Feature Resemblance: Towards a Theoretical Understanding of Analogical Reasoning in Transformers

ICML 2026poster

Understanding reasoning in large language models is complicated by evaluations that conflate multiple reasoning types. We isolate analogical reasoning (inferring shared properties between entities based on known similarities) and analyze its emergence in transformers. We theoretically prove three ke…

GAGA: Gaussianity-Aware Gaussian Approximation for Efficient 3D Molecular Generation

ICLR 2026poster

Gaussian Probability Path based Generative Models (GPPGMs) generate data by reversing a stochastic process that progressively corrupts samples with Gaussian noise. Despite state-of-the-art results in 3D molecular generation, their deployment is hindered by the high cost of long generative trajectori…

Discretization-invariance? On the Discretization Mismatch Errors in Neural Operators

ICLR 2025poster

In recent years, neural operators have emerged as a prominent approach for learning mappings between function spaces, such as the solution operators of parametric PDEs. A notable example is the Fourier Neural Operator (FNO), which models the integral kernel as a convolution operator and uses the Con…
