@zareen said in BIF601 GDB 1 Solutoion and Discussion:

Discuss different types of Machine Learning and Differentiate False +VE and False –VE, How they are significant?

Solution Idea:
In this section, we’ll define the primary building blocks of the metrics we’ll use to evaluate classification models. But first, a fable:

An Aesop’s Fable: The Boy Who Cried Wolf (compressed)

A shepherd boy gets bored tending the town’s flock. To have some fun, he cries out, “Wolf!” even though no wolf is in sight. The villagers run to protect the flock, but then get really mad when they realize the boy was playing a joke on them.

[Iterate previous paragraph N times.]

One night, the shepherd boy sees a real wolf approaching the flock and calls out, “Wolf!” The villagers refuse to be fooled again and stay in their houses. The hungry wolf turns the flock into lamb chops. The town goes hungry. Panic ensues.

Let’s make the following definitions:

“Wolf” is a positive class.

“No wolf” is a negative class.

We can summarize our “wolf-prediction” model using a 2x2 confusion matrix that depicts all four possible outcomes:
True Positive (TP): False Positive (FP): Reality: A wolf threatened. Reality: No wolf threatened. Shepherd said: “Wolf.” Shepherd said: “Wolf.” Outcome: Shepherd is a hero. Outcome: Villagers are angry at shepherd for waking them up. False Negative (FN): True Negative (TN): Reality: A wolf threatened. Reality: No wolf threatened. Shepherd said: “No wolf.” Shepherd said: “No wolf.” Outcome: The wolf ate all the sheep. Outcome: Everyone is fine.
A true positive is an outcome where the model correctly predicts the positive class. Similarly, a true negative is an outcome where the model correctly predicts the negative class.

A false positive is an outcome where the model incorrectly predicts the positive class. And a false negative is an outcome where the model incorrectly predicts the negative class.

In the following sections, we’ll look at how to evaluate classification models using metrics derived from these four outcomes.

Assignment No: 01
Question #1: Find the root of the equation, Perform three iteration of the equation,
ln (x −1) + sinx =0 by using Newton Raphson method.

Ans: Let f(x) = ln(x+1) + sinx = 0 and f(x) = 1/(x-1) + cosx

F (1.5) = ln(0.5) + (1.5) = - 0.0667

F(2) = ln(1) + sin(2) = 0.035

Since f (1.5) f (2) < 0 so roots lies in interval [1.5, 2]

Let x0 = 1.75 . x0 can be taken in the interval any real number [ 1.5 , 2 ], we let mid point

of this interval .
As we know Newton Raphson method is

Xn+1 = xn – f ( xn ) / f(xn)
First iteration
X1 = x0 –f(x0) / f(x0) = 1.75 - f(1.75) / f(1.75)
= 1.75 – (-0.2571 / 2.3329) = 1.8602
Second iteration:
X2 = x1 - f(x) / f(x) = 1.8602 –[ f(1.8602) / f(1.8602)]
= 1.8602 - ( -0.1181 / 2.1620 ) = 1.9148
Third iteration:
X3 = x2- f(x2) / f(x2) = 1.9148 –f(1.9148) / f(1.9148)
= 1.9148 – [-0.0556/2.0926]
= 1.9414
Question #2: Solve the system of linear equations with the help of Gaussian elimination method.
x + y + z = 6;2x − y + z = 3;x + z = 4

ANS: In Gaussian elimination method we convert the augmented matrix into reduce

Echelon form therefore,

Augmented matrix is

R2- 2R1 , R3 – R1

-1R2 , -1R3
R23
R3-3R2

X + Y+ Z = 6 ;………………….(1)
Y = 2,
Z = 3
Put into eq (1),
we get X = 1 ,
