MattEland.ML.DataFrames 0.0.4

MattEland.ML.DataFrames

This library offers extensions to make working with the Microsoft.Data.Analysis.DataFrame class easier for data wrangling and machine learning workloads.

This code is in early prototyping and the library is not yet meant to be broadly consumed.

Capabilities

The library currently offers the following capabilities:

Removing multiple columns from a DataFrame

Previously in order to remove multiple columns from a DataFrame you needed to create an enumerable and loop over it, removing each column in turn.

This library provides a myDataFrame.Columns.Remove extension method that takes in a params array of column names to remove.

Usage:

int columnsRemoved = myDataFrame.Columns.Remove("ColumnA", "ColumnB", "ColumnC");

Additionally, you can remove all columns except for a few specified columns with the myDataFrame.Columns.RemoveAllBut method.

This is particularly helpful when you want drop all columns not needed for model training.

Usage:

int columnsRemoved = myDataFrame.Columns.RemoveAllBut("ColumnC", "ColumnD");
