OkayImagine that you are preparing to go with your friendsPlay chess, but he is not a human, but a person who does notunderstandthe rules of the game Computer program. Butthis application understands that it is committed to achieving one goal, which is to get in the game Win.
Because the computer program does not know the rules, the moves to start playing chess are random. Some of these tricks make absolutely no sense, and it would be easy for you to win. Suppose here that you enjoy playing chess with this friend so much that you are addicted to the game.
Butthe computer program will eventuallywinbecause it will gradually learn to defeat Your methods and tricksnumber. Although this hypothetical scenario may seem far-fetched, it should give you a general idea of how reinforcement learning (a field of machine learning) works. Basic understanding.
How intelligent is reinforcement learning?
Human intelligence encompasses many characteristics, including acquisition Knowledge, desire to expand intellectual abilities and intuitive thinking. Human intelligence was thrown into doubt when chess champion Garry Kasparov lost to an IBM computer called Deep Blue. In addition to capturing the public's attention, apocalyptic scenarios depicting a future in which robots rule humanity have also dominated mainstream consciousness.
However, "Deep Blue"is not an ordinary opponent. Playing chess with this calculationprogram is like playing chess with a thousand-year-old old Playing games, and hehas been playing chess all his life. But "Deep Blue" is good at playing a specific game, rather than other intellectual activities, such as playing a musical instrument, writing a book, conducting Science experiments, raising children, or repairing cars. This is definitely not intended to belittle what "Deep Blue"
has achievedachievements. Contrary to , the idea that computers can surpass humans in intellectual abilities requires careful examination, starting with an analysis of how reinforcement learning works. How reinforcement learning worksAs mentioned in
, reinforcement Learning is a subset of Machine learning, which involves the concept of how an intelligent agent acts in an environment to maximize cumulative rewards. Simply put, Reinforcement learningRobots are trained by a reward and punishment mechanism, they will make correct actions Get rewards, makewrong actions will be punished. Reinforcement LearningRobots don’t"think"how to take better actions,They simply make all actions possible to maximize the chance of success. The main disadvantage of reinforcement learning is that it requires a large number of resources to achieve its goals. The success of reinforcement learning in the game of Go illustrates this point. This is a popular two-player game where the goal is to occupy the maximum area on the board using your pieces while avoiding losing pieces. AlphaGo Master is a computer program that beats human players in the Go game. It consumes a lot of money and manpower, including many engineers, very Rich gaming experience with 256 GPUs and 128,000 CPUs. The process of learning how to win in competition requires investing a lot of resources and energy. This begs the question: Is it reasonable to design artificial intelligence that cannot think intuitively? Shouldn’t artificial intelligence research try to imitate human intelligence? Support reinforcement One argument for learning is that one should not expect AI systems to act like humans, and that its use in solving complex problems requires further development. On the other hand, the argument against reinforcement learning is that AI research should focus on getting machines to do things that only humans and animals are currently capable of doing. From this perspective, the comparison between artificial intelligence and human intelligence is appropriate. Reinforcement learning is an emerging field that is said to be able to solve some of the above problems. Quantum reinforcement learning (QRL) is a method of accelerating computing. First, Quantum Reinforcement Learning (QRL) should accelerate learning by optimizing the exploration (discovering the strategy) and exploitation (selecting the best strategy) phases. Some current applications and proposed quantum computing improve database searches, factorize large numbers into prime numbers, and more. Although quantum reinforcement learning (QRL) has not emerged in a groundbreaking way, it holds the promise of solving some of the major challenges of conventional reinforcement learning. As mentioned above, reinforcement learning research and Development is crucial. Here are some practical examples of reinforcement learning from a McKinsey & Company survey that can: The power of reinforcement learning may be limited, but it cannot be overestimated. Additionally, as reinforcement learning research and development projects increase, so do the potential use cases in nearly every sector of the economy. Large-scale adoption of reinforcement learning relies on several factors, including optimal algorithm design, configured learning environments, and the availability of computing power.
