"The current book is the first publication of a complete overview of machine learning methodologies for the medical and health sector. It was written as a training companion, and as a must-read, not only for physicians and students, but also for any one involved in the process and progress of health and health care. In eighty chapters eighty different machine learning methodologies are reviewed, in combination with data examples for self-assessment. Each chapter can be studied without the need to consult other chapters.
The amount of data stored in the world's databases doubles every 20 months, and clinicians, familiar with traditional statistical methods, are at a loss to analyze them. Traditional methods have, indeed, difficulty to identify outliers in large datasets, and to find patterns in big data and data with multiple exposure / outcome variables. In addition, analysis-rules for surveys and questionnaires, which are currently common methods of data collection, are, essentially, missing. Fortunately, the new discipline, machine learning, is able to cover all of these limitations.
So far medical professionals have been rather reluctant to use machine learning. Also, in the field of diagnosis making, few doctors may want a computer checking them, are interested in collaboration with a computer or with computer engineers. Adequate health and health care will, however, soon be impossible without proper data supervision from modern machine learning methodologies like cluster models, neural networks, and other data mining methodologies.
Each chapter starts with purposes and scientific questions. Then, step-by-step analyses, using data examples, are given. Finally, a paragraph with conclusion, and references to the corresponding sites of three introductory textbooks, previously written by the same authors, is given."

"Access to big data, the “new commodity” for the 21st century economies, and its uses and potential abuses, has both conceptual and methodological impacts for the field of comparative and international education. This book examines, from a comparative perspective, the impact of the movement from the so-called knowledge-based economy towards the Intelligent Economy, which is premised upon the application of knowledge. Knowledge, the central component of the knowledge-based economy, is becoming less important in an era that is projected to be dominated and defined by the integration of complex technologies under the banner of the fourth industrial revolution. In this new era that blends the physical with the cyber-physical, the rise of education intelligence means that clients including countries, organizations, and other stakeholders are equipped with cutting-edge data in the form of predicative analytics, and knowledge about global educational predictions of future outcomes and trends. In this sense, this timely volume links the advent of this new technological revolution to the world of governance and policy formulation in education in order to open a broader discussion about the systemic and human implications for education of the emerging intelligent economy. By providing a unique comparative perspective on the Educational Intelligent economy, this book will prove invaluable for researchers and scholars in the areas of comparative education, artificial intelligence and educational policy."

"This volume offers comprehensive coverage of state-of-the-art ensemble learning techniques, including the random forest skeleton tracking algorithm in the Xbox Kinect sensor, which bypasses the need for game controllers. At once a solid theoretical study and a practical guide, the volume is a windfall for researchers and practitioners alike. "

"Peralatan Perangkat Pelepas Tekanan (PRD) dioperasikan dengan tujuan untuk melindungi kehidupan dan keselamatan dalam suatu sistem bertekanan. Peralatan akan mengalami penurunan kondisi seiring berjalannya waktu pemakaian. Ketidakmampuan PRD untuk melakukan fungsinya perlu diidentifikasi sebagai mode kegagalan. Untuk mengurangi risiko apabila terjadi kegagalan, suatu pendekatan seperti Risk Based Inspection (RBI) dapat dilakukan. Metode RBI yang umum digunakan masih menggunakan pendekatan kualitatif, sehingga menghasilkan variasi yang cukup besar. Penelitian ini mengusulkan metode analisa risiko dengan menggunakan pembelajaran mesin berbasis deep learning untuk mengembangkan suatu model penilaian risiko pada PRD akibat mode kegagalan fail on demand (POFOD) yang diharapakan dapat mempersingkat waktu, meningkatkan akurasi, efisiensi dalam pengolahan data hasil inspeksi, serta biaya; dengan menawarkan hasil akurasi perhitungan yang tinggi. Penelitian ini menghasilkan program prediksi risiko dengan menggunakan metode klasifikasi pembelajaran mesin berbasis deep learning akibat mode kegagalan fail on demand pada peralatan perangkat pelepas tekanan. Pembuatan dataset yang digunakan pada model bersumber dari 160 data yang diolah dengan menggunakan standar API 581. Penelitian ini menggunakan beberapa parameter model seperti test size sebesar 20%, random state bernilai 0, penggunaan jumlah epoch sebesar 150, learning rate sebesar 0.001, dan layer berjumlah 3 dengan dense 64,64,8; yang menghasilkan akurasi model sebesar 91%, dari validasi confusion matrix.

