This book introduces empirical methods for Machine Learning with a special focus on applications in Natural Language Processing (NLP) and Data Science. The authors present problems of validity, reliability, and significance and provide common solutions based on statistical methodology to solve them. The book focuses on model-based empirical methods where data annotations and model predictions are treated as training data for interpretable probabilistic models from the well-understood families of generalized additive models (GAMs) and linear mixed effects models (LMEMs). Based on the interpretable parameters of the trained GAMs or LMEMs, the book presents model-based statistical tests such as a validity test that allows for the detection of circular features that circumvent learning. Furthermore, the book discusses a reliability coefficient using variance decomposition based on random effect parameters of LMEMs. Lastly, a significance test based on the likelihood ratios of nested LMEMs trained on the performance scores of two machine learning models is shown to naturally allow the inclusion of variations in meta-parameter settings into hypothesis testing, and further facilitates a refined system comparison conditional on properties of input data. The book is self-contained with an appendix on the mathematical background of generalized additive models and linear mixed effects models as well as an accompanying webpage with the related R and Python code to replicate the presented experiments. The second edition also features a new hands-on chapter that illustrates how to use the included tools in practical applications.

Many organizations today analyze and share large, sensitive datasets about individuals. Whether these datasets cover healthcare details, financial records, or exam scores, it's become more difficult for organizations to protect an individual's information through deidentification, anonymization, and other traditional statistical disclosure limitation techniques. This practical book explains how differential privacy (DP) can help. Authors Ethan Cowan, Michael Shoemate, and Mayana Pereira explain how these techniques enable data scientists, researchers, and programmers to run statistical analyses that hide the contribution of any single individual. You'll dive into basic DP concepts and understand how to use open source tools to create differentially private statistics, explore how to assess the utility/privacy trade-offs, and learn how to integrate differential privacy into workflows. The OpenDP Library is part of the larger OpenDP Project. OpenDP is a community effort to build a trustworthy suite of open-source tools for enabling privacy-protective analysis of sensitive personal data, focused on a library of algorithms for generating differentially private statistical releases. The target use cases for OpenDP are to enable government, industry, and academic institutions to safely and confidently share sensitive data to support scientifically oriented research and exploration in the public interest. We aim for OpenDP to flexibly grow with the rapidly advancing science of differential privacy, and be a pathway to bring the newest algorithmic developments to a wide array of practitioners. SmartNoise is a collaboration between Microsoft, Harvard’s Institute for Quantitative Social Science (IQSS), and the OpenDP Project. The project aims to connect solutions from the research community with the lessons learned from real-world deployments to make differential privacy broadly accessible. Building upon the foundation of the OpenDP Library, the SmartNoise SDK includes two Python packages: smartnoise-sql and smartnoise-synth.

This textbook introduces the theoretical foundations of technologies essential for knowledge graphs. It also covers practical examples, applications and tools. Knowledge graphs are the most recent answer to the challenge of providing explicit knowledge about entities and their relationships by potentially integrating billions of facts from heterogeneous sources. The standard narrative about the recent history of Artificial Intelligence (AI) is that a combination of rapidly growing compute power and an immense increase in available data have caused a scaling explosion in AI that has led to the results in Machine Learning (ML) in the past decade. Indeed, this narrative is true, and the results of the ML explosion are clear for all to see, in the popular press, in scientific publications, and in real world applications, ranging from product recommendation to fraud detection and from chatbots to face recognition. What is rather less known to the general public, the popular press, and indeed in AI itself is that a similar scaling explosion has taken place in another area of AI. The main driver for this “other explosion” of size in AI has been the adoption of the knowledge graph model, combined with ontology languages that carefully balance expressivity against computational cost. Knowledge graphs now form the biggest knowledge bases ever built, and without a doubt, languages like RDF Schema and OWL are by far the most widely used knowledge representation languages in the history of AI. And these knowledge graphs have come of age. They are used in science, in public administration, in cultural heritage, in healthcare, and in a broad range of industries, ranging from manufacturing to financial services and from search engines to pharmaceuticals. This textbook is intended for graduate courses covering knowledge graphs. Besides students in knowledge graph, Semantic Web, database, or information retrieval classes, also advanced software developers for Web applications or tools for Web data management will learn about the foundations and appropriate methods.

For every exercise I did my best to connect the specific statistical concepts with R code, and every time I use linear algebra I connect it with a concrete R example. In this book you will not find something such as "this is left as an exercise to the reader". This book aims to get straight to the point, and the only thing I assume here is that you have used spreadsheets at some point and that you are motivated to estimate linear models in R. Here I do not assume that you know how to install R or the basics of the R programming language. This books contains no proofs. I tried to replace those with multiple examples consisting in analyzing my own experiments, such as throwing a tennis ball and measuring the time it takes to hit the ground from different heights, and another where I got two thermometers and measured the temperature outside a building at the same time of the day on different days.

MATLAB For Engineers starts at the beginning to introduce first-year engineering students to MATLAB. Starting with basic algebra, you'll learn how MATLAB can be used to solve a wide range of engineering problems. Examples taken from concepts presented in early chemistry, physics, and first- and second-year engineering classes are included. When the text covers new subjects, like statistics and matrix algebra, brief background information is used to support your success. As you work through hands-on examples and exercises, you'll learn to apply a consistent problem-solving methodology to help you reach a solution. The 6th Edition reflects the MATLAB software release R2021B. Updated screenshots, new data, new problems and discussions offer a current view of the coding language and platform you'll use in your classes and career. MATLAB is a “multiparadigm” programming language, which means it can be used in several different ways to perform programming tasks. Those tasks can range from something as simple as balancing your checkbook to complex engineering modeling applications. MATLAB is a versatile language, but it can’t do everything. It is a large application program designed to optimize mathematical calculations; number-crunching is where it shines. You wouldn’t want to use it to write a word-processing program, for example. If you wanted to write an operating system or design software, C ++, Java, or some other higher-level language would be a better choice. In fact, MATLAB was originally written in Fortran and then later rewritten in C.
