Computers have beaten human world champions at chess and, earlier this year, the board game Go. So far, though, they have struggled at the card table. So we challenged one AI to a game.

    Why is poker(扑克) so difficult? Chess and Go are “information complete” games where all players can see all the relevant information. In poker, other players' cards are hidden, making it an “information incomplete” game. Players have to guess opponents' hands from their actions—tricky for computers. Poker has become a new benchmark for AI research. Solving poker could lead to many breakthroughs, from cyber security to driverless cars.

    Scientists believe it is only a matter of time before AI once again vanquishes humans, hence our human-machine match comes up in a game of Texas Hold's Em Limit Poker. The AI was developed by Johannes Heinrich, researcher studying machine learning at UCL. It combines two techniques: neural(神经的) networks and reinforcement learning(强化学习).

    Neural networks, to some degree, copy the structure of human brains: their processors are highly interconnected and work at the same time to solve problems. They are good at spotting patterns in huge amounts of data. Reinforcement learning is when a machine, given a task, carries it out, learning from mistakes it makes. In this case, it means playing poker against itself billions of times to get better.

    Mr Heinrich told Sky News: “Today we are presenting a new procedure that has learned in a different way, more similar to how humans learn. In particular, it is able to learn abstract patterns, represented by its neural network, which allow it to deal with new and unseen situations.”

    After two hours of quite defensive play, from the computer at least, we called it a draw.

    I could feel the judging eyes of my family burning a hole into the back of my head as I picked up my phone. All of a sudden, the chattering in the living room died and all I could hear was the sound of the turkey sizzling (发出嘶嘶声) in the oven.

    “Look at her! She's been on her phone all day long! It's all your fault! Children will never respect elders if they are not taught how to behave! ” my grandmother shouted.

    I was very shocked and angry! I opened my mouth to say something, but words failed me and I just sat down quietly on the chair like a mouse in its trap. I thought “Here we go again.” I truly love my family and I would do anything for them. I also know that they would do anything for me as well. However, there are moments that make me feel that they are just stuck with me. They all agree on one thing: technology is wrecking me.

    If I am going to be treated like a child or completely ignored, I will most likely not enjoy your company, and I feel that this applies to (适用于) the majority of the people. So I sometimes simply shut myself in my room and listened to the voices coming from the living room, thinking: They all grew up in a world so different that it amazes me how they have actually gotten this far. They did not have phones or any type of advanced technology, which is both good and bad. Bad because they had almost no type of fast communication, and good because they were forced to interact (互动) with one another, which is something today's society is lacking in. However, maybe if they made an effort to be aware of how things work nowadays, they would not be so against everything.

    Listed below are the stories of women you may not know about, but definitely should.

    Hedy Lamarr

    Hedy Lamarr starred in many films. But her film career is far from her only noteworthy achievement; she was also a brilliant inventor. In 1942, she and composer George Antheil received a patent（专利）for a device that could change radio signal frequencies. The purpose of the technology was to keep military enemies from figuring out messages. But it did more than that - it laid a foundation for the wireless technology we use today.

    Maria Sibylla Merian

    Today, children can happily explain how a caterpillar（毛虫） tums into a butterfly. But there was a time when no one knew this. Until the 1670s, scientists thought that caterpillars and butterflies were two totally different creatures. Thanks to Maria, we know the truth about these beautiful winged insects. Fascinated by insects, she began collecting, studying and drawing them as a child. It was through her study of caterpillars that she discovered the truth about their life cycles. She published two volumes of naturalist research, which provide major contributions to the field of entomology（昆虫学）.

    Ada Lovelace

    Ada Lovelace, the daughter of celebrated British poet Lord Byron, wasn't a poet herself but the world's first computer programmer. We think of computers as a recent invention, but people were toying with the idea of "computing machines" in the mid – 19th century when Lovelace was alive. Lovelace's mathematical genius was apparent at a young age and caught the attention of Cambridge professor Charles Babbage, who was working to design early computing machines that would be able to quickly solve math problems. Lovelace wrote some suggestions as to how to program the machines to work out numbers.

    In addition to designing this early computer program, she was also the first to surest that these computers might be able to do more than compute. She imagined them doing almost everything, from producing images to composing music.

    I love our kitchen. It's one of the most used parts of our home. About 9 years ago we updated our kitchen and got all new collections. At the time I didn't really do a lot of research on the functions of the equipment and I really wish I had. There were so many different choices on the market and I ended up buying some that I didn't really like all that much and now that it's time to update them again, I'll be more careful with the ones I choose.

    I've had my eye on KitchenAid for a while, especially the new KitchenAid equipment at BestBuy. The new KitchenAid equipment at Best Buy has a cook-like quality without the premium price that you might expect to pay, so it won't cost you a fortune.

    Most heroes are not super. They don't appear in comic books, on television, or in movies. They just do what they believe needs to be done to make their world a better place. Bike Batman is one of them.

    Bike Batman is a 30-year-old married engineer who lives in Seattle, Washington. He's a cyclist who also buys and sells bikes as a hobby.

    About three years ago, he was looking for a bike for his wife. He found one on Craigslist, a website where people list things they want to sell. As he often does, he also looked at Bike Index, a popular website that allows users to register their bikes and post reports when they're taken. The bike, which he was considering purchasing, clearly matched one reported stolen on Bike Index. Then he called the person who claimed to be the bike's owner and arranged to meet him-- supposedly to complete the sale. When the two men met, Bike Batman told the thief, "You've got two options. You can wait until a police officer gets here, or you can just get out of here." You can imagine what the thief did.

    After that first success, Bike Batman developed a safer routine. When he sees questionable bike ads on Craigslist, he cross-references the image with bikes reported on Bike Index. Once he has confirmed it with the owner, he arranges a meet-up with the thief and will call the Seattle police department so that officers can participate in the action. In more than half of the 22 cases in which he has got back and returned bikes, the thieves have been arrested. In one case, Bike Batman even helped a family recover a wide range of prized possessions that suspects had stolen during a home burglary.

    His nickname came from a discussion with a police officer who suggested he be called "Robin Hood". Since he wasn't exactly stealing from the rich and giving to the poor, "Batman" seemed a better fit. The idea of a superhero punishing criminals feels pretty silly to him, but the main reason he continues his work is to keep up Seattle's reputation as a friendly city.
