Mitsuhiro Toriumi is a senior researcher at the Japan Agency for Marine–Earth Science and Technology (JAMSTEC) and an emeritus professor of The University of Tokyo. He is also an advisor of the National Institute of Fusion Science and was the Japan Science and Technology Agency. He was the scientific director of the Institute for Research on Earth Evolution (IFREE) in JAMSTEC from 2011 to 2013. He was a professor of complexity earth science, petrology, and structural geology at The University of Tokyo from 1991 to 2011. His research interests include metamorphic petrology, structural geology, rheology in the earth interior, global seismicity dynamics, and neural network modeling. He has published several books of earth sciences (global seismicity dynamics, data-driven science, neural network modeling of seismicity, and geochemical mechanics) in English.

Physics of Geochemical Mechanics and Deep Neural Network Modeling with Diffusion Augmentation
Mitsuhiro Toriumi
This book provides a new data augmentation method based on the local stochastic distribution patterns in natural time series data of global and regional seismicity rates and their correlated seismicity rates. The augmentation procedure is called the diffusion – denoising augmentation method from the local Gaussian distribution of segmented data of long time series. This method makes it possible to apply the deep machine learning necessary to neural network prediction...
