    In this paper, we introduce a mobile application called CarSafe, in which data from the acceleration sensor integrated on smartphones is exploited to come up with an efficient classification algorithm. Two statuses, "Driving" or "Not driving," are monitored in the real-time manner. It enables automatic actions to help the driver safer. Also, from these data, our software can detect the crash situation. The software will then automatically send messages with the user's location to their emergency departments for timely assistance. The application will also issue the same alert if it detects a driver of a vehicle driving too long. The algorithm's quality is assessed through an average accuracy of 96.5%, which is better than the previous work (i.e., 93%)

    Penentuan komoditas unggulan pada suatu daerah merupakan hal yang sangat penting untuk dilakukan, salah satunya di Provinsi Riau. Memahami mengenai prioritas perencanaan pengembangan wilayah yang diarahkan pada pengembangan komoditas unggulan. Sejauh ini Provinsi Riau memiliki potensi komoditas disektor perkebunan yang sangat menjajikan, data yang ada sebelumnya banyak digunakan sebagai laporan, dalam bentuk data excel. Data komoditas bisa digali dengan teknik data mining untuk mendapatkan pola klasifikasi, sehingga lebih memudahkan Pemerintah Provinsi Riau dalam mendapatkan informasi komoditas unggulannya. Pada penelitian ini, dilakukan pengujian kinerja algoritma klasifikasi yang banyak digunakan dalam data mining, agar mendapatkan algoritma yang memiliki kinerja paling baik untuk klasifikasi data komoditas. Beberapa penelitian mengatakan algoritma klasifikasi C4.5 memiliki kinerja kurang baik dibandingkan dengan algoritma yang lain seperti random forest, dan gradient boosting. Dalam penelitian ini dilakukan perbandingan antara algoritma C4.5, random forest, dan gradient boosting, untuk mengukur kinerja terbaik dalam melakukan klasifikasi data komoditas. Data yang digunakan dalam penelitian ini yaitu data komoditas perkebunan Provinsi Riau pada tahun 2019. Hasil dari penelitian ini, algoritma yang memiliki kinerja terbaik untuk  klasifikasi adalah algoritma random forest dengan syarat menggunakan shuffle sampling. Dan mayoritas linear sampling menghasilkan kinerja kurang baik. Sedangkan shuffle sampling memiliki kinerja sangat baik untuk algoritma berbasis tree

    Phone Laser Scanner becomes the versatile sensor module that is premised on Lamp Identification and Spanning methodology and is used in a spectrum of uses. There are several prior editorials in the literary works that concentrate on the implementations or attributes of these processes; even so, evaluations of all those inventive computational techniques reported in the literature have not even been performed in the required thickness. At ToAT that finish, we examine and summarize the latest advances in Artificial Intelligence based machine learning data processing approaches such as extracting features, fragmentation, machine vision, and categorization. In this survey, we have reviewed total 48 papers based on an enhanced AI based machine learning model for accurate classification and segmentation methods. Here, we have reviewed the sections on segmentation and classification of images based on machine learning models

    A decision tree is a well-known machine learning technique. Recently their popularity has increased due to the powerful Gradient Boosting ensemble method that allows to gradually increasing accuracy at the cost of executing a large number of decision trees. In this paper we present an accelerator designed to optimize the execution of these trees while reducing the energy consumption. We have implemented it in an FPGA for embedded systems, and we have tested it with a relevant case-study: pixel classification of hyperspectral images. In our experiments with different images our accelerator can process the hyperspectral images at the same speed at which they are generated by the hyperspectral sensors. Compared to a high-performance processor running optimized software, on average our design is twice as fast and consumes 72 times less energy. Compared to an embedded processor, it is 30 times faster and consumes 23 times less energy

    A Comprehensive Review of the GNSS with IoT Applications and Their Use Cases with Special Emphasis on Machine Learning and Deep Learning Models

    This paper presents a comprehensive review of the Global Navigation Satellite System (GNSS) with Internet of Things (IoT) applications and their use cases with special emphasis on Machine learning (ML) and Deep Learning (DL) models. Various factors like the availability of a huge amount of GNSS data due to the increasing number of interconnected devices having low-cost data storage and low-power processing technologies - which is majorly due to the evolution of IoT - have accelerated the use of machine learning and deep learning based algorithms in the GNSS community. IoT and GNSS technology can track almost any item possible. Smart cities are being developed with the use of GNSS and IoT. This survey paper primarily reviews several machine learning and deep learning algorithms and solutions applied to various GNSS use cases that are especially helpful in providing accurate and seamless navigation solutions in urban areas. Multipath, signal outages with less satellite visibility, and lost communication links are major challenges that hinder the navigation process in crowded areas like cities and dense forests. The advantages and disadvantages of using machine learning techniques are also highlighted along with their potential applications with GNSS and IoT

    Hybrid Neighbourhood Component Analysis with Gradient Tree Boosting for Feature Selection in Forecasting Crime Rate

    Get PDF
    Crime forecasting is beneficial as it provides valuable information to the government and authorities in planning an efficient crime prevention measure. Most criminology studies found that influence from several factors, such as social, demographic, and economic factors, significantly affects crime occurrence. Therefore, most criminology experts and researchers' study and observe the effect of factors on criminal activities as it provides relevant insight into possible future crime trends. Based on the literature review, the applications of proper analysis in identifying significant factors that influence crime are scarce and limited. Therefore, this study proposed a hybrid model that integrates Neighbourhood Component Analysis (NCA) with Gradient Tree Boosting (GTB) in modelling the United States (US) crime rate data. NCA is a feature selection technique used in this study to identify the significant factors influencing crime rate. Once the significant factors were identified, an artificial intelligence technique, i.e., GTB, was implemented in modelling the crime data, where the crime rate value was predicted. The performance of the proposed model was compared with other existing models using quantitative measurement error analysis. Based on the result, the proposed NCA-GTB model outperformed other crime models in predicting the crime rate. As proven by the experimental result, the proposed model produced the smallest quantitative measurement error in the case study
