Baidu Forced To Withdraw Last Month's ImageNet Test Results

elwinc writes: Back in mid-May, Baidu, a computer research and services organization in Mainland China, announced impressive results on the ImageNet "Large Scale Visual Recognition Challenge," besting results posted by Google and Microsoft. Turns out, Baidu gamed the system, creating 30 accounts and running far more than the 2 tests per week allowed in the contest. Having been caught cheating, Baidu has been banned for a year from the challenge. I believe all competitors are using variations on the convolutional neural network, AKA deep network. Running the test dozens of times per week might allow a competitor to pre-tune parameters for the particular problem, thus producing results that might not generalize to other problems. All of which makes it quite ironic that a Baidu scientist crowed "Our company is now leading the race in computer intelligence!"

      I'm not surprised, but not for the reason I suspect you have in mind: "Because Chinese are just so and so...".

      However, it does not really surprise me that we see this from some Chinese companies. China is a developing nation, and they are still relatively new to the way companies play it in the West - not that we are in fact more honest in the West, we have just learned how and when to be dishonest in a way that doesn't make as much noise. I mean, just think of large corporations that avoid paying tax or buy cheaply from sweat-shops employing child-labour. There is no shortage of examples.

      But there is another thing in it: lack of regulation. It should not be a surprise to anyone that when there is too little regulation, the most ruthless will feel entitled to bully others - the free, unregulated market can never work to the benefit of everybody, because there will always some, that ruthlessly go for maximising their own short-term advantage, and and that behaviour pushes out the competition and creates monopolies. It is perhaps ironical that this argument is exactly analogous with the argument against Communism: "people are selfish, so if they don't have a reason to work harder, most won't".

      We see this in all developing countries, but perhaps most tragilcally in Russia, where they tried to go from tightly regulated Communism to a kind of laissez-faire Capitalism overnight and got horribly burned. And they ended up with the same kind of masters as before, because scum always rises to the top of the pond.

      All companies have these kind of skeletons in the closet. Chinese companies simply seem to have some more on top of those which everyone else lovingly owns.
      Lack of regulation might be a reason when seeing this internally (within the country) - and then again, when all else is equal... But here we're talking about international events, and that's where you see companies A, B, C playing by the rules and company D (Chinese, more often than not) trying to cheat its way in.
      No more than a couple weeks ago there was a story here on /. about Chinese students taking exams instead of the ones who should. After many, many, MANY such stories over the years one can't help but develop a stereotype.
      From fake $ITEM to cheating in competitions, China seems on top of the world as count of occurrences.

      I googled "chinese cheating": got 22.6M results, top results are about exam cheating.
      I also googled "americans cheating", got 14.8M results, top results are about marital cheating.

    This reminds me of some Chinese ball screws (rotary to linear motion components) my company once ordered from Alibaba. The companies had pictures, drawings and put together quotes for parts but then delivered samples that were just totally totally useless. Some of these 'precision' parts looked like they had been made with a file. It just didn't make any sense that they would waste their and our time on such clearly incompetent products.

    But when you go there you realise the problem. It is basically an economy in a state of hyper competition. There is so much competition that people will just try anything get ahead, completely oblivious to the wider problem or goal they are trying to solve. You can see that in how the government had to rationalise the solar industry because nobody could make any money. They are just really really crazy competitive.

    The trouble though is that there are now many good Chinese engineers who know what they are doing but are still hyper competitive. I really don't know how us westerners with our 40hr work weeks, healthcare and pensions are going to eventually compete with that until we too are faced with the desperation of trying to escape from abject poverty along with 1 billion other people.

    People growing up under oppressive governments have much fewer problems with cheating — because cheating government is a fair game. It rubs off — and the attitude is quickly extended to non-governmental institutions large and even smaller ones.

    This is not "racism" — ex-Soviets like myself often have the same problem... A cheating Western student fears (or used to fear) the shame of being exposed. A Chinese — or a Soviet — fears merely getting caught. Like a speeding ticket — there is no shame in driving fast, only in being stopped by "the bear".

    China today uses drones to catch cheaters — America had not felt the need for such measures. Perhaps, it was a foolish attitude, because we the immigrants bring all our traits to the "wonderful tapestry of diversity", not just the good ones...

      Yes, well.. Truth be told, cheating and being dishonest are usually not long term strategies for success under any system. You cheat in school? You will pay later when the next course comes along that uses the material you don't know. Cheat again and you just increase your chances of getting caught. One cheat leads to another, then more, usually bigger and bigger ones until you get caught and pay the piper for cheating.

      In my world view, the reward in doing the right thing over the long haul is in knowing that your success is honestly yours. I may be taken for a sucker at times, but I generally catch on pretty quick, limit my losses and learn to do better next time. I can also sleep at night because I don't have to keep my stories straight and invent new schemes to keep from being exposed.

      Finally, the old adage "Cheaters never prosper" while not always true, is usually true. And in my long term world view we all face judgment in the end where cheaters will be punished and eventually justice will prevail. So I'm adopting the long term view of doing right.

      So doing right is it's own reward NOW, is in my view less risky for tomorrow, and avoids future punishment in the hear after.... Your mileage may vary on the last one, but the first to are good enough reasons to be honest...

      The rules of life are not "whoever dies with the most toys wins"

      But the rules are "whoever doesn't eat loses". Historically, this was not about accumulating toys, but basic survival. During the Great Leap Forward, 30 million Chinese starved to death. There were another few million deaths from starvation and violence during the Cultural Revolution. Both of those were caused by government abuse and incompetence. Even today, China has a hereditary class system, that denies hundreds of millions of people access to housing, healthcare, and even the right to send their children to public schools. When the system treats you like that, you feel no obligation to be honest in return.

      Striving to live one's life with integrity may not be easy, but then nothing that is really worth doing ever is.

      That is a very western attitude. You should not project your another cultural values onto a culture that does not share them. To the Chinese, it is not 'integrity" that is honorable, but loyalty to your family.
