# Vision-and-Language Navigation on R2R Discrete (val-unseen) Source: [Vision-and-Language Navigation on R2R Discrete (val-unseen)]() Collection index: [llms.txt]() Data updated: 2026-02-26T05:53:34.901Z Evaluation of Vision-and-Language Navigation performance on the R2R Discrete dataset using the 'val-unseen' split, reporting metrics including Success Rate (SR), SPL, Navigation Error (NE), Oracle Success Rate (OSR), and Total Length (TL). A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage. | Scope | Recorded value | | --- | --- | | Task | Vision-and-Language Navigation | | Dataset (including any stated split) | R2R Discrete (val-unseen) | | Metric | Navigation Error (NE) | | Unit | SCALAR | | Direction | Lower is better | | Results loaded | 12 of 12 | | Coverage | All results currently returned for this benchmark | Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol. ## Metrics - [Navigation Error (NE)](): Lower is better; unit: SCALAR. - [Total Length (TL)](): Lower is better; unit: SCALAR. - [Oracle Success Rate (OSR)](): Higher is better; unit: PERCENT. - [Success Rate (SR)](): Higher is better; unit: PERCENT. - [SPL](): Higher is better; unit: PERCENT. ## Recorded results | Method | Navigation Error (NE) | Result date | Report paper | | --- | --- | --- | --- | | DUET+ScaleVLN | 2.09 | Not recorded | 6965d1716343fa78c8323446 | | HAMT | 2.29 | Not recorded | 6965d1716343fa78c8323446 | | DUET | 3.31 | Not recorded | 6965d1716343fa78c8323446 | | VLN-BERT | 3.93 | Not recorded | 6965d1716343fa78c8323446 | | SpatialNav | 4.4 | Not recorded | 6965d1716343fa78c8323446 | | SpatialNav | 4.54 | Not recorded | 6965d1716343fa78c8323446 | | PREVALENT | 4.71 | Not recorded | 6965d1716343fa78c8323446 | | MC-GPT | 5.42 | Not recorded | 6965d1716343fa78c8323446 | | SpatialGPT | 5.56 | Not recorded | 6965d1716343fa78c8323446 | | MapGPT | 5.63 | Not recorded | 6965d1716343fa78c8323446 | | NavCoT | 6.36 | Not recorded | 6965d1716343fa78c8323446 | | NavGPT | 6.46 | Not recorded | 6965d1716343fa78c8323446 | ### DUET+ScaleVLN Navigation Error (NE): 2.09.
