EEG-AffectiveMemory pairs EEG recordings during autobiographical memory recall with the memory's text description, a sketch, an associated musical piece and the participant's affect ratings. It supports the RevisitAffectiveMemory task, which reconstructs affect-contextualized audio-visual memories from EEG. This page holds the data. Code and the pretrained affect extractor are on GitHub.

## Files
| Path | Content |
|---|---|
| `sub-XX/raw/` | Raw EEG of the baseline (`base`) and memory-recall (`task`) sessions (`.edf`, `.easy`, `.nedf`, `.info`) |
| `sub-XX/pped/` | Preprocessed EEG, three steps (EEGLAB `.set` / `.fdt`) |
| `sub-XX/cebra_input/` | Normalized input of the affect extractor (`.csv`) |
| `sub-XX/sub-XX-decoded-matrix.csv` | Decoded affect trajectory |
| `sub-XX/sub-XX-sketch.PNG` | Sketch of the recalled memory |
| `sub-XX/sub-XX-text.txt` | Memory description and the title and link of the associated musical piece (Korean) |
| `text_descriptions.xlsx` | All memory descriptions in one table |
The musical pieces are not included because of copyright. Their titles and links are in `sub-XX-text.txt`.

## Quick start
### 1. Download the data
```bash
hf download kwonjoon/Revisiting-Your-Memory --repo-type dataset --local-dir EEG_AffectiveMemory_dataset
```
### 2. Get the code
```bash
git clone https://github.com/kwxnjoon/Revisiting-Your-Memory.git
```
Place the downloaded folder at `Revisiting-Your-Memory/EEG_AffectiveMemory_dataset/`.
### 3. Run
- Affect extraction: `CEBRA(Affect_Extractor)/` (pretrained model included in the GitHub repository).
- Image and video generation: `image_video_decoding.ipynb`.
- Music generation: put the melody at `sub-XX/sub-XX-melody.wav`, then run `music_generation.ipynb`.
