Artificial intelligence, often referred to as AI, is a branch of computer science focused on developing systems that exhibit intelligent behavior. Broadly speaking, AI researchers aim to develop technologies that can think and act in a way that mimics human cognition and decision-making [1]. The foundations of AI can be traced back to early philosophical inquiries into the nature of intelligence and thinking. However, AI is generally considered to have emerged as a formal field of study in the 1940s and 1950s. Pioneering computer scientists at the time theorized that it might be possible to extend basic computer programming concepts using logic and reasoning to develop machines capable of “thinking” like humans. Over time, the definition and goals of AI have evolved. Some theorists argued for a narrower focus on developing computing systems able to efficiently solve problems, while others aimed for a closer replication of human intelligence. Today, AI encompasses a diverse set of techniques used to enable intelligent behavior in machines. Core disciplines that contribute to modern AI research include computer science, mathematics, statistics, linguistics, psychology and cognitive science, and neuroscience. Significant AI approaches used today involve statistical classification models, machine learning, and natural language processing. Classification methods are widely applicable to problems in various domains like healthcare, such as informing diagnostic or treatment decisions based on patterns in data. Dean and Goldreich, 1998, define ML as an approach through which a computer has to learn a model by itself from the data provided but no specification on the sort of model is provided to the computer. They can then predict values for things that are different from the values used in training the models. NLP looks at two interrelated concerns, the task of training computers to understand human languages and the fact that since natural languages are so complex, they lend themselves very well to serving a number 展开更多

新时代高质量发展要求要出好酒。然而,好酒除了来源于酿造和蒸馏外,还与储存老熟密切相关。随着科学与技术的发展,人们对储存老熟的机理研究不断深入,缔合作用、吸附作用、溶出和或/萃取作用、氧化作用和缩合反应的新证据、新研究不断... 新时代高质量发展要求要出好酒。然而,好酒除了来源于酿造和蒸馏外,还与储存老熟密切相关。随着科学与技术的发展,人们对储存老熟的机理研究不断深入,缔合作用、吸附作用、溶出和或/萃取作用、氧化作用和缩合反应的新证据、新研究不断出现。应该说,白酒储存老熟是它们共同作用的结果。在此基础上,科技人员开发了诸如加热老熟技术、超高压老熟技术、超重力旋转技术、高电压脉冲电场技术等等新技术,来促进新酒老熟。虽然不能达到真正老酒的水平,但对去除新酒味、改善酒质起到了良好效果。随着“中国白酒169计划”中白酒储存老熟研究项目再启动,相信在不久的将来,我国白酒老熟的研究将更上一个新台阶。 展开更多
