Every day we interact with machine learning systems offering individualized predictions for our entertainment, social connections, purchases, or health. These involve several modalities of data, from sequences of clicks to text, images, and social interactions. This book introduces common principles and methods that underpin the design of personalized predictive models for a variety of settings and modalities. The book begins by revising 'traditional' machine learning models, focusing on adapting them to settings involving user data, then presents techniques based on advanced principles such as matrix factorization, deep learning, and generative modeling, and concludes with a detailed study of the consequences and risks of deploying personalized predictive systems. A series of case studies in domains ranging from e-commerce to health plus hands-on projects and code examples will give readers understanding and experience with large-scale real-world datasets and the ability to design models and systems for a wide range of applications.

Can features extracted from high spatial resolution satellite imagery accurately estimate poverty and economic well-being? This paper investigates this question by extracting object and texture features from satellite images of Sri Lanka, which are used to estimate poverty rates and average log consumption for 1,291 administrative units (Grama Niladhari divisions). The features that were extracted include the number and density of buildings, prevalence of shadows, number of cars, density and length of roads, type of agriculture, roof material, and a suite of texture and spectral features calculated using a nonoverlapping box approach. A simple linear regression model, using only these inputs as explanatory variables, explains nearly 60 percent of poverty headcount rates and average log consumption. In comparison, models built using night-time lights explain only 15 percent of the variation in poverty or income. The predictions remain accurate when restricting the sample to poorer Gram Niladhari divisions. Two sample applications, extrapolating predictions into adjacent areas and estimating local area poverty using an artificially reduced census, confirm the out-of-sample predictive capabilities.

Das Verstehen menschlichen Verhaltens ist essenziell für intelligente technische Systeme in menschlichen Umgebungen. Diese Arbeit befasst sich mit der videobasierten Aktivitätsanalyse. Dazu werden zwei Methoden der Merkmalsextraktion untersucht: ein markerloses dreidimensionales Körpertracking mit einem evolutionären Algorithmus und ein modellfreies Tracking dynamischer Videomerkmale. Anschließend erfolgt eine Modellierung und Klassifikation von Aktivitäten auf Basis der gewonnenen Merkmale. Understanding human behavior is crucial for intelligent technical systems in human environments. In this work, methods for human activity recognition based on video data are developed. Two approaches of feature extraction are pursued: a method of markerless articulated pose estimation using an evolutionary algorithm and a model-free feature tracking method. The resulting motion representations are then used for modeling and classifying different activities.
