Take your machine learning expertise to the next level with this essential guide, utilizing libraries like imbalanced-learn, PyTorch, scikit-learn, pandas, and NumPy to maximize model performance and tackle imbalanced dataKey FeaturesUnderstand how to use modern machine learning frameworks with detailed explanations, illustrations, and code samplesLearn cutting-edge deep learning techniques to overcome data imbalanceExplore different methods for dealing with skewed data in ML and DL applicationsPurchase of the print or Kindle book includes a free eBook in the PDF formatBook DescriptionAs machine learning practitioners, we often encounter imbalanced datasets in which one class has considerably fewer instances than the other. Many machine learning algorithms assume an equilibrium between majority and minority classes, leading to suboptimal performance on imbalanced data. This comprehensive guide helps you address this class imbalance to significantly improve model performance.Machine Learning for Imbalanced Data begins by introducing you to the challenges posed by imbalanced datasets and the importance of addressing these issues. It then guides you through techniques that enhance the performance of classical machine learning models when using imbalanced data, including various sampling and cost-sensitive learning methods.As you progress, you'll delve into similar and more advanced techniques for deep learning models, employing PyTorch as the primary framework. Throughout the book, hands-on examples will provide working and reproducible code that'll demonstrate the practical implementation of each technique.By the end of this book, you'll be adept at identifying and addressing class imbalances and confidently applying various techniques, including sampling, cost-sensitive techniques, and threshold adjustment, while using traditional machine learning or deep learning models.What you will learnUse imbalanced data in your machine learning models effectivelyExplore the metrics used when classes are imbalancedUnderstand how and when to apply various sampling methods such as over-sampling and under-samplingApply data-based, algorithm-based, and hybrid approaches to deal with class imbalanceCombine and choose from various options for data balancing while avoiding common pitfallsUnderstand the concepts of model calibration and threshold adjustment in the context of dealing with imbalanced datasetsWho this book is forThis book is for machine learning practitioners who want to effectively address the challenges of imbalanced datasets in their projects. Data scientists, machine learning engineers/scientists, research scientists/engineers, and data scientists/engineers will find this book helpful. Though complete beginners are welcome to read this book, some familiarity with core machine learning concepts will help readers maximize the benefits and insights gained from this comprehensive resource.Table of ContentsIntroduction to Data Imbalance in Machine LearningOversampling MethodsUndersampling MethodsEnsemble MethodsCost-Sensitive LearningData Imbalance in Deep LearningData-Level Deep Learning MethodsAlgorithm-Level Deep Learning TechniquesHybrid Deep Learning MethodsModel CalibrationAppendix

THE MASS MOVEMENTS AMONGTHE OUTCASTES OF INDIAAt different periods in the history of the world great movements come to the birth, fraught with far-reaching consequences to the spiritual progress of mankind. Some within and some without the Church, they serve to inspire the men of vision and faith, and to prove afresh that the government of God is sleeplessly active in the control of the destinies of man.Of such a character are the mass movements among the outcastes of India. For nearly a century these have been spreading over the whole land and gathering force with every decade, until at the present moment they are outstanding features of missions in India.

This book contains high-quality papers presented in the conference Recent Advances in Mechanical Infrastructure (ICRAM 2020) held at IITRAM, Ahmedabad, India, from 21-23 August 2020. The topics covered in this book are recent advances in thermal infrastructure, manufacturing infrastructure and infrastructure planning and design.

Attention! Are you from India and interested in studying abroad in the US, Europe, Australia or Canada? Sick of seeing scholarships only for local residents.Studying in a foreign university in a developed country has long been seen as a gateway to a better standard of living. This is either through the increased knowledge obtained or through the increased job opportunities that result from the knowledge. Universities in Europe, US, Australia and Canada expose all their students to people from different corners of the globe. Students do learn to work with people from different cultural backgrounds as well as learn skills that will make them more employable globally. Of course, it is important that they work hard once they get there and make the right decisions; but they definitely have the opportunity to a better life.However, people from India looking to study abroad have several obstacles that they need to overcome. The biggest burden is the financial one. People from upper middle class and rich families can afford the fees needed for the high grade of education. However, everyone else must scramble. There is the opportunity for graduate research and graduate teaching assistanships. But those who are not able to get these assistanships must rely on loans taken at very high interest rate in Indian banks. Given the cost of foreign education and salaries in India, it is almost impossible to pay off the loan with an Indian salary. So, there is huge pressure to get a job in the country of schooling. This can be difficult as most jobs cater towards those with local citizenship.From personal experiences with study abroad scholarships, I realize that most of the scholarships that are shown to students require citizenship or permanent residence of the local country. When I was at Georgia Tech, there were plenty of scholarships available to local residents of Georgia, USA. Most of the local students could cover their entire tuition with the scholarships. The international students were left hanging. To address this issue, our team looked at several programs, both in India and the developed countries. There are scholarships in USA, Australia, USA and Europe that are specific to students from developing countries to help educate their workforce. There are also scholarships by private and public organizations in India that are for Indian citizens. There are several universities that provide scholarships as well. This book is a compilation of several of the most prominent scholarships that could benefit you in your studies, and make a difference in your life.As a bonus for downloading this book, you will get an extra chapter on how to carry out an effective search for a desired scholarship and tips on how you can write a winning proposal. You will also get tips on how you can avoid being scammed amongst other beneficial insight. I would encourage you to go through the entire book as you may not really know what best suits your academic needs unless you have read all through the book. What's included in this book: List of scholarships for US universities List of scholarships for UK and European universities List of scholarships for Australian Universities List of scholarships for Canadian Universities How to effectively submit an application for a scholarship (Bonus)If this sounds like what you want, then this book is for you.Scroll up and download
