Collaborative filtering are recommender systems algorithms that provide personalized recommendations to users in various online environments such as movies, music, books, jokes and others. There are many such recommendation algorithms and, regarding... Read More about Fast and accurate evaluation of collaborative filtering recommendation algorithms.

Problem classification for tailored help desk auto replies (2022)
Conference Proceeding
Nicholls, R., Fellows, R., Battle, S., & Ihshaish, H. (2022). Problem classification for tailored help desk auto replies. In E. Pimenidis, P. Angelov, C. Jayne, A. Papaleonidas, & M. Aydin (Eds.), Artificial Neural Networks and Machine Learning – ICANN 2022 (445-454). https://doi.org/10.1007/978-3-031-15937-4_37

IT helpdesks are charged with the task of responding quickly to user queries. To give the user confidence that their query matters, the helpdesk will auto-reply to the user with confirmation that their query has been received and logged. This auto-re...

An integrated online/offline social network-based model for crowdfunding support in developing countries: The case of Nigeria (2022)
Journal Article
Ogwu, K., Hickey, P., Okeke, O. J. P., Haque, A. U., Pimenidis, E., & Kozlovski, E. (2022). An integrated online/offline social network-based model for crowdfunding support in developing countries: The case of Nigeria. Sustainability, 14(15), e9333. https://doi.org/10.3390/su14159333

This paper is one of the first attempts to address the fundamental barriers to the adoption of online crowdfunding mechanisms in a developing country by offering a new online/offline fundraising model. The focus is on Nigeria as a typical example of... Read More about An integrated online/offline social network-based model for crowdfunding support in developing countries: The case of Nigeria.

An explainable semi-personalized federated learning model (2022)
Journal Article
Demertzis, K., Iliadis, L., Kikiras, P., & Pimenidis, E. (2022). An explainable semi-personalized federated learning model. Integrated Computer-Aided Engineering, 29(4), 335-350. https://doi.org/10.3233/ICA-220683

Training a model using batch learning requires uniform data storage in a repository. This approach is intrusive, as users have to expose their privacy and exchange sensitive data by sending them to central entities to be preprocessed. Unlike the afor...

Supporting patient nutrition in critical care units (2022)
Conference Proceeding
Soomro, K., Pimenidis, E., & McWilliams, C. (2022). Supporting patient nutrition in critical care units. In Engineering Applications of Neural Networks: EANN 2022: Engineering Applications of Neural Networks (128-136). https://doi.org/10.1007/978-3-031-08223-8_11

Critical Care Unit (CCU) patients often benefit from being referred to dietitians for various reasons. This can help improve recovery time, resulting in more effective utilisation of valuable resources within the NHS (National Health Service) in the...

Design issues of a pan European smart cross border ‘dream like’ e-Gov primary healthcare medical service (2022)
Journal Article
Sideridis, A. B., Pimenidis, E., Protopappas, L., Yialouris, C., Maragkopoulos, V. -. A., & Chatziandreou, A. (2022). Design issues of a pan European smart cross border ‘dream like’ e-Gov primary healthcare medical service. International Journal of Electronic Governance, 14(1-2), 172-194. https://doi.org/10.1504/IJEG.2022.123252

The EU Commission has provided its members regulation and systems for the development of services enabling cross border transactions, but the full practice of these is modest. An exception can be made in cases where there’s personal data processing.... Read More about Design issues of a pan European smart cross border ‘dream like’ e-Gov primary healthcare medical service.

Variational restricted Boltzmann machines to automated anomaly detection (2022)
Journal Article
Demertzis, K., Iliadis, L., Pimenidis, E., & Kikiras, P. (2022). Variational restricted Boltzmann machines to automated anomaly detection. Neural Computing and Applications, 34, 15207–15220. https://doi.org/10.1007/s00521-022-07060-4

Data-driven methods are implemented using particularly complex scenarios that reflect in-depth perennial knowledge and research. Hence, the available intelligent algorithms are completely dependent on the quality of the available data. This is not po...
