Dataset Shift in Machine Learning
Dataset shift is a common problem in predictive modeling that occurs when the joint distribution of inputs and outputs differs between training and test stages. Covariate shift, a particular case of dataset shift, occurs when only the input distribution changes. Dataset shift is present in most practical applications, for reasons ranging from the bias introduced by experimental design to the irreproducibility of the testing conditions at training time. (An example is -email spam filtering, which may fail to recognize spam that differs in form from the spam the automatic filter has been built on.) Despite this, and despite the attention given to the apparently similar problems of semi-supervised learning and active learning, dataset shift has received relatively little attention in the machine learning community until recently. This volume offers an overview of current efforts to deal with dataset and covariate shift.

Secrets of Pawnless Endings
Endings without pawns occur frequently, yet even Grandmasters often fail to handle them accurately. Aided by a computer database, the author explains the underlying ideas and provides the definitive truth about the most important endgames without pawns.

The Emergent Multiverse
The Emergent Multiverse presents a striking new account of the ‘many worlds’ approach to quantum theory. The point of science, it is generally accepted, is to tell us how the world works and what it is like. But quantum theory seems to fail to do this: taken literally as a theory of the world, it seems to make crazy claims: particles are in two places at once; cats are alive and dead at the same time. So physicists and philosophers have often been led either to give up on the idea that quantum theory describes reality, or to modify or augment the theory. The Everett interpretation of quantum mechanics takes the apparent craziness seriously, and asks, ‘what would it be like if particles really were in two places at once, if cats really were alive and dead at the same time’? The answer, it turns out, is that if the world were like thatif it were as quantum theory claimsit would be a world that, at the macroscopic level, was constantly branching into copieshence the more sensationalist name for the Everett interpretation, the ‘many worlds theory’. But really, the interpretation is not sensationalist at all: it simply takes quantum theory seriously, literally, as a description of the world. Once dismissed as absurd, it is now accepted by many physicists as the best way to make coherent sense of quantum theory. David Wallace offers a clear and up-to-date survey of work on the Everett interpretation in physics and in philosophy of science, and at the same time provides a self-contained and thoroughly modern account of itan account which is accessible to readers who have previously studied quantum theory at undergraduate level, and which will shape the future direction of research by leading experts in the field.

Language Lateralization and Psychosis
In 1861 Paul Broca discovered that, in most individuals, the left hemisphere of the brain is dominant for language. Taking language as an example, the first part of this book explains the normal development of bodily asymmetry and lateralization, its association with hand preference, genetic aspects, geographical differences and the influence of gender. The coverage then moves on to review the association between language lateralization and psychosis, describing findings in patients with schizophrenia to suggest the dominant hemisphere may fail to completely inhibit the language areas in the non-dominant half. The language allowed to ‘release’ from the right hemisphere can lead to psychotic symptoms including auditory verbal hallucinations and formal thought disorder. This book should be read by psychiatrists, neurologists and neuroscientists working in the field of psychosis and other brain scientists interested in laterality.
