Choosing a tool in Watson Studio
Watson Studio provides a range of tools for users with all levels of experience in preparing, analyzing, and modeling data, from beginner to expert.
To pick the right tool, consider these factors.
- The type of data you have
-
- Tabular data in delimited files or relational data in remote data sources
- Image files
- Textual data in documents
- The type of tasks you need to do
-
- Prepare data: cleanse, shape, visualize, organize, and validate data.
- Analyze data: identify patterns and relationships in data, and display insights.
- Build models: build, train, test, and deploy models to classify data, make predictions, or optimize decisions.
- How much automation you want
-
- Code editor tools: Use the Jupyter notebook editor or the RStudio IDE to write code to work with any type of data and do any type of task.
- Graphical canvas tools: Use menus and drag-and-drop to visually program. Build dashboards to analyze data or build multi-step flows to prepare data, analyze data, or build models.
- Automatic builder tools: Use to build and train models with very limited user input.
