Protocol
Scope
This planned challenge will evaluate representation transfer across detector contexts. It is intended for methods that learn broadly useful detector embeddings, including contrastive and self-supervised approaches (Oord et al. 2018).
Protocol needs
The final protocol should specify source datasets, held-out target tasks, and the probe suite used for comparison. A minimal transfer score can average normalized probe performance across target tasks,
\[ S_{\mathrm{transfer}} = \frac{1}{T}\sum_{t=1}^{T} \frac{s_t - s_t^{\mathrm{baseline}}} {s_t^{\mathrm{oracle}} - s_t^{\mathrm{baseline}}}. \]
Leaderboard
The leaderboard is not open until the dataset mix and evaluation tasks are fixed. The protocol should explicitly state which detector family is the source, which target family is held out, and whether fine-tuning is allowed.
