The Emergence Of The Non-Aligned Foreign Policy Of Burma From The End Of The Second World War To Bandung Conference, Aung Kyaw Min
Chulalongkorn University Theses and Dissertations (Chula ETD)
Burma has been practicing non-aligned foreign policy since its independence. Most of the literature studied on Burma's foreign policy argued that Burma's non-aligned foreign policy was initiated around 1950. As Burma became a colony under the British Empire from 1886 to 1948, the experience of colonialism might also play an essential role in foreign relations in Burma. After independence, Burma also faced numerous challenges, such as insurgency problems. Therefore, the primary objective of this study is to examine the emergence of the ideological foundation of the non-aligned foreign policy of Burma after the Second World War. Moreover, this study will …

A Comparison Of Imbalanced Data Handling Methods For Pre-Trained Model In Multi-Label Classification Of Stack Overflow, Arisa Umparat
A Comparison Of Imbalanced Data Handling Methods For Pre-Trained Model In Multi-Label Classification Of Stack Overflow, Arisa Umparat
Chulalongkorn University Theses and Dissertations (Chula ETD)
Tag classification is essential in Stack Overflow. Instead of combining through pages or replies of irrelevant information, users can easily and quickly pinpoint relevant posts and answers using tags. Since User-submitted posts can have multiple tags, classifying tags in Stack Overflow can be challenging. This results in an imbalance problem between labels in the whole labelset. Pretrained deep learning models with small datasets can improve tag classification accuracy. Common multi-label resampling techniques with machine learning classifiers can also fix this issue. Still, few studies have explored which resampling technique can improve the performance of pre-trained deep models for predicting tags. …
An Application Of Reinforcement Learning To Credit Scoring Based On The Logistic Bandit Framework, Kantapong Visantavarakul
An Application Of Reinforcement Learning To Credit Scoring Based On The Logistic Bandit Framework, Kantapong Visantavarakul
Chulalongkorn University Theses and Dissertations (Chula ETD)
This study applies reinforcement learning to credit scoring by using the logistic bandit framework. The credit scoring and the credit underwriting are modeled into a single sequential decision problem where the credit underwriter takes a sequence of actions over an indefinite number of time steps. The traditional credit scoring approach considers the model construction separately from the underwriting process. This approach is identified as a greedy algorithm in the reinforcement learning literature, which is commonly believed to be inferior to an efficient reinforcement learning approach such as Thompson sampling. This is true under the simple setting, i.e., granting credit to …

Spatio-Temporal Copula-Based Graph Neural Networks For Traffic Forecasting, Pitikorn Khlaisamniang
Chulalongkorn University Theses and Dissertations (Chula ETD)
Modern cities heavily rely on complex transportation, making accurate traffic speed prediction crucial for traffic management authorities. Classical methods, including statistical techniques and traditional machine learning techniques, fail to capture complex relationships, while deep learning approaches may have weaknesses such as error accumulation, difficulty in handling long sequences, and overlooking spatial correlations. Graph neural networks (GNNs) have shown promise in extracting spatial features from non-Euclidean graph structures, but they usually initialize the adjacency matrix based on distance and may fail to detect hidden statistical correlations. The choice of correlation measure can have a significant impact on the resulting adjacency matrix …
