    Investigating the effects of Data Normalization on Predictive Models
    (Faculty of Communication and Information Sciences, University of Ilorin, Ilorin., 2017) Ajiboye, A. R; Ajiboye, I. K; Salihu, S. A; Tomori, A. R
    The creation of predictive model using a supervised learning approach involves the task of building a model of the target variable as a function of the explanatory variables. Before a model is created, it is necessary to put the data in a suitable format. Studies have shown that normalization of data is crucial to descriptive mining as it improve the accuracy and efficiency of mining algorithms. However, in the case of prediction, it is not in all cases that predictive models are created from normalized data. This paper presents the experimental results of investigating the effect of normalizing the input variables on models created for prediction purposes. Experiments are conducted for the creation of predictive models from two different sets of equal size of data using neural network techniques. The trained network models created with the same architecture and configurations are subsequently simulated using a set of untrained data. The evaluation results and the comparison of the models created through the two data sets of different format reveals that, the model created from a normalized data appears to be more accurate as a decrease in error by 0.003 are consistently recorded. The model also converges much earlier than the model created from the data that does not undergo any form of normalization.

    Leveraging Knowledge Assets in Tertiary Institutions using Information and Communication Technologies
    (2015) Salihu, S. A; Mejabi, O.V; Adebimpe, L.A
    The contribution of knowledge asset to organizational effectiveness cannot be overemphasized. However, Information and Communication Technology (ICT) has been identified as a veritable catalyst for leveraging knowledge asset. The adoption of ICT as veritable tools that contribute immensely to the achievement of feats in the educational sector has been lauded. It has served as an eye opener for emerging innovation and landmark discovery, provided an impetus for transmission of knowledge to bridge the gap posed by inadequacy of delivery processes etc. The beautiful contributions of ICT to knowledge acquisition notwithstanding, it is not iron clad to ward off challenges of all kinds, hence; the need to examine the level of applicability of ICT to knowledge management with a view to unveiling the possible real challenges that might hinder its adaptability and to appraise its suitability that would make for full scale adoption.
