Analysing the predictions of a CNN-based replay spoofing detection system
(IEEE, 2018-12-18)Playing recorded speech samples of an enrolled speaker - "replay attack" - is a simple approach to bypass an automatic speaker verification (ASV) system. The vulnerability of ASV systems to such attacks has been acknowledged ... -
Analysis and classification of phonation modes in singing
Phonation mode is an expressive aspect of the singing voice and can be described using the four categories neutral, breathy, pressed and flow. Previous attempts at automatically classifying the phonation mode on a dataset ... -
ANALYSIS OF ARTISTIC STYLES IN OIL PAINTING USING DEEP-LEARNING FEATURES
(IEEE, 2020-06)The styles of oil paintings are pre-defined from an aesthetic perspective along with the historical background. With features learnt by Convolutional Neural Networks (CNNs), we construct two style spaces to visualize the ... -
An analysis of customer perception using lexicon-based sentiment analysis of Arabic Texts framework.
(Elsevier, 2024-05-01)Sentiment Analysis (SA) employing Natural Language Processing (NLP) is pivotal in determining the positivity and negativity of customer feedback. Although significant research in SA is focused on English texts, there is a ... -
Analysis of mental and physical disorders associated with COVID-19 in online health forums: a natural language processing study
(BMJ Publishing Group, 2021-11-05)Objectives Online health forums provide rich and untapped real-time data on population health. Through novel data extraction and natural language processing (NLP) techniques, we characterise the evolution of mental and ... -
Analysis of Random Access in NB-IoT Networks with Three Coverage Enhancement Groups: A Stochastic Geometry Approach
(IEEE, 2020-10)NarrowBand-Internet of Things (NB-IoT) is a new 3GPP radio access technology designed to provide better coverage for Low Power Wide Area (LPWA) networks. To provide reliable connections with extended coverage, a repetition ... -
Analysis of the Transmission Performance Limits for a Multi-layer Transmitarray Unit Cell
(IEEE, 2021-09-01)This communication presents a theoretical study that establishes the performance limits for a multi-layer transmitarray unit cell. This is the first study to be applicable to unit cells in which the conducting resonators, ... -
