Doctors in India Are Using AI to Combat Blindness

India is home to the world’s largest population of blind people and not nearly enough optometrists to provide the care the country needs. But recently, some doctors there have been receiving help in the fight against eye disease from an unexpected source. As Mashable reports, machine learning is being used to better understand the spread of blindness and predict the success rates of eye surgeries.

The initiative is part of a collaboration between Microsoft and the Indian not-for-profit LV Prasad Eye Institute (LVPEI). At the center of the project are their Azure machine learning and Power BI services: After analyzing the anonymous records of 1.1 million people, the AI system can trace patterns of eye disease. Doctors can then use projections of surgical outcomes for certain types of patients to make informed decisions on how to treat them.

On December 19, Microsoft announced partnerships with the Bascom Palmer Eye Institute at the University of Miami, the Flaum Eye Institute at the University of Rochester, the Federal University of Sao Paulo, and the Brien Holden Vision Institute in Australia. The company plans to continue working with eye doctors to examine new data and zero in on how to help blind children in particular, 200,000 to 700,000 of whom live in India.

Equipping doctors to treat visual impairments is just one of machine learning’s many potential medical applications. Earlier this year, researchers at Beth Israel Deaconess Medical Center and Harvard Medical School taught an AI system to detect breast cancer with near-human accuracy.

Why are the keys on a QWERTY keyboard laid out as they are?

C Stuart Hardwick:

What is commonly called QWERTY (more properly, the Sholes layout) was designed by Christopher Lathan Sholes, then modified through a series of business relationships. Sholes's original keyboard was alphabetical and modeled after a printing telegraph machine. The alphabetical layout was easy to learn, but not easy to type on.

For one thing, all practical typing machines of the day relied on mechanical levers, and adjacent letters could jam if struck with rapidity. There has long been a myth that Sholes designed the QWERTY layout to slow typists down in order to prevent this. Nothing could be further from the truth, but Sholes’s first customers were telegraphers. Over several years, he adapted the piano-like alphabetical keyboard into
a four-row keyboard designed to aid telegraphers in their transcription duties.

This new layout mostly spread out commonly struck keys, but also placed easily confused telegraph semaphores together. This layout was sufficient to permit telegraph transcription to keep up with transmissions and created a growing market.

During this time, Sholes teamed up with several other inventors to form a typewriter company with assignment of all related patents. An association with Remington led to increased sales, at which time another company acquired the shift platen patent that permits a typewriter to type in mixed case, and they seem to have made a few essentially random changes in order to avoid the original typewriter company patents.

So that’s it then, right? QWERTY is crap?

Well, no. QWERTY was based mostly on the needs of telegraphers in transcribing Morse code, and Morse had been scientifically designed to make transmission of English language messages as efficient as possible. The result is that the QWERTY arrangement is pretty good—efficiency-wise.

In the 1930s, John Dvorak used modern time-motion study techniques to design his own keyboard, and around it had grown up a whole cult following and mythology. But the fact is, it’s much ado about nothing. Careful scientific studies in the 1950s, '70s, and '80s have shown that choice between the Sholes and Dvorak layout makes no material difference in typing speed. Practice and effort are what yields rapid typing, and studies of professional typists have shown that however well we may perform on timed trials, few typists ever exceed 35 words per minute in their daily work.

So relax. Take an online typing course, practice a little, and relax.

Monthly Internet Costs in Every Country

Thanks to the internet, people around the world can conduct global research, trade tips, and find faraway friends without ever leaving their couch. Not everyone pays the same price for these digital privileges, though, according to new data visualizations spotted by Thrillist.

To compare internet user prices in each country, cost information site HowMuch.net created a series of maps. The data comes courtesy of English market research consultancy BDRC and Cable.co.uk, which teamed up to analyze 3351 broadband packages in 196 nations between August 18, 2017 and October 12, 2017.

In the U.S., for example, the average cost for internet service is $66 per month. That’s substantially more than what browsers pay in neighboring Mexico ($27) and Canada ($55). Still, we don’t have it bad compared to either Namibia or Burkina Faso, where users shell out a staggering $464 and $924, respectively, for monthly broadband access. In fact, internet in the U.S. is far cheaper than what residents in 113 countries pay, including those in Saudi Arabia ($84), Indonesia ($72), and Greenland ($84).

On average, internet costs in Asia and Russia tend to be among the lowest, while access is prohibitively expensive in sub-Saharan Africa and in certain parts of Oceania. As for the world’s cheapest internet, you’ll find it in Ukraine and Iran.
