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
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.
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.
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.
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
Correct answer: 4
All of the above
All the mentioned reasons are valid as they are responsible for causing uncertainty in the environment.
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
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.
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
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.
