# Chord Recognition on uspop2002 170-label large vocabulary (val) Source: [Chord Recognition on uspop2002 170-label large vocabulary (val)]() Collection index: [llms.txt]() Data updated: 2026-02-26T06:02:24.747Z Evaluation of Chord Recognition performance on the validation split of the uspop2002 170-label large vocabulary dataset, measured using detailed chord structure metrics (Root, Thirds, Triads, etc.) and MIREX. 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 | Chord Recognition | | Dataset (including any stated split) | uspop2002 170-label large vocabulary (val) | | Metric | Root | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 5 of 5 | | 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 - [Root](): Higher is better; unit: PERCENT. - [Thirds](): Higher is better; unit: PERCENT. - [Triads](): Higher is better; unit: PERCENT. - [Sevenths](): Higher is better; unit: PERCENT. - [Tetrads](): Higher is better; unit: PERCENT. - [Maj-min](): Higher is better; unit: PERCENT. - [MIREX](): Higher is better; unit: PERCENT. ## Recorded results | Method | Root | Result date | Report paper | | --- | --- | --- | --- | | BTC | 80.51 | Not recorded | 695c970253fdd5c3617436ed | | BMACE | 80.43 | Not recorded | 695c970253fdd5c3617436ed | | CRNN | 80.26 | Not recorded | 695c970253fdd5c3617436ed | | MACE-H | 78.33 | Not recorded | 695c970253fdd5c3617436ed | | MACE-V | 77.39 | Not recorded | 695c970253fdd5c3617436ed | ### BTC Root: 80.51.
