Ludwig Snippets provides code snippets for writing configuration files for Ludwig.

Info: This extension is still under development and it provides only a small subset of Ludwigs configuration items.

Features

You currently can use about 50 snippets to write Ludwig configuration files. The snippets are divided into three categories: Global, Preprocessing, and Encoders. The global snippets help you to bootstrap an ECD configuration, add input and output feature lists, and add global preprocessors. The preprocessing snippets help you to add preprocessors for different types of features. The encoder snippets help you to add encoders for different types of features.

• Bootstrap ECD configurations with ecd.
• Add an input feature list with input-feature-list.
• Add an output feature list with output-feature-list.
• Add a single input or output feature with add-input-feature or add-output-feature.
• Add a global preprocessor with glo-pre and also add a specific split with pre-<type>.
• Add type specific preprocessors by using <type>-preprocessing (or an appriviation). For example:
  • Add binary preprocessor with bin-pre The snippets can be constructed from type and functionality abbreviations. For example, bgpp stands for "bag preprocessor".

Added snippets for encoders. Now you can add encoders for different types of features. Changed the prefix of some snippets for conformity reasons.s

0.1.1

Fixed minor typo issues.

0.1.0
