Chapter 140: The Evolution of Algorithms
"Why did someone add me in the middle of the night last night?"
"Huh? Is there such a thing? I don't know. Chen Bo pretended to be confused.
Wang Xu was suspicious: "It's strange, it stands to reason that you have nothing to do and push your business card, only you have a criminal record in my friend list." ”
"Maybe it's a new prisoner, think about it, have you added any friends lately?"
Wang Xu recalled: "I forgot to cut my personal account in the library before, and I was crazy to add it. ”
"Are you a star? Why do so many people add you? I'd love to have that, too. ”
"Blame my WeChat name." Wang Xu let out a long sigh.
"Your name? Did you change your name? Chen Bo said curiously.
"I won't tell you, it's time for pleasant gastric lavage again, and I won't eat indiscriminately in the future." After Wang Xu complained, he hung up the phone.
Chen Bo went to look through the address book, found Wang Xu's avatar and looked at it, and almost broke his teeth with laughter.
"[Plus I send a 200 yuan red envelope], do you think more money or less things?"
There was no one to help him keep an eye on the class schedule, and Chen Bo had to get up early every morning to check it, for fear that there would suddenly be something strange.
This elective course is "The Past and Present Life of Computer Algorithms", which is no stranger to Chen Bo, but the current era in which algorithms have developed for decades, and it is difficult to guarantee that there will be no new theoretical knowledge points.
"Everyone else is wearing back to the past to make a fortune, but I'm good, a poor primitive is alone." Chen Bo scratched his head and went out with his keyboard bag.
The teacher is a standard coder, symbolizing the depth of seniority, with an indifferent expression, glasses thick enough to prevent armor piercing, a gray and white plaid shirt, a slightly stiff stride, and fingers that occasionally make keyboard movements.
"Why are there so many people today? Is it because of substitute teacher competition? The teacher pushed his glasses and roughly counted the heads, and the attendance rate was much higher.
"Teacher, I'm going to take this lesson today." The student in the front row reminded.
"Oh, I see, okay." The teacher opened the e-textbook and began to read from the textbook.
Chen Bo is not interested in this part of the content, and there are various computer algorithms, such as recursive method, recursive method, and exhaustive method.
When he was in charge of algorithm recommendation, Chen Bo used the widely used dynamic programming method, that is, to decompose the original problem into sub-problems composed of various factors, and to deduce the optimal solution of the original problem by solving the answers to the sub-problems.
For example, to discuss the changes in consumer purchase demand under different circumstances, we will first list the change factors that affect consumer purchase demand one by one, analyze and draw conclusions, and then summarize all the conclusions to build a model and arrive at the final solution.
The early computer algorithms were far less advanced, and in the era of a certain degree of engine domination of the whole network search in the past few years, the algorithms at that time only stayed in single-line thinking, and they were in the process of searching for melons and melons, and searching for beans and beans.
The vigorous development of Internet advertising business has promoted the innovation of algorithm technology in disguise, and everyone's preferences are very different, and how to deliver advertisements to the target group more accurately has become the first choice for businesses to consider.
In the past, if you put ads to 10 million people, the final conversion rate may be less than 1%, but after achieving accurate delivery, you can put 50 ads to 500,000 people respectively, and the unit price of the latter is 30% cheaper than the former, but the actual effect is far better than several times.
At the same time, the shopping algorithm is also quietly maturing and improving, the early universal Poke did not guess that you like this function, each user's shopping interface is exactly the same, resulting in rampant brushing, if you want to make a profit, you must occupy the home page.
When a headphone enthusiast buys Moyin headphones, the low-end algorithm system will automatically mark them as a headphone preference group, and the user will receive similar product recommendations the next time they log in to the interface, although he doesn't need these at the moment.
The high-end algorithm system will be much more user-friendly, and through massive data processing, the connection between the magic sound headset and other commodities will be established.
Chen Bo has done a similar test before, and the system will make a possibility prediction for different products, and arrange and combine a set of optimal solutions according to the size for user recommendation.
For example, people who like Magic Sound headphones are as likely as high as 87% to like an Apple phone, 83% to like an alien computer, and 78% to like Razer peripherals.
In this way, users will see relevant product pushes when they open the APP next time, and the viewing experience is far better than the previous one.
In the high-level humanized algorithm, the recording permission requested by the APP provides great convenience, which can be regarded as a cheat.
Many times you don't know that you just think that artificial intelligence is really advanced, but you don't know that your words and deeds have long been recorded by the data oligarchs, and when you need to monetize, you will scrape your money bag.
Chen Bo didn't dare to authorize the camera and recording functions, he was worried that the bad things he did in the dead of night would be discovered, and one day he saw the deity haunted in the video, which was called an embarrassment with a capital letter.
The commercialization of algorithms stops here, and the cost of each further step in the future is increased exponentially, you must know that senior algorithm engineers are not cheap, and small-scale start-ups cannot afford to raise them at all.
Input and output are not proportional, if this logic is really applied, there will be no maple nest today.
The international geopolitical situation is changing, and if we want to grasp the strategic initiative in information warfare, it is not possible to stop at a superficial level, and the network algorithm model is not the optimal solution in theory, and there are even more advanced solutions.
To solve this problem, the first contradiction is the information silos among the major monopoly oligopolies.
Due to the need for privacy and confidentiality, the core user data of the four BATMs are almost not disclosed to the public, and the daily behavior of users is divided into several different blocks, and clothing, food, housing, transportation, birth, old age, sickness and death are controlled by different oligarchs.
Only by fully integrating this data can we truly simulate the user's behavior and avoid misjudgments of the integrity of the oral suspect.
The official has done a good job in this regard, Chen Bo has never understood where the superiority of doctrine is embodied, and the textbook gives a clear answer.
Concentrate on doing great things.
When Qualcomm was still fighting with Apple for patent licensing fees for the seventh time, it set off a lawsuit war of the century.
While Google was still negotiating an antitrust settlement with EU officials.
When Amazon was still thinking about whether to sell the sale sale items to Uncle Black at Christmas.
This ancient and mysterious country has completed a magnificent turn of history, and BATM has "taken the initiative" to sign the "User Information Sharing Agreement", aiming to break the information island and build a community with a shared future for mankind.
"It's a battle without gunpowder, and you've lost it since I said it."
This is the original phrase printed in the textbook, and the name is very familiar, it is the artificial intelligence that advocates the eight-hour work week.
