The spread of Xenodegree among users is not the same, after some people use Xenodegree, life becomes full of surprises, people are also spiritual, work is interesting, the relationship between husband and wife is harmonious, and some people can't accept a software that will help him make decisions after using Xenodegree, so he uninstalled it after using it once or twice, and told his unlucky situation to the body around him, resisting the use of Xenodegree by the people around him, and now Xenodegree can be said to be two heavens of ice and fire, some users praise, and some users curse.

The mood of opening is very complicated, because the user growth rate of different degrees is very twists and turns, after a wave of explosive growth, there will inevitably be a cliff-like fall, reading the statement every day is the same as looking at the stock market, the mood is seven up and eight down, maybe 100,000 users have increased sharply in the morning, and there may be 70,000 uninstalled in the afternoon, and the opening becomes nervous after a month, and from time to time you have to take out your mobile phone to see the current number of users.

"Manager, the active users of Xenodu have finally stabilized at 1.3 million!" Zhang Kai pointed to the user growth chart of the last month on the computer.

Yang Qing nodded and said: "It's very good, we have stabilized the number of users at 1.3 million in a month, which shows that we are in the right direction!"

Zhang Kai said with a wry smile: "Our registered users are almost 100 million, but only 1.3 million are really used every day, this loss ratio is too big!"

Yang Qing'an said steadily: "Registered users don't mean anything, the key is active users, I believe that as our algorithm becomes more and more perfect, users will definitely continue to spread, and those users who have registered will use Xenodu sooner or later." ”

He nodded and said, "Hmm!"

Yang Qing continued: "Do you have any thoughts on the current 1.3 million active users?"

"That's how I see it!" replied Zhang Kai. Now the active users who use Xenodu they have a very important common characteristic, that is, they have very regular living habits, basically except for the home is the unit, the daily life is basically in addition to the home, other places rarely go, live a two-point and one-line life, the job is stable, and they are very rich, the monthly amount of Xenodu is rarely less than 5000 yuan, which I think is a very important point, after all, the cost of Xenodu automatic execution has a great impact on people with low incomes, the same is 100 yuan, for some users it is the money of a meal, and for some users it may be a week's meal moneyThe automatic consumption behavior of Xenomorph is the biggest reason for unloading, and the people who scold Xenomorph now are basically this group of people. ”

"I think this is a breakthrough point, for people with general income, their consumption in daily life in addition to necessities is very limited, so I think we can adjust the algorithm of Xenodegree to this group of people, and try to help them do something free or low-cost when they use Xenodegree, for these people, it doesn't matter if the takeaway is good or not, the important thing is that it is cheap and full, it doesn't matter whether the movie is premiered or not, the important thing is that it is free, you can stay at home and chase TV series, you will never go out to the mall, you don't need fun in life, you just need to meet the most basic needs。 ”

Yang Qing shook his head when he heard the words and said, " What you said is to divide users into tiers with money, I think whether a person can live happily is not only a matter of looking at money, but also not that they don't like a more interesting life, low income does not mean that their life is not good, on the contrary, people with ordinary income are the most comfortable group of people, the reason why our Xenodegree is not popular in this group of people, is not that Xenodegree spends their money indiscriminately, but Xenodegree has not brought them surprises, Xenodegree has not yet found the G spot of this group of people. ”

"I checked the public behavior tree currently generated by the Xenomorph analysis module, and now Xenodegree's understanding of the interest in life is elegant, high-end, high-end, which may be affected by a lot of consumption upgrade information on the Internet, so that Xenodegree thinks that all people are pursuing personalized products, so he now simply thinks that expensive things are good things, which is no problem in high-income people, but there is a big problem in low-income people, so we don't have to worry, Xenodegree will slowly understand that different users have different needs。

Zhang Kai frowned when he heard this, and said, "You mean that we don't interfere with Xeno's algorithm?"

Yang Qing nodded and said: "That's right! Now the public behavior tree of Xenodu has just been formed, and because the current user group is high-end users, he has only learned how to serve high-end people, and when the scope of the crowd slowly expands, his behavior tree will change, and our child-parent architecture is not perfect now, now it can only be based on the parent end, and the algorithm of the child end still needs more user information to support in order to form a perfect child-mother architecture." ”

"I've always had a question about the parent-child architecture, why don't we store all the user's data in the cloud, but only the behavior tree? If we store all the user's information on the server, wouldn't it be easier for us to accurately predict the user's behavior?"

Yang Qing asked, "Do you know what is the biggest obstacle to the development of artificial intelligence now?"

"The algorithm isn't perfect?" replied Zhang Kai.

Yang Qing shook his head and said, " Wrong, the biggest obstacle is precisely a large amount of data, artificial intelligence needs huge data to feed, but if the data fed to artificial intelligence is wrong, then no matter what, the real artificial intelligence can not be trained, one of the biggest characteristics of information is timeliness, especially information related to people, people are constantly changing, especially demand, a person wants to eat braised pork today, it does not mean that he wants to eat tomorrow, it can only mean that he may want to eat tomorrow, and now many artificial intelligence has fallen into such a strange circle, detecting that a person has ordered braised pork for three consecutive days, and thinks that he likes to eat braised pork all his life, how is this possible, not to mention a lifetime, that is, after a month, this person may change to a vegetarian diet, the needs of users are constantly changing, so it makes no sense for us to store the user's past information. ”

Yang Qing paused here and continued: "Moreover, although everyone is doing this kind of thing of storing user privacy, we must not do it, you look at Penguin's 1 billion users because of privacy problems, there are only 600 million left, and what has the stock price fallen into!"

"If we want to feed Xenogen into a real artificial intelligence, then we must constantly feed him fresh information, and the user's past information must not be fed repeatedly, so that it will interfere with Xeno, and we can't really understand what the user wants now. ”

"I understand, so that's the case, I just said how could he have such a strange feedback in the first place!" Zhang Kai suddenly realized.

Yang Qing couldn't help but be a little curious when he heard Zhang Kai say that his heart was clear: "What strange feedback?"

Zhang Kai explained: " When I was in charge of the big thief group in charge of his heart communication project, I encountered a problem, our thousands of people and thousands of faces of the goods displayed at the beginning of the user's click rate is very high, but after a period of time will continue to decline, and once it declines, it will never come back, every user who has established a model is in this situation, just like an arch bridge, at the beginning of the user's satisfaction continues to rise, after reaching a height it continues to decline, I thought it was a problem with the algorithm at first, but now after listening to your words manager, I understand that it is not that my algorithm has a problem, but that we use it for several months, or even a year ago's user information to predict what users think now, which is really using wrong information to predict user behavior!"

Yang Qing laughed and said: "It's good if you can figure it out!" Speaking of the thousands of people and thousands of faces of the big thief group, I think our Xenodegree can help solve it, and an algorithm for product recommendation can be added to the execution module, what do you think?"

Zhang Kai nodded and said, "There is no problem with this, I think ......"

When Yang Qing and Zhang Kai were discussing the issue of Xenodimension, an Internet bigwig posted an article titled "Real Artificial Intelligence is about to be born" on his personal public account, and the article was published and swiped on the circle of friends, and this article completely detonated Xenodegree on the Internet.
