explain Knowledge discovery in database process with steps using BIRCh algorithm and SEER dataset
Data Mining also known as Knowledge Discovery in Databases, refers to the nontrivial extraction of implicit, previously unknown and potentially useful information from data stored in databases.
Steps Involved in KDD Process:
BIRCH (Balanced Iterative Reducing and Clustering using Hierarchies)
Cluster of data points is represented by a triple of numbers (N,LS,SS) Where
N= Number of items in the sub cluster
LS=Linear sum of the points
SS=sum of the squared of the points
A CF Tree structure is given as below:
KDD Process of SEER Databse using Birch algorithm
SEER Dataset represents cancer incidents and mortality rates from various countries across the world.
we can create the clusters using Birch Algorithm. because this algorithm works for huge database.
Data Cleaning :
As it contains the different fields for various countries we can apply the cleaning and Integration process on the data set.
Data Selection and Transformation:
Once the cleaning process is over. apply the Selection of data and remove the use less fields from the data set.
Once the selection of data is over then should start transformation process as it deals with various countries. since the reasons and other fields may not be same in all the countries. we should apply the transformation of data.
After the transformation we need apply the Birch algorithm to create clusters.

Calculate and interpret the z-scores using R. Using the mtcars dataset in R. To complete the assignment, follow the steps below: In the R console, type mtcars. This shows the whole dataset. Using R, calculate the mean and standard deviation for the variables: mpg, cyl, disp, hp, drat, wt, qsec, gear, carb. Using R, calculate the maximum values for the same variables in (b). Using R, calculate the z-scores for the maximum values. Interpret each z-score in (d). Is the...
