The evolution of social networks has resulted in medium to express feelings and thoughts of an individual to global audience, thanks to the rapid expansion of the Internet. Many individual utilize textual content, images, audio, and videos to convey their emotions and perspectives. However, the sheer volume of text-based communication on social media can be overwhelming. Each second, an enormous quantity of unstructured information is created online through these platforms. To comprehend human psychology in real-time, this data needs to be processed promptly, and one way to achieve this is through sentiment analysis. Sentiment analysis identifies the polarity of texts, determining whether the author holds a opinion of a negative, favourable, or neutral nature product, service, person, or location. In certain applications, sentiment analysis alone may be insufficient, necessitating the inclusion of emotion detection to accurately determine condition of one's mind or heart. Sentiment analysis and emotion detection from textual data are both covered in depth in this work, with explicitly revealed insights into the distinct stages of sentiment analysis and the corresponding emotion models. © 2023 IEEE.

This project focuses on developing a deep learning algorithm to classify eye diseases from images. The dataset comprises images depicting various eye conditions, including glaucoma, cataracts, normal eyes, and diabetic retinopathy. We adopt a comprehensive approach by utilizing pre-trained architectures such as ResNet-18, GoogleNet, AlexNet, VGG19, and ResNet-50 as the backbone of our models, fine-tuning each on our dataset. During the training process, we employed data augmentation techniques to enhance the dataset, improving the models' generalization ability across diverse eye conditions. The evaluation of the models involves a combination of cross-entropy loss and accuracy metrics to assess performance. Notably, the individually trained models exhibited varying accuracies, with ResNet-18 achieving the highest accuracy of 92.7% on the validation set. Additionally, we conducted an analysis of model performance using metrics such as precision, recall, and F1-score, further enhancing our understanding of the models' capabilities. The visualization of results is facilitated through the presentation of confusion matrices, providing insights into the models' classification behavior across different eye diseases. This study opens up a promising new path for improving ophthalmology screening and diagnosis by demonstrating the prospective benefits of deep learning in automating the classification of eye diseases. © 2024 IEEE.

Next-generation intelligent transportation systems aim to achieve many cooperative perception and cooperative driving functions that require considerable computational resources. Offloading such tasks via mobile edge computing is considered part of the solution;this approach is currently being studied within the scope of 5G networks and beyond. In the automotive context, such edge systems could be roadside units (RSUs), which can easily be overloaded at peak times. Vehicular microcloud approaches have been proposed to overcome such problems by sharing the computational resources of nearby cars. In this study, we propose an offloading system architecture to enable such offloading in a vehicular microcloud interconnected by a 5G core network. We model the system as a queueing model to derive closed-form solutions for selected performance metrics. Based on our insights, we propose the triple-check offloading algorithm (TCOA) to obtain both the best offloading ratio of the vehicular microcloud to the entire offloading system and the optimal maximum number of the remaining vehicle instances in the vehicular microcloud. Our simulation results show that the proposed TCOA achieves better system performance than four other offloading schemes in terms of cost, response time, service rate, and cost response-time production service rate division (CRPSD). © 2013 IEEE.

The recent emergence of Large Language Model (LLM)-based tools such as OpenAI's ChatGPT and Google's Gemini has sparked excitement across the software development industry, and offered promises to transform the software development process. Despite the enthusiasm, it remains uncertain whether these tools are already good enough at coding to replace the role of software developers. Currently, no studies have provided insights into the performance of LLMs, such as understanding which characteristics of a programming task might affect an LLM's performance, or predicting how an LLM will handle new programming challenges. In this work, we address these challenges by first creating a data collection framework to gather 3,323 programming tasks from Kattis, a widely-used programming challenge platform. We then use OpenAI's ChatGPT to solve these programming tasks. The solutions obtained from ChatGPT are submitted back to Kattis to evaluate their correctness and effectiveness. Next, we use the collected data, including both problem and solution information, to analyze the task characteristics that significantly influence ChatGPT's performance. Building on the analysis, we develop predictive models that can forecast the efficacy of ChatGPT on new programming problems. Our analysis indicates that factors such as the difficulty level of a programming challenge, or the readability complexity of a problem description can significantly affect the efficacy of ChatGPT. Finally, the experimental results show that our predictive model can correctly predict ChatGPT performance with an accuracy of up to 90% for easy problems, and up to 79% for difficult problems. © 2024 IEEE.

Micro-expressions are spontaneous, rapid and subtle facial movements that can hardly be suppressed or fabricated. Micro-expression recognition (MER) is one of the most challenging topics in affective computing. It aims to recognize subtle facial movements which are quite difficult for humans to perceive in a fleeting period. Recently, many deep learning-based MER methods have been developed. However, how to effectively capture subtle temporal variations for robust MER still perplexes us. We propose a counterfactual discriminative micro-expression recognition (CoDER) method to effectively learn the slight temporal variations for video-based MER. To explicitly capture the causality from temporal dynamics hidden in the micro-expression (ME) sequence, we propose ME counterfactual reasoning by comparing the effects of the facts w.r.t. original ME sequences and the counterfactuals w.r.t. counterfactually-revised ME sequences, and then perform causality-aware prediction to encourage the model to learn those latent ME temporal cues. Extensive experiments on four widely-used ME databases demonstrate the effectiveness of CoDER, which results in comparable and superior MER performance compared with that of the state-of-the-art methods. The visualization results show that CoDER successfully perceives the meaningful temporal variations in sequential faces. © The Author(s) 2024.
