- Biography
Abeysinghe’s research framework includes social media analytics with a concentration in Natural Language Processing used in classifying tweets. His work explores the domains of Artificial Intelligence and Expert Systems. That includes: Neural Language Model, Recurrent Neural Networks in Language and Artificial General Intelligence.
Abeysinghe’s ongoing research has been testing different models of Deep Neural Networks such as Recurrent Neural Networks (RNN), Gated Recurrent Units (GRUs), Long Short Term Memory (LSTM) models, Convolutional Neural Networks (CNN) and Fully Convolutional Neural Networks (FCNNs). He then gauges the behavior and performance in different environmental conditions.
During his time as a lecturer at the University of Peradeniya, Abeysinghe taught Structure Oriented Programming, Image Processing Practical Data Structures and Computer Graphics.
