Hierarchical Classification of Single Linkage Euclidean Distance

The classification hierarchy will use Euclidean distance.

The data we will use is as follows:

The initial stage is to calculate data X and data Y.
At this stage, the calculation method is different from the others.
The calculation stages are as follows:

• D1,D1 means (X1-X1) + (Y1-Y1) ^ 1/C1 (using euclidean distance)
• D1,D2 means (X1-X2) + (Y1-Y2) ^ 1/C1 (using euclidean distance)
• D1,D3 means (X1-X3) + (Y1-Y3) ^ 1/C1 (using euclidean distance)
• D1,D4 means (X1-X4) + (Y1-Y4) ^ 1/C1 (using euclidean distance)
• D1,D5 means (X1-X5) + (Y1-Y5) ^ 1/C1 (using euclidean distance)
• D2,D2 means (X2-X2) + (Y2-Y2) ^ 1/C1 (using euclidean distance)
• D2,D3 means (X2-X3) + (Y2-Y3) ^ 1/C1 (using euclidean distance)
• D2,D4 means (X2-X4) + (Y2-Y4) ^ 1/C1 (using euclidean distance)
• D2,D5 means (X2-X5) + (Y2-Y5) ^ 1/C1 (using euclidean distance)
• D3,D3 means (X3-X3) + (Y3-Y3) ^ 1/C1 (using euclidean distance)
• D3,D4 means (X4-X4) + (Y4-Y4) ^ 1/C1 (using euclidean distance)
• D3,D5 means (X5-X5) + (Y5-Y5) ^ 1/C1 (using euclidean distance)
• D4,D4 means (X4-X4) + (Y4-Y4) ^ 1/C1 (using euclidean distance)
• D4,D5 means (X4-X5) + (Y4-Y5) ^ 1/C1 (using euclidean distance)
• D5,D5 means (X5-X5) + (Y5-Y5) ^ 1/C1 (using euclidean distance)

The results are as follows :

Next is to create a matrix diagram :

From the matrix above, we will choose the smallest result except 0 and it turns out that the smallest value is 2,828427125 which belongs to data 3 to 5 and 5 to 3.
We will combine the data to form the following:

    D(35)1
    D(35)2
    D(35)4


The results obtained are as follows:

After getting the data, the smallest value is selected to form a matrix as follows:

After that, the smallest data from the data above is selected again, so that what is obtained is as follows:

    D(352)1
    D(352)4


The results obtained are as follows:

After getting the data, the smallest value is selected to form a matrix as follows :

After that, the smallest data from the data above is selected again, so that what is obtained is as follows:

    D(1234)5

 

The results obtained are as follows:

After getting the data, the smallest value is selected to form a matrix as follows :

From the results above, we can create a diagram, so that the diagram is formed as follows :

Social Problems Arising from Computer Networks (Internet).

Social problems arising from Computer Networks (internet).

The use of the network by the wider community will cause inevitable social, ethical, political, and economic problems. The internet has entered all corners of people's lives, everyone can use it regardless of social status, age, and gender.

The use of the internet will not cause problems as long as the subject is limited to technical, educational or hobby topics, as well as things that are still within the limits of life's norms, but difficulties begin to arise when a site on the internet has a topic that really attracts people's attention, such as politics, religion, sex, etc.

This computer/internet network connection will also cause serious economic problems if the technology is used by certain parties who wish to make personal gains but harm other parties, for example carding activities, downloading commercial software illegally etc.

The pictures posted on internet sites may be something that is normal for some people, but it is very disturbing for some others (because it can cause SARA problems).

In addition, the form of messages is not limited to textual messages. High-resolution color photos and even short video clips can now be easily distributed via computer networks.

While some people may be indifferent, for others the posting of certain material (eg pornography) is unacceptable.
