    Behavioural Akademic Self-Esteem (BASE) has been used with children of preschool, elementary; and junior high school classes both individually and in groups.In this study,BASE is used to estimate the factor structures and determine the levels of academic self-esteem of the student.The current practice of the existing system using BASE scale may be scored by hand or by computer based on the rigid crisp values to represent rating number one through five.Since BASE requires the ability for estimating the factor structure and also the ability to exlpain how the conclusion is derived,therefore artificial intelligent techniques that are required to perform BASE must be able to perform estimation and provide reasoning.For this purpose fuzzy logic and expert system have been integrated in a web-based environment to demonstrate the use of hybrid system on BASE factor structure and levels of academic self-esteem.For each BASE factor, the sub score is provided based on the classifications of Academic Self-Esteem and their respective ranges.In FuzzyXteem,users in particular teachers, counselors, or parent are allowed to measure students' self-esteem at early age using real time computation.FuzzyXteem facilitates user by automatically evaluating BASE factors and help the user diagnoses their students' level of academic self-esteem in 3 ratings:low,moderate and high.It is also able to provide explanation and describe how the conclusion can be derived.The system has been successfully tested by the counselors and conforms to the BASE factor rating scale and sub-scores.FuzzyXteem can be use as an aid to decision making in improving a person's self esteem, and indirectly increases an individual for productivity.The same system functions can be applied to business organization for managing and improving the organizations performance

    In Malaysia, a cooling system is very efficient in reducing the heat from outside temperature. Normally, for those who afford, the best equipment will be utilized to make homes in a cool and comfort temperature. This may take an equipment such as air-conditioner or super insulation to their house. However, those equipments are costly for their installation, maintenance and energy. In this study, we propose a design of roof sprinkler cooling system using fuzzy logic (FL). The water sprinkler works by triggering the controller to open the valves to release and spray water. FL could benefit the cooling system by intelligently controlling the actual water quantity based on the observed daily weather condition captured from a sensor. This technique is the key approach to saving both water and energy. The system has been simulated and tested accordingly with a number of conditions and parameters, and it has been shown that the proposed design is feasible and practical to be implemented

    Improving generalization of neural network using length as discriminant

    Get PDF
    This paper discusses the empirical evaluation of improving generalization performance of neural networks by systematic treatment of training and test failures. As a result of systematic treatment of failures, a discrimination technique using LENGTH was developed. The experiments presented in this paper illustrate the application of discrimination technique using LENGTH to neural networks trained to solve supervised learning tasks such as the Launch Interceptor Condition 1 problem. The discriminant LENGTH is used to discriminate between the predicted "hard-to-learn" and predicted "easy-to-learn" patterns before these patterns are fed into the networks. The experimental results reveal that the utilization of LENGTH as discriminant has improved the average generalization of the networks increased

    Investigating the effect of data representation on neural network and regression

    In this research the impact of different data representation on the performance of neural network and regression was investigated on different datasets that has binary or Boolean class target.In addition, the performance of particular predictive data mining model could be affected with the change of data representation.The seven data representations that have been used in this research are As_Is, Min Max normalization, standard deviation normalization, sigmoidal normalization, thermometer representation, flag representation and simple binary representation.Moreover, all data representations have been applied on two datasets which are Wisconsin breast cancer and German credit dataset. As a result, the neural network performance is better than logistic regression on both datasets if we exclude the thermometer and flag representations.For datasets having a binary or Boolean target class, flag or thermometer binary representation is recommended to be used if logistic regression analysis is performed. Meanwhile, As_is representation, min max normalization,standard deviation normalization or sigmoidal normalization is recommended for neural network analysis on datasets having binary or Boolean target class

    Fuzzy logic approach to corporate strategy mapping

    Get PDF
    Corporate strategy mapping involves an analysis of company's present situation based on strategic factors known as SWOT factors that represent Strengths, Weaknesses, Opportunities, and Threats. The company survival analysis aims to forecast appropriate strategies to undertake.For this purpose, Internal-External Matrix (I-E Matrix) is used to map a company's external and internal factors' scores to determine the overall corporate strategy of a company. Based on both scores, IE matrix recommends a company with three types of strategy; Grow and Build, Hold and Maintain, and Harvest and Divest. In allocating the strategies, there are regions whereby the coordinates of mapped IFA and EFA scores are not able to immediately indicate the appropriate strategy to be undertaken by a company.When such cases arise, an analyst opinion is required in order to determine which strategy implementation is most appropriate. Different analyst may provide different opinion based on his or her assumption, `market driven' or `resource-based'. There is no exact solution for the scores that fall in the ambiguous regions. As a solution, one possible approach is to integrate Fuzzy Logic technique with I-E Matrix in producing the automatic strategy formulation.This is due to the fact that Fuzzy Logic has shown to have ability to improve the intelligence of systems on uncertain, imprecise and noisy environment. In this study, Fuzzy Logic has been developed and tested on real cases data.The result shows that the proposed technique is able to forecast the strategic choice for the ambiguous locations that exists in the company
