A graphical model is a statistical model that is represented by a graph. The factorization properties underlying graphical models facilitate tractable computation with multivariate distributions, making the models a valuable tool with a plethora of applications. Furthermore, directed graphical models allow intuitive causal interpretations and have become a cornerstone for causal inference.While there exist a number of excellent books on graphical models, the field has grown so much that individual authors can hardly cover its entire scope. Moreover, the field is interdisciplinary by nature. Through chapters by leading researchers from different areas, this handbook provides a broad and accessible overview of the state of the art.Features: Contributions by leading researchers from a range of disciplinesStructured in five parts, covering foundations, computational aspects, statistical inference, causal inference, and applicationsBalanced coverage of concepts, theory, methods, examples, and applicationsChapters can be read mostly independently, while cross-references highlight connectionsThe handbook is targeted at a wide audience, including graduate students, applied researchers, and experts in graphical models.

Discover New Methods for Dealing with High-Dimensional DataA sparse statistical model has only a small number of nonzero parameters or weights; therefore, it is much easier to estimate and interpret than a dense model. Statistical Learning with Sparsity: The Lasso and Generalizations presents methods that exploit sparsity to help recover the underlying signal in a set of data.Top experts in this rapidly evolving field, the authors describe the lasso for linear regression and a simple coordinate descent algorithm for its computation. They discuss the application of ℓ1 penalties to generalized linear models and support vector machines, cover generalized penalties such as the elastic net and group lasso, and review numerical methods for optimization. They also present statistical inference methods for fitted (lasso) models, including the bootstrap, Bayesian methods, and recently developed approaches. In addition, the book examines matrix decomposition, sparse multivariate analysis, graphical models, and compressed sensing. It concludes with a survey of theoretical results for the lasso.In this age of big data, the number of features measured on a person or object can be large and might be larger than the number of observations. This book shows how the sparsity assumption allows us to tackle these problems and extract useful and reproducible patterns from big datasets. Data analysts, computer scientists, and theorists will appreciate this thorough and up-to-date treatment of sparse statistical modeling.

The classic high-level walk from Irish Sea to North SeaOriginally devised by the legendary Alfred Wainwright, the Coast-to-Coast Walk has steadily become one of Britain’ s most popular long-distance walks, and it is not hard to see why. Planned to seek out the most spectacular high ground across the country, it takes you from the sea in the west to the sea in the east via three of England’ s loveliest National Parks: the Lake District, the Yorkshire Dales and the North York Moors. Its 192 miles, from the quiet Cumbrian village of St Bees to Robin Hood’ s Bay, are a substantial test of endurance that will take even a fit walker a fortnight to accomplish, but also a wonderfully varying walk, from sea cliffs to craggy mountains and lakes, then across rolling dales and finally heather moorland. For everyone who reaches Wainwright’ s Bar at journey’ s end on the North Yorkshire coast it will have been the walk of a lifetime.

A charming guide to the story of the English village, celebrating this beloved heart of the countryside.The village remains a quintessential and much-loved treasure that is often representative of England. This rural idyll has inspired generations of great poets, novelists and artists including the likes of Constable, Hardy and Wordsworth.The English Village champions all that is unique and loved about a typical village – the pub, the green, the school, the church, the pond, the local shop and more – as well as exploring how the village has changed over the centuries, and how it has adjusted to modern-day life.A fascinating compendium of interesting details, facts, customs and lore, this is an unabashed toast to the English village, as well as a record of a disappearing world.

Presents an assessment of the redevelopment and regeneration of Leeds. This book identifies the drivers for change in the renaissance of contemporary Leeds following its evolution from Georgian/Victorian times. It explores the depth and complexity of the public-private partnerships involved in the delivery structures and their achievements.If Leeds was good in Arthur Ransome's day, it is hard to find an adjective that describes its fizz and chutzpah at the beginning of the 21st century. The city has been so successful in the last 30 years that its rivals have had to fall back on the insult 'smug', a jibe which, by definition, has little effect on its target. There is a deep-rooted sense of satisfaction, every bit as cosy as Ransome's, in the unofficial capital of Yorkshire. It shows mostly in the attitude of its people but also finds expression in the architecture, and especially in the strong sense of place in the city centre."Leeds: Shaping the City" is an authoritative and objective assessment of the redevelopment and regeneration of Leeds. It identifies the drivers for change in the renaissance of contemporary Leeds following its evolution from Georgian/Victorian times; explores the depth and complexity of the public-private partnerships involved in the delivery structures and their achievements; articulates the importance of urban design for successful regeneration; uses case studies to illustrate the processes involved in the major physical change of the city and to assess their influence on future projects; and, provides a chronology of critical regeneration activities and key events over the last 20 years. Leeds has done exceptionally well in transforming itself from a grimy 'factoryopolis'.There are challenges ahead but the physical expression of Leeds' success - seen everywhere from clubs and cool restaurants to lofts above the inland port, where canal and river entwine - keep stimulating the imagination of new generations of entrepreneurs.
