The unprecedented availability of new types of data coupled with the invention of new technologies combine to enable entirely new or higher-resolution services that in turn enable more rational and data-driven processes. We consider the overall process of vehicular transportation and, more specifically, the process of deciding which route to follow when having to reach a destination. Early solutions modeled a road work as a graph, used sparse in-road sensor data to assign weights to graph edges, and then applied improved versions of Dijkstra's algorithm to find routes with the lowest sums of edge weights. Since then, massive vehicle trajectory data has become available. When coupled with new technologies, this data enables entirely new and higher-resolution routing services that in turn enable better routing. For more than a decade, the authors have engaged in research aimed at exploiting trajectory data to enable better routing. The resulting technologies were developed outside a DBMS. Here, we cover aspects of this research. Further, we challenge the community to develop DBMS support for these and other aspects of routing. © 2024 IEEE.

The pervasiveness of social media has facilitated unprecedented communication and expression, but also fueled a surge in defamation cases. In Thailand, defamation carries significant legal weight, posing challenges for identifying and prosecuting perpetrators due to online anonymity and rapid content dissemination. This research proposed a novel machine learning approach to detect defamatory words in Thai social media comments. We utilized the state-of-the-art BERT model and the PyThaiNLP library, alongside a unique dataset of labeled comments from the Criminal Court of Thailand. This robust framework aimed to effectively identify potentially defamatory content, contributing to a safer and more responsible online environment. © 2024 IEEE.

In the dynamic landscape of higher education, there is a growing need to comprehend and address student stress. This demand has led to the development of a comprehensive Computational Analysis Framework for University Student Stress. The framework aims to develop the field by introducing innovative tools and systems for data collection, preparation, exploratory data analysis, principal component analysis, and clustering. Unlike existing methodologies, our approach pioneers a systematic and technologically advanced solution to analyze stress levels and coping strategies among university students. © 2024 IEEE.

Machine learning (ML) models have been used in functional neuroimaging for wide-ranging tasks, ranging from disease diagnosis to disease prognosis. There have been successive functional connectivity-based ML studies focused on improving model performances for disease detection. An increasing number of such studies use their trained models to detect and evaluate salient features that could be potential biomarkers of these neuro-logical conditions. The evaluation of these salient features is often qualitative and limited to cross-referencing existing literature for similar findings. In this study, we present objective quantitative metrics to evaluate the robustness of these salient features. Building upon existing generic evaluation metrics, we propose metrics that capture topological properties known to be characteristic of brain functional connectomes. Using existing and newly proposed measures on a set of baselines and state-of-the-art graph neural networks (GNN) models, we found that when GNNExplainer is used with models that incorporate attention, the scores produced are relatively more robust than other combinations. On datasets of patients with Autism Spectrum Disorder (ASD) or Attention-deficit Hyperactivity Disorder (ADHD), our proposed metrics highlighted that salient features identified in both disorders are highly involved in functional specialization, while salient ASD features expressed stronger functional integration than ADHD. We package these existing and novel metrics together in the RE-CONFIRM framework that holds promise to set the foundations for the quantitative evaluation of salient features detected by future studies. © 2024 IEEE.

Crop pests can significantly impact productivity, making early detection and prevention crucial for management. Machine learning approaches are being used to forecast crop diseases using a variety of data sets. Relatively easy access to the environment data has resulted in a lot of attempts at predicting diseases and pests using this data. In this research, we provide a model that uses deep learning technique known as Simplified YOLO 3.1 architecture to examine past crop growth environment data to forecast illnesses. Utilizing large public datasets on crops such as tomato, pepper, grape, strawberry, and paprika, we show that the model is capable of accurately forecasting crop pest and disease risk. With an average accuracy of 98% and precision of 96%, it showed excellent predictive power. The anticipated results can help with post-harvest processing or insect control. It is expected that this learning framework and crop disease prediction model, which is based on environmental data, will be extensively useful for the prevention of pests and diseases in various facilities and crops. © 2025 IEEE.

Accurate and efficient land-use classification is important for the formulation of plans by urban planners, environmental monitoring, and even sustainable development. The paper explores the use of transfer learning methods that utilize pre-trained models to improve LSTM and DNNs' performance when applied on metropolitan settings for LAC. This can be done using transfer learning to learn from large datasets and adapt to the complexities of urban land-use patterns even with limited labeled data. This study uses the UC-Merced-LandUse dataset and heatmap analysis to visualize the models' classification decisions in demonstrating the effectiveness of this approach. This research contributes to the advancement of land-use classification techniques, which enable more accurate and informed urban planning and environmental management. © 2025 IEEE.

Consider the domain of multiclass classification within the adversarial online setting. What is the price of relying on bandit feedback as opposed to full information? To what extent can an adaptive adversary amplify the loss compared to an oblivious one? To what extent can a randomized learner reduce the loss compared to a deterministic one? We study these questions in the mistake bound model and provide nearly tight answers. We demonstrate that the optimal mistake bound under bandit feedback is at most O(k) times higher than the optimal mistake bound in the full information case, where k represents the number of labels. This bound is tight and provides an answer to an open question previously posed and studied by Daniely and Helbertal ['13] and by Long ['17,'20], who focused on deterministic learners. Moreover, we present nearly optimal bounds of Θ˜(k) on the gap between randomized and deterministic learners, as well as between adaptive and oblivious adversaries in the bandit feedback setting. This stands in contrast to the full information scenario, where adaptive and oblivious adversaries are equivalent, and the gap in mistake bounds between randomized and deterministic learners is a constant multiplicative factor of 2. In addition, our results imply that in some cases the optimal randomized mistake bound is approximately the square-root of its deterministic parallel. Previous results show that this is essentially the smallest it can get. Some of our results are proved via a reduction to prediction with expert advice under bandit feedback, a problem interesting on its own right. For this problem, we provide a randomized algorithm which is nearly optimal in some scenarios. © 2024 Neural information processing systems foundation. All rights reserved.

Today more people use social media to express their opinion and their emotions. There are many types of text in social media including text that convey a tendency to be depressed or suicidal. We use sentiment analysis to detect suicidal texts, because if detected, it could save many lives and many families. In this research, we have an objective to explore a method that is both high performance and less time-using. We design experiments that have 30 combinations between five machine learning models with six feature engineering methods. All experiments use accuracy and total time for model generation as metrics. We use deep neural networks with glove embedding as a comparator because this combination performed well in this dataset on Kaggle competition. From the experimental results, we find that the suitable combination that generates fast and has good accuracy is Random Forest with TF-IDF with 0.897 and 145 seconds. © 2023 IEEE.
