Platonic Projection Structures: Operator-Induced Observability in Representation Learning
Kazuo Ishii, Bishnu Prasad Gautam, Jieling Wu +2
We characterize observability in representation learning through Platonic Projection Structures (PPS), an operator-theoretic framework for analyzing representation accessibility un…
Confidence Intervals for Extinction Risk: Validating Population Viability Analysis with Limited Data
Hiroshi Hakoyama
Quantitative assessment of extinction risk requires confidence intervals (CIs) that remain informative with limited data. Their usefulness has long been debated because short obser…
Development of a near-infrared wide-field integral field unit by ultra-precision diamond cutting
Kosuke Kushibiki, Shinobu Ozaki, Masahiro Takeda +17
Integral Field Spectroscopy (IFS) is an observational method to obtain spatially resolved spectra over a specific field of view (FoV) in a single exposure. In recent years, near-in…
Higher Courant-Dorfman algebras and associated higher Poisson vertex algebras
Ryo Hayami
In this paper, we consider a notion of a higher version of the relation between Courant-Dorfman algebras and Poisson vertex algebras. We define a higher Courant-Dorfman algebra, an…
A new off-point-less observing method for millimeter and submillimeter spectroscopy with a frequency-modulating local oscillator (FMLO)
Akio Taniguchi, Yoichi Tamura, Kotaro Kohno +6
We propose a new observing method for single-dish millimeter and submillimeter spectroscopy using a heterodyne receiver equipped with a frequency-modulating local oscillator (FMLO)…
