一 | “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。但是，在模拟中做一些事情并不总是可能的；例如，如果一个机器人需要与人互动呢？这不是那么容易模拟的，所以你需要真实世界的数据来开始。 Karachi, Oct 15 (UNI) Foreign Minister Bilawal Bhutto-Zardari on Saturday said Pakistan has decided to summon the US ambassador to the Foreign Office to give him a demarche over President Joe Biden’s statement regarding the country’s nuclear capability.
“We know how to safeguard our nuclear arsenal and they meet each and every international standard in accordance with the IAEA (International Atomic Energy Agency) as far as security and safety is concerned,” Bilawal said.
“Pakistan is adamant about ensuring its integrity and safety. Security questions, if any, should be raised on the nuclear weapons of India that recently fired a missile into Pakistani territory by accident.", according to media reports.
Bilawal said he had discussed President Biden's statement with the Prime Minister in detail and hoped this incident would not affect the Pakistan-US relations negatively, Geo news reports.
“This is not only irresponsible and unsafe but raises genuine and serious concerns about the safety of nuclear-capable countries. I am surprised by the remarks of President Biden. I believe this is exactly the sort of misunderstanding that is created when there is a lack of engagement,” the foreign minister said.
"We will make sure our engagements with the US continue in the right direction," Bilawal said.
Bilawal, however, added that he did not think it was an official function and it wasn’t an address to the parliament or an interview.
However, he warned that at the same time the nation should avoid churning out conspiracy theories.
United States President Joe Biden on Saturday said Pakistan may be “one of the most dangerous nations in the world” as the country has “nuclear weapons without any cohesion”.
The US president made the comments while addressing a Democratic congressional campaign committee reception on Thursday.
Biden’s remarks were made with regard to the changing geopolitical situation globally, as he highlighted that the world was changing rapidly, and countries were rethinking their alliances.
“And the truth of the matter is — I genuinely believe this — that the world is looking to us. Not a joke.
"Even our enemies are looking at us to figure out how we figure this out, what we do,” he added.

二 | 你最终会遇到一个鸡和蛋的问题：你没有人类的数据，因为你需要它来制造人类将与之互动的机器人，并首先产生这些数据。Google的研究人员通过简单的开始和制造一个反馈回路来解决这个难题。[i-Sim2Real]使用一个简单的人类行为模型作为近似的起点，在模拟训练和在现实世界中部署之间交替进行。在每次迭代中，人类行为模型和政策都会得到完善。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。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。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。
三 | 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。
