TWIG: A Time-Causal Wavelet Operator for Autoregressive Forecasting on Irregular Graphs
Subashree Venkatasubramanian, David A. Barajas-Solano, Chuyang Liu +2
We introduce TWIG (Time-Causal Wavelet Operator for Irregular Graphs), a graph-native neural operator for autoregressive surrogate modeling on static irregular graphs. TWIG transfo…

Variational Encoder-Decoders for Learning Latent Representations of Physical Systems
Subashree Venkatasubramanian, David A. Barajas-Solano
We present a deep-learning Variational Encoder-Decoder (VED) framework for learning data-driven low-dimensional representations of the relationship between high-dimensional paramet…
