An introduction to the techniques and algorithms of the newest field in robotics. Probabilistic robotics is a new and growing area in robotics, concerned with perception and control in the face of uncertainty. Building on the field of mathematical statistics, probabilistic robotics endows robots with a new level of robustness in real-world situations. This book introduces the reader to a wealth of techniques and algorithms in the field. All algorithms are based on a single overarching mathematical foundation. Each chapter provides example implementations in pseudo code, detailed mathematical derivations, discussions from a practitioner's perspective, and extensive lists of exercises and class projects. The book's Web site, www.probabilistic-robotics.org, has additional material. The book is relevant for anyone involved in robotic software development and scientific research. It will also be of interest to applied statisticians and engineers dealing with real-world sensor data.
Lifelong learning addresses situations in which a learner faces a series of different learning tasks providing the opportunity for synergy among them. Explanation-based neural network learning (EBNN) is a machine learning algorithm that transfers knowledge across multiple learning tasks. When faced with a new learning task, EBNN exploits domain knowledge accumulated in previous learning tasks to guide generalization in the new one. As a result, EBNN generalizes more accurately from less data than comparable methods. Explanation-Based Neural Network Learning: A Lifelong Learning Approach describes the basic EBNN paradigm and investigates it in the context of supervised learning, reinforcement learning, robotics, and chess. `The paradigm of lifelong learning - using earlier learned knowledge to improve subsequent learning - is a promising direction for a new generation of machine learning algorithms. Given the need for more accurate learning methods, it is difficult to imagine a future for machine learning that does not include this paradigm.' From the Foreword by Tom M. Mitchell.

This monograph describes a new family of algorithms for the simultaneous localization and mapping (SLAM) problem in robotics, called FastSLAM. The FastSLAM-type algorithms have enabled robots to acquire maps of unprecedented size and accuracy, in a number of robot application domains and have been successfully applied in different dynamic environments, including a solution to the problem of people tracking.
Now a major motion picture starring Rooney Mara An epic story of family, love, and unavoidable tragedy from the two-time Booker Prize finalist and author of Old God's Time Sebastian Barry's novels have been hugely admired by readers and critics, and in 2005 his novel A Long Long Way was shortlisted for the Man Booker Prize. In The Secret Scripture, Barry revisits County Sligo, Ireland, the setting for his previous three books, to tell the unforgettable story of Roseanne McNulty. Once one of the most beguiling women in Sligo, she is now a resident of Roscommon Regional Mental Hospital and nearing her hundredth year. Set against an Ireland besieged by conflict, The Secret Scripture is an engrossing tale of one woman's life, and a poignant story of the cruelties of civil war and corrupted power. The Secret Scripture is now a film starring Rooney Mara, Eric Bana, and Vanessa Redgrave.
Celebrated children's writer Hans Christian Andersen arrives, unannounced, for a stay at Gad's Hill Place in the Kent marshes - home to Charles Dickens and his large, charismatic family. To the lonely and eccentric guest, the members of Dickens' household seem to live a life of unreachable bliss. But with his broken English, Andersen doesn't at first see the storms brewing within the family: undeclared passions, a son about to go to India, and a growing strangeness at the heart of Dickens' marriage. Andersen's English by Sebastian Barry premiered at the Theatre Royal, Bury, in February 2010 in a production by Out of Joint.
COSTA BOOK OF THE YEAR AWARD WINNER LONGLISTED FOR THE 2017 MAN BOOKER PRIZE "A true leftfield wonder: Days Without End is a violent, superbly lyrical western offering a sweeping vision of America in the making."—Kazuo Ishiguro, Booker Prize winning author of The Remains of the Day and The Buried Giant From the two-time Man Booker Prize finalist Sebastian Barry, “a master storyteller” (Wall Street Journal), comes a powerful new novel of duty and family set against the American Indian and Civil Wars Thomas McNulty, aged barely seventeen and having fled the Great Famine in Ireland, signs up for the U.S. Army in the 1850s. With his brother in arms, John Cole, Thomas goes on to fight in the Indian Wars—against the Sioux and the Yurok—and, ultimately, the Civil War. Orphans of terrible hardships themselves, the men find these days to be vivid and alive, despite the horrors they see and are complicit in. Moving from the plains of Wyoming to Tennessee, Sebastian Barry’s latest work is a masterpiece of atmosphere and language. An intensely poignant story of two men and the makeshift family they create with a young Sioux girl, Winona, Days Without End is a fresh and haunting portrait of the most fateful years in American history and is a novel never to be forgotten.
Now we've lived together in contentment, more or less, for nigh on twenty year. Like turtle doves. - In prison, I mean, for fuck's sake, the chances of that.PJ and Christy: sworn enemies destined to share one small room for twenty years. As the two men recall the joys and torments of life outside - the childhood excursions, a deadly brawl, past loves and summer dresses - slowly they uncover the tragic events that have lead them to their cell in Montjoy. A play that explores our capacity to commit the deadliest of crimes but also our capacity for survival, reconciliation and love, ON BLUEBERRY HILL by Sebastian Barry (twice winner of the Costa Book of the Year) premiered in a Fishamble production at the Pavilion Theatre as part of the Dublin Theatre Festival and at the Centre Culturel Irlandais in Paris in October 2017.
Statistical analysis of shapes of 3D objects is an important problem with a wide range of applications. This analysis is difficult for many reasons, including the fact that objects differ in both geometry and topology. In this manuscript, we narrow the problem by focusing on objects with fixed topology, say objects that are diffeomorphic to unit spheres, and develop tools for analyzing their geometries. The main challenges in this problem are to register points across objects and to perform analysis while being invariant to certain shape-preserving transformations. We develop a comprehensive framework for analyzing shapes of spherical objects, i.e., objects that are embeddings of a unit sphere in ℝ, including tools for: quantifying shape differences, optimally deforming shapes into each other, summarizing shape samples, extracting principal modes of shape variability, and modeling shape variability associated with populations. An important strength of this framework is that it is elastic: it performs alignment, registration, and comparison in a single unified framework, while being invariant to shape-preserving transformations. The approach is essentially Riemannian in the following sense. We specify natural mathematical representations of surfaces of interest, and impose Riemannian metrics that are invariant to the actions of the shape-preserving transformations. In particular, they are invariant to reparameterizations of surfaces. While these metrics are too complicated to allow broad usage in practical applications, we introduce a novel representation, termed square-root normal fields (SRNFs), that transform a particular invariant elastic metric into the standard L2 metric. As a result, one can use standard techniques from functional data analysis for registering, comparing, and summarizing shapes. Specifically, this results in: pairwise registration of surfaces; computation of geodesic paths encoding optimal deformations; computation of Karcher means and covariances under the shape metric; tangent Principal Component Analysis (PCA) and extraction of dominant modes of variability; and finally, modeling of shape variability using wrapped normal densities. These ideas are demonstrated using two case studies: the analysis of surfaces denoting human bodies in terms of shape and pose variability; and the clustering and classification of the shapes of subcortical brain structures for use in medical diagnosis. This book develops these ideas without assuming advanced knowledge in differential geometry and statistics. We summarize some basic tools from differential geometry in the appendices, and introduce additional concepts and terminology as needed in the individual chapters.
