ObjectivesTo describe the nature of geriatric medical admissions to teaching hospitals in three countries in Africa (Nigeria, Sudan, Tanzania) and compare them with data from the United Kingdom.
DesignCross‐sectional cohort study.
SettingFederal Medical Centre, Idi‐Aba, Abeokuta, Nigeria; Soba University Hospital, Khartoum, Sudan; Kilimanjaro Christian Medical Centre, Moshi, Tanzania; and North...
This paper investigates the performance of conjugate gradient algorithms with sliding-window approach for training multilayer perceptron (MLP). Online learning is implemented when the system under investigation is time varying or when it is not convenient to obtain a full history of offline data about the system variables. Sliding window framework is proposed to combine the robustness of offline learning...
The paper investigates the enhancement in various conjugate gradient training algorithms applied to a multilayer perceptron (MLP) neural network architecture. The paper investigates seven different conjugate gradient algorithms proposed by different researchers from 1952-2005, the classical batch back propagation, full-memory and memory-less BFGS (Broyden, Fletcher, Goldfarb and Shanno) algorithms...
