Enum: PolaritySemantics¶
Whether the sign of a component map carries meaning. Decomposition methods can return components whose polarity is arbitrary, in which case a negative loading is not a decrease.

Permissible Values¶
| Value | Meaning | Description |
|---|---|---|
| meaningful | None | The sign is interpretable: a negative value means a decrease |
| arbitrary | None | The method could have returned the component with its sign flipped, so a nega... |
| unsigned | None | The values carry no sign at all |
