We want to believe that serendipity brings us together, but is that just a myth? Mining the comedy of missed connections, THIS RANDOM WORLD asks the serious question of how often we travel parallel paths through the world without noticing. From an ailing woman who plans one final trip, to her daughter planning one great escape and her son falling prey to a prank gone wrong, this funny, intimate, and heartbreaking play explores the lives that may be happening just out of reach of our own.
Algorithmic Learning in a Random World by Vladimir Vovk,Alexander Gammerman,Glenn Shafer Pdf
This book is about conformal prediction, an approach to prediction that originated in machine learning in the late 1990s. The main feature of conformal prediction is the principled treatment of the reliability of predictions. The prediction algorithms described — conformal predictors — are provably valid in the sense that they evaluate the reliability of their own predictions in a way that is neither over-pessimistic nor over-optimistic (the latter being especially dangerous). The approach is still flexible enough to incorporate most of the existing powerful methods of machine learning. The book covers both key conformal predictors and the mathematical analysis of their properties. Algorithmic Learning in a Random World contains, in addition to proofs of validity, results about the efficiency of conformal predictors. The only assumption required for validity is that of "randomness" (the prediction algorithm is presented with independent and identically distributed examples); in later chapters, even the assumption of randomness is significantly relaxed. Interesting results about efficiency are established both under randomness and under stronger assumptions. Since publication of the First Edition in 2005 conformal prediction has found numerous applications in medicine and industry, and is becoming a popular machine-learning technique. This Second Edition contains three new chapters. One is about conformal predictive distributions, which are more informative than the set predictions produced by standard conformal predictors. Another is about the efficiency of ways of testing the assumption of randomness based on conformal prediction. The third new chapter harnesses conformal testing procedures for protecting machine-learning algorithms against changes in the distribution of the data. In addition, the existing chapters have been revised, updated, and expanded.
Algorithmic Learning in a Random World by Vladimir Vovk,Alexander Gammerman,Glenn Shafer Pdf
Algorithmic Learning in a Random World describes recent theoretical and experimental developments in building computable approximations to Kolmogorov's algorithmic notion of randomness. Based on these approximations, a new set of machine learning algorithms have been developed that can be used to make predictions and to estimate their confidence and credibility in high-dimensional spaces under the usual assumption that the data are independent and identically distributed (assumption of randomness). Another aim of this unique monograph is to outline some limits of predictions: The approach based on algorithmic theory of randomness allows for the proof of impossibility of prediction in certain situations. The book describes how several important machine learning problems, such as density estimation in high-dimensional spaces, cannot be solved if the only assumption is randomness.
"We are a people who matter." Inspired by President Barack Obama's Of Thee I Sing, Go Show the World is a tribute to historic and modern-day Indigenous heroes, featuring important figures such as Tecumseh, Sacagawea and former NASA astronaut John Herrington. Celebrating the stories of Indigenous people throughout time, Wab Kinew has created a powerful rap song, the lyrics of which are the basis for the text in this beautiful picture book, illustrated by the acclaimed Joe Morse. Including figures such as Crazy Horse, Net-no-kwa, former NASA astronaut John Herrington and Canadian NHL goalie Carey Price, Go Show the World showcases a diverse group of Indigenous people in the US and Canada, both the more well known and the not- so-widely recognized. Individually, their stories, though briefly touched on, are inspiring; collectively, they empower the reader with this message: "We are people who matter, yes, it's true; now let's show the world what people who matter can do."
*WINNER OF THE 2023 NATIONAL BUSINESS BOOK AWARD* *FINALIST FOR THE 2023 OTTAWA BOOK AWARD* *SHORTLISTED FOR THE SHAUGHNESSY COHEN PRIZE FOR POLITICAL WRITING* *SHORTLISTED FOR THE 2022 DONNER PRIZE* NATIONAL BESTSELLER From the former Governor of the Bank of Canada, a far-seeing guide to the powerful economic forces that will shape the decades ahead. The economic ground is shifting beneath our feet. The world is becoming more volatile, and people are understandably worried about their financial futures. In this urgent and accessible guide to the crises and opportunities that lie ahead, economist and former Governor of the Bank of Canada Stephen Poloz maps out the powerful tectonic forces that are shaping our future, and the ideas that will allow us to master them. These forces include an aging workforce, mounting debt, and rising income inequality. Technological advances, too, are adding to the pressure, putting people out of work, and climate change is forcing a transition to a lower-carbon economy. It is no surprise that people are feeling uncertain. The implications of these tectonic tensions will cascade throughout every dimension of our lives—the job market, the housing market, the investment climate, as well as government and central bank policy, and the role of the corporation within society. The pandemic has added momentum to many of them. Poloz skillfully argues that past crises, from the Victorian Depression in the late 1800s to the more recent downturn in 2008, give a hint of what is in store for us in the decades ahead. Unlike the purely destructive power of earthquakes, the upheaval that is sure to come in the decades ahead will offer unexpected opportunities for renewal and growth. Filled with takeaways for employers, investors, and policymakers, as well as families discussing jobs and mortgage renewals around the kitchen table, The Next Age of Uncertainty is an indispensable guide for those navigating the fault lines of the risky world ahead.
