Imputation of Rainfall Data Using the Sine Cosine Function Fitting Neural Network
Chan Chiu, Po; Selamat, Ali; Krejcar, Ondrej; Kuok Kuok, King; Herrera-Viedma, Enrique; Fenza, Giuseppe (International Journal of Interactive Multimedia and Artificial Intelligence (IJIMAI), 09/2021)Missing rainfall data have reduced the quality of hydrological data analysis because they are the essential input for hydrological modeling. Much research has focused on rainfall data imputation. However, the compatibility ... -
Performance and Convergence Analysis of Modified C-Means Using Jeffreys-Divergence for Clustering
Seal, Ayan; Karlekar, Aditya; Krejcar, Ondrej; Herrera-Viedma, Enrique (International Journal of Interactive Multimedia and Artificial Intelligence (IJIMAI), 12/2021)The size of data that we generate every day across the globe is undoubtedly astonishing due to the growth of the Internet of Things. So, it is a common practice to unravel important hidden facts and understand the massive ... -
S-Divergence-Based Internal Clustering Validation Index
Kumar Sharma, Krishna; Seal, Ayan; Yazidi, Anis; Krejcar, Ondrej (International Journal of Interactive Multimedia and Artificial Intelligence, 12/2023)A clustering validation index (CVI) is employed to evaluate an algorithm’s clustering results. Generally, CVI statistics can be split into three classes, namely internal, external, and relative cluster validations. Most ...
