Data to be used (Column 1 = set 1 and Column 2 = set 2)

11. The binary network circuit is characterized by the following transition matrix for the transmission of +1's and-1's. Note that while +1 is received correctly 80% of the time,-1 is received correctly only 75% of the time. If transmission requires 4 of these networks connected in series, what is the probability of receiving +1. If +1 is received, what is the probability that it was transmitted as a +1 0.8 0.25 0.2 0.75 12. (Individual assignments) Two sets of data are provided. The first set consists of the data collected from the IR receiver when no target is present and the second set is the data collected when the target is present. After deteremining the threshold (obtain the peaks of the hostograms and take the mid point), obtain the following a priori probabilities probablities of miss, false alarm sensitivity, specificity positive predictive value accuracy Each student has a file with his/her last name.

Explanation / Answer

Solving question 1 ,Please repost the second individually.

P( +1/1) = 0.8

P(-1/1)=0.2

P(+1/-1)=0.25

P(-1/-1)=0.75

at first,

P( 1) = 0.8

P(-1)=0.2

at 2nd

P(1) = 0.8^2+0.2*0.25 = 0.69

P(-1) = 0.2*0.75+0.8*0.2=0.31

at 3rd

P(1) = 0.69*0.8+0.31*0.25 =0.6295

P(-1) = 0.31*0.75+0.69*0.2=0.3705

at 4th

P(1) = 0.6295*0.8 +0.3705*0.25=0.596225

P(-1) = 0.3705*0.75+0.6295*0.2=0.403775
