Attention Mechanism in Randomized Time Warping
Yutaro Hiraoka, Kazuya Okamura, Kota Suto +1
This paper reveals that we can interpret the fundamental function of Randomized Time Warping (RTW) as a type of self-attention mechanism, a core technology of Transformers in motio…
Reexamination of the hierarchy problem from a novel geometric perspective
Hirofumi Sakuma, Izumi Ojima, Kazuya Okamura
A lucid interpretation of the longstanding hierarchy problem is proposed based on the unconventional model of the universe recently proposed by the authors. Our heuristic cosmologi…
Conserved relativistic Ertel's current generating the vortical and thermodynamic aspects of spacetime
Hirofumi Sakuma, Izumi Ojima, Hayato Saigo +1
Motivated by Aoki et al.'s recent research on conserved charges and entropy current, we investigated the conservation of relativistic Ertel's current, which has received little att…
Linear simultaneous measurements of position and momentum with minimum error-trade-off in each minimum uncertainty state
Kazuya Okamura
So-called quantum limits and their achievement are important themes in physics. Heisenberg's uncertainty relations are the most famous of them but are not universally valid and vio…
Linear position measurements with minimum error-disturbance in each minimum uncertainty state
Kazuya Okamura
In quantum theory, measuring process is an important physical process; it is a quantum description of the interaction between the system of interest and the measuring device. Error…
Universally valid uncertainty relations in general quantum systems
Kazuya Okamura, Masanao Ozawa
We study universally valid uncertainty relations in general quantum systems described by general -finite von Neumann algebras to foster developing quantitative analysis in quant…
