Diffusion Language Models as Open Quantum Systems
Akinori Tanaka, Yukinao Akamatsu, Takuki Tomita +1
Diffusion language models generate text by reversing a classical diffusion process over token sequences. We show that their continuous-time forward and reverse dynamics can be embe…
Understanding Diffusion Models by Feynman's Path Integral
Yuji Hirono, Akinori Tanaka, Kenji Fukushima
Score-based diffusion models have proven effective in image generation and have gained widespread usage; however, the underlying factors contributing to the performance disparity b…
Bézier Flow: a Surface-wise Gradient Descent Method for Multi-objective Optimization
Akiyoshi Sannai, Yasunari Hikima, Ken Kobayashi +2
In this paper, we propose a strategy to construct a multi-objective optimization algorithm from a single-objective optimization algorithm by using the Bézier simplex model. Also, w…
Approximate Bayesian Computation of Bézier Simplices
Akinori Tanaka, Akiyoshi Sannai, Ken Kobayashi +1
Bézier simplex fitting algorithms have been recently proposed to approximate the Pareto set/front of multi-objective continuous optimization problems. These new methods have shown…
Self-learning Monte-Carlo for non-abelian gauge theory with dynamical fermions
Yuki Nagai, Akinori Tanaka, Akio Tomiya
In this paper, we develop the self-learning Monte-Carlo (SLMC) algorithm for non-abelian gauge theory with dynamical fermions in four dimensions to resolve the autocorrelation prob…
Discriminator optimal transport
Akinori Tanaka
Within a broad class of generative adversarial networks, we show that discriminator optimization process increases a lower bound of the dual cost function for the Wasserstein dista…
