Fault of Our Stars: Behavioral Drivers of Rating-Sentiment Incongruence
Ramanaish Abaiyan, Ruththiragayan Sutharsan, Kusal Amantha +7
When people share experiences online, they often express thoughts in two ways: a star rating and a written review. In sentiment analysis, ratings are widely used as convenient weak…
The Remittance Blueprint: Data-driven Intelligence for Sri Lanka
Dhinanjaya Fernando, Dinura Ginige, Kalana Lakshan +6
This study analyzes Sri Lankan migration and remittances over 32 years (1994-2025). Using a 384-month harmonized dataset, we apply exploratory data analysis, stationarity corrected…
TopoCast: A Topological Fidelity Framework for Evaluating Transformer-Based Time Series Forecasting
Sandeepa Weerasekara, Sandareka Wickramanayake
Deep learning-based models have achieved state-of-the-art performance in Time Series Forecasting (TSF), yet their evaluation remains dominated by pointwise error metrics such as Me…
When Prices Double in a Week: Forecasting of Agricultural Volatility in Import-Isolated Markets
Ranuga Weerasekara, Heshan Nethmina, Manuja Ranathunga +6
Vegetable prices in Sri Lanka are highly volatile because the market is largely import-isolated, so supply disruptions quickly drive prices up. This study develops a machine learni…
