ML-based approach to classification and generation of structured light propagation in turbulent media
Aokun Wang, Anjali Nair, Zhongjian Wang +1
We study the classification task of structured-light beams after propagation through a random turbulent medium. The received speckle patterns are generated by numerical simulation…
Frequency-Domain Latent Attention Gating for Cross-Domain Token Aggregation
Kewei Li, Rongying Zhang, Xueli Wang +5
Token aggregation is a common bottleneck in models that map token representations to sample-level predictions, yet most pooling methods operate only in the original token domain. W…
Inverse scattering for waveguides in topological insulators
Guillaume Bal, Xixian Wang, Zhongjian Wang
This paper concerns the inverse scattering problem of a topologically non-trivial waveguide separating two-dimensional topological insulators. We consider the specific model of a D…
Wasserstein Bounds for generative diffusion models with Gaussian tail targets
Xixian Wang, Zhongjian Wang
We present an estimate of the Wasserstein distance between the data distribution and the generation of score-based generative models. The sampling complexity with respect to dimens…
