Special Issue Information

Dear Colleagues,

Today, data science and machine learning remain pivotal pillars for solving the most intricate real-world challenges. Their versatility and utility span across various domains, including medicine, finance, text mining, image analysis, and more. Simultaneously, the abundance of user-accessible data continues to escalate, with concepts like big data and data streams garnering ever-increasing recognition. However, traditional classification methods may exhibit questionable efficacy in handling such data complexities, thereby necessitating continuous advancements in machine learning methodologies.

The second edition of this special session centers on the intricacies of real-world data and the impact of entropy on machine learning algorithms. Our particular focus lies on novel classification algorithms that harness the power of data science to model and process diverse real-world datasets effectively.

We welcome researchers to submit their original work, showcasing innovative approaches to data classification and analysis of real-world datasets, with a keen emphasis on entropy and its influence on machine learning effectiveness. We aim to foster a collaborative platform for exchanging knowledge and experiences related to cutting-edge developments in data science and data classification.

Computer vision in sports analytics is gaining in popularity. Monitoring players’ performance using cameras is more flexible and does not interfere with player equipment compared to systems using sensors. This provides a wide set of opportunities for computer vision systems that help coaches, reporters, and audiences. This paper provides an introduction to the problem of measuring boxers’ performance, with a comprehensive survey of approaches in current science. The main goal of the paper is to provide a system to automatically detect punches in Olympic boxing using a single static camera. The authors use Euclidean distance to measure the distance between boxers and convolutional neural networks to classify footage frames. In order to improve classification performance, we provide and test three approaches to manipulating the images prior to fitting the classifier. The proposed solution achieves 95% balanced accuracy, 49% F1 score for frames with punches, and 97% for frames without punches. Finally, we present a working system for analyses of a boxing scene that marks boxers and labelled frames with detected clashes and punches. Full article

In a standard binary supervised classification task, the existence of both negative and positive samples in the training dataset are required to construct a classification model. However, this condition is not met in certain applications where only one class of samples is obtainable. To overcome this problem, a different classification method, which learns from positive and unlabeled (PU) data, must be incorporated. In this study, a novel method is presented: neighborhood-based positive unlabeled learning using decision tree (NPULUD). First, NPULUD uses the nearest neighborhood approach for the PU strategy and then employs a decision tree algorithm for the classification task by utilizing the entropy measure. Entropy played a pivotal role in assessing the level of uncertainty in the training dataset, as a decision tree was developed with the purpose of classification. Through experiments, we validated our method over 24 real-world datasets. The proposed method attained an average accuracy of 87.24%, while the traditional supervised learning approach obtained an average accuracy of 83.99% on the datasets. Additionally, it is also demonstrated that our method obtained a statistically notable enhancement (7.74%), with respect to state-of-the-art peers, on average. Full article
