining is a fundamental step in analysis of big data where correlation among the raw data in deemed necessary. In modern era the amount of data available for processing has grown exponentially, making it a stepper task for mining algorithms to provide solution in a timely manner. The software implementations are normally not efficient in handling such datasets thus focus on parallel...
Glaucoma is a lifetime medical condition which might results in the deprivation of visual sense from an individual permanantly if remained untreated and undiagnosed at early phase. Some structural changes are observed by ophthalmologists using state of art biomedical imaging techniques i.e. Fundscopy and optical coherence tomography in retinal layers and optic nerve head of person effected by glaucoma...
A complete decoder is one that guarantees to decode a received vector to its nearest codeword. For the design of an efficient complete decoding algorithm, storage demand and decoding complexity are two essential factors. Along this consideration, the Zero-Guards algorithm provides a significant improvement as the number of vectors required to be stored has been made much less than what is required...
In this paper, two new kernel adaptive algorithms are proposed. An approximation is used in order to derive the pseudo kernel affine projection algorithm and the pseudo kernel proportionate affine projection algorithm, respectively. The computational efficiency and performance of the proposed algorithms is verified for a nonlinear system identification application.
Several methods for capturing motion data from single video have been reported in computer vision literature, and most of them deal with stationary background. The problem becomes more complex and challenging in a moving scene where traditional background subtraction algorithms often fail. We require robust algorithms for marker-less tracking of human body's movements and for extracting motion information...
Square-root algorithms have use in certain areas of digital signal processing. However, they are characterized as being non-linear in nature and hence their analysis is not straight-forward. This paper examines two such algorithms and shows that the convergence is guaranteed provided the closed-loop discrete-time system is stable, but that the upper limit on stability is determined by the values of...
