Initialization and Estimation of Weights and Bias using Bayesian Technique

Oryiema Robert, David Angwenyi, Nyogesa Achiles & Jacob On'gala · Asian Journal of Probability and Statistics · 2022

Researches on artificial neural network models have shown that the method used to initialize and estimate weights and bias always determines the rate at which the network will converge and how efficient the model will perform. Although there are several methods that can be used t...

Arima Model for Forecasting of Monthly Rainfall and Temperature in the Lake Victoria Basin

Oryiema Robert · Asian Journal of Probability and Statistics · 2022

The rise in global temperature which is global warming has lead to erratic and disruptive weather pattern in several regions of the world including the area surrounding the Lake Victoria basin. Likewise, economic activities associated with Lake Victoria and its Basin such as agri...

Extended Ensemble Filter for High-dimensional Nonlinear State Space Models

Oryiema Robert, David Angwenyi & Kevin Midenyo · Journal of Advances in Mathematics and Computer Science · 2021

There are several functional forms for non-linear dynamical filters. Extended Kalman filters are algorithms that are used to estimate more accurate values of unknown quantities of internal dynamical systems from a sequence of noisy observation measured over a period of time. This...
