ODEBrain: Continuous-Time EEG Graph for Modeling Dynamic Brain Networks

ICLR 2026poster

Modeling neural population dynamics is crucial for foundational neuroscientific research and various clinical applications. Conventional latent variable methods typically model continuous brain dynamics through discretizing time with recurrent architecture, which necessarily results in compounded cu…

PHyCLIP: $\ell_1$-Product of Hyperbolic Factors Unifies Hierarchy and Compositionality in Vision-Language Representation Learning

ICLR 2026poster

Vision-language models have achieved remarkable success in multi-modal representation learning from large-scale pairs of visual scenes and linguistic descriptions. However, they still struggle to simultaneously express two distinct types of semantic structures: the hierarchy within a concept family…

Number Theoretic Accelerated Learning of Physics-Informed Neural Networks

AAAI 2025technical

Physics-informed neural networks solve partial differential equations by training neural networks. Since this method approximates infinite-dimensional PDE solutions with finite collocation points, minimizing discretization errors by selecting suitable points is essential for accelerating the learnin…

Poisson-Dirac Neural Networks for Modeling Coupled Dynamical Systems across Domains

ICLR 2025poster

Deep learning has achieved great success in modeling dynamical systems, providing data-driven simulators to predict complex phenomena, even without known governing equations. However, existing models have two major limitations: their narrow focus on mechanical systems and their tendency to treat sys…

Predicated Diffusion: Predicate Logic-Based Attention Guidance for Text-to-Image Diffusion Models

CVPR 2024highlight

Diffusion models have achieved remarkable success in generating high-quality diverse and creative images. However in text-based image generation they often struggle to accurately capture the intended meaning of the text. For instance a specified object might not be generated or an adjective might in…

Deep Curvilinear Editing: Commutative and Nonlinear Image Manipulation for Pretrained Deep Generative Model

CVPR 2023poster

Semantic editing of images is the fundamental goal of computer vision. Although deep learning methods, such as generative adversarial networks (GANs), are capable of producing high-quality images, they often do not have an inherent way of editing generated images semantically. Recent studies have in…

FINDE: Neural Differential Equations for Finding and Preserving Invariant Quantities

ICLR 2023poster

Many real-world dynamical systems are associated with first integrals (a.k.a. invariant quantities), which are quantities that remain unchanged over time. The discovery and understanding of first integrals are fundamental and important topics both in the natural sciences and in industrial applicatio…

KAM Theory Meets Statistical Learning Theory: Hamiltonian Neural Networks with Non-zero Training Loss

AAAI 2022technical

Many physical phenomena are described by Hamiltonian mechanics using an energy function (Hamiltonian). Recently, the Hamiltonian neural network, which approximates the Hamiltonian by a neural network, and its extensions have attracted much attention. This is a very powerful method, but theoretical s…

Neural Symplectic Form: Learning Hamiltonian Equations on General Coordinate Systems

NeurIPS 2021spotlight

In recent years, substantial research on the methods for learning Hamiltonian equations has been conducted. Although these approaches are very promising, the commonly used representation of the Hamilton equation uses the generalized momenta, which are generally unknown. Therefore, the training data…

Symplectic Adjoint Method for Exact Gradient of Neural ODE with Minimal Memory

NeurIPS 2021poster

A neural network model of a differential equation, namely neural ODE, has enabled the learning of continuous-time dynamical systems and probabilistic distributions with high accuracy. The neural ODE uses the same network repeatedly during a numerical integration. The memory consumption of the backpr…
