Automated Single-Label Patent Classification using Ensemble Classifiers

no code implementations3 Mar 2022 Eleni Kamateri, Vasileios Stamatis, Konstantinos Diamantaras, Michail Salampasis

Therefore, there is a need for this code assignment manual task to be supported or even fully automated by classification systems that will classify patent applications, hopefully with an accuracy close to patent professionals.

Student Performance Prediction Using Dynamic Neural Models

1 code implementation1 Jun 2021 Marina Delianidi, Konstantinos Diamantaras, George Chrysogonidis, Vasileios Nikiforidis

Since the next response is a function of the knowledge state of the student and this, in turn, is a function of their previous responses and the skills associated with the previous questions, we propose a two-part network architecture.

Learning to Select for MIMO Radar based on Hybrid Analog-Digital Beamforming

no code implementations18 Jan 2021 Zhaoyi Xu, Fan Liu, Konstantinos Diamantaras, Christos Masouros, Athina Petropulu

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 hybrid analog-digital (HAD) beamforming structure.
