U.S. Relations With Cuba

U.S.-CUBA RELATIONS

At the height of the Cold War, and following the Cuban government's expropriation of U.S. properties and its move toward adoption of a one-party system of government, the United States imposed an embargo on Cuba in 1960 and broke diplomatic relations in 1961. On December 17, 2014, President Obama announced a new chapter in U.S.-Cuba relations. A major step in this process was reached on July 1, 2015, when President Obama announced the decision to re-establish diplomatic relations between the United States and Cuba, effective July 20 with the re-opening of embassies in both countries. President Obama’s trip to Cuba in March 2016 marked a historic milestone in the normalization process between the United States and Cuba.

U.S. policy toward Cuba is focused on supporting our values, such as freedom of speech and assembly and the ability to access information, through engagement. The U.S. government is reaching out to the Cuban people by fostering increased people-to-people exchanges, encouraging the development of telecommunications and the internet, and creating opportunities for U.S. businesses to support the growth of Cuba’s nascent private sector. Through the opening of embassies, the United States is now able to engage more broadly across all sectors of Cuban society, including the government, civil society, and the general public. The United States is committed to supporting safe, orderly, and legal migration from Cuba through the effective implementation of the 1994-95 U.S.-Cuba Migration Accords.

How Google's AlphaGo Beat a Go World Champion

On March 19, 2016, the strongest Go player in the world, Lee Sedol, sits down for a game against Google DeepMind’s artificial-intelligence program, AlphaGo. They’re at the Four Seasons Hotel in Seoul’s Gwanghwamun district, and it’s a big deal: Most major South Korean television networks are carrying the game. In China, 60 million people are tuning in. For the English-speaking world, the American Go Association and DeepMind are running an English-language livestream on YouTube, and 100,000 people are watching. A few hundred members of the press are in adjacent rooms, watching the game alongside expert commentators.

The game room itself is spare: a table, two black leather chairs, some cameras. Three officials presiding over the match sit in the back. Across from Lee sits Aja Huang, one of AlphaGo’s lead programmers; and beside him is a computer monitor that displays AlphaGo’s move choices. Huang’s job is to physically place AlphaGo’s pieces on the board. AlphaGo itself is not any one machine—it’s a piece of distributed software supported by a team of more than 100 scientists.


Tonight, Lee Sedol is supported by one 33-year-old human brain and approximately 12 ounces of coffee.

Most people are betting on Lee to win.

At its core, the game of Go, which originated in China more than 2,500 years ago, is an abstract war simulation. Players start with a completely blank board and place black and white stones, one at a time, to surround territory. Once placed, stones do not move, and they’re removed only if they’re “killed”—that is, surrounded completely by the opponent’s stones. And so the game goes—black stone, white stone, black stone, white stone—until the board is covered in an intricate tapestry of black and white.

The rules of Go are simple and take only a few minutes to learn, but the possibilities are seemingly endless. The number of potential legal board positions is:

208,168,199,381,979,984,699,478,633,344,862,770,286,522,

453,884,530,548,425,639,456,820,927,419,612,738,015,378,

525,648,451,698,519,643,907,259,916,015,628,128,546,089,

888,314,427, 129,715,319,317,557,736,620,397,247,064,840,

935.



That number—which is greater than the number of atoms in the universe—was only determined in early 2016. Because there are so many directions any given game can move in, Go is a notoriously difficult game for computers to play. It has often been called the “Holy Grail” of artificial intelligence.
