Synthetic data generation pipeline improves indoor radio-map prediction

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel pipeline for generating synthetic indoor layouts and a fast, open-source approximate ray tracer to create radio maps. This approach allows for large-scale pretraining of models like ResNet-101 and Swin Transformer, generating 128 million synthetic samples. Despite simulator mismatch, the pretrained ResNet-101 model demonstrated a 15% reduction in error on average across five indoor radio-map prediction tasks and showed improved transfer learning on real-world data. The study also confirmed predictable data-scaling trends, with power laws accurately predicting downstream performance based on smaller sample sizes. AI

IMPACT This research could lead to more efficient and accurate indoor radio-map prediction models by leveraging large-scale synthetic data.

    Scaling Cheap Synthetic Pretraining Improves Indoor Radio-Map Prediction

    arXiv:2610.19015v1 Announce Type: new Abstract: Real measurements are too limited to train an accurate indoor pathloss predictor that works across a wide range of buildings. Large-scale synthetic pretraining offers a way forward, but real building layouts are also scarce, and acc…
