Based on the official Data Cleaning Component from Knime: https://hub.knime.com/knime/spaces/Examples/latest/00_Components/Data%20Manipulation/Interactive%20Data%20Cleaning~4e1puCTWR92gydku
This version provides a UI that is better suited for lager datasets/many clumns.
This KNIME component allows you to apply various data cleaning steps interactively. Default configuration will implement cleaning of missing values and outliers.
Availble pre-processing steps:
- Automatic type guessing: determine the most specific type in each string column and change the column types accordingly.
- Treatment of missing values: separate configurations for missing values in string and number columns.
- Outlier removal: configuration on how to treat outliers.
All preprocessing steps have a "Do nothing" option, that will allow to skip the corresponding step.
In addition, you can select and (optionally) rename a subset of columns to be used in the following. If no columns are selected, whole data table will be used.
There is also a summary of the input data presented at the bottom of the page to drive decisions about pre-processing steps.
