Spectral phase estimation based on deep neural networks for single channel speech enhancement
(Journal of Communications Technology and Electronics, 2019-12)
Majority of speech processing algorithms operate only with the spectral magnitude, leaving spectral phase unstructured and unexplored. With recent advancement in deep neural networks (DNNs), the phase processing became ...
Clustering analysis for automatic certification of LMS strategies in a university virtual campus
(IEEE Access, 2019)
In recent years, the use of Learning Management Systems (LMS) has grown considerably.
This has had a strong effect on the learning process, particularly in higher education. Most universities
incorporate LMS as a complement ...
A Nondisturbing Service to Automatically Customize Notification Sending Using Implicit-Feedback
(Scientific Programming, 2019)
This paper addresses the problem of automatically customizing the sending of notifications in a nondisturbing way, that is, by using only implicit-feedback. Then, we build a hybrid filter that combines text mining content ...
Performance analysis of six meta-heuristic algorithms over automated test suite generation for path coverage-based optimization
(Soft Computing, 2019-10)
There exists a direct need to automate the process of test suite generation to get the most optimal results as testing accounts for more than 40% of total cost. One method to solve this problem is the use of meta-heuristic ...
