Identity Baseline
A routing lower-bound reference that performs no learning in retrieval experiments, where IRM directly returns the original query representation or a fixed mapping. It is used to measure whether the retrieval mechanism truly learns meaningful set-selection capability after training.
Timeline (last 90 days)
The identity-transform baseline is a routing strategy that does no learning at all; IRM directly returns the raw representation of the query itself or a fixed mapping.
In the evaluation with seven held-out queries, the trained IRM achieved 4/7 correct on top-1 results, versus 3/7 for the identity-transform baseline.
On the identity-related subset, IRM achieved 3/5 correct, versus 1/5 for the identity-transform baseline.
