    A Hybrid Approach to Bangla Regional Text Classification Using BERT Ensemble and Region-Specific Lexical Oversampling

    No full text
    pdfRegional text analysis reflects the lived realities of diverse communities by capturing the linguistic richness and diversity present in various dialects. It bridges the gap between everyday regional usage and standardized language forms, thereby enhancing the inclusivity of language technologies. In this paper, we focus on five regional dialects in Bangladesh, namely Chittagong, Sylhet, Noakhali, Barishal, and Rangpur, using a dataset of 4,218 text samples. The dataset is validated by five regional experts and categorized into three tiers based on an assigned agreement criterion. Tier 1 represents a strictly filtered, high-confidence subset and is used primarily for evaluation. A set of region-specific special words, which belong exclusively to their respective regions and are validated by domain experts, is introduced. These words are used in a linguistically informed oversampling technique to balance the dataset in both experiments. In the first experiment, we demonstrate the effectiveness of the tiered dataset structure, where Tier 2 and Tier 3 (mediumand low-confidence subsets) are used for training, and Tier 1 (high-quality subset) is used for testing. In this setting, BanglaBERT achieves the best individual performance with 67.45% accuracy and a weighted F1-score of 67.62%. In the second experiment, we focus exclusively on the Tier 1 dataset, applying a wide range of machine learning and deep learning models to assess their effectiveness. The key contribution is a heterogeneous deep ensemble technique that combines three BERT models, BanglaBERT, BUETBERT, and DistilBERT, achieving an accuracy of 85.17% and a weighted F1-score of 84.84% on the Tier 1 dataset. iiiCSE UI

    An Explainable Ensemble Convolutional Neural Network for Early Lung Cancer Prediction with Web Application

    No full text
    CSE UIULung Cancer is one of the deadliest forms of cancer significantly contributing to the rising mortality rates globally. The high mortality rate associated with lung cancer can largely be attributed to its late detection, as symptoms often do not appear until the disease has reached advanced stages. Early detection of anomalies in medical imaging, particularly at the initial stages, is crucial for advancing both quantitative image analysis and patient care. In this context, our research introduces a fully automated web application to predict lung cancer early on CT scan images. This application leverages the power of a weighted average ensemble-based deep learning framework that combines multiple neural network architectures to enhance the reliability of automated classification. The work highlights the need for interpretability in clinical decision support systems, going beyond classification. Our proposed approach is organized into three independent phases. First, we performed image augmentation as part of the preprocessing stage analyzing the IQ-OTH lung cancer dataset which implies that the model is trained on diverse and enriched input data. The system incorporates ResNet50, VGG16, and a custom CNN, all of which provide complementary feature-learning capabilities that improve overall predictive dependability. The ensemble model clearly outperformed the individual networks, achieving an accuracy of 92.28% on the IQ-OTH lung cancer dataset. The visual indications and regions that most influence our model’s decisions are highlighted using Explainable Artificial Intelligence techniques, particularly LIME and SHAP. By making the model’s inner workings more understandable, these explanations hope to boost medical practitioners’ confidence. Finally, the ensemble model was integrated into a user-friendly web application allowing users to upload CT scan images, which are then analyzed to classify the images into normal, benign, or malignant categories. Furthermore, our web application gives confidence levels for each prediction increasing the credibility of its results. Our system provides medical practitioners with a smooth and effective tool by integrating the precision of an ensemble model with the flexibility of a web application.CSE UI

    Recognition of Bangla and English Words in Bangla Texts Using a Modified BERT-base-NER Model

    No full text
    CSE UIUA combination of Bangla and English words is commonly used, particularly on social media. This tendency greatly hampers the next generation’s ability to learn Bangla. This study suggests an approach for identifying words in Bangla texts that are both English and Bangla. This study also translates the identified English terms into standard Bangla words. The Transformer architecture, which uses an attention mechanism to identify the connections between words and their contexts inside a text, is the foundation of bidirectional encoder representations from transformers (BERT). In this study, we use the training input dataset to modify the BERT-base-NER model. For the name entity recognition (NER) task, the proposed BERT-base-NER model in this study achieves state-of-the-art performance. For both the training and testing scenarios, we employ a holdout cross-validation procedure. We used 80% of the entire data for training and 20% for testing. We use the Google Translate API (application programming interface) to translate the identified English words into standard Bangla words. In order to assess the modified BERT-base-NER model, we applied the input dataset to the current machine learning (ML) and deep learning (DL) techniques. Support vector machines (SVM) and Naive Bayes (NB) are two components of the machine learning approach. Conversely, the DL method uses bidirectional LSTM (BiLSTM), long short-term memory (LSTM), and convolutional neural network (CNN). The improved BERT-base-NER model is highly accurate and efficient at identifying Bangla and English words, according to simulation data. With an accuracy of 95%, the proposed BERT-base-NER model achieves the best result among the current methods. For Bangla–English code-mixed text, this study presents a reliable BERT-based word-level language identification system that successfully resolves Banglish ambiguity and allows downstream Bangla language processing applications such as standard Bangla conversion, machine translation, and information extraction.CSE UI

    During my last trimester at United International University for my "Bachelor of Business Administration," I completed a four-month internship with Quantanite Bangladesh. Quantanite Bangladesh is one of the country's leading BPO facilities. Business process outsourcing (BPO), on the other hand, is the practice of a corporation assigning all of its internal tasks to another organization. Business process outsourcing begins when an organization believes it can profit by contracting with an outside firm to manage a business function, including supply chain management, marketing, accounting, or management information systems. In order to ensure client satisfaction, this study aims to investigate the quality of BPO services and how Quantanite Bangladesh Limited manages and maintains them for its contractual services. The report is structured as follows: Introduction, BPO industry overview, Company Overview, MIS in HR and how it is helping to cut cost and make the process efficient. Lastly How MIS process helps the IT department. At Quantanite Bangladesh Limited, financial details were maintained through work experience. Lastly, the information acquired from working with Quantanite Bangladesh Limited is used to provide proposals for enhancing the field. I became well acquainted with the company during my four-month internship and learned about their role and importance. I learned a lot about various apps and received a lot of training relating to my job. Working with these friendly coworkers and skilled lecturers also helped me get better at Excel. I had the chance to participate greatly and carry out live job. As an intern, I can attest that the entire journey was both alluring and challenging. I had the chance to test myself in every manner during the course of these four months. I can thus say with confidence that one of the best choices I've ever made was to collaborate with Quantanite Bangladesh
