Currently climate change is one of the major problems encountered due to the climatic controls interacting in various intensities and in different combinations. The proposed system includes mechanism that accepts/processes ...
Analysis of key randomness in improved one-time pad cryptography
; Gerardo, Bobby D. ; Medina, Ruji P. (IEEE Computer Society, 2019-12-09)
; Medina, Ruji P. (IEEE Computer Society, 2019-12-09)
In cryptography, one-time pad (OTP) is claimed to be the perfect secrecy algorithm in several works if all of its features are applied correctly. Its secrecy depends mostly on random keys, which must be truly random and ...
Modified adaptive synthetic SMOTE to improve classification performance in imbalanced datasets
Gameng, Hazel A. ; Gerardo, Bobby D. ; Medina, Ruji P. (Institute of Electrical and Electronics Engineers Inc., 2020-06-16)
; Gerardo, Bobby D. ; Medina, Ruji P. (Institute of Electrical and Electronics Engineers Inc., 2020-06-16)
The oversampling technique in the data preprocessing has been utilized to mitigate the imbalanced data problem in the real research scenario. This imbalance may reduce the ability of classification algorithms to recognize ...
