    » Analytic Approach To Face Emotion Recognition With SVM Kernels

    » Omobolaji F. Oyedokun, Elijah O. Omidiora, Ibrahim A. Adeyanju and Fagbola M. Temitayo

    ABSTRACT:

    Face emotion recognition is one of the challenges known with emotion recognition and it has received much attention during the recent years due to its application in different fields. SVM kernels were adopted to increase the robustness of face emotion recognition systems and to identify the most suitable kernel for emotion recognition. This paper uses radial basis function, linear function, sigmoid and polynomial function to identify the six basic emotions and neutral inclusive. In an attempt to achieve this aim the following steps were taken; collection of face emotion images, image pre- processing, features extraction and classification. Face emotion database was created by taken emotional photographs of persons who willing volunteer to help in this paper. The database contains 714 images from 51 persons. However, the photographs were converted from colored images to grayscale images for uniform distribution of colors. Relevant features for classification were extracted from the processed images such as the eyelids, cheeks, nose, eyebrows and lips. Our face emotion database was splitted into two dataset: training set and testing set. SVM classifier used images in the training set to train while images in the testing set were used to test SVM models. The evaluation of the system was performed on MATLAB using classification accuracy and classification time to identify the most suitable kernel for the system. The results obtained shows that sigmoid outperformed other kernels in terms of classification accuracy with overall performance accuracy of 99.33% while polynomial achieved the shortest classification time. In the future, we intend to investigate other classifiers for face emotion recognition and to classify more emotions.

    » A perspective of metacognition in solving math problems in Vietnam secondary schools

    » Nguyen Thi Huong Lan

    ABSTRACT:

    In an effort to innovate teaching and learning process to prepare for a new generation for the demands of the new era, many educators have discovered the value of metacognition. Students will need both mathematical skills and problem-solving skills, therefore, teachers should focus on both math content and thinking processes in students’ math learning. This paper presents the importance of metacognition in solving mathematical problems. A project was conducted for students at the age of thirteen, and the findings suggest that students used four problem-solving steps highlighted by George Polya. However, students feel better when they adjust their thinking processes or use metacognitive skills in the process of solving math problems.

    KEYWORDS:

    Skill, metacognition, problem-solving, mathematical thinking.

    » Samuel Omokanye and Taye Aro

    ABSTRACT:

    Application of data mining algorithms to medical fields have been of interest as it helps patients get access to a better and faster healthcare. In this study, the effect of homogenous ensemble methods of bagging and boosting has been investigated as related to the prediction of the presence or absence of liver diseases. Experimental results show that while bagging and boosting did not improve the accuracy and sensitivity of algorithms in predicting liver disease, Boosting increased the specificity of algorithms.

    ABSTRACT:

    This research formulated and simulated a topology management scheme for wireless mesh network (WMN) in areas of scalability and reliability; considering its vast present limitations in commercialization in many application areas. WMNs framework was devised and OMNeT++network simulator was used to simulate the WMNs model. A research method structure was devised that showed clearly how the project is carried out. An improved model for WMNs that use better approach To Mobile Adhoc Network routing protocol over the existing model was designed and formulated. Pearson Product Moment Correlation (PPMC) was used to find out the correlation between the Scenarios. PPMC produced 0.923 coefficients which showed a high positive correlation between the scenarios indicating that WMNs is reliable and scalable even with additional gateways.

    » A Predictive Model for Tweet Sentiment Analysis and Classification

    » Abdullah K.-K. A., Folorunso S. O., Solanke O. O. and Sodimu S. M.

    ABSTRACT:

    Sentiment analysis over Twitter offers organisations and users a fast and effective way to monitor publics’ feelings towards events especially during crises, hence, motivated much work on twitter data. In this study, predictions on positive, negative and neutral sentiment based on security are analysed. A polarity classification of tweet messages was done with VADER algorithm considering contextual analysis. The analysis was performed by removing stop words in the tweet along with Wordnet lemmatiser for the morphological analysis of words in the features sets. As well as subjected to word sense disambiguation to consider contextual usages of words using a path length corpus based lexicon. Term Frequency (TF) and Term Frequency Inverse Document Frequency (TFIDF) are used as feature extraction from tweets and evaluation of the features reduction was carried out by calculating the accuracy of the predictions on sentiment and tweet messages with Chi-Square to explore the possibly useful features. Finally, validations are done with machine learning models at different sequence to compare the performance between each model.

    KEYWORDS:

    Sentiment analysis, Word sense disambiguation, Natural Language Processing, Chi-Square, VADER.
