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

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

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

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

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)關(guān)于AI系統(tǒng)的不確定性，下列哪一項(xiàng)是正確的？

如果我們對(duì)決策沒有100％的信心，就會(huì)出現(xiàn)不確定性

每當(dāng)不確定性出現(xiàn)時(shí)，都需要做出估計(jì)才能得出任何結(jié)論

即使在不確定的情況下，AI代理也應(yīng)做出某些決定

上述所有的

答案與解釋

正確答案：4
上述所有的

關(guān)于人工智能系統(tǒng)中的不確定性，所有提到的觀點(diǎn)都是真實(shí)有效的。 同樣，在處理AI代理的不確定性時(shí)，每一點(diǎn)都很重要。

2) Which of the following mentioned statements are uncertain?

The number occurred on rolling a die.

What will the temperature tomorrow?

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

What output will we get on tossing a coin?

Options:

Only iv.

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

ii. and iv.

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)以下哪些陳述不確定？

該數(shù)字發(fā)生在模具旋轉(zhuǎn)時(shí)。

明天溫度是多少？

從公平的52張牌中挑選一張牌會(huì)得到什么牌？

我們?nèi)佑矌艜?huì)得到什么輸出？

選項(xiàng)：

只有iv。

全部i。，ii。，iii。 iv。

ii。 iv。

只有ii。

答案與解釋

正確答案：2
全部i。，ii。，iii。 iv。

我們不能百分百確定我們繼續(xù)擲骰子，硬幣或撿卡所獲得的輸出，或即將到來的一天的溫度，因?yàn)樗Q于幾乎無法精確監(jiān)控的各種因素。 因此，那里存在不確定性。

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

Partially observable environment

Dynamic nature of the environment

Inaccessible area in the environment

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)上述哪幾點(diǎn)是自然界不確定性的正當(dāng)理由？

部分可觀察的環(huán)境

環(huán)境的動(dòng)態(tài)性質(zhì)

環(huán)境中無法進(jìn)入的區(qū)域

上述所有的

答案與解釋

正確答案：4
上述所有的

所有提到的原因都是有效的，因?yàn)樗鼈兪窃斐森h(huán)境不確定性的原因。

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?

AI based agents

Humans

Animals

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)考慮以下陳述：
“當(dāng)我們談?wù)搹沫h(huán)境中感知信息時(shí)，出現(xiàn)的主要問題是我們的觀察總是存在一些不確定性。這是因?yàn)槭澜缡且粋€(gè)巨大的實(shí)體，我們所研究的周圍環(huán)境并不總是很清晰因此，需要做出任何估計(jì)才能得出結(jié)論。”
在不確定的情況下，以下哪項(xiàng)是最佳決策？

基于AI的代理

人類

動(dòng)物

以上都不是

答案與解釋

正確答案：2
人類

人類每天要面對(duì)這種不確定性太多次。 但是，他們?nèi)匀豢梢宰龀龀晒Φ臎Q定。 這是因?yàn)槿祟惥哂袕?qiáng)大的估計(jì)和決策能力，并且大腦的功能使每次出現(xiàn)這種情況時(shí)，都會(huì)選擇具有最大正輸出的替代方案。

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."

True

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)陳述以下條件是對(duì)還是錯(cuò)？
“不確定性的情況大多發(fā)生在條件既不完全正確也不完全錯(cuò)誤的情況下。”

真正

假

答案與解釋

正確答案：1
真正

當(dāng)我們不能100％確定決策結(jié)果時(shí)，就會(huì)出現(xiàn)不確定性。 這大多發(fā)生在條件既不完全正確也不完全錯(cuò)誤的情況下。
