4D Point Splatting for mmWave Radar Micro-Doppler Differentiable Rendering

task: human pose estimation from mmWave radar
hardware: not stated
simulator: 4DPS
transfer: zero-shot
real result: 21.9 cm MPJPE on real RT-Pose data for a pose model trained on rendered data alone

The paper does not report a comparable success rate on both sides, so the gap cannot be computed.

What the paper says

On RT-Pose, a pose model trained on them alone reaches 21.9 cm MPJPE on real data, against 16.7 cm for real training and 127.6 cm for the RF-Genesis baseline

What it does not report

rendered-data test MPJPE for the rendered-trained pose model
absolute AP for real-trained and rendered-trained HuPR pose models
