Is Big Data Just Data?

Richard Marshall at Decision and Data Sciences recently posted a blog entry based in part on conversations during the NIST Big Data Taxonomy and Definitions group meeting.  He brings up a few good points, especially that volume isn’t a new thing in data and velocity is a niche problem.  As initially stated by the chair, Nancy Grady of SAIC, variety of data may be the true litmus test and the factor that changes the management and analysis lifecycles.  Read his full blog at

Predicting the Best Parameters for Federal Business Capture using WEKA

Which contract parameters should I choose?

What combination of features might I pursue to raise my probability of contract award?

  1. Open WEKA explorer
  2. On pre-process tab find the government_contracts.arff file.
  3. Perform pre-processing
    1. Escape non-enclosure single- and double-quotes (\’, \”) if using a delimited text version.
    2. Check ‘UniqueTransactionID’ and click ‘Remove’.  Stating the obvious, there is no value in analysis of a continuous random transaction ID, discretization and local smoothing  can lead to overfitting, and it has no predictive value.
    3. If you have saved the arff back into a csv you will have to filter the ZIP code fields RecipientZipCode and PlaceOfPerformanceZipCode back to nominal with the unsupervised attribute filter StringToNominal and DollarsObligated to numeric.
    4. On the Associate tab, select the Apriori algorithm and click ‘start’.  The results:
