As a result of neural classification of the table,
ClassifierXL marks the rows of the table with a
cluster number to which this row belongs. For example
you have a table with geographical data that you
need to classify.
Step 1. You click on ClassifierXL from the menu
in MS Excel
After the launch of the program, you will see
the ClassifierXL dialog box.
Step 2. Using the mouse, choose the range of
numerical data of the table that you want to classify
(Source data), and indicate the cell number from
which to start recording the cluster markers (Output).
Step 3. Set the following parameters:
- Number of Categories (clusters).
- Set autofilter. Setting this option allows
you to review the table rows filtered by clusters.
- To One Column/Split Columns. This option
allows to choose between two presentations:
- To One Column: in one column named Clusters,
for each row, you put the cluster number.
- Split Columns: The columns are established
by the number of clusters set in Number
of Clusters option, for example, columns
called Cluster 1, Cluster 2, Cluster 3,
etc. In every column of each row, you put
"1" if the row has fallen into this cluster
and you put "0" if it hasn't.
- Learning rate: Number of epochs and Initial
Neurons Weights set in recommended values. In
most cases there is no need to change them.
- Set colors: Checking this option highlights
each cluster with a different color.
- Calculate averages: Checking this box allows
calculation of averages for each cluster. In
most cases, this is a very important characteristic
of the cluster. The row of cluster averages,
the differentiation of this row from the averages
of other clusters and from the average values
of the whole table, allows category judgments
and additional knowledge mining from the table.
- Calculate minimum: Calculation of minimum
values for each cluster.
- Calculate maximum: Calculation of maximum
values for each cluster.
- Sort table by clusters: Checking this option
allows you to group by clusters in the original
table.
Step 4. Click on the Classify button and get
the following results:
We have three clusters with the following specific
weights.
You can see that 26% of countries fall in Cluster
1, 21% in Cluster 2, and 52% in Cluster 3.
On the basis of Cluster Profile Chart analyses
the following description could be made:
Cluster 1 is a category of countries with big
populations, population growth rate below the average,
big land and water areas, many irrigated lands,
and growth in Gross Domestic Product over the average.
Cluster 2 is a category of countries with population
above the average, population growth that is maximal,
water and land areas are small but with irrigated
land exceeding the average, and GDP growth somewhat
below the average.
Cluster 3 is a category of countries with populations
6 times lower than the average, standard population
growth, water area considerably lower than average,
area of irrigated land far below the average, and
real GDP far below the average rate.
