|
| ## Annotation channels & event types (실측 / measured) |
|
|
| | Sub-database | Channels (typical) | Sampling | Expert events | |
| |---|---|---|---| |
| | Spindles | C3-A1 / FP1-A1 / O1-A1 / EOG | 100 / 200 Hz | 355 spindles | |
| | Kcomplexes | CZ-A1 / FP1-A2 / O1-A2 | 200 Hz | 272 K-complexes | |
| | REMs | CZ-A1 / EOG1 / EOG2 | 200 Hz | 847 REM eye movements | |
| | Artifacts | CZ-A1 / EOG / EMG | 50 Hz | 2000 artifact events (10 sub-types) | |
| | PLMs | CZ-A1 / EMG1-3 | 200 Hz | 4421 PLM events | |
| | Apnea | CZ-A1 / NAF / VTH / VAB / SAO2 | 200 Hz | 4058 hypopnea events | |
| | Subjects | CZ-A1 / FP1-A2 / O1-A2 / EOG | 200 Hz | hypnogram only (5 s epoch) | |
| | Patients | CZ-A1 / FP1-A2 / O1-A2 / EOG | 200 Hz | hypnogram only (5 s epoch) | |
|
|
| ## Hypnogram conventions |
|
|
| DREAMS uses a **5-second epoch** hypnogram (finer than AASM 30-second standard) to align with event-level annotations. |
|
|
| R&K coding: |
| ``` |
| 5 = Wake 4 = REM 3 = N1 2 = N2 1 = N3 0 = N3 (stage 4 merged) -1 = MT/Unscored |
| ``` |
|
|
| `Subjects/Patients` additionally provide AASM-coded hypnograms in `HypnogramAASM_*.txt`. |
|
|
| ## Training plan reference |
|
|
| See [`sleep_event_training_plan.md`](./sleep_event_training_plan.md) for the full 5-class multi-label sleep event classifier training plan combining DREAMS + MASS data. |
