Google Researchers Introduce An Open-Source Library in JAX for Deep Learning on Spherical Surfaces
Deep learning, a subset of machine learning, has various applications in fields such as image and speech recognition, finance, autonomous vehicles, and recommendation systems. However, when it comes to analyzing spherical signals, there are challenges that can be addressed using a planar approach.
Researchers have developed an open-source library in JAX for deep learning on spherical surfaces. This library outperforms existing methods in molecular property prediction and weather forecasting, which are typically handled by transformers and graph neural networks.
Benefits of Spherical CNNs
Spherical CNNs offer practical solutions to the challenges of sampling and robustness to rotation. They leverage spherical convolution and cross-correlation operations to provide accurate representations of spherical data. This has promising applications in medical research and climate analysis.
For molecular property prediction, spherical CNNs capture the inherent symmetries of molecular structures, where properties remain invariant to 3D rotations. In weather forecasting, atmospheric data displayed on a sphere can be effectively managed by spherical CNNs, capturing repeated patterns at various places and orientations.
Performance and Applications
The researchers’ models exceed or match traditional CNN-based neural weather models on weather forecasting benchmarks. The models accurately forecast atmospheric variables up to six hours in advance and up to three days in advance during training.
These spherical CNNs demonstrate exceptional performance across various weather forecasting scenarios, making them effective neural weather models. They have the potential to revolutionize the fields of medical research and climate analysis.
