While such a system is innovative, and has solidified its prevalence to the public, it is still in its infancy with many improvements yet to come. One of the largest issues present is the imbalance of the Bike Sharing System (BSS), or more broadly ridesharing systems, the unavailability of bikes or empty parking spaces in areas with a high density of users. In this paper, we propose a spatial crowdsourcing approach where users receive monetary incentives to rebalance bikes by returning bikes to stations that need it rather than users' intended locations to improve the system's overall bike utilization. However, how to determine the best incentive mechanism is challenging. We formulate this problem into an optimal matching problem and convert it into a minimum-cost flow problem to find the best way to choose which stations to rebalance and the optimal rebalancing amount. To demonstrate the effectiveness of the proposed method, we validate our approach using D.C. Capital BikeShare data and extensive simulation shows that our approach on average can improve the efficiency and cost of simple greedy algorithms by 32.1%.","PeriodicalId":175851,"journal":{"name":"2021 International Conference on Cyber-Physical Social Intelligence (ICCSI)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126665471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although deep learning-based approaches, such as Convolutional Neural Networks (CNN), have been shown to be effective for feature representation, thereby achieving good performance in vein verification tasks, they typically are trained on large labeled datasets. In general, labeling vein images is expensive and time cost, and typical hand-tuned approaches for data augmentation can not collect the complex variations in such images. To address this problem, a novel unsupervised domain adaptation approach, named CycleGAN-based domain adaptation (CGAN-DA), is proposed to automatically extract discriminant from the palm-vein network, without the need of any image annotation. Our proposed CGAN-DA allows a learning scheme that ensures a synergistic fusion of adaptations image-wise and feature-wise. Concretely, we transform the image appearance across two domains (palm-vein image domain and retinal image domain), in order to enhance the domain-invariance of the extracted features for the palm-vein segmentation task. Without using any annotation from the target domain (palm-vein images), our model learning is guided by several adversarial losses, a cycle consistence loss and a segmentation loss. Our experimental on the public CASIA palm-vein dataset show that our approach is capable of achieving state-of-the art verification accuracy.","PeriodicalId":175851,"journal":{"name":"2021 International Conference on Cyber-Physical Social Intelligence (ICCSI)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116810219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is minimal research concerning PI patient mortality prediction. There is a need for more accurate prediction modeling for ICU patients diagnosed with PI. This paper demonstrates performance improvements in predicting the mortality of ICU patients diagnosed with PI after 24 hours of being admitted. The proposed framework, PMPI(Process Mining Model to predict mortality of PI patients), is a modification of the work used for prediction of in-hospital mortality for ICU patients with diabetes. PMPI demonstrates similar if not better performance with an Area under the ROC Curve (AUC) score of 0.82 compared to the best results of the existing literature. PMPI uses patient medical history, the time related to the events, and demographic information for prediction. The PMPI prediction framework has the potential to help medical teams in making better decisions for treatment and care for ICU patients with PI to increase their life expectancy.","PeriodicalId":175851,"journal":{"name":"2021 International Conference on Cyber-Physical Social Intelligence (ICCSI)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115735748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The approach uses a masking layer which is initialized based on the reachability graph of the process model. Additionally, modifications to the neural network architecture are proposed to increase the predictive performance.
