ScenarioTableCoverageScenario

Robotics scenarios · Implementation: mlsysim/engine/scenario_definitions/robotics/demonstrations.py.

Construct this scenario with keyword inputs. The fields below show the types and defaults declared by this class.

A scenario table of offsets by speeds joined against an archive demonstrated within logged_offset at demonstrated_speed, plus recovery collections at added_offsets.

Notes

Equation: Supported cells require the demonstrated speed and an offset in the logged interval or added set.

Assumptions: Exact discrete matching, with no extrapolation between speed values.

Excludes: A claim of safety or generalization outside demonstrated cells.

References

Derivation: Support is an explicit set-membership rule on discrete offset/speed pairs: speed must match exactly, and offset must lie within the logged interval or the supplied added set. Enumerating the Cartesian table counts support; subtraction counts absence.

Examples

The named registry scenario supplies the stated inputs; this is a modeled calculation, not a new measurement.

>>> from mlsysim import Scenarios
>>> scenario = Scenarios.LatchScenarioTable
>>> scenario.supported
