1. Which algorithm is used for solving temporal probabilistic reasoning?

a) Hill-climbing search

b) Hidden markov model

c) Depth-first search

d) Breadth-first search

View Answer

Explanation:Hidden Markov model is used for solving temporal probabilistic reasoning that was independant of transition and sensor model.

2. How does the state of the process is described in HMM?

a) Literal

b) Single random variable

c) Single discrete random variable

d) None of the mentioned

View Answer

Explanation:An HMM is a temporal probabilistic model in which the state of the process is described by a single discrete random variable.

3. What are the possible values of the variable?

a) Variables

b) Literals

c) Discrete variable

d) Possible states of the world

View Answer

Explanation:The possible values of the variables are the possible states of

the world.

4. Where does the additional variables are added in HMM?

a) Temporal model

b) Reality moddel

c) Probability model

d) All of the mentioned

View Answer

Explanation:Additional state variables can be added to a temporal model while

staying within the HMM framework.

algorithm?

a) HMM

b) Restricted structure of HMM

c) Temporary model

d) Reality model

View Answer

Explanation:Restricted structure of HMM allows for a very simple and elegant

matrix implementation of all the basic algorithm.

6. Where does the Hidden Markov Model is used?

a) Speech recognition

b) Understanding of real world

c) Both a & b

d) None of the mentioned

View Answer

Explanation:None

7. Which variable can give the concrete form to the representation of the

transition model?

a) Single variable

b) Discrete state variable

c) Random variable

d) Both a & b

View Answer

Explanation:With a single, discrete state variable, we can give concrete form

to the representationof the transition model.
