ASEM: Enhancing Empathy in Chatbot through Attention-based Sentiment and Emotion Modeling
Omama Hamad, Ali Hamdi, Khaled Shaban
Effective feature representations play a critical role in enhancing the performance of text generation models that rely on deep neural networks. However, current approaches suffer…
GCCN: Global Context Convolutional Network
Ali Hamdi, Flora Salim, Du Yong Kim
In this paper, we propose Global Context Convolutional Network (GCCN) for visual recognition. GCCN computes global features representing contextual information across image patches…
Signature-Graph Networks
Ali Hamdi, Flora Salim, Du Yong Kim +1
We propose a novel approach for visual representation learning called Signature-Graph Neural Networks (SGN). SGN learns latent global structures that augment the feature representa…
MARL: Multimodal Attentional Representation Learning for Disease Prediction
Ali Hamdi, Amr Aboeleneen, Khaled Shaban
Existing learning models often utilise CT-scan images to predict lung diseases. These models are posed by high uncertainties that affect lung segmentation and visual feature learni…
Spatiotemporal Data Mining: A Survey on Challenges and Open Problems
Ali Hamdi, Khaled Shaban, Abdelkarim Erradi +3
Spatiotemporal data mining (STDM) discovers useful patterns from the dynamic interplay between space and time. Several available surveys capture STDM advances and report a wealth o…
Drone-as-a-Service Composition Under Uncertainty
Ali Hamdi, Flora D. Salim, Du Yong Kim +2
We propose an uncertainty-aware service approach to provide drone-based delivery services called Drone-as-a-Service (DaaS) effectively. Specifically, we propose a service model of…
