Which of the following is untrue regarding the gap penalty used in dynamic programming?
Gap penalty is subtracted for each gap that has been introduced
Gap penalty is added for each gap that has been introduced
The gap score defines a penalty given to alignment when we have insertion or deletion
Gap open and gap extension has been introduced when there are continuous gaps (five or more)
Which of the following does not describe dynamic programming?
The approach compares every pair of characters in the two sequences and generates an alignment, which is the best or optimal
Global alignment algorithm is based on this method
A local alignment aligns a substring of the query sequence to a substring of the target sequence
The method can be useful in aligning protein sequences to protein sequences only
Which of the following does not describe global alignment algorithm?
In initialization step, the first row and first column are subject to gap penalty
Score can be negative
In trace back step, beginning is with the cell at the lower right of the matrix and it ends at top left cell
First row and first column are set to zero
Which of the following is not true about Markov Chains
a system (Q,A) consisting of a finite set of states and a transition
state xi , and at the tick of a clock the chain changes to state xi+1
Markov chain cannot be recursive
is used for solving temporal probabilistic reasoning that was independent of transition and sensor model
Knowing the above transition matrix, "AATC" is a positive model or a negative model?
Positive
Negative
Undefined
Non of above
Viterbi Algorithm is used for:
Decoding – finding the most likely path
Evaluation – computing observation likelihood
Training – estimating parameters
Non of above
In Neural Networks, the fundamental unit of network is

What is perceptron?
a single layer feed-forward neural network with pre-processing
an auto-associative neural network
a double layer auto-associative neural network
a neural network that contains feedback
Where does the chemical reactions take place in neuron?
dendrites
axon
synapses
nucleus
Which of the following does not present differentiation of one ANN network from another?
architecture
back-propagation algorithm
size of the input vector
mathematical functions
