Causal Inference for Data Science
by Aleix Ruiz de Villa RobertWhen you know the cause of an event, you can affect its outcome. This accessible introduction to causal inference shows you how to determine causality and estimate effects using statistics and machine learning.A/B tests or randomized controlled trials are expensive and often unfeasible in a business environment. Causal Inference for Data Science reveals the techniques and methodologies you can use to identify causes from data, even when no experiment or test has been performed. In Causal Inference for Data Science you will learn how to: • Model reality using causal graphs • Estimate causal effects using statistical and machine learning techniques • Determine when to use A/B tests, causal inference, and machine learning • Explain and assess objectives, assumptions, risks, and limitations • Determine if you have enough variables for your analysis It&’s possible to predict events without knowing what causes them. Understanding causality allows you both to make data-driven predictions and also intervene to affect the outcomes. Causal Inference for Data Science shows you how to build data science tools that can identify the root cause of trends and events. You&’ll learn how to interpret historical data, understand customer behaviors, and empower management to apply optimal decisions. About the technology Why did you get a particular result? What would have lead to a different outcome? These are the essential questions of causal inference. This powerful methodology improves your decisions by connecting cause and effect—even when you can&’t run experiments, A/B tests, or expensive controlled trials. About the book Causal Inference for Data Science introduces techniques to apply causal reasoning to ordinary business scenarios. And with this clearly-written, practical guide, you won&’t need advanced statistics or high-level math to put causal inference into practice! By applying a simple approach based on Directed Acyclic Graphs (DAGs), you&’ll learn to assess advertising performance, pick productive health treatments, deliver effective product pricing, and more.

Causality for Artificial Intelligence: From a Philosophical Perspective
by Jordi VallverdúHow can we teach machine learning to identify causal patterns in data? This book explores the very notion of “causality”, identifying from a naturalistic and evolutionary perspective how living systems deal with causal relationships. At the same time, using this knowledge to identify the best ways to apply such biological models in machine learning scenarios. One of the more fundamental challenges for AI experts is to design machines that can understand the world, identifying the basic rules that govern reality. Statistics are powerful and fundamental for this process, but they are only one of the necessary tools. Counterfactual thinking is the other part of the necessary process that will help machines to become intelligent. This book explains the paths that can lead to algorithmic causality. It is essential reading for those who are not afraid of thinking at the interface of various academic disciplines or fields (AI, machine learning, philosophy, neuroscience, anthropology, psychology, computer sciences), and who are interested in the analysis of causal thinking and the ways in which cognitive systems (natural or artificial) can act in order to understand their environment. Professor Vallverdú is currently working on biomimetic cognitive architectures and multicognitive systems. His research has explored two main areas: epistemology and cognition. Since his early Ph.D. research on epistemic controversies, he has analyzed several aspects of computational epistemology. His latest research has focused on the causal challenges of machine learning techniques, particularly deep learning. One of his most promising advances is statistics meets causal graph reasoning (via Directed Acyclic Graphs), which still has several conceptual paths that need to be explored and identified. Counterfactual reasoning is a fundamental part of these open debates, which are under the analysis of Prof. Vallverdú. His current research is supported as part of the following projects: GEHUCT and ICREA Acadèmia.
Causality, Meaningful Complexity and Embodied Cognition (Theory and Decision Library A: #46)
by A. CarsettiWith respect to the possible outlining of new models of the process of knowledge construction, we are really faced, at the moment, with the appearance of a new frontier: a frontier that appears strictly linked to the emergence of a conceptual revolution at the level of the analysis of that peculiar entanglement of complexity, information, causality, meaning, emergence, teleology and intentionality that characterizes the unfolding of the "natural forms" of human cognition. To recognize some of the peculiar knots of this particular conceptual revolution precisely constitutes the first target of the volume. Cognitive activity is rooted in Reality, but at the same time represents the necessary means whereby Reality can embody itself in an objective way: i.e., in accordance with an in-depth nesting process and a surface unfolding of operational meaning. In this sense, the objectivity of Reality is also proportionate to the autonomy reached by cognitive processes. Within this conceptual framework, reference procedures thus appear as related to the modalities providing the successful constitution of the channel, of the actual link, in particular, established at the neural level between operations of vision and thought. Such procedures ensure not a simple "regimentation" or an adequate replica, but, on the contrary, the real constitution of a cognitive autonomy in accordance with the truth. A method thus emerges which is simultaneously project, telos and regulating activity: a code that becomes process, positing itself as the foundation of a constantly renewed synthesis between function and meaning. In this sense, at the level of cultural evolution, reference procedures act as guide, mirror and canalisation with respect to primary information flows and involved selective forces. They also constitute a precise support for the operations which "imprison" meaning and "inscribe" the "file" considered as an autonomous categorial (and generating) system. In this way, they offer themselves as the actual instruments for the constant renewal of the code, for the invention and the actual articulation of an ever-new incompressibility.
