AlphaZero--an Updated Model of AI

    Soon after Garry Kasparov, the former world chess champion, lost his rematch against IBM's Deep Blue in 1997, the short window of human-machine chess competition slammed shut forever. Unlike humans, machines keep getting faster, and today a smartphone chess app can be stronger than Deep Blue. However, as people see with the new AlphaZero system, machine dominance has not ended the historical role of chess as a laboratory of cognition.

    Much as airplanes don't flap their wings like birds, machines don't produce chess moves like humans do. Based on a generic algorithm (算法), AlphaZero incorporates deep learning and other AI techniques like Monte Carlo tree search to play against itself to develop its own chess knowledge. Unlike the traditional program Stockfish, which employs many preset evaluation functions as well as opening and endgame moves, AlphaZero starts out knowing only the rules of chess, with no preset human strategies. In a few hours, it plays more games against itself than have been recorded in human chess history. It teaches itself the best way to play, reevaluating the relative values of the pieces. It quickly becomes strong enough to win 28, draw 72, and lose none in a victory over Stockfish. Since AlphaZero can program itself, this superior understanding allows it to outclass the world's top traditional program despite calculating far fewer positions per second. It's the typical example of the cliché, "work smarter, not harder".

    AlphaZero shows that machines can be the experts, not merely expert tools. Explainability is still an issue—it's not going to put chess coaches out of business just yet. But the knowledge it produces is information humans can learn from. AlphaZero is surpassing humans in a profound and useful way, and researchers are working on transferring the knowledge acquired from AlphaZero to other fields.

    Machine learning systems aren't perfect. Even though great progresses have been achieved, AI algorithms are still struggling on open problems such as computer vision, natural language understanding... There will be cases where an AI will fail to detect exceptions to its rules. Therefore, as Kasparov writes, "We must work together to combine our strengths. I know better than most people what it's like to compete against a machine. Instead of raging against them, it's better if we're all on the same side."

(1)、Questions⑴①-⑴⑤: Judge if the following statements agree with the information given in the passage. Choose A for TRUE if the statements agree with it; choose B for FALSE if the statements don't agree with it; choose C for NOT GIVEN if the information the statements carry is not mentioned anywhere in the passage.根据文章内容判断下列表述。如果表述与文章内容一致,选A项;表述与文章内容不一致,选B项;文章中未提及的信息,则选C项。

②AlphaZero knows opening and endgame moves before playing.

③AlphaZero develops chess strategies by playing against itself.

④Chess coaches have already been laid off throughout the world.

    According to the recently published cultural mindset study from Culture Trip, 60% of people in the US and UK say that their outlook on life is shaped by influences from different cultures. At the same time, the economic landscape of the last decade has resulted in younger generations being more interested in collecting experiences than possessions.

    Welcome to the "new culture economy"

    The collision of the two trends—globalization and the experience economy—has caused a new travel concept with cultural curiosity at its heart. This is the "new culture economy". The phenomenon is having a profound impact on people's interactions and definitions of cultural exploration and presents an incredible commercial opportunity.

    Education, travel, exposure to other customs and the cultural mashup that energes are the more influential social effects of globalization. More than half of respondents from the cultural mindset study have friends living overseas, while 78% have friends or family of different nationalities. Besides, the confines of student debt and unaffordable housing have created a shift in spending patterns, and so a new set of values has emerged in which experiences matter more than ownership.

    Why we travel

    People's social networks expose them to digital influencers and keep them connected to friends or family living in other parts of the world. The combination of these cultural, social and personal drivers has helped us to identify four cultural mindsets.

    ⒈Culturally aware—The motivation to travel among this group is anchored in pleasure. They seek out familiarity and select destinations close to home or reflective of their own culture.

    ⒉Culturally curious—Those with this mindset travel to discover new things and disrupt their everyday routines. They seek some familiarity, but also want to explore boundaries. They want to be seen as someone who is interested in culture, but this is often expressed in terms of visual interest and well-known sites.

    ⒊Culturally immersive—For this group, travel is all about adventure and personal growth. They want to be seen as highly cultured and as "explorers"; they are happy to celebrate when things go wrong, which they see as the key ingredient to making memories.

    ⒋Culturally fluid—The group's identity is shaped by their familiarity with travel. They feel at home everywhere and have adopted a hybrid cultural identity. Memories are often tied to experiences with people that represent the culture they are travelling to rather than sites.

    The environmental trade-off

    The cultural mindset research also sheds light on how people perceive the effect of tourism on the environment and the measures they take to reduce their impact. Two in five millennials—more than any other generation—worry that tourism has a negative impact on the environment and over a third limit how much they travel to reduce their impact.

    While most people won't control their desire to travel entirely, good news is that those who see the world are also the ones taking measures in their everyday lives to reduce their impact on the environment.
