The paper introduces a hybrid quantum-classical framework enhancing Quantum Physics-Informed Neural Networks (QPINNs) with adaptive collocation point sampling and loss-aware attention for solving differential equations, achieving significant accuracy improvements in fluid dynamics and reaction-diffusion benchmarks.
This paper extends Pearl's structural causal model framework by introducing causal zeros and causal differential equations to handle symmetric constraints and feedback cycles, which are not allowed in directed acyclic graphs.
Introduces PI-Splines, a structured spline-based architecture for physics-informed learning that parametrizes unknown fields with trainable B-spline coefficients, providing compact support, analytical derivatives, and strong boundary condition enforcement, demonstrated as a competitive alternative to neural network-based methods.
This paper introduces Branched Neural Rough Differential Equations, a method for learning manifold and Itô dynamics by combining rough path theory with neural networks, enabling the modeling of complex stochastic and geometric structures.
