# Ad-hoc Video Search on TRECVID (TV18) 2018 (test) Source: [Ad-hoc Video Search on TRECVID (TV18) 2018 (test)]() Collection index: [llms.txt]() Data updated: 2026-02-26T06:09:18.836Z Evaluation of Ad-hoc Video Search performance on the test split of the TRECVID TV18 2018 dataset, typically measured using infAP. 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 | Ad-hoc Video Search | | Dataset (including any stated split) | TRECVID (TV18) 2018 (test) | | Metric | infAP | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 26 of 26 | | 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 - [infAP](): Higher is better; unit: PERCENT. ## Recorded results | Method | infAP | Result date | Report paper | | --- | --- | --- | --- | | LAFF-ml | 14.7 | Not recorded | 68fa6d1f1e209131cea37ecf | | LAFF | 13.7 | Not recorded | 68fa6d1f1e209131cea37ecf | | SEA | 12.8 | Not recorded | 68fa68d31e209131cea1e62d | | SEA + Dual Encoding | 12.8 | Not recorded | 68fa68d31e209131cea1e62d | | Extended Dual Encoding | 12.6 | Not recorded | 68fa68d31e209131cea1e62d | | SEA + SEA | 12.6 | Not recorded | 68fa68d31e209131cea1e62d | | SEA | 12.5 | Not recorded | 68fa68d31e209131cea1e62d | | Rank 1 | 12.1 | Not recorded | 68fa68d31e209131cea1e62d | | Rank 1 finalist | 12.1 | Not recorded | 68fa694b1e209131cea214a4 | | Dual Encoding | 12.1 | Not recorded | 68fa694b1e209131cea214a4 | | Rank 1 | 12.1 | Not recorded | 68fa6d1f1e209131cea37ecf | | Dual Encoding | 11.7 | Not recorded | 68fa68d31e209131cea1e62d | | CLIP2Video | 11.4 | Not recorded | 68fa6d1f1e209131cea37ecf | | VSE++ | 10.6 | Not recorded | 68fa68d31e209131cea1e62d | | VSE++ | 10.6 | Not recorded | 68fa694b1e209131cea214a4 | | W2VV++ | 10.6 | Not recorded | 68fa694b1e209131cea214a4 | | CLIP-FT | 10.5 | Not recorded | 68fa6d1f1e209131cea37ecf | | W2VV | 10.3 | Not recorded | 68fa694b1e209131cea214a4 | | W2VV++ | 10.1 | Not recorded | 68fa68d31e209131cea1e62d | | Rank 2 | 8.7 | Not recorded | 68fa68d31e209131cea1e62d | | Rank 2 finalist | 8.7 | Not recorded | 68fa694b1e209131cea214a4 | | Rank 2 | 8.7 | Not recorded | 68fa6d1f1e209131cea37ecf | | CE | 8.6 | Not recorded | 68fa694b1e209131cea214a4 | | Rank 3 | 8.2 | Not recorded | 68fa68d31e209131cea1e62d | | Rank 3 finalist | 8.2 | Not recorded | 68fa694b1e209131cea214a4 | | Rank 3 | 8.2 | Not recorded | 68fa6d1f1e209131cea37ecf | ### LAFF-ml infAP: 14.7.
