Abstract

To date, photograph identification systems for individual marine turtles are focused on the facial profile, and scute patterns on the top of the head, and neck. However, to the best of knowledge, there seems to be no photograph identification system focused on recognising marine turtle species based on characteristics of the carapace. Studies argued that by including more features, such as characteristics of the shell, the systems could enhance its classification accuracy. However, previous works have failed to address why none of them used characteristics of the shell for identifying marine turtle species. In this research, a comprehensive study of the effectiveness of the features extracted, colour, shape, and texture, from the carapace is conducted. Several experiments are carried out using the data extracted to find out the suitable data dimensionality, and the "best" hyper-parameters to train the neural networks. The expectation of this research is that these features can be used to develop a non-intrusive automated system for pattern recognition of marine turtle species using the characteristics of the carapace.

Abstract

Having healthy food and a regular diet are some of the most efficient mechanisms to control chronic diseases such as hypertension and diabetes. The existent systems do not provide mechanisms to allow people in such conditions to easily find restaurants providing suitable food for them. Under these circumstances, this study proposes a design of a conceptual framework for restaurant recommender system to improve people's decision-making process of choosing restaurants providing food according to their health conditions and preferences. The framework includes a user personal profile module, graphical user interface, database, knowledge base, and ontologies containing the restaurant menu items and their respective nutritional information. A prototype system has been developed to test the performance of the framework. The tests show that this framework can be used for the purpose that was conceived.

Abstract

Biologists use a manual sea turtle identification key technique to classify marine turtle species according to their scutes patterns. However, limited research to date has focused on developing a system for recognising marine turtle species. Studies in the field of photograph identification system for individual animals have failed to address why none of them developed a system to categorise marine turtle species. The aim of this research is to develop a hybrid model for pattern recognition of marine turtle species based on the stacked generalisation. The hybrid model consists of two major modules:combination unit, which is the combination of the outcomes of neural network model and C4.5 decision tree model, and meta-learning that uses the neural network to aggregate the results from the combination unit and increases the accuracy of the total classification. Several experiments are carried out, where different parameters influencing the overall performance of modules are investigated. The results showed that the trial-error-test could be used to improve the computational cost and mean absolute error of the stacked generalisation when neural networks are used in both combination unit and meta-learning. Therefore, it can be concluded that the hybrid model is an improvement over the traditional manual method for categorization of marine turtle species.

Abstract

This study aims to incorporate a new service into existing Moodle Core Services for student's usage data retrieval. This service can ease the pre-processing in EDM and provide a generic mechanism for data portability. The proposed method expects to reduce the data pre-processing time and enhance the interoperability in Moodle.
