Project Modules

There are no modules declared in this project.

tablesaw-weka-package

Weka package that takes advantage of the tablesaw Java dataframe and visualization library.

Tablesaw dependencies

Use bootstrapp to download all the dependencies (adjust version of tablesaw if necessary):

java -jar bootstrapp-0.1.5-spring-boot.jar --dependency tech.tablesaw:tablesaw-core:0.38.1 --output_dir ./out

Copy all jars from ./out/target/lib into the projects lib directory.

Plugins

Input/Output

  • Loader

    • TableSawCsvLoader - for loading CSV files

  • Saver

    • TableSawCsvSaver - for saving CSV files

Filter

The weka.filters.Tablesaw filter allows you to apply the following table operations:

  • CountBy - generates a table with two columns, the first with the name of the categorical value and the second with the count for that value.
  • First - returns the first X number of rows
  • Last - returns the last X number of rows
  • MissingValueCounts - counts the missing values (outputs single row)
  • MultiTableOperation - applies all specified table operations sequentially
  • PassThrough - dummy, just passes through the data
  • RemoveColumns - removes specified columns
  • RetainColumns - keeps specified columns
  • RemoveColumnsWithMissingValues - drops columns with missing values
  • RemoveRowsWithMissingValues - drops rows with missing values
  • SampleN - generates a sub-sample of size N
  • SampleSplit - splits data into two and returns either first or second part
  • SampleX - generates a sub-sample of proportion X (0.0-1.0)
  • Sort - sorts the data using specified columns (ascending or descending)
  • Summary - generates a summary for the specified column

Note: Since the data needs to be converted into Tablesaw's dataframe format, the data may still get modified (e.g., change in attribute types), despite the PassThrough operation being selected.
