Most of the modern machine learning models, based on deep learning techniques, depend on carefully curated and cleanly labelled training sets to be reliably trained and deployed. However, the expensive labelling process involved in the acquisition of such training sets limits the number and size of datasets available to build new models, slowing down progress in the field. Alternatively, many poorly curated training sets containing noisy labels are readily available to be used to build new models. However, the successful exploration of such noisy-label training sets depends on the development of algorithms and models that are robust to these noisy labels.Machine learning and Noisy Labels: Definitions, Theory, Techniques and Solutions defines different types of label noise, introduces the theory behind the problem, presents the main techniques that enable the effective use of noisy-label training sets, and explains the most accurate methods developed in the field.This book is an ideal introduction to machine learning with noisy labels suitable for senior undergraduates, post graduate students, researchers and practitioners using, and researching into, machine learning methods. - Shows how to design and reproduce regression, classification and segmentation models using large-scale noisy-label training sets - Gives an understanding of the theory of, and motivation for, noisy-label learning - Shows how to classify noisy-label learning methods into a set of core techniques

An understanding of the mineral nutrition of plants is of fundamental importance in both basic and applied plant sciences. The fourth edition of this book retains the aim of the first in presenting the principles of mineral nutrition in the light of current advances. Marschner's Mineral Nutrition of Plants, 4th Edition, is divided into two parts: Nutritional Physiology and Plant–Soil Relationships. In Part I, emphasis is put on uptake and transport of nutrients in plants, root–shoot interactions, role of mineral nutrition in yield formation, stress physiology, water relations, functions of mineral nutrients and contribution of plant nutrition to food nutritional quality, disease tolerance, and global nutritional security of human populations. In view of the increasing interest in plant–soil interactions. Part II focuses on the effects of external and internal factors on root growth, rhizosphere chemistry and biology, soil-borne ion toxicities, and nutrient cycling. Now with color figures throughout, this book continues to be a valuable reference for plant and soil scientists and undergraduate and graduate students in the fields of plant nutrition, nutritional physiology, and soil fertility. - Offers new content on the relationship between climate change, soil fertility and crop nutrition - Keeps overall structure of previous editions - Includes updates in every chapter on new developments, ideas and challenges

Boron in Plants and Agriculture: Exploring the Physiology of Boron and Its Impact on Plant Growth highlights the various emerging techniques and applications that are currently being used in plant-boron interaction studies, and provides a direction towards implementation of programs and practices that will enable sustainable production of crops, resilient to boron stress. Boron is an important micronutrient that plays a crucial role in the growth and development of plants, however despite a significant amount of recent research, there has remained a gap in the understanding of boron update and transportation. Boron deficiency is one of the most widespread deficiencies among plant micronutrients in agriculture and it causes a wide range of symptoms including the cessation of root elongation, reduced leaf expansion and the loss of fertility, depending on the plant species and developmental stage. This book reviews and integrates the currently available information on the impact of boron on functional and adaptive features of plants from molecular, biochemical, physiological to whole plant level. It is a key resource for those working in stress physiology, stress proteins, genomics, proteomics, genetic engineering and other fields of plant physiology related to boron nutrition, including agriculture. - Highlights various emerging techniques and applications that are currently being used in plant-boron interaction studies, along with future prospects - Provides direction towards the implementation of programs and practices that will enable sustainable production of crops that are resilient to boron stress - Introduces global leaders working in the area of plant-boron interactions and shares their research findings
