How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
I am a PhD student in the Computing Science Dept. at Simon Fraser University, Canada. I received my M.Sc. degree from the Computer and Systems Engineering Department, Alexandria University, Egypt where I worked as RA/TA. I received my Bachelor's Degree from the Computer and Communications Department in July 2013. I graduated with Distinction with Honor and I ranked first in my class. My main research interests include Cognitive Radio Networks, Spectrum Sensing, Machine Learning, Multimedia Streaming in VR/AR and Artificial Intelligence.
Machine based text comprehension has always been a significant research field in natural language processing. Once a full understanding of the text context and semantics is achieved, a deep learning model can be trained to solve a large subset of tasks, e.g. text summarization, classification and question answering. In this paper we focus on the qu...
One of the main characteristics in cognitive radios is situation awareness. By classifying the modulation schemes used in surrounding transmissions, a secondary user (SU) can identify the existing users in the system and adjust his/her transmission parameters accordingly. In this paper, we propose a multi-task learning (MTL) approach to recognize t...
One of the main challenges in cognitive radios is spectrum sensing. Cooperative spectrum sensing scheme among mobile users can be used to determine the usage profile of wide spectrum bands in a large geographical region. In a large mobile crowdsensing environment, the key step is to assign the sensing task among mobile users to maximize the spectru...
