A multiresolution approach to Recommender systems
(
Association for Computing Machinery, Inc
, 2014 , Conference Paper)
Recommender systems face performance challenges when dealing with sparse data. This paper addresses these challenges and proposes the use of Harmonic Analysis. The method provides a novel approach to the user-item matrix ...
Transformer health index estimation using orthogonal wavelet network
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
The Health Index represents a practical tool that combines the results of operating observations, field inspections, and site and laboratory testing to manage the asset and prioritize investments in capital and maintenance ...
Enhancing the performance of post-failure restoration schemes in multi-tenant networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
Failure in the physical network can cause a temporal or permanent unavailability of some resources, which can lead to a quality of service (QoS) degradation and loss of revenue. While much work has been dedicated to the ...
Directed graph-based wireless EEG sensor channel selection approach for cognitive task classification
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Wireless electroencephalogram (EEG) sensors have been successfully applied in many medical and computer brain interface classifications. A common characteristic of wireless EEG sensors is that they are low powered devices, ...
Global stabilization of autonomous underactuated underwater vehicles in 3D space
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper, global asymptotic stabilization of an autonomous underactuated underwater vehicle (AUUV) is investigated, where the number of actuators of the AUUV is less than the vehicle's degrees of freedom. The model ...
Surviving link failures in multicast VN embedded applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Virtual network embedding (VNE) is defined as the allocation of network resources to multiple virtual networks (VNs) and is recognized to be a challenging task to perform efficiently. Virtual network survivability is a new ...
Histogram-based thresholding in discrete wavelet transform for partial discharge signal denoising
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
White noise is a major interference source that affects the partial discharge (PD) signal detection and recognition. Wavelet shrinkage denoising methods can efficiently reject the white noise embedded in the PD signal ...
Air quality monitoring and prediction system using machine-to-machine platform
(2012 , Conference Paper)
This paper presents an ambient air quality monitoring and prediction system. The system consists of several distributed monitoring stations that communicate wirelessly to a backend server using machine-to-machine communication ...
Classification ensemble to improve medical named entity recognition
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
An accurate Named Entity Recognition (NER) is important for knowledge discovery in text mining. This paper proposes an ensemble machine learning approach to recognise Named Entities (NEs) from unstructured and informal ...
Hybrid intelligent system for disease diagnosis based on artificial neural networks, fuzzy logic, and genetic algorithms
(2011 , Conference Paper)
Disease diagnosis often involves acquiring medical images using devices such as MRI, CT scan, x-ray, or mammograms of patients' organs. Though many medical diagnostic applications have been proposed; finding subtle cancerous ...
