Automated sports commentary is a form of automated narrative. Sports commentary exists to keep the viewer informed and entertained. One way to entertain the viewer is by telling brief stories relevant to the game in progress. We present a system called the sports commentary recommendation system (SCoReS) that can automatically suggest stories for commentators to tell during games. Through several user studies, we compared commentary using SCoReS to three other types of commentary and show that SCoReS adds significantly to the broadcast across several enjoyment metrics. We also collected interview data from professional sports commentators who positively evaluated a demonstration of the system. We conclude that SCoReS can be a useful broadcast tool, effective at selecting stories that add to the enjoyment and watchability of sports. SCoReS is a step toward automating sports commentary and, thus, automating narrative.
The purpose of this study is to analyze the structural patterns of international student inflow and predict future trends using the ARIMA model. By employing data from 2010 to 2023 on international students in South Korea, the study ensures stationarity through differencing and identifies the optimal ARIMA(2, 1, 1) configuration via ACF and PACF analyses. Results highlight the significant impact of external shocks, such as the COVID-19 pandemic, on student enrollment trends, followed by a gradual recovery. The study also identifies key factors influencing student attraction and retention, including nationality, gender, degree type, language proficiency, and educational satisfaction. Moreover, the research incorporates multivariate analysis, offering insights into the role of tailored support programs such as language education, cultural adaptation services, and academic assistance. These findings provide practical recommendations for enhancing recruitment strategies and underline South Korea's potential to strengthen its position as a global educational hub through data-driven policymaking and strategic planning..
Abstract Background Early diagnosis of structural heart disease improves patient outcomes, yet many remain underdiagnosed. While population screening with echocardiography is impractical, electrocardiogram (ECG)-based prediction models can help target high-risk patients. We developed a novel ECG-based machine learning approach to predict multiple structural heart conditions, hypothesizing that a composite model would yield higher prevalence and positive predictive values (PPVs) to facilitate meaningful recommendations for echocardiography. Methods Using 2,232,130 ECGs linked to electronic health records and echocardiography reports from 484,765 adults between 1984-2021, we trained machine learning models to predict the presence of any of seven echocardiography-confirmed diseases within one year. This composite label included: moderate or severe valvular disease (aortic/mitral stenosis or regurgitation, tricuspid regurgitation), reduced ejection fraction <50%, or interventricular septal thickness >15mm. We tested various combinations of input features (demographics, labs, structured ECG data, ECG traces) and evaluated model performance using 5-fold cross-validation, multi-site validation trained on one clinical site and tested on 11 other independent sites, and simulated retrospective deployment trained on pre-2010 data and deployed in 2010. Findings Our composite “rECHOmmend” model using age, sex and ECG traces had an area under the receiver operating characteristic curve (AUROC) of 0.91 and a PPV of 42% at 90% sensitivity at a prevalence of 17.9% for our composite label. Individual disease models had AUROCs ranging from 0.86-0.93 and lower PPVs from 1%-31%. The AUROC for models using different input features ranged from 0.80-0.93, increasing with additional features. Multi-site validation showed similar results to the cross-validation, with an aggregate AUROC of 0.91 across our independent test set of 11 clinical sites after training on a separate site. Our simulated retrospective deployment showed that for ECGs acquired in patients without pre-existing known structural heart disease in a single year, 2010, 11% were classified as high-risk, of which 41% developed true, echocardiography-confirmed disease within one year. Interpretation An ECG-based machine learning model using a composite endpoint can predict previously undiagnosed, clinically significant structural heart disease while outperforming single disease models and improving practical utility with higher PPVs. This approach can facilitate targeted screening with echocardiography to improve under-diagnosis of structural heart disease.
Introduction: A deep learning ECG algorithm, rECHOmmend, can accurately identify patients with any of seven structural heart diseases: five valvular diseases, low ejection fraction and interventricular septal (IVS) thickening. Components of the rECHOmmend composite label (IVS>15mm, mitral regurgitation) are also associated with hypertrophic cardiomyopathy (HCM). We hypothesized that despite being trained without HCM-specific labels, rECHOmmend can reliably identify HCM patients and achieve comparable performance to an HCM-specific classifier. Methods: Algorithms were developed from 2,898,979 ECGs acquired from 661,366 patients between 1984-2021. rECHOmmend was trained on a composite label derived from echocardiography and electronic health record (EHR) data. This ensemble model consists of 7 disease specific models with an aggregate model to predict a composite structural heart disease endpoint with shared clinical actionability. Separately, an HCM-specific model was trained on a binary label derived from EHR. To enable comparison, both classifiers were tested on a shared ECG holdout set (ECG prevalence 1.24%, patient prevalence 0.52%). Results: Despite being trained without HCM specific labels, the rECHOmmend ensemble showed comparable performance to a HCM-specific classifier (C-statistic: 0.92 [0.90-0.93] vs 0.90 [0.89-0.91]). At an operating point optimized for the F1-score, the sensitivity to HCM was higher for rECHOmmend at 0.42 [0.33-0.50] compared to 0.18 [0.15-0.21] for the HCM-specific classifier. rECHOmmend sustained performance across a range of IVS thicknesses, suggesting it was not solely reliant on IVS thickening for HCM identification and other ensemble components contributed to performance. Conclusions: A composite deep learning algorithm trained to identify structural heart diseases can identify clinically ascertained HCM with good performance, despite being trained without HCM-specific labels.
Automated image interpretation is an important task in numerous applications ranging from security systems to natural resource inventorization based on remote-sensing. Recently, a second generation of adaptive machine-learned image interpretation systems have shown expert-level performance in several challenging domains. While demonstrating an unprecedented improvement over hand-engineered and first generation machine-learned systems in terms of cross-domain portability, design-cycle time, and robustness, such systems are still severely limited. This paper reviews the anatomy of the state-of-theart Multi resolution Adaptive Object Recognition framework (MR ADORE) and presents extensions that aim at removing the last vestiges of human intervention still present in the original design of ADORE. More specifically, feature selection is still a task performed by human domain experts thereby prohibiting automatic creation of image interpretation systems. This paper focuses on autonomous feature extraction methods aimed at removing the need for human expertise in the feature selection process.
The surveying industry is a rising at a rapid rate through advancements in technology. Other specific industries such as industrial metrology which were once segregated from surveying are now closely aligned through the form of measurement. The oil and gas industry provides an avenue for both to co-exist given the specifications and tolerances required to undertake highly accurate surveys. Flange surveys require a specialised form of measurement given the intent of the survey is predominantly for design and reverse engineering applications. Current techniques are not familiar in the surveying industry nor the accuracies that can be achieved.
In this study, a Leica AT402 laser tracker is used as a baseline reading to survey two existing flanges and a spool fabrication joining them. Two conventional survey methods will then be surveyed with the results then analysed and compared. The two conventional survey methods will be based on a Leica TS15 total station and a Leica HDS7000 laser scanner. The results will be based on three main components for calculation – Flange centreline coordinates, plane inclination and bolt hole rotation.
The datasets found that the total station performed better than expected with accurate and consistent results compared to the laser scanner readings and ultimately the baseline readings of the laser tracker. The flange centreline coordinate errors for the total station were submillimetre reading 0.69mm and 0.75mm respectively. The plane inclination and bolt hole rotation results were also similar if not more accurate. The laser scanner results varied between 1mm and 3mm with inconsistent results achieved due to a couple of factors mainly contributed to the manipulation of the point cloud when cleaning and trimming. The laser scanner results provide room for further research to investigate more advanced techniques when working with point clouds.
