The Modern Data Nerd Isn’t as Nerdy as You Think | Enterprise | WIRED

The Modern Data Nerd Isn’t as Nerdy as You Think | Enterprise | WIRED | Researching | Scoop.it
Data scientists are fast becoming the rock stars of the 21st century. Thanks in part to Nate Silver's eerily accurate election predictions and Paul DePodesta's baseball-revolutionizing Moneyball techniques, math nerds have become celebrities. It's debatable how much their work differs from what statisticians have done for years, but it's a growing field, and many companies are desperate to hire their own data scientists. The irony is that many of these math nerds aren't as math nerdy as you might expect.
Tauren's insight:

Không cần phải thánh lắm về toán, thống kê... cũng có thể thành công được ở trong mảng khai phá dữ liệu.

"Data scientists are fast becoming the rock stars of the 21st century. Thanks in part to Nate Silver’s eerily accurate election predictions and Paul DePodesta’s baseball-revolutionizing Moneyball techniques, math nerds have become celebrities. It’s debatable how much their work differs from what statisticians have done for years, but it’s a growing field, and many companies are desperate to hire their own data scientists."

 

"Some of the best minds in the field lack the sort of heavy math or science training you might expect. Silver and Paul DePodesta have bachelor’s degrees in economics, but neither has a PhD. Former Facebook data scientist and Cloudera co-founder Jeff Hammerbacher — who helped define the field as it’s practiced today — only has a bachelor’s in mathematics. The top ranked competitor at Kaggle — which runs regular contest for data scientists — doesn’t have a PhD, and many of the site’s other elite competitors don’t either."

 

“In fact, I argue that often Ph.D.s in computer science in statistics spend too much time thinking about what algorithm to apply and not enough thinking about common sense issues like which set of variables (or features) are most likely to be important,” says Kaggle CEO Anthony Goldbloom."

 

"Some software vendors have used the perception that data science requires rare and expensive talent to pitch business intelligence applications that can be used by less technical employees to mine data. But while data analysts and business intelligence professionals tend to know what data sets to analyze and what to look for, data scientists are more experimental. They have to find data sets, figure out what to mine from them and how. Off the shelf software may simplify the mathematics, but there’s more to data science than crunching numbers."

Aviation milestone as Boeing delivers 747 number 1,500

Aviation milestone as Boeing delivers 747 number 1,500 | Researching | Scoop.it

It's the biggest milestone yet for the aircraft affectionately known as the "Queen of the Skies."

Tauren's insight:

Kỷ niệm 100 năm hàng không thương mại và chiếc Boeing 747 thứ 1500 được bán.

 

"It's the biggest milestone yet for the aircraft affectionately known as the "Queen of the Skies."


"After debuting in 1969 at the Paris Air Show, it opened up air travel to millions of passengers previously unable to afford taking to the skies."

Extreme Rainfall Is The New Normal, And We're Not Ready For It

Extreme Rainfall Is The New Normal, And We're Not Ready For It | Researching | Scoop.it
Heavy rains are flooding cities and towns from Nebraska to Michigan to Maine. Is the problem failing infrastructure, global warming...or both?
Tauren's insight:

Mỹ cũng ngập nặng sau mưa. Hệ quả của biến đổi khí hậu ngày càng thấy rõ

 

"Much of U.S. highway system was planned and built in the mid-20th century with historical rain and snow conditions in mind. Now these same systems are decades-old, under-maintained, and failing under the new normal we've created of extreme precipitation."


"By 9:30 am Wednesday, the system was moving over the New York City metro area. Long Island recorded 13.26 inches of rainfall in less than a day, according to the National Weather Service, breaking the New York state record set during Hurricane Irene in 2011. Severe roadway flooding trapped many drivers, and cut off parts of eastern Long Island from the rest of the state. "

Heads up for the gathering robot swarm

Heads up for the gathering robot swarm | Researching | Scoop.it

"Researchers build a 1000-strong swarm, which could lay the groundwork for robot construction crews or robot search-and-rescue parties

Tauren's insight:

Thí nghiệm quy mô lớn đầu tiên dùng 1000 robot để thử nghiên cứu về cách các tổ chức sinh học như kiến, chim hoặc cá có thể phát tín hiệu, di chuyển hoặc cùng làm một tác vụ nào đó mà ko cần đến một sự chỉ đạo tập trung nào. Robot trong thí nghiệm dùng cảm biến hồng ngoại (14$) để tự định vị và đo khoảng cách với con robot gần nhất, và chúng mất gần 10 tiếng di chuyển từng con một để xếp thành một hình đơn giản. Thế chưa thấm vào đâu so với các tổ chức sinh học, hàng ngàn con di chuyển sát cạnh nhau với tốc độ cao, chuyển hướng đột ngột nhưng ko hề có tai nạn xảy ra.

"As in a colony of ants, “there’s no centralized leader per se,” Rubenstein says. “Every robot is just talking to its neighbors and making its own decisions based on what it sees in its environment.”

 

1 cmt "In the week when we have heard of self repairing and self building robots, the thought of swarms of thousands of self powered robots, only leaves the question as to when DARPA 
or some other anti civilian organization gets hold of them for use against the people"

 

Swarming robots 'under control'? Then they don't undertsand swarms. Read "Prey" by Michael Crichton.
