Rules for building formal models that use fast-and-frugal heuristics, extending the psychological study of classification to the real world of uncertainty. This book focuses on classification--allocating objects into categories--"in the wild," in real-world situations and far from the certainty of the lab. In the wild, unlike in typical psychological experiments, the future is not knowable and uncertainty cannot be meaningfully reduced to probability. Connecting the science of heuristics with machine learning, the book shows how to create formal models using classification rules that are simple, fast, and transparent and that can be as accurate as mathematically sophisticated algorithms developed for machine learning.
The olive is one of the oldest type of fruit trees in the Mediterranean area and was one of the first species to be cultivated. However, despite its long history, there are still many aspects of its development that have not been sufficiently explored, and these include the distribution of the species and its taxonomy. This publication reviews its origin and classification, in order to provide a foundation for further research about this plant.
NATIONAL BESTSELLER • In April 1992 a young man from a well-to-do family hitchhiked to Alaska and walked alone into the wilderness north of Mt. McKinley. Four months later, his decomposed body was found by a moose hunter. This is the unforgettable story of how Christopher Johnson McCandless came to die. "It may be nonfiction, but Into the Wild is a mystery of the highest order." —Entertainment Weekly McCandess had given $25,000 in savings to charity, abandoned his car and most of his possessions, burned all the cash in his wallet, and invented a new life for himself. Not long after, he was dead. Into the Wild is the mesmerizing, heartbreaking tale of an enigmatic young man who goes missing in the wild and whose story captured the world’s attention. Immediately after graduating from college in 1991, McCandless had roamed through the West and Southwest on a vision quest like those made by his heroes Jack London and John Muir. In the Mojave Desert he abandoned his car, stripped it of its license plates, and burned all of his cash. He would give himself a new name, Alexander Supertramp, and, unencumbered by money and belongings, he would be free to wallow in the raw, unfiltered experiences that nature presented. Craving a blank spot on the map, McCandless simply threw the maps away. Leaving behind his desperate parents and sister, he vanished into the wild. Jon Krakauer constructs a clarifying prism through which he reassembles the disquieting facts of McCandless's short life. Admitting an interest that borders on obsession, he searches for the clues to the drives and desires that propelled McCandless. When McCandless's innocent mistakes turn out to be irreversible and fatal, he becomes the stuff of tabloid headlines and is dismissed for his naiveté, pretensions, and hubris. He is said to have had a death wish but wanting to die is a very different thing from being compelled to look over the edge. Krakauer brings McCandless's uncompromising pilgrimage out of the shadows, and the peril, adversity, and renunciation sought by this enigmatic young man are illuminated with a rare understanding—and not an ounce of sentimentality. Into the Wild is a tour de force. The power and luminosity of Jon Krakauer's stoytelling blaze through every page.
