Сложное поведение кибернетических систем складывается из цепочек «распознавание ситуации — принятие решения — действие». Книга посвящена первому из этих звеньев. В популярной форме излагается подход к распознаванию, основанный на построении «модели мира» — логического пространства взаимосвязанных признаков и разделения процесса распознавания на два этапа: индуктивный и дедуктивный.

This will be a detailed 'biography' of ducks and geese that breed in or regularly visit the UK – covering 30 species in all. It will include chapters on the evolution of ducks and geese, their place in the natural world, their anatomy and physiology, various feeding methods, spectacular courtship displays and diverse breeding behaviour. Marianne Taylor will reveal their often epic migrations and examine their social interactions with their own and other species, including their unusual readiness to hybridise. She will also detail their relationships with humankind over the centuries, including their presence in folklore and literature and their role in our lives as both prey and pets.

People all over Britain and Europe have long welcomed the arrival of swifts and swallows as a promise of summer being just around the corner. And with their similar long wings and dashing flight, it is perhaps understandable that we often confuse the two birds. After all, they have much in common: both feed on flying insects, both breed around buildings, and both are long-distance migrants that spend winter in Africa. But appearances can be deceptive. Swifts and swallows are completely unrelated birds that have adapted through evolution to survive in similar ways. In Spotlight: Swifts and Swallows, Mike Unwin reveals their fascinating lifestyles, explains how and why they have acquired their similarities, and ways in which we can help protect them.

Eagles are among the most impressive hunters of the animal world. Their predatory prowess and flying skills have imbued them with a romance and mystique that runs deep in our culture and has elevated them to emblems of freedom and power across the globe. At the same time, however, people have long seen eagles as competitors. Reviled by farmers and gamekeepers as snatchers of livestock, many species have been driven into decline by persecution and disturbance. Two species of eagle occur in Britain - among 60 worldwide - and are the focus of this book. The regal Golden Eagle is the definitive 'true' eagle and occurs in wilderness areas across the northern hemisphere; the even larger White-tailed Eagle, reintroduced to the UK after historic extinction, belongs to the separate 'sea eagles' genus.

Hero or villain? Few animals divide opinion like the Red Fox. This most successful of the world's wild canids has lived alongside people from time immemorial. Celebrated by some for its resourcefulness and lush pelt, reviled by others for plundering chicken runs and overturning bins, it has worked its way deep into Western. Behind the folklore and tabloid headlines, however, lies a remarkable natural history success story. In Spotlight: Foxes Mike Unwin explores how the Red Fox's versatility has allowed it to thrive across the northern hemisphere, from desert and mountain to farmland and urban jungle. This informative ebook covers all aspects of the Red Fox biology and lifestyle, including hunting and caching food, defending a territory, raising a litter and understanding the secrets of its complex vocalisations and body language. Finally, he examines the complex, often troubled relationship that the Fox has enjoyed and both endured with humankind, and suggests what the future might hold.

Snakes are superbly secretive reptiles, celebrated by many for their highly tuned senses and their complex and mysterious seasonal behaviours. Though some people may be fearful of them, these important reptiles play a crucial role in many habitats. And an encounter with any one of our native snake species is an experience worth cherishing. In Spotlight Snakes, Jules Howard takes readers on a journey through the ecology and lifestyle of Britain's three native snake species: the Barred Grass Snake, the Smooth Snake and our only venomous snake species, the Adder. As well as uncovering their unique hunting styles and courtship rituals, he delves into the myths and legends at the heart of humankind's widespread and sometimes troublesome fascination with these animals. He also charts the conservation challenges our native snakes face in the modern age and explores the solutions conservationists are employing to help these extraordinary predators remain a vital part of British ecosystems for generations to come.

Seals are the sleekest and most agile of all marine mammals, and they are superbly adapted to the watery world in which they spend most of their time. With their whiskery dog-like faces, curious nature and vulnerable pups, they are enduringly appealing animals. Although air-breathing, seals are superbly tuned to hunt, sleep, mate and keep warm while out at sea, but they remain inextricably linked to land. In Spotlight Seals, Frances Dipper explores the intricate lives of the UK's native Grey and Common Seals and their amazing physical and behavioural adaptations to a life split between land and sea. She reveals the complex physiology that allows seals to dive deep and for long periods without coming to any harm. Once exploited for their meat and skins, seals now have protection around the British Isles. Their numbers are increasing, but they still face the danger of plastic litter in their environment. Dipper also explores age-old legends, interactions between humans and seals, and the best places to watch them in the UK.
