These voyages require enormous planning and data collection processes. Existing mariner data is available in disparate locations and lacks predictive or forecasting information. This makes a mariner’s voyage planning processes manual, ad-hoc, and present-minded. RippleGo utilizes two AI-based predictive technologies. The first technology is a deep learning based algorithm to forecast river levels. Advanced knowledge of river levels help in planning cargo loads and safely navigating under bridges and through locks. The second AI technology is a machine learning based technology that predicts time taken to travel from one point to any other point along the waterways. Advanced information on travel time will enable mariners to provide accurate ETAs to customers and port terminals and improve supply chain reliability. RippleGo combines the two methodologies to provide efficient voyage plans with better situational awareness, safety alerts (through Bridge Air Gap (BAG) and Under Keel Clearances (UKC)), improved reliability of delivery, and better utilization of water transportation ports and terminals.","PeriodicalId":129324,"journal":{"name":"2023 IEEE Conference on Artificial Intelligence (CAI)","volume":"21 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120857239","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 methodology for scheduling is modeled as a reinforcement learning (RL) agent that resolves potential conflicts for the traffic and balances the demand and capacity at vertiports. The reason behind to use RL is that specific problem requires a very quick response since it also deals with resolving conflicts that are observed between the flights that are about to take-off and the contingent flights that diverted for an emergency landing. The main objective of this work is to develop a pre-flight planning service to work compatible with contingency management activities for enhancing the contingency management process for the AAM system.","PeriodicalId":129324,"journal":{"name":"2023 IEEE Conference on Artificial Intelligence (CAI)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131393854","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 import of artificial neural networks into train delay prediction helps to improve prediction accuracy. In this paper, we propose a novel stacking ensemble regression model (ST-NN) that uses MultiLayer Perceptron’s (MLP) neural networks as single learners and MLP as the meta-learner, which enhances the accuracy of Passenger Train arrival delay prediction time in minutes. We evaluated the model performance using Amtrak data to compare with other combinations of stacking ensembles and single learners including, Decision Trees (DT), Random Forest (RF), Gradient Boosting Machines (GBM), XGBoost (XGB), LightGBM (LGBM), regression algorithms, Artificial Neural Network (ANN), and MLP to determine enhanced model accuracy of our model. The experiments demonstrate that our ST-NN regression model significantly improves model evaluation indicators by producing a 63.4-82.37% decrease in Mean Absolute Error. Furthermore, the accuracy outperforms the best benchmark models regarding train delay prediction.","PeriodicalId":129324,"journal":{"name":"2023 IEEE Conference on Artificial Intelligence (CAI)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131959886","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}

That regards systems that apply data in machine learning for tasks like medical diagnostics. Especially deep learning algorithms perform better by using a large amount of data and are now able to benefit from the large amount as well with limited training time given access to high-performance computing resources. This paper address and discuss the tradeoffs like the one we have between data sharing minimalization for increased privacy and data maximization for machine learning systems.

Various image and point cloud based object detection methods have been proposed. Image based detectors are sensitive to illumination changes and cannot get accurate 3D information. Point cloud based detectors are less convenient for acceleration and deployment on commonly used hardware due to the unstructured nature of point cloud data, making it prohibitive for mobile platforms with limited computing resources in large-scale outdoor scenes. Frustum based 3D object detector first detects 2D objects in the image and then extracts frustum point cloud according to the cross-calibration parameters. Small-scale frustum point clouds can be used for 3D object detection, hence substantially accelerating the computation. However, when objects are missed in the first stage image based detector, the whole algorithm will fail to detect them. In this paper, we extended the frustum based 3D object detector by leveraging more sensor modalities. Our method combines two frustum based 3D object detecting branches in which visible light image and thermal image are used for 2D ROI extracting respectively. After obtaining 3D object proposals from the two branches, 3D non-maximum suppression is conducted to get the final detections. Experiments tested on our experimental autonomous vehicle show that our proposed method is capable of detecting 3D objects fast in various complex environments.","PeriodicalId":129324,"journal":{"name":"2023 IEEE Conference on Artificial Intelligence (CAI)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122688201","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}

Traditional cuff-based BP measurement with equipment like sphygmomanometers is uncomfortable and discontinued. Cuffless BP monitoring using photoplethysmography (PPG) signals has become an area of interest in the research community, particularly with the advent of wearables such as the Apple Watch and Xiaomi Band. While most wearable PPG signals are obtained from the wrist, the most widely used benchmark dataset, the MIMIC dataset, collects PPG signals from the finger. In this study, we collected PPG signals from both finger and wrist locations from 71 participants and compared their similarities and differences. Our results show that the quality of finger PPG signals is superior to that of wrist PPG signals. Additionally, transferring PPG signals from the finger to the wrist is more successful than transferring signals from the wrist to the finger. These findings make it possible to use the publicly available MIMIC dataset to predict BP from smartwatches. This study bridges the gap between academia and industry, and is an important step towards developing continuous BP monitoring for better management of cardiac health.","PeriodicalId":129324,"journal":{"name":"2023 IEEE Conference on Artificial Intelligence (CAI)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116778889","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}

To address this challenge, this paper proposes a feature disentanglement approach to learn the domain-invariant features to achieve domain generalization. The adaptive instance normalization (AdaIN)-based reconstruction is introduced to preserve the important semantic information. The generalization ability of the proposed method is further improved by using a contrastive loss function based on color augmentation to attract the domain-invariant features and repel the domain-specific features in the feature disentanglement process. The proposed method is evaluated on liver tumor and liver lipid droplet segmentation tasks. The results demonstrate that the proposed method can be applied to unseen datasets scanned by different scanners without significant performance degradation.","PeriodicalId":129324,"journal":{"name":"2023 IEEE Conference on Artificial Intelligence (CAI)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127320509","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}
