Robo3D Benchmark

The following metrics are consistently used in our benchmark:

• Mean Corruption Error (mCE):

  • The Corruption Error (CE) for model $A$ under corruption type $i$ across 3 severity levels is: $\text{CE}_i^{\text{Model}A} = \frac{\sum((1 - \text{mIoU})^{\text{Model}A})}{\sum((1 - \text{mIoU})^{\text{Baseline}})}$.
  • The average CE for model $A$ on all $N$ corruption types, i.e., mCE, is calculated as: $\text{mCE} = \frac{1}{N}\sum\text{CE}_i$.

• Mean Resilience Rate (mRR):

  • The Resilience Rate (RR) for model $A$ under corruption type $i$ across 3 severity levels is: $\text{RR}_i^{\text{Model}A} = \frac{\sum(\text{mIoU}^{\text{Model}A})}{3\times (\text{clean-mIoU}^{\text{Model}A})} .$
  • The average RR for model $A$ on all $N$ corruption types, i.e., mRR, is calculated as: $\text{mRR} = \frac{1}{N}\sum\text{RR}_i$.
