The aims of this research are to compare the efficiency of imbalance techniques between over sampling and hybrid methods and to compare performance of classification techniques: random forest, logistic regression, and support vector machine, via simulation. The study is given by high imbalanced data and predicted variables which are mostly categorical data. The criteria of the simulation are sample sizes, ratio of the number of predicted variables between categorical variables and continuous variables, and odds ratio. The results shown that balancing data with over sampling method before classify had higher accuracy, sensitivity, and specificity than hybrid method in each sample sizes. In addition, the balanced data classified with random forest had the highest accuracy, sensitivity, and specificity, the average were 0.996, 0.999 and 0.998 respectively. Moreover, logistic regression technique yields less accurate classification when the number of categorical variables is higher. The result of research can be used as a guideline for choosing a data balancing method which appropriate to data conditions in real situations.

The objectives of this research were to design and develop a personalized food recommendation system for psychiatric patients. The proposed system could be used as a tool for staff in hospitals with no nutritionists. The research methodology was based on System Development Life Cycle (SDLC) concept. First, collect patient data in the provinces of Nakhon Ratchasima, Chaiyaphum, Buriram, and Surin and determine the relationship between personal factors, e.g., gender, age, weight, height, waistline, blood type, and life elements. These factors have been taken into account with three mental disorders, namely schizophrenia, depressive, and mental and behavior disorders due to use of alcohol. Patients suffering from these three disorders must be given psychiatric medications that affect their appetite and nutritional needs differently. Finally, the IF-THEN rules were established and applied as conditions for the personalized food recommendation. The proposed system was developed as an easy-to-use web application. The results of the usability assessment indicated that the proposed system was appropriate for recommending personalized foods to psychiatric patients. Furthermore, the user provided the overall satisfaction results of the proposed system at a very good level. This system could be applied to other psychiatric hospitals or network hospitals in the community that are responsible for following up and treating psychiatric patients, but there were neither doctors nor nutritionists to recommend.

This research aims to developed a Content-based image retrieval model for resolve semantic gaps problem where low-level features cannot correctly convey the meaning of images. The result of developed model consists of 3 modules: 1) build the image description set module, it applies a CLIP (Contrastive Language-Image Pre-training) to learn the meaning of images by self-supervised learning from the relationship between images and caption on image encoder and text encoder with cosine similarity before collecting to the image description set and create to an image feature vector. 2) query processing module to learn the meaning of the text and constructs it as a query feature vector, and 3) vectors matching module with similar values between image feature vectors and query feature vectors before sorting by relevance and display the result to the user. The result of image retrieval on the Flickr30k dataset with order-unaware metric had a mean of recall is 0.93 when the result was in the top 10 is very high, but anyway it also found that the main barrier to the accuracy of the results was image variation. When comparing the image retrieval results with the image custom dataset, it was found that the average of recall was in the same direction. And there is no problem that the model's performance is compromised when working with previously unseen data. Demonstrate that the model can retrieve content-based images effectively. It also supports users with search terms in the form of natural language that are based on the meaning of the image rather than the grammar of the language. This impact of results is a guideline for information retrieval in the future.

Suwanee Kulkarineetham, Weeriya Supanich — Thu, 27 Jun 2024 00:00:00 +0700

Community-based tourism focuses on enhancing the value of cultural and natural resources of the community. Tourists get an authentic experience from the local lifestyle and wisdom within the community. Therefore, having an application that recommends tourist spots personalized to individual tourists' needs, and a community tourism management system is essential. This research presents the development of an application platform for an adaptive personalized tourist attraction recommendation system (APTARS). The objective is to create an adaptive personalized tourist attraction recommendation model using a collaborative filtering method and developing cross-platform applications for tourists and entrepreneurs in community-based tourism management on Android and iOS operating systems, developed with React, Node.js, and Flutter, managing databases with MongoDB. The researcher evaluated the performance of the adaptive personalized tourist attraction recommendation model using the Mean Absolute Error value (MAE) and Root Mean Square Error (RMSE). The research findings indicate that the Euclidean distance is the most effective algorithm to measure user similarity for optimal recommendation performance. The appropriate number of neighboring nodes for travel destination recommendation is 25 nodes. The performance evaluation of the application platform by experts is rated as good. User satisfaction assessment of the application platform from a sample group of 40 people, comprising 10 community entrepreneurs and 30 tourists, found that the overall user satisfaction is rated very good (=4.52, S.D.=0.51). The accuracy and functional performance satisfaction had the highest mean (=4.56, S.D.=0.52), followed by satisfaction with the ability to work according to user needs (=4.53, S.D.=0.49), satisfaction with system usage (=4.50, S.D.=0.52), and satisfaction with system and information security (=4.48, S.D.=0.51) respectively.

The research aimed (1) to develop and evaluate an emotion recognition model for Thai speech using artificial neural networks, (2) to enable accurate classification of human emotions, and (3) to bridge communication gaps between computers and users. A dataset from AIResearch.in.th consisting of 27,854 Thai-language sentences categorized into angry, sad, happy, frustrated, and neutral emotions. The Mel Frequency Cepstral Coefficients (MFCC) employed for the speech feature extraction. Data was pre-processed by augmentation techniques, including time stretching, pitch shifting, and noise injection. The pre-processed data trained for artificial neural network models, including a 1-dimensional Convolutional Neural Network (1D CNN), Long Short-Term Memory (LSTM), and a hybrid model (1D CNN and LSTM). Results showed that the hybrid model (1D CNN & LSTM) achieved the highest accuracy of 80.36%, followed by the 1D CNN model (77.52%) and the LSTM model (67.86%).
