The A2C RL can improve the hyperparameter selection such that the resulting accuracy of machine learning (ML) algorithms including XGBoost, support vector classifier (SVC), random forest shows comparable. According to the specified accuracy of the ML algorithms, the early stopping scheme can save the computation cost. Ten standard datasets are used to valid the accuracy-time efficient HPO. Experimental results show that the presented accuracy-efficient HPO architecture can improve 0.77% accuracy on average compared with default hyperparameter for random forest. The early stopping can save 64% computation cost on average compared to without early stopping for random forest.","PeriodicalId":138894,"journal":{"name":"2022 IEEE International Conference on Internet of Things and Intelligence Systems (IoTaIS)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121512484","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}

This study presents a novel, computationally efficient and robust approach for fully field-integrated, low-complexity and high-accuracy classification of olives variety and location of origin, based on genetic ‘fingerprinting’ via a minimal set of information-rich features.

Caregivers, such as oncologists and radiologists, however, need to understand the nature of the model outcome. We address this in this paper by providing an end-to-end explainable AI framework for analyzing breast cancer prediction models based on a publicly available mammography dataset.

In this paper, we address this topic, and among the numerous multi-stage chronic diseases, we select the breast cancer use-case due to the importance of breast cancer patients survivability analysis and prediction for healthcare providers to make informed decisions on recommended treatment pathways for different patients. Then, we combine two main strategies in solving the breast cancer survivability prediction problem using Machine Learning techniques. In the first strategy, we model the survivability prediction task as a two-step problem, namely 1) a classification problem to predict whether or not a patient survives for five years, and 2) a regression problem to forecast the number of remaining months for those who are predicted to not survive for five years. The second strategy is to develop stage-specific models, where each model is trained on instances belonging to a certain cancer stage, instead of using all stages together, in order to predict survivability of patients from the same stage. We investigate the impact of adapting these strategies along with applying different balancing techniques over the model performance using the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) dataset. The obtained results demonstrate that the proposed methods prove effective in both survivability classification and regression.","PeriodicalId":138894,"journal":{"name":"2022 IEEE International Conference on Internet of Things and Intelligence Systems (IoTaIS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114253646","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}

Existing works have been focused on developing accurate anomaly detection models. However, due to the resource-constrained nature of IoT networks and the requirement of real-time security operation, cost efficient (regarding computational efficiency and memory-consumption efficiency) approaches for anomaly detection are highly desirable in IoT applications. In this paper, we investigated machine learning (ML) enabled anomaly detection models for the IoT with regard to multi-objective optimization (Pareto optimization) that minimizes the detection error, execution time, and memory consumption simultaneously. Making use of well-known datasets consisting of network traffic traces captured in an IoT environment, we studied a variety of machine learning algorithms through the world-class H2O AI platform. Our experimental results show that the Gradient Boosting Machine, Random Forest, and Deep Learning models are the most accurate and fastest anomaly detection models; the Gradient Boosting Machine and Random Forest are the most accurate and memory-efficient models. These ML models form the Pareto-optimal set of anomaly detection models. Our results can be used by the industry to facilitate their selection of ML models for anomaly detection on various IoT networks based on their security requirements and system constraints.","PeriodicalId":138894,"journal":{"name":"2022 IEEE International Conference on Internet of Things and Intelligence Systems (IoTaIS)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124919822","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}

In this study, we elaborate on fog based design for a scalable real time air quality monitoring and alert generation system. We established an emulation test bed with real data collected from air quality sensing nodes deployed around Bangkok and vicinity areas to understand the behavior of the proposed solution in terms of waiting time characteristics. We analyzed the performance of the system in two design scenarios; first scenario is built with the proposed fog solution and the second one is the cloud-based approach.

Realizing its importance, the United Nations has identified Health and Wellness as one of the Sustainable Development Goals (SDG). The unfortunate pandemic situation due to the COVID-19 outbreak opened up new challenges for contact-less interactions and control of devices for ensuring the well being of citizens. In this paper, our main aim is to develop an intelligent framework based on a gesture-based interface that will help the senior citizens and physically challenged people interact and control different devices using only gestures. We focus on dynamic gesture recognition using a deep learning-based Convolutional Neural Network (CNN) model. The proposed system records continuous real-time data streams from non-invasive wearable sensors. This real-time continuous data stream is fragmented into data segments that are most likely to contain meaningful gesture data frames using the Adaptive Threshold Setting algorithm. The segmented data frames are provided as input to the CNN model to train, test, validate, and then classify it into predefined clusters, which are gestures. We have used the MPU6050 Inertial Measurement Unit based sensor model for collecting the data of the hand/ finger movement. The popular and widely used ESP8266 controller is used for data gathering, processing, and communicating. We created a dataset for 36 gestures, which includes ten digits and 26 English alphabets. For each gesture, a dataset of 300 samples has been created from 5 subjects of age group between 21-30. Thus, the final dataset consists of a total of 10800 samples belonging to 36 gestures. A total of six features comprising linear accelerations and angular rotation in 3-dimensional axes are used for training and validation. The proposed model can segment 93.75% of data segments correctly using the adaptive threshold selection algorithm, and the CNN classification algorithm can classify 98.67% gestures correctly.","PeriodicalId":138894,"journal":{"name":"2022 IEEE International Conference on Internet of Things and Intelligence Systems (IoTaIS)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116417314","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}

Today, on top of their initial communicator role, smart devices act as guides, companions, and aids. For a long time, people have been using navigation systems and mobile phones as navigators in their cars. Indeed, there have been interests in implementing similar indoor navigation systems using technologies such as Wi-Fi, Bluetooth, and ultra-wideband. However, the proposed indoor navigation solutions were either too expensive to implement and maintain, or not accurate enough for a wider acceptance. Accordingly, this paper proposes a hybrid pedestrian dead reckoning (PDR) for indoor navigation, which utilizes the built-in sensors of smart devices. As part of this study, the authors implement three approaches to pedestrian dead-reckoning namely PDR, Personal PDR, and Hybrid P-PDR-and evaluate in a real-world setting. The findings of the the evaluation shows that the Hybrid P-PDR approach, which harnesses the user’s walking pattern and signals from low-energy beacons, can navigate users in an indoor environment with a minimum of 0.77 and maximum of 1.35-meter average distance error.","PeriodicalId":138894,"journal":{"name":"2022 IEEE International Conference on Internet of Things and Intelligence Systems (IoTaIS)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116537293","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}
