A Mean Field Ansatz for Zero-Shot Weight Transfer
Xingyuan Chen, Wenwei Kuang, Lei Deng +3
The pre-training cost of large language models (LLMs) is prohibitive. One cutting-edge approach to reduce the cost is zero-shot weight transfer, also known as model growth for some…

Improved weak convergence for the long time simulation of Mean-field Langevin equations
Xingyuan Chen, Goncalo dos Reis, Wolfgang Stockinger +1
We study the weak convergence behaviour of the Leimkuhler--Matthews method, a non-Markovian Euler-type scheme with the same computational cost as the Euler scheme, for the approxim…

An iterative method for Helmholtz boundary value problems arising in wave propagation
Francisco Bernal, Xingyuan Chen, Goncalo dos Reis
The complex Helmholtz equation (where ) is a mainstay of computational wave simulation. Despite its apparent simplici…
