Abstract

Ensuring water potability is paramount for public health and safety. This research aimed to assess the efficacy of the Decision Tree classification algorithm in predicting water potability using the Water Quality and Potability dataset. Employing a 5-fold cross-validation technique, the model showcased a moderate performance with an average accuracy of approximately 54.33%. While the Decision Tree provides a baseline and interpretable mechanism for classification, the results emphasize the need for further exploration using more intricate models or ensemble methods. This study contributes to the broader effort of leveraging machine learning techniques for water quality assessment and provides insights into the potential and limitations of such models in predicting water safety

Abstract

This study, titled "Evaluating Thresholding-Based Segmentation and HuMoment Feature Extraction in Acute Lymphoblastic Leukemia Classification using Gaussian Naive Bayes," investigates the application of image processing and machine learning techniques in the classification of Acute Lymphoblastic Leukemia (ALL). Utilizing a dataset of microscopic blood smear images, the research focuses on the efficacy of thresholding-based segmentation and Hu moment feature extraction in distinguishing between benign and malignant cases of ALL. Gaussian Naive Bayes, known for its simplicity and effectiveness, is employed as the classification algorithm. The study adopts a 5-fold cross-validation approach to evaluate the model's performance, with particular emphasis on metrics such as accuracy, precision, recall, and F1-score. Results indicate a high precision rate across all folds, averaging approximately 84.13%, while exhibiting variability in accuracy, recall, and F1-scores. These findings suggest that while the model is effective in identifying malignant cases, further refinements are necessary for improving overall accuracy and consistency. This research contributes to the field of medical image analysis by demonstrating the potential of combining simple yet efficient techniques for the automated diagnosis of hepatological diseases. It highlights the importance of integrating image processing with machine learning to enhance diagnostic accuracy in medical applications.

Abstract

This study investigates the use of the K-Nearest Neighbors (KNN) algorithm for the binary classification of mushroom edibility using a cleaned version of the UCI Mushroom Dataset. The dataset underwent pre-processing techniques such as modal imputation, one-hot encoding, z-score normalization, and feature selection to ensure data quality. The model was trained on 80% of the dataset and evaluated on the remaining 20%, achieving an overall accuracy of 99%. Evaluation metrics, including precision, recall, and F1-score, confirmed the model's effectiveness in distinguishing between edible and poisonous mushrooms, with minimal misclassification errors. Despite its high performance, the study identified scalability as a limitation due to the computational complexity of KNN, suggesting that future research should explore alternative algorithms for enhanced efficiency. This research underscores the importance of pre-processing and hyperparameter optimization in building reliable classification models for food safety applications.

Abstract

Penelitian ini mengkaji penerapan teknik Word Clouds dalam ekstraksi sentimen pada platform Twitter, dengan fokus pada identifikasi kata dominan dalam cuitan yang dikategorikan sebagai netral, positif, dan negatif. Teknik visualisasi ini memungkinkan pemahaman yang lebih mendalam mengenai distribusi kata dan peranannya dalam representasi sentimen. Melalui Exploratory Data Analysis (EDA), penelitian ini berhasil memetakan karakteristik data, seperti tingginya kemiripan Jaccard untuk tweet netral dan pola distribusi panjang teks antara text dan selected_text. EDA juga mendasari penerapan aturan deterministik (rule-based gate) untuk menangani cuitan dengan kepastian tinggi dan membedakan kasus yang membutuhkan pendekatan berbasis model lebih lanjut, yaitu Named Entity Recognition (NER). Penerapan rekayasa fitur meta, termasuk pengukuran similarity Jaccard, selisih panjang kata, dan jumlah kata, berhasil meningkatkan presisi dalam pemetaan span sentimen pada teks mikro. Evaluasi model menggunakan similarity Jaccard menunjukkan performa yang sangat baik dengan akurasi 85%, diikuti oleh konsentrasi tinggi skor prediksi pada rentang 0,9–1,0. Temuan ini menegaskan bahwa pendekatan hibrida yang mengintegrasikan Word Clouds, analitik berbasis fitur, dan NER efektif dalam mengatasi tantangan kompleksitas bahasa informal di media sosial, seperti slang, elongation, dan ambiguity. Penelitian ini memberikan kontribusi signifikan dalam pengembangan metodologi sentiment extraction yang lebih presisi dan efisien untuk aplikasi Natural Language Processing (NLP) di platform sosial media
