1) Which of the following is true with respect to uncertainty in AI systems?

1. Uncertainty arises when we are not 100 percent confident in our decisions

2. Whenever uncertainty arises, there is needs to be an estimation taken for getting to any conclusion

3. The AI agent should take certain decisions even in the situations of uncertainty

4. All of the above

Answer & Explanation

Correct answer: 4
All of the above

All the mentioned points are true and valid with respect to uncertainty in AI systems. Also, each point is very important while dealing with uncertainty in AI agents.

1)关于AI系统的不确定性，下列哪一项是正确的？

1. 如果我们对决策没有100％的信心，就会出现不确定性

2. 每当不确定性出现时，都需要做出估计才能得出任何结论

3. 即使在不确定的情况下，AI代理也应做出某些决定

4. 上述所有的

答案与解释

正确答案：4
上述所有的

关于人工智能系统中的不确定性，所有提到的观点都是真实有效的。 同样，在处理AI代理的不确定性时，每一点都很重要。

2) Which of the following mentioned statements are uncertain?

1. The number occurred on rolling a die.

2. What will the temperature tomorrow?

3. What card will be get on picking a card from a fair deck of 52 cards?

4. What output will we get on tossing a coin?

Options:

1. Only iv.

2. All i., ii., iii. and iv.

3. ii. and iv.

4. Only ii.

Answer & Explanation

Correct answer: 2
All i., ii., iii. and iv.

We cannot be 100% sure about the output we get on tossing a die, coin or picking a card, or the upcoming day’s temperature as it depends on various factors which are almost impossible to monitor accurately. Hence we have uncertainty there.

2)以下哪些陈述不确定？

1. 该数字发生在模具旋转时。

2. 明天温度是多少？

3. 从公平的52张牌中挑选一张牌会得到什么牌？

4. 我们扔硬币会得到什么输出？

选项：

1. 只有iv。

2. 全部i。，ii。，iii。 iv。

3. ii。 iv。

4. 只有ii。

答案与解释

正确答案：2
全部i。，ii。，iii。 iv。

我们不能百分百确定我们继续掷骰子，硬币或捡卡所获得的输出，或即将到来的一天的温度，因为它取决于几乎无法精确监控的各种因素。 因此，那里存在不确定性。

3) Which of the mentioned points are valid reasons for uncertainty in the nature?

1. Partially observable environment

2. Dynamic nature of the environment

3. Inaccessible area in the environment

4. All of the above

Answer & Explanation

Correct answer: 4
All of the above

All the mentioned reasons are valid as they are responsible for causing uncertainty in the environment.

3)上述哪几点是自然界不确定性的正当理由？

1. 部分可观察的环境

2. 环境的动态性质

3. 环境中无法进入的区域

4. 上述所有的

答案与解释

正确答案：4
上述所有的

所有提到的原因都是有效的，因为它们是造成环境不确定性的原因。

4) Consider the following statement:
"When we talk about perceiving information from the environment, then the main problem that arises is that there is always some uncertainty is our observations. This is because the world is an enormous entity and the surroundings that we take under study are not always well defined. So, there is needs to be an estimation taken for getting to any conclusion."
Which among the following takes the best decisions in a situation with uncertainty?

1. AI based agents

2. Humans

3. Animals

4. None of the above

Answer & Explanation

Correct answer: 2
Humans

Human being face this uncertainty daily that too many times. But still, they manage to make successful decisions. This is because humans have strong estimating and decision making power and their brains function in such a way that every time such a situation arises, the alternative with the maximum positive output is chosen.

4)考虑以下陈述：
“当我们谈论从环境中感知信息时，出现的主要问题是我们的观察总是存在一些不确定性。这是因为世界是一个巨大的实体，我们所研究的周围环境并不总是很清晰因此，需要做出任何估计才能得出结论。”
在不确定的情况下，以下哪项是最佳决策？

1. 基于AI的代理

2. 人类

3. 动物

4. 以上都不是

答案与解释

正确答案：2
人类

人类每天要面对这种不确定性太多次。 但是，他们仍然可以做出成功的决定。 这是因为人类具有强大的估计和决策能力，并且大脑的功能使每次出现这种情况时，都会选择具有最大正输出的替代方案。

5) State whether the following condition is true or false?
"The cases of uncertainty mostly happen in those cases where the conditions are neither completely true nor completely false."

1. True

2. False

Answer & Explanation

Correct answer: 1
True

Uncertainty arises when we are not 100 percent sure about the outcome of the decisions. This mostly happens in those cases where the conditions are neither completely true nor completely false.

5)陈述以下条件是对还是错？
“不确定性的情况大多发生在条件既不完全正确也不完全错误的情况下。”

1. 真正

2. 假

答案与解释

正确答案：1
真正

当我们不能100％确定决策结果时，就会出现不确定性。 这大多发生在条件既不完全正确也不完全错误的情况下。
