Leaning on advice
to save its rainforests from destruction. This idea was triggered by a very specific moral dilemma. The country’s largest oil find is located underneath the Yasuni National Park, home to a unique biodiversity and several Native American tribes living as huntergatherers in isolation. Oil companies are lobbying the government in Quito for licences to start drilling, which would of course mean dev...
متن کاملBuilding a Leaning Organization
CONTINUOUS IMPROVEMENT PROGRAMS are proliferating as corporations seek to better themselves and gain an edge. Unfortunately, however, failed programs far outnumber successes, and improvement rates remain low. That's because most companies have failed to grasp a basic truth. Before people and companies can improve, they first must learn. And to do this, they need to look beyond rhetoric and high...
متن کاملData Preprocessing for Supervised Leaning
Many factors affect the success of Machine Learning (ML) on a given task. The representation and quality of the instance data is first and foremost. If there is much irrelevant and redundant information present or noisy and unreliable data, then knowledge discovery during the training phase is more difficult. It is well known that data preparation and filtering steps take considerable amount of...
متن کاملLeft-leaning Red-Black Trees
The red-black tree model for implementing balanced search trees, introduced by Guibas and Sedgewick thirty years ago, is now found throughout our computational infrastructure. Red-black trees are described in standard textbooks and are the underlying data structure for symbol-table implementations within C++, Java, Python, BSD Unix, and many other modern systems. However, many of these implemen...
متن کاملValue Distribution for Eigenfunctions of Desymmetrized Quantum Maps
In the past few years,much attention has been devoted to the behavior of eigenfunctions of classically chaotic quantum systems. One aspect of this topic concerns their value distribution and specifically their extreme values (see [Be], [AS], [S1], [IS], [HeR], [ABST]). Our aim is to explore this topic for one of the best-studied models in quantum chaotic dynamics—the quantized cat map (see [HB]...
