This session is about understanding the concept of the mental independent variables.
This is a very important concept.
Now, let's see this with an example.
The height to which the plant grows is dependent on.
The amount of water that is used and the quantity of fertilizers, there are other factors like the
day on which the seeds were planted, whether so many factors.
But let's just look at the factors behind the plant rules.
And the two factors we are analyzing are what you see behind OK as a factor, as if it is.
And fertilizer and what?
OK, so the growth of the combine is dependent on these two.
Why fertilizers of the Department of Energy, something of which we are not concerned as of now, and
so we are considering acres and acres of land is dependent on fertilizers and what?
So in this case.
Quantity of fertilizers and quantity of water are independent variables, and the height of the plant
is dependent variable.
Do you understand this concept?
You have to establish this dependent and independent variables at the start of your machine learning
or deep learning project.
So there's a very, very important concept right now.
Let's see some examples from Real World.
The insurance company is trying to ascertain how much they should charge the customer for insurance.
Right.
So the factors they will consider are age six, BMI.
BMI is body mass index number of children the person has got, whether he's a smoker or not, which
region he or she comes from.
Right.
So all these are independent variables and insurance charges is my dependent variable.
That means quantum of insurance charges is dependent on these factors.
Are you getting it are dependent on these factors?
Now, let's see one more example from the world of banking.
The bank is trying to ascertain whether loans should be granted or not.
OK, and what are the factors the bank is taking into account gender, whether that individual is married
or not, number of dependents, education, whether that individual is self-employed or working for
an organization.
What is applicant's income?
Is that a Koplik and income?
What is the loan amount loan to your credit history and property area?
If you see there are 11 factors, right?
And all these factors are independent variables.
And why should Lorne be granted or not is a dependent variable because should Lorne be granted or not,
is dependent on all these factors, right?
It is like why is a function of X one, X two and so on and so forth.
Right, I hope you're all clear about the concept of dependent on independent variables.
OK.
