AlphaGo wrapped up victory for Google in the DeepMind Challenge Match by winning its third straight game against Go champion Lee Se-dol yesterday, but the 33-year-old South Korean has got at least some level of revenge — he's just defeated AlphaGo, the AI program developed by Google's DeepMind unit, in the fourth game of a five-game match in Seoul.

AlphaGo is now 3-1 up in the series with a professional record, if you can call it that, of 9-1 including the 5-0 win against European champion Fan Hui last year. Lee's first win came after an engrossing game where AlphaGo played some baffling moves, prompting commentators to wonder whether they were mistakes or — as we've often seen this week — just unusual strategies that would come good in the end despite the inscrutable approach. (To humans, at least.)

According to tweets from DeepMind founder Demis Hassabis, however, this time AlphaGo really did make mistakes. The AI "thought it was doing well, but got confused on move 87," Hassabis said, later clarifying that it made a mistake on move 79 but only realized its error by 87. AlphaGo adjusts its playing style based on its evaluation of how the game is progressing.

Lee entered the post-game press conference to rapturous applause, remarking "I've never been congratulated so much just because I won one game!" Lee referred back to his post-match prediction that he would win the series 5-0 or 4-1, saying that this one win feels even more valuable after losing the first three games.

"Lee Se-dol is an incredible player and he was too strong for AlphaGo today," said Hassabis, adding that the defeat would help DeepMind test the limits of its AI. "For us this loss is very valuable. We're not sure what happened yet."

Q1. In this video, there are 107 facts about "inside out ", which one you like most? Do you know any facts or funny details about movies?

It is almost Christmas and many of us are still scrambling around trying to choose the perfect gift for a friend or relative. What do they want? What do they need? What can we buy? We can spend hours in shops asking ourselves these questions. There is another way to select the perfect gift but it involves changing our perception of what gift giving is all about.

The problem is that we think about giving gifts as the exchange of physical objects. A useful alternative is to think of a gift as communication. When you give a gift to someone, what you are actually doing is speaking to them. You buy, make or discover a gift that says something to the receiver. They receive the gift, and if they are perceptive, they understand your message. Of course this is obvious, but somehow we forget it when we go to choose gifts. We focus first on the object or the need, then check what message it conveys.

You may have realised gifts are communication when someone gives you a gift and you are instantly aware of what it says. Some gifts communicate distance, others intimacy. Some say ” I love your creativity”, others “You should look after yourself”. Some are downright insulting. What gifts communicate is seldom attached to their price tag or their prestige. Some of the gifts that I have appreciated the most have been practically free for the giver to arrange for me, but have said so much that they have been immensely valuable.

If you harness this thinking, when you choose gifts, then you can quickly move towards the perfect gift. Ask yourself first, “What do I want to say to this person?” Then move on to “What can I give them that will communicate this?”. This is opposite to the more common “What can I buy them?” and then “What will they think of it?”.

This method could help you come up with some slightly off beat gifts, but at least they will be meaningful. One gift that I received recently was given as a result of this sort of thinking. My wife gave me a 1 day ticket of freedom. She took on all of my responsibilities for a day and sent me off to Tokyo to play. She wanted to say that she appreciated everything that I did, and that she understood that my responsibilities were sometimes a burden to me. That helped her to design the perfect gift which was simply a break from it all. I loved it.

That online review may recommend a restaurant in glowing prose, but should you eat up every word? Maybe not.

A months-long investigation by CBC’s Marketplace shows how easy it is for companies to deceive consumers online. It uncovered an entire industry designed to help businesses mislead consumers, bolstering companies’ online reputations with fake reviews and testimonials.

A good online reputation can have a huge impact on a company’s revenue. When researchers at the Harvard Business School analyzed restaurant reviews and revenue in Seattle, they found that a one-star increase on the popular review site Yelp meant a five to nine per cent increase in revenue for independent restaurants.

“Some data now show that a good majority of people in North America believe and trust online reviews more than they trust their friends’ opinions,” Jeff Hancock, a professor who researches online deception at Cornell University in Ithaca, NY, told Marketplace co-host Erica Johnson.

The movement calls for accountability through all steps in the clothes-making process.

On April 24, 2013, a garment factory collapsed at Rana Plaza in Bangladesh. The incident led to the death of 1,129 workers — a tragedy that revealed the ugly truth behind the clothes on almost everyone’s backs: it’s very likely they were made in sweatshops like this.

Not enough has changed in the two years since that incident, according to a Human Rights Watch report released Wednesday titled “Whoever Raises their Head Suffers the Most.”

The demand for an ever-replenishing supply of cheap “fast fashion” has been a race to the bottom, in which factories outsource to the lowest bidders, resulting in human rights violations for the workers and unregulated pollution of the environment. In fact, fashion is the second-highest polluting industry behind oil. But it isn’t just the lowest-end clothing: companies such as H&M, Victoria’s Secret, Nike, The Gap and Marks & Spencer have had scandalsinvolving working conditions in these shadow factories.
