Chapter 71 Particle Swarm Algorithm
After Yang Youbang left Weilan Company, he made a phone call. Pen ~ fun ~ pavilion www.biquge.info
"Director Geng." Yang Youbang relayed Wei Lan's words with a hard face, "Wei Lan said that he has made some progress in robots, please send someone over to evaluate it." ”
After a pause, Yang Youbang couldn't help but say: "I think he is pampered and arrogant." ”
A little progress has to be evaluated, isn't this pampered and arrogant?
If everybody does this, the government can't be busy?
Director Geng didn't answer directly, but asked rhetorically, "Are you in conflict with him again?" ”
"He has no one in his sights." Yang Youbang said coldly: "If it weren't for your advice, I would have shot him a long time ago." "If you don't have a heart to serve the country, what if you have great talent?
If you want him to say, this kind of person should be shot directly, and he should be imprisoned at the worst, and the government's way of dealing with it is too soft.
Really!
Director Geng sighed, "You are good at everything, but you have a bad temper." "Otherwise, I wouldn't have been sent to the Welland Company as a liaison.
It's called a liaison, but it's really just a dispensing.
This is to appease Welland.
"Alright." Director Geng's face became serious, "I'll call some experts in artificial intelligence to evaluate it later, as for you, try to fulfill your own duties!" ”
"That might be a chance to be brought back."
In just three days, the evaluators got off the plane and got into the vehicle that picked them up and drove to the Welland enterprise, all three of them wearing plaid shirts and a pen pinned to their chests, with serious faces.
It was Yang Youbang who drove the car.
He sent three evaluators all the way to Weilan Company with a tiger face.
"Hello, first time meeting, my name is Peng Yu." Peng Yu, who was the leader, looked at Wei Lan and introduced them one by one: "This is Zhang Wei and Wang Tao. ”
"We are all staff engaged in artificial intelligence, and this time we were called over mainly to see how Mr. Weilan's progress in the field of artificial intelligence is."
"You're welcome." Wei Lan smiled and said, "The main reason for inviting you here this time is that I came up with an idea. ”
He paused and glanced at the three people in front of him silently, but no one spoke, and they all listened.
Only then did he smile with satisfaction, "Everyone knows that the idea of artificial intelligence originated from Aristotle's "Theory of Tools". ”
"In the summer of 1956, a conference was held at Dartmoth University in the United States, at which they first proposed the concept of artificial intelligence."
"At this point, artificial intelligence has become an emerging discipline that integrates mathematics, psychology, neurophysiology, information theory and computer science."
Wei Lan gave a rough introduction to the origin of artificial intelligence, "For the time being, the algorithm of artificial intelligence mainly adopts genetic algorithms. ”
"But although this algorithm has a wide range of applications, it is obviously a little weak in terms of artificial intelligence, so I studied a particle swarm algorithm that is more popular now."
Particle swarm optimization, a parallel algorithm, is a kind of evolutionary algorithm, which is an algorithm that finds the optimal solution by random solution.
"In the process of researching, I added decision trees."
Decision tree is a decision analysis method that intuitively uses probability analysis to obtain the probability that the expected value of the net present value is greater than or equal to zero by constructing a decision tree on the basis of the known probability of occurrence of various situations, evaluating the project risk and judging its feasibility.
"Then I discovered 'artificial intelligence' in a wonderful way, I'll call it 'artificial intelligence' for the time being!" "It's significantly better at decision-making," Welland said. ”
Peng Yu frowned, "Can you show me?" ”
The combination of particle swarm optimization and decision trees is not uncommon in the field of artificial intelligence, and many people have done research on it, but the results can only be considered ordinary.
Obvious optimization, what the hell is that?
Flutter!
Wang Tao smiled, "The combination of particle swarm optimization and decision tree makes artificial intelligence obviously optimized? Sorry, I think I might have heard a joke. ”
Zhang Wei glanced at Wei Lan lightly, and his chin raised slightly, "The combination of particle swarm algorithm and decision tree is not your first creation, and your whimsical ideas are probably difficult to impress us." ”
"Oh, you don't believe it?" Wei Lan looked at them quietly, and thought it was funny in his heart, whether the combination of particle swarm optimization and decision tree worked depends on how well the structure works.
The program structure of artificial intelligence is not good, even the most advanced algorithm cannot play a role, on the contrary, the advanced structure, even if the algorithm is backward, can also play a certain role in optimization.
Peng Yu's face was expressionless.
Believe?
What does he believe?
The combination of particle swarm optimization and decision trees is not new to artificial intelligence, and many people have tried this combination, but unfortunately, the results have not been good.
Wang Tao watched Wei Lan be exposed and still unrepentant, and pouted slightly, "It's so thick-skinned." ”
Zhang Wei did not speak.
He already disdains to speak, an exaggerated academic liar, he is too lazy to speak.
Seeing that the three of them didn't speak and didn't bother to continue explaining, Wei Lan simply jumped over, "...... In order to solve the deduction of artificial intelligence, I added game theory as an optimization strategy. ”
"To use an analogy, prisoner A and prisoner B are captured separately, and they are faced with three choices at the same time."
"The first option, both admitted, both sentenced to ten years; In the second option, one person does not admit it, and the other person admits and identifies the association, then the person will be acquitted, and the person who is designated will be sentenced to 20 years; The third option, which neither of them admitted, would be sentenced to 1 year for the crime of illegally carrying a gun. ”
"Suppose the robot is placed in the position of prisoner A, according to game theory, if you confess guilt, 10 years, and 20 years if you don't admit guilt; 10
