A | “Sim2Real”是描述人工智能创造过程的一种方式，其中机器学习模型被教导在虚拟环境或模拟中做什么，然后在现实世界中应用这些知识。当需要多年的试验和错误才能得出一个有效的模型时，这是很有必要的--在模拟中进行，可以在几分钟或几小时内完成多年的实时训练。
B | Dhurandhar director Aditya Dhar broke his silence after a Sikh organisation filed a complaint over a poster showing Ranveer Singh smoking a cigarette while wearing a turban. The filmmaker said that it is an AI-generated image and called it a deliberate actor of misinterpretation. Dhar issued a statement that read, "I am deeply grateful & indebted for the overwhelming love that Dhurandhar The Revenge has received from audience across the country and the world. However, it has come to my attention that certain individuals are circulating manipulated visuals by morphing officially released promotional material using artificial intelligence to create false and misleading narratives." View this post on Instagram A post shared by Aditya Dhar (@adityadharfilms) He continued, "One such fabricated image falsely depicts the character Hamza/Jaskirat smoking while wearing a turban. This is completely untrue and does not form part of the film or any official material released by us. It is a deliberate act of misrepresentation intended to provide and create mischief." Dhar added that he holds the highest respect for the Sikh community and every portrayal has been handled with utmost sensitivity, dignity and responsibility." The filmmaker further urged the audiences to rely only on official content and watch the film as intended and not fall prey to AI-generated misinformation being circulated with an "ulterior motive." "Such acts will be dealt with firmly," Dhar concluded. About Dhurandhar: The Revenge The story continues the journey of Ranveer Singh’s character, an Indian undercover agent operating under the name Hamza. While the first part focused on his infiltration into the dangerous Lyari gang and the assassination of its leader, Rehman Dakait, the sequel takes the narrative forward as Hamza tightens his control over the underworld and its political links. Alongside Ranveer, the Aditya Dhar directorial also features Sanjay Dutt, Rakesh Bedi, R. Madhavan, Sara Arjun, Arjun Rampal, Akshaye Khanna and Danish Pandor among others.

C | 从人类行为的近似值开始是可以的，因为机器人也只是刚刚开始学习。
D | 每场比赛都会收集到更多真实的人类数据，从而提高准确性，让人工智能学习更多。这种方法足够成功，该团队的乒乓球机器人已能够连续对打340次。它还能够将球送回不同的区域，当然不是准确的数学精度，但是好到可以开始执行策略。
E | 该团队还尝试了一种不同的方法，以实现更多的目标行为，比如从不同的位置将球返回到一个非常具体的地方。同样，这并不是要创造终极乒乓球机（尽管这很可能是一个结果），而是要找到有效训练人类互动的方法，而不是让人们重复成千上万次的相同动作。
