# Online Class-Incremental Learning on Letter Source: [Online Class-Incremental Learning on Letter]() Collection index: [llms.txt]() Data updated: 2026-05-13T09:05:20.971Z Evaluation of model performance under an Online Class-Incremental Learning setting using the Letter dataset, measured by Final Mean Accuracy. 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 | Online Class-Incremental Learning | | Dataset (including any stated split) | Letter | | Metric | Final Mean Accuracy | | 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 - [Final Mean Accuracy](): Higher is better; unit: PERCENT. ## Recorded results | Method | Final Mean Accuracy | Result date | Report paper | | --- | --- | --- | --- | | SQDA | 89.5 | Not recorded | 6a0405c2dbc836b87d82777d | | SQDA | 89.5 | Not recorded | 6a0405c2dbc836b87d82777d | | PEC | 76 | Not recorded | 6a0405c2dbc836b87d82777d | | PEC | 76 | Not recorded | 6a0405c2dbc836b87d82777d | | SLDA | 71.8 | Not recorded | 6a0405c2dbc836b87d82777d | | SLDA | 71.8 | Not recorded | 6a0405c2dbc836b87d82777d | | MIST-K | 69.2 | Not recorded | 6a0405c2dbc836b87d82777d | | MIST-K | 69.2 | Not recorded | 6a0405c2dbc836b87d82777d | | MIST-K | 69.2 | Not recorded | 6a0405c2dbc836b87d82777d | | MIST-G | 67.8 | Not recorded | 6a0405c2dbc836b87d82777d | | Rutkowski | 67.8 | Not recorded | 6a0405c2dbc836b87d82777d | | MIST-G | 67.8 | Not recorded | 6a0405c2dbc836b87d82777d | | MIST-G | 67.8 | Not recorded | 6a0405c2dbc836b87d82777d | | Rutkowski | 67.8 | Not recorded | 6a0405c2dbc836b87d82777d | | NCM | 60.2 | Not recorded | 6a0405c2dbc836b87d82777d | | NCM | 60.2 | Not recorded | 6a0405c2dbc836b87d82777d | | RLS | 59.6 | Not recorded | 6a0405c2dbc836b87d82777d | | RLS | 59.6 | Not recorded | 6a0405c2dbc836b87d82777d | | ARF | 56.8 | Not recorded | 6a0405c2dbc836b87d82777d | | ARF-NR | 56.8 | Not recorded | 6a0405c2dbc836b87d82777d | | VFDT | 37.2 | Not recorded | 6a0405c2dbc836b87d82777d | | VFDT | 37.2 | Not recorded | 6a0405c2dbc836b87d82777d | | HAT | 23.7 | Not recorded | 6a0405c2dbc836b87d82777d | | HAT (NR) | 23.7 | Not recorded | 6a0405c2dbc836b87d82777d | | EFDT | 16.8 | Not recorded | 6a0405c2dbc836b87d82777d | | EFDT (NR) | 16.8 | Not recorded | 6a0405c2dbc836b87d82777d | ### SQDA Final Mean Accuracy: 89.5.