On Earth We're Briefly Gorgeous by Ocean Vuong Pdf
The instant New York Times Bestseller • Nominated for the 2019 National Book Award for Fiction “A lyrical work of self-discovery that’s shockingly intimate and insistently universal…Not so much briefly gorgeous as permanently stunning.” —Ron Charles, The Washington Post Ocean Vuong’s debut novel is a shattering portrait of a family, a first love, and the redemptive power of storytelling On Earth We’re Briefly Gorgeous is a letter from a son to a mother who cannot read. Written when the speaker, Little Dog, is in his late twenties, the letter unearths a family’s history that began before he was born — a history whose epicenter is rooted in Vietnam — and serves as a doorway into parts of his life his mother has never known, all of it leading to an unforgettable revelation. At once a witness to the fraught yet undeniable love between a single mother and her son, it is also a brutally honest exploration of race, class, and masculinity. Asking questions central to our American moment, immersed as we are in addiction, violence, and trauma, but undergirded by compassion and tenderness, On Earth We’re Briefly Gorgeous is as much about the power of telling one’s own story as it is about the obliterating silence of not being heard. With stunning urgency and grace, Ocean Vuong writes of people caught between disparate worlds, and asks how we heal and rescue one another without forsaking who we are. The question of how to survive, and how to make of it a kind of joy, powers the most important debut novel of many years.

NEW YORK TIMES BESTSELLER A “thrilling” (The New York Times), “dazzling” (The Wall Street Journal) tour of the radically different ways that animals perceive the world that will fill you with wonder and forever alter your perspective, by Pulitzer Prize–winning science journalist Ed Yong “One of this year’s finest works of narrative nonfiction.”—Oprah Daily ONE OF THE TEN BEST BOOKS OF THE YEAR: The Wall Street Journal, The New York Times, Time, People, The Philadelphia Inquirer, Slate, Reader’s Digest, Publishers Weekly, BookPage ONE OF THE BEST BOOKS OF THE YEAR: The Globe and Mail, The New Yorker, Oprah Daily, The Washington Post, The Guardian, Smithsonian Magazine, Kirkus Reviews, Library Journal The Earth teems with sights and textures, sounds and vibrations, smells and tastes, electric and magnetic fields. In An Immense World, Ed Yong coaxes us beyond the confines of our own senses to encounter beetles that are drawn to fires, turtles that can track the Earth’s magnetic fields, fish that fill rivers with electrical messages, and even humans who wield sonar like bats. We discover that a crocodile’s scaly face is as sensitive as a lover’s fingertips, that the eyes of a giant squid evolved to see sparkling whales, that plants thrum with the inaudible songs of courting bugs, and that even simple scallops have complex vision. We learn what bees see in flowers, what songbirds hear in their tunes, and what dogs smell on the street. We listen to stories of pivotal discoveries in the field, while looking ahead at the many mysteries that remain unsolved. Funny, rigorous, and suffused with the joy of discovery, An Immense World takes us on what Marcel Proust called “the only true voyage . . . not to visit strange lands, but to possess other eyes.”
The Nerviest Girl in the World by Melissa Wiley Pdf
A feisty girl from a family of ranchers lands a job as a daredevil stunt girl in the early days of silent film in this adventurous and funny cross between Wild Hearts Can't Be Broken and Ramona. Pearl lives on a ranch where her chores include collecting eggs and feeding ornery ostriches. She has three older brothers, who don't coddle her at all. And she knows a thing or two about horses, too. One day, Pearl's brothers get cushy jobs doing stunts for this new form of entertainment called "moving pictures." They're the Daredevil Donnelly Brothers, a Death-Defying Cowboy Trio. Before she knows it, Pearl has stumbled into being a stunt girl herself--and dreams of becoming a star. The only problem is, her mother has no idea what she's up to. And let's just say she wouldn't be too happy to find out that Pearl's been jumping out of burning buildings in her spare time. Filled with action, humor, and heart--not to mention those pesky ostriches--The Nerviest Girl in the World introduces a spunky heroine whose adventures will have kids on the edge of their seats and whose sense of humor will have them laughing until the very last line.
What are we not seeing? Our naked eyes see only a thin sliver of reality. We are blind in comparison to the X-rays that peer through skin, and the animals that can see in infrared or ultraviolet or with 360-degree vision. In The Reality Bubble, Ziya Tong illuminates this hidden world and takes us on a journey to examine ten of humanity’s biggest blind spots. What she reveals is not on the things we didn’t evolve to see but, more dangerously, the blindness of modern society. Fast-paced, utterly fascinating and deeply humane, this vitally important book gives voice to the sense we’ve all had – that there is more to the world than meets the eye.
