| # Stateful Classes | |
| Below are variations of a [singleton class](https://en.wikipedia.org/wiki/Singleton_pattern) in the sense that all | |
| instances share the same state, which is initialized on the first instantiation. | |
| These classes are immutable and store information about certain configurations or | |
| states. | |

| [[autodoc]] state.GradientState |
