1
00:00:01,990 --> 00:00:08,600
This session is about understanding the concept of the mental independent variables.

2
00:00:09,250 --> 00:00:10,750
This is a very important concept.

3
00:00:11,500 --> 00:00:13,900
Now, let's see this with an example.

4
00:00:16,220 --> 00:00:21,590
The height to which the plant grows is dependent on.

5
00:00:22,740 --> 00:00:31,700
The amount of water that is used and the quantity of fertilizers, there are other factors like the

6
00:00:31,710 --> 00:00:36,750
day on which the seeds were planted, whether so many factors.

7
00:00:37,530 --> 00:00:42,390
But let's just look at the factors behind the plant rules.

8
00:00:42,810 --> 00:00:53,000
And the two factors we are analyzing are what you see behind OK as a factor, as if it is.

9
00:00:53,280 --> 00:00:57,030
And fertilizer and what?

10
00:00:58,200 --> 00:01:03,510
OK, so the growth of the combine is dependent on these two.

11
00:01:04,590 --> 00:01:15,170
Why fertilizers of the Department of Energy, something of which we are not concerned as of now, and

12
00:01:15,450 --> 00:01:21,150
so we are considering acres and acres of land is dependent on fertilizers and what?

13
00:01:24,620 --> 00:01:26,090
So in this case.

14
00:01:27,030 --> 00:01:33,210
Quantity of fertilizers and quantity of water are independent variables, and the height of the plant

15
00:01:33,480 --> 00:01:35,070
is dependent variable.

16
00:01:35,910 --> 00:01:37,320
Do you understand this concept?

17
00:01:37,980 --> 00:01:44,100
You have to establish this dependent and independent variables at the start of your machine learning

18
00:01:44,100 --> 00:01:45,220
or deep learning project.

19
00:01:45,480 --> 00:01:48,930
So there's a very, very important concept right now.

20
00:01:48,940 --> 00:01:51,200
Let's see some examples from Real World.

21
00:01:51,960 --> 00:01:59,310
The insurance company is trying to ascertain how much they should charge the customer for insurance.

22
00:01:59,310 --> 00:01:59,680
Right.

23
00:01:59,970 --> 00:02:04,440
So the factors they will consider are age six, BMI.

24
00:02:04,470 --> 00:02:12,630
BMI is body mass index number of children the person has got, whether he's a smoker or not, which

25
00:02:12,630 --> 00:02:14,020
region he or she comes from.

26
00:02:14,180 --> 00:02:14,530
Right.

27
00:02:14,910 --> 00:02:22,870
So all these are independent variables and insurance charges is my dependent variable.

28
00:02:22,890 --> 00:02:30,170
That means quantum of insurance charges is dependent on these factors.

29
00:02:31,590 --> 00:02:35,270
Are you getting it are dependent on these factors?

30
00:02:36,390 --> 00:02:39,720
Now, let's see one more example from the world of banking.

31
00:02:40,440 --> 00:02:44,260
The bank is trying to ascertain whether loans should be granted or not.

32
00:02:44,740 --> 00:02:51,510
OK, and what are the factors the bank is taking into account gender, whether that individual is married

33
00:02:51,510 --> 00:02:58,140
or not, number of dependents, education, whether that individual is self-employed or working for

34
00:02:58,140 --> 00:02:59,090
an organization.

35
00:02:59,460 --> 00:03:00,930
What is applicant's income?

36
00:03:02,290 --> 00:03:04,100
Is that a Koplik and income?

37
00:03:04,540 --> 00:03:09,130
What is the loan amount loan to your credit history and property area?

38
00:03:09,140 --> 00:03:11,710
If you see there are 11 factors, right?

39
00:03:12,010 --> 00:03:16,120
And all these factors are independent variables.

40
00:03:17,190 --> 00:03:25,170
And why should Lorne be granted or not is a dependent variable because should Lorne be granted or not,

41
00:03:25,170 --> 00:03:28,220
is dependent on all these factors, right?

42
00:03:28,350 --> 00:03:33,660
It is like why is a function of X one, X two and so on and so forth.

43
00:03:34,840 --> 00:03:42,400
Right, I hope you're all clear about the concept of dependent on independent variables.

44
00:03:43,090 --> 00:03:43,540
OK.
