Learning, Fast and Deep

    Over the past five years researchers in artificial intelligence have become the rock stars of the technology world. A branch of AI known as deep learning, which uses neural(神经的) networks to scan through large volumes of data looking for patterns, has proven so useful that skilled practitioners can command high six-figure salaries to build software for Amazon, Apple, Facebook and Google.

    The standard route into these jobs has been a PhD in computer science from one of America's top universities. Earning one takes years and requires a personality suited to academia, which is rare among more normal folk.

    That is changing.

    Last month fast.ai, a non-profit education organization based in San Francisco, kicked off the third year of its course in deep learning. Since its foundation it has attracted more than 100, 000 students around the globe from India to Nigeria. The course and others like it, come with a simple idea: there is no need to spend years obtaining a PhD in order to practise deep learning. Creating software that learns can be taught as a craft, not as a high intellectual pursuit to be undertaken only in an ivory tower. Fast. ai's course can be completed in just seven weeks.

    To make it accessible to anyone who wants to learn how to build AI software is the aim of Jeremy Howard, who founded fast.ai with Rachel Thomas, a mathematician. He says school mathematics is sufficient. "No. Greek. Letters," Mr. Howard intones, pounding the table with his fist for punctuation.

    Some experts worry that this will serve only to create a flood of unreliable AI systems which will be useless at best and dangerous at worst. In the earliest days of the Internet, only a select few nerds, namely computer holies with specific skills, could build applications. Not many people used them. Then the invention of the World Wide Web led to an explosion of web pages, both good and bad. But it was only by opening up to all that the Internet gave birth to online shopping, instant global communications and search. If Mr. Howard and others have their way, making the development of AI software easier will bring forth a new crop of fruit of a different kind.

(1)、What can we learn about deep learning?
A、It replaces artificial intelligence. B、It attracts rock stars to practice. C、It scans patterns for large companies. D、It helps technicians to create software.
(2)、Fast. ai is an organization that         .

(4)、It can be inferred from the last paragraph that     .
A、it is quite reliable for anyone to grasp artificial intelligence B、the Internet has brought forth a flood of useless AI systems C、opening up to all leads to instant global search and online shopping D、simplifying software development may result in unexpected outcomes

Your 2018 Reading List, Provided by Bill Gates

    Most of us can't live like billionaire Microsoft co-founder Bill Gates, but we can read like him. Gates recommended four books in 2018—though some were published earlier.

    Leonardo da Vinci, by Walter Isaacson (2017)

    The bestselling biographer of Steve Jobs and Albert Einstein researched deeply into da Vinci's contributions beyond art, highlighting the breadth of his scientific, technological, and creative output. “Leonardo nearly understood almost all of what was known on the planet at the time. That's mostly because of his curiosity about every area of natural science and the human experience,” said Gates.

    The Best We Could Do: An Illustrated Memoir, by Thi Bui (2017)

    Gates calls this graphic novel “really impressive”. Bui is the daughter of Vietnamese refugees who came to America after the fall of Saigon, and becoming a parent inspired her to look into her own parents' miserable history. “I was struck by how the experiences Bui illustrates manage to be both universal and specific to their circumstances,” said Gates.

    Lincoln in the Bardo, by George Saunders (2018)

    Saunders, a long-time short story writer, won high praise for this novel. The book imagines the ghosts that haunt (萦绕) the basement of Willie Lincoln, Abraham Lincoln's son, who died at 11 in real life. “Willie's death after the Civil War made the president have a new understanding of the grief he's creating in other families by sending their sons off to die in battle,” said Gates.

Origin Story: A Big History of Everything, by David Christian (2018)

    This new book is by the creator of Big History, a free, online social studies course. It traces history in wide, sweeping movements, starting with the Big Bang, and it provides, in effect, a short course in modern science. This is a brief history of the universe. “David gets a little stuck on the current economic and political problems in the West, and I wish he talked more about the role innovation will play in preventing the worst effects of climate change,” said Gates.

    Water is a necessity of life. Rain, especially, helps plants grow and stay green. But too much rain, especially in cities, can lead to flooding. That can cause waste water systems to overflow and send pollutants into rivers and other waterways. To fight the problem, several cities in the United States are starting programs like rooftop gardens.

    A team at the University of the District of Columbia in the nation's capital has created a garden on the top of one school building. The garden holds many kinds of plants to help absorb rainwater and grow food at the same time. Architect David Bell has designed five "green roofs" for the university. He says he is excited about the project because "it meant doing something more than just dealing with storm water management. It took advantage of a resource above the city and these flat roofs that aren't doing anything really became something that was about urban agriculture." Rainwater is collected in large containers and sent through a system that waters the rooftop garden. The roof is filled with green life that appeals to insects.

    In cities, "you don't have that many spaces to choose from and so rooftops are just (unused) space," says Caitlin Arlotta. She is a student in the school's Urban Agriculture program. The project is part of a research program to see which plants do well on rooftops. The researchers are looking at plants including strawberries, tomatoes and sweet potatoes. The university also has other green spaces. "We also have our own farm experiments," Arlotta said. "Within each of those growing systems, we want to be able to tell people which sorts of these crops grow the best."

    Sandy Farber Bandier helps run UDC's Master Gardener program. It seeks to improve cities and make them beautiful by training people to become Master Gardeners. She says she's been surprised by the garden's output. "My biggest surprise was that we produced 4, 250 pounds of produce the first year and was able to spread that to people in need." She also likes being able to show people who live in D. C. and others beyond the nation's capital what and how food can be grown on a rooftop. "This is the future for food. You grow it here, you prepare it in a commercial kitchen, you distribute through farmers markets, food trucks, and then you recycle."

    Dreaming of summer picnics filled with family and fun? We've come up with 4 of the top picnic areas across the US.

    Cumberland Islands, Georgia

    Just a few hours south of Savannah, this national seashore is a wonderful picnic place. It's an unspoiled place in the Deep South with over 50 miles of hiking trails (小径). Covered in Spanish moss, the trails are lined with trees and since it's still a rural area, the stars line up for a grand show at night and create the perfect evening starlit picnic opportunity.

    Grant Park, Chicago

    If you are looking for delicious food in Chicago, go for a taste of a 20-day, lake-front, foodie festival that happens in October each year. Grab a spot near the fountain to enjoy your picnic, appreciate the city scenery and lake views and relax with family and friends. If you are there on July 4th, be sure to plan the day to include the fireworks display at the Navy Pier.

    Cranberry Islands, Maine

    Here, you'll enjoy natural picnics with island views. The islands are a delightful group of islands about 20 minutes offshore from Acadia National Park. You can visit the islands by private boat or ferry service. Bring a picnic basket along for the ride as it's a romantic picnic area to take your special someone or go for a family outing to visit the islands.

    Big Sur, California

    The Point Lobos State Reserve is a small gem. Besides the coastal wildlife there are rare plant communities, and unique geological formations. It's good to have a picnic there. We recommend bringing a telescope, because much of the wildlife can be seen only at a distance.
