Gamma factors for Asai representations of
Shih-Yu Chen, Yao Cheng, Isao Ishikawa
Let be a quadratic semisimple extension of a local field of characteristic zero. We determine explicit relation between gamma factors for Asai representations of $R_{E/F}{\…
Metric on Nonlinear Dynamical Systems with Perron-Frobenius Operators
Isao Ishikawa, Keisuke Fujii, Masahiro Ikeda +2
The development of a metric for structural data is a long-term problem in pattern recognition and machine learning. In this paper, we develop a general metric for comparing nonline…
The global optimum of shallow neural network is attained by ridgelet transform
Sho Sonoda, Isao Ishikawa, Masahiro Ikeda +4
We prove that the global minimum of the backpropagation (BP) training problem of neural networks with an arbitrary nonlinear activation is given by the ridgelet transform. A series…