Pressure Relief Device (PRD) equipment is operated with the aim of protecting the lives and safety within a pressurized system. An equipment experiences deterioration over time. The inability of PRD equipment to perform its design function needs to be identified as a failure mode. To reduce the risk in case of failure, an approach such as Risk Based Inspection (RBI) can be implemented. The commonly used RBI methods still rely on qualitative approaches, leading to significant variations. This research proposes a method using deep learning to develop a risk assessment model for PRD due to the failure on demand. This is expected to shorten the assessment time, improve accuracy, efficiency, and reduce costs by offering highly accurate calculation results. This research produces a risk prediction program using a deep learning classification method for POFOD in pressure relief device equipment. The dataset used in the model consists of 160 data processed according to API 581 standards. This research utilizes several model parameters, including a test size of 20%, 0 value of random state, 150 epochs, a learning rate of 0.001, and 3 layers with dense of 64, 64, 8. The model achieves an accuracy of 91% from the validation confusion matrix."

"Saat ini geosaintis memasuki era big data dan pembelajaran mesin memberikan potensi besar untuk berkontribusi dalam masalah geosains (Karpatne dkk., 2017). Automasi dalam analisis fasies perlu dilakukan untuk meningkatkan keakuratan, juga mengurangi waktu dan biaya dalam kegiatan pengembangan sumur sehingga dapat meningkatkan hasil produksi. Penelitian dilakukan menggunakan data log sumur pengeboran, laporan deskripsi batuan inti, dan deskripsi petrografi di reservoir gas Lapangan X. Akumulasi gas berada di reservoir utama hasil endapan vulkaniklastik pada Formasi Pucangan. Proses pengelompokan dilakukan menggunakan algoritma K-Means dan di analisis menggunakan Cutoff Crossplot. Kemudian dilanjutkan dengan klasifikasi yang dilakukan menggunakan pembelajaran tersupervisi dengan jenis algoritmaSupport Vector Machine (SVM), Random Forest, dan Extreme Gradient Boosting (XGBoost). Lokasi penelitian berada di wilayah kerja Minarak Brantas Gas Inc (MBGI) Kabupaten Sidoarjo, Jawa Timur. Lapangan X terletak pada reservoir vulkaniklastikberumur Pleistosen dan terletak di onshore Cekungan Jawa Timur. Interval produksi berada di bagian bawah yang terendapkan di lingkungan neritik luar atau lingkungan turbiditik. Lapangan X terdiri dari empat fasies yaitu, batulempung, batulanau, batupasirvulkanik, dan batupasir karbonatan. Algoritma pembelajaran mesin yang paling baik digunakan untuk identifikasi fasies pada Lapangan X adalah RandomForest dengan hasil akurasi f1-score tertinggi, dan nilai RMSE (Root Mean Square Error) paling rendah dibandingkan kedua algoritma lain.

Geoscientists are currently entering the era of big data and machine learning provides great potential to contribute to geoscience problems (Karpatne et al., 2017). Automation in facies analysis needs to be done to increase accuracy, also reduce time and costs in well development activities so as to increase production yields. The research was conducted using drilling well log data, core rock description reports, and petrographic descriptions of gas reservoirs in Field X. Gas accumulation is in the main reservoir as a result of volcaniclastic deposits in the Pucangan Formation. The clustering process was carried out using the K-Means algorithm and analyzed using the Cutoff Crossplot. Then proceed with the classification which is carried out using supervised learning with the types of Support Vector Machine (SVM), Random Forest, and Extreme Gradient Boosting (XGBoost) algorithms. The research location is in the working area of ​​Minarak Brantas Gas Inc. (MBGI) Sidoarjo Regency, East Java. Field X is in a Pleistocene volcaniclastic reservoir and is locatedonshore in the East Java Basin. The production interval is at the bottom which is deposited in an outer neriticenvironment or a turbiditic environment. Field X consists of four facies, namely, claystone, siltstone, volcanic sandstone, and carbonate sandstone. The bestmachine learning algorithm used for faciesidentification in Field X is Random Forest with thehighest f1-score accuracy, and the lowest RMSE (RootMean Square Error) value compared to the other two algorithms.
