Data Analysis using RapidMiner, WekaDec 2013
I worked on a confidential longitudinal study of publicly held corporate data for UK 180 companies where I carried out term frequency analyses by text mining and association rules generation in Rapid Miner 5.3. I have wide ranging experience of using SPSS and SAS for data analytics, data visualization and statistical techniques. I also have extensive exposure to Machine Leaning using Rapid Miner, R and Weka that are important online data analysis environments. A significant example of this is my previous experience as working at Shaukat Khanum hospital in Lahore. I was part of a team that applied data mining techniques to patient records in order to provide Doctors with a better understanding of their patient profiles. We took 5 year worth or 60,000 of records with 32 attributes and applied the following models: Data cleaning, Statistical findings, analysis of correlation matrix, visualization by histogram and scatter plotting, frequent item-set mining for visualization of association between attributes. This was important because we can’t find the statistical and visual analytics without applying data mining techniques. We delivered a new perspective to staff at the hospital and as a result Doctors were able to deliver enhanced care to patients delivered in a more precise way that was previously not possible. In my another project I was tasked with analyzing a data set of students to evaluate the relative merits of different techniques for analysis. Students had multiple attributes such as nationality, education, attainment levels and other meta-data. I pre-processed the data then I used Rapid Miner to ascertain confidence via frequent item-set mining to find the associations between all attributes. I analysed Graduate student behaviour using given attributes such as student-major, college, student-level, Max-marks and diploma-description. By using frequent item-set generation I explored the relationship of graduate students to attributes such as residency, citizenship, diploma description and gender. I then created data visualizations, qualitative (histogram-analysis) and quantitative (statistical analysis). I also evaluated classification methods and comparing accuracies by using various sampling techniques and criterias e.g. Gini-index, Information goal and Gain ratio. This was important because it provided me insight of student data set and I found that for some attributes K-Mean cluster performed well and for some attributes decision tree gave highest accuracy. Split validation ‘K Nearest Neighbor’s Shuffled sampling technique gave higher accuracy than other sampling techniques.