Causality, Probability, and Time
by Samantha KleinbergCausality is a key part of many fields and facets of life, from finding the relationship between diet and disease to discovering the reason for a particular stock market crash. Despite centuries of work in philosophy and decades of computational research, automated inference and explanation remains an open problem. In particular, the timing and complexity of relationships has been largely ignored even though this information is critically important for prediction, explanation, and intervention. However, given the growing availability of large observational datasets including those from electronic health records and social networks, it is a practical necessity. This book presents a new approach to inference (finding relationships from a set of data) and explanation (assessing why a particular event occurred), addressing both the timing and complexity of relationships. The practical use of the method developed is illustrated through theoretical and experimental case studies, demonstrating its feasibility and success.
Cause Effect Pairs in Machine Learning (The Springer Series on Challenges in Machine Learning)
by Isabelle Guyon Alexander Statnikov Berna Bakir BatuThis book presents ground-breaking advances in the domain of causal structure learning. The problem of distinguishing cause from effect (“Does altitude cause a change in atmospheric pressure, or vice versa?”) is here cast as a binary classification problem, to be tackled by machine learning algorithms. Based on the results of the ChaLearn Cause-Effect Pairs Challenge, this book reveals that the joint distribution of two variables can be scrutinized by machine learning algorithms to reveal the possible existence of a “causal mechanism”, in the sense that the values of one variable may have been generated from the values of the other. This book provides both tutorial material on the state-of-the-art on cause-effect pairs and exposes the reader to more advanced material, with a collection of selected papers. Supplemental material includes videos, slides, and code which can be found on the workshop website.Discovering causal relationships from observational data will become increasingly important in data science with the increasing amount of available data, as a means of detecting potential triggers in epidemiology, social sciences, economy, biology, medicine, and other sciences.
Cause-Effect Structures: An Algebra of Nets with Examples of Applications (Lecture Notes in Networks and Systems #45)
by Ludwik CzajaThis book presents a new algebraic system whose interpretation coincides with the behaviour of Petri nets, enhanced with an inhibitory mechanism and four time models. Its goal is to provide a formal means of modelling dynamic tasks, and of testing and verifying properties, in contexts characterised by the parallel execution of actions. However, the task description differs from that of Petri nets. The algebra is a quasi-semiring, “quasi” because of its somewhat restricted distributivity axiom. Expressions of this algebra, the cause–effect structures, have a graphic presentation as nets, but with one kind of named nodes, each annotated by two expressions that specify the type of signal reception from predecessors and transmission to successors. Many structural and behavioural properties are stated with proofs, and illustrative sample tasks are included. The book is intended for all those interested or involved in parallel and distributed computing – students, researchers and practitioners alike.

Causes And Consequences Of Map Generalization
by Elsa JoaoThis text describes late-1990s understanding of map generalisation in the context of paper maps and GIS. Its particular value should be in helping to further automate and measure the process of map generalisation.; The research has concentrated on quantifying generalisation effects and on analysing how these effects of generalisation locked into the maps were measured. Elsa Joao's book covers the background to the problems of map generlasation; the methodology developed by the author to investigate the consequences of the map generalisation; a detailed description of results, and a conclusion that draws together consequences for the broader applications to GIS.
Causes and Symptoms of Socio-Cultural Polarization: Role of Information and Communication Technologies
by Israr Qureshi Babita Bhatt Samrat Gupta Amit Anand TiwariThis book explores cultural polarization resultant decline in social cohesion in society and how information and communication technologies exacerbate the cultural polarization through phenomenon such as “echo chambers” of information that damage the quality of online discourse. This book examines the nature of the information that is shared. Further this book identifies how the quality of online discourse and polarization induced through it leads to offline harm and negative outcomes in our society. This book discusses how wide-ranging information exchange on digital media can lead to two scenarios, namely, the formation of the public sphere or the formation of echo chambers. While the public sphere, which promotes greater diversity, is a well-researched domain, substantially less research has been conducted on echo chambers in relation to sociocultural activities, products or services. This book states that polarization induced by the formation and evolution of echo chambers in sociocultural realm such as around epidemic outbreaks, vaccination, healthcare, education, and climate change is an emerging avenue of research due to its enormous impact in the shaping of our society. Therefore, this book argues that understanding the characteristics of sociocultural products related controversies is critical and valuable in developing interventions to reduce unhealthy societal and organizational polarisations. The development of systematic knowledge is required to understand and address such a large scale and complex societal challenge so as to facilitate a deeper understanding and offer solutions to the growing issue of polarization in sociocultural context driven primarily through echo chambers. This book examines how technology enabled social media usage increases, and the complex structural outcomes such as echo chambers are likely to have an increasingly important role in shaping public opinion. This book appeals to readers with interest in developing a deeper and broader understanding of issues and initiatives related to the polarization of opinions on cultural products. These include readers and scholars from various disciplines, along with engaged organizational leaders, activists, policy makers, and common citizens.
