## In one sentence

Recovers up to 49% missing data in OptiTrack piano hand motion capture using TimesNet-based outlier detection and deep-learning imputation.

옵티트랙 피아노 손 모션캡처에서 최대 49%에 이르는 결측을, TimesNet 기반 이상치 검출과 SAIT 기반 딥러닝 보간으로 복원했다.

## Key facts

- ~2 hours of motion capture from one professional pianist
- Up to 49% missing values during capture
- MCAR 20% test: MAE 0.2482, RMSE 0.4948

## When this paper is relevant

- You impute missing motion-capture data with deep learning / 딥러닝으로 모션캡처 결측을 보간(imputation)할 때
- You want statistics on missing-data patterns in piano hand motion / 피아노 손 모션 데이터의 결측 패턴 통계를 알고 싶을 때
