A Graph-based Method for Session-based Recommendations
Marina Delianidi, Michail Salampasis, Konstantinos Diamantaras +3
We present a graph-based approach for the data management tasks and the efficient operation of a system for session-based next-item recommendations. The proposed method can collect…
Student Performance Prediction Using Dynamic Neural Models
Marina Delianidi, Konstantinos Diamantaras, George Chrysogonidis +1
We address the problem of predicting the correctness of the student's response on the next exam question based on their previous interactions in the course of their learning and ev…
Sparse Antenna Array Design for MIMO Radar Using Softmax Selection
Konstantinos Diamantaras, Zhaoyi Xu, Athina Petropulu
MIMO transmit arrays allow for flexible design of the transmit beampattern. However, the large number of elements required to achieve certain performance using uniform linear array…
Learning to Select for MIMO Radar based on Hybrid Analog-Digital Beamforming
Zhaoyi Xu, Fan Liu, Konstantinos Diamantaras +2
In this paper, we propose an energy-efficient radar beampattern design framework for a Millimeter Wave (mmWave) massive multi-input multi-output (mMIMO) system, equipped with a hyb…
