ISY310 Data Mining and Business Intelligence-Survey Process Collection.
Decide on the data to be used for analysis. Criteria include relevance to the data mining goals, quality and technical constraints such as limits on data volume or data types.
Raise the data quality to the level required by the selected analysis techniques. This may involve selection of clean subsets of the data, the insertion of suitable defaults or more ambitious techniques such as the estimation of missing data by modeling.
Describe the decisions and actions that were taken to address the data quality problems reported during the Verify Data Quality Task. The report should also address what data quality issues are still outstanding.
Answer:
During the analysis, the set of data that are to be used has been collected from students of the university on the form of survey. In the survey the main roles played is by uncovering the modeling techniques and various analytics Data Mining. For the completion of this report, all the methods will be utilized as well as for the conventional questions to be answered, which are required to complete the analysis of this report. All these data sets are found in the survey process collection.
Defining the complex data while keeping in mind the goal of the task and hence gathering the data of the certain areas and data rows. The total collected data rows were almost 2000 that has been collected from different participants in the surveys. The data rows that have been removed had the following reasons:
- A row in the age group has a value of -548. Since this, an invalid range of data thus the value is unacceptable and is discarded from the row.
- The ‘Country of Birth’ column collected data for the value {0, 1, 2, 3}.
- Data present in the column are in the area of major, minor and residence.
- Blank data in rows cannot be utilized in the analysis.
Cleaning the data sets has been done on considering the above point and finally 1918 rows of data could be considered appropriate for the final analysis of the report.
Within the data sets all the data forms have been changed, if it was done within the texts the value could have hampered the process of creating the model building procession. The collected data has been used keeping in mind the clearance that has been done because of the unwanted data, which cannot be utilized in the analysis any further.
No new construction has been done in the column of data since all the data set has been gathered from the survey are thoroughly checked. Hence, new columns were not added in the data sets any further.
Excel sheet has been used to compile the above chart. Acceptance of the loan against the mode of study mapping has been done for the display in the chart. Acceptance of loan values, 0 as NO and 1 as YES. The mode of study determination can be further described as: 0 is F/T; 1 as P/T and 2 as external. As per the records of the chart given the highest values has been displayed of the student who are not willing to accept the loans and on a full time basis are willing to complete the course.
Excel sheet has been used to compile the above chart. From the chart we can observe that the students agreeing for the acceptance of loans depends on the mode of payment, since reliable the method easier to pay. Acceptance of loan values, 0 as NO and 1 as YES. The mode of payment 0 is HECS, 1 as by own medium and 2 for other. As per the record, the highest numbers of the students are of those who are willing to accept the loan technique and pay by HECS.
Excel sheet has been used to compile the above chart. From the chart, we can observe the loan acceptance of the students with respect to the current GPA of the student. Acceptance of loan values, 0 as NO and 1 as YES. Range of GPA ranges from 1 to 4, with each count of slabs. As per the records in the charts the highest number has been displayed, the records are of the students who are not willing to take loans and have GPA valuing 2.
There are two parts in which the splitting has been done in the data set analysis based on the characteristics of 66% of the whole set of data. In model building process data sets are used and rest of the data are used for the test procedure execution processes. Weka has been used for the divisions and thus manual divisions were not required. After this analysis the reports starts proceeding towards the building section of the models.
The analysis used three major algorithms:
- Linear Regression: A linear approach that is used in the modeling to establish between an independent variable and a scalar variable.
- Multi-Layer Perception: artificial to the nature this is known to be a feedback to the neutral network that consists of minimum 3 layers.
- Random Tree: Selecting the major sets and has the possibility of turning into a tree are possibly be modeled.
For further analysis has the parameter in the column of “would accept loan”. It has been helpful to understand the perspective of the students about their willingness to take the loan or not from the university bank.
The rule-based analysis is the decision tree:

Linear regression also falls under the form of opaque model:

The analyzed data depends on the column of “would accept loan”. The survey participants were selected based on the analysis of the university that resembles some form of loans. Based on the analysis we can describe weather the student is able to accept the loan or not, again on full time basis or per time basis. Single kind of data is not sufficient to make the decision in the case of analysis and thus the report to contain the collected data. Hence, the analysis has been done based on collected data sets. The equation that stands for this report: “RESULTS = MODELS + FINDINGS”.
The report contains three forms of model building process:
- Linear Regression
- Random tree
- Multi-Layer Perception
In the required analytical data set can be used as model of Linear Regression for its simplicity. Multi-Layer Perceptions time consuming helps in finding the data. This also requires many training completion for the analysis of the Random Tree in data sets. This is visualized on large scale, which is more difficult to understand keeping in mind the best outcome that we can get from the analysis.
