New PIEFS framework offers physics-informed spectral representation learning

Researchers have introduced PIEFS, a novel supervised neural representation-learning framework that utilizes a modified Dirichlet energy for spectral inductive bias. This method, called Physics-Informed Eigenfunction Features with Learnable Scaling, trains scalar coordinate maps under empirical Gram orthogonality and a Dirichlet penalty with a learnable metric. Experiments on various benchmarks demonstrate PIEFS's effectiveness as a compact supervised spectral representation method, with future work focusing on optimization stability and richer metric parameterizations.
