14. [Optional] Notebook + Quiz: Other Encodings
There is a key difference between the binary 1, 0 encodings that you've been working with, and the -1, 0, 1 encoding system: In the 1, 0 coding system, comparisons are to the baseline category as we've discussed, whereas in the 1, 0, -1 coding system comparisons are to the overall average .
The coding has all been done in this notebook. In this optional concept, you may study the notebook and interpret the results in the quiz questions below.
Workspace
This section contains either a workspace (it can be a Jupyter Notebook workspace or an online code editor work space, etc.) and it cannot be automatically downloaded to be generated here. Please access the classroom with your account and manually download the workspace to your local machine. Note that for some courses, Udacity upload the workspace files onto https://github.com/udacity , so you may be able to download them there.
Workspace Information:
- Default file path:
- Workspace type: jupyter
- Opened files (when workspace is loaded): n/a
