Holographic QCD models are effective models of hadron physics that are constructed based on insights from gauge-gravity duality. The construction of these models can be approached from two directions: top-down, based on reduction from string theory, and bottom-up, based on insights from gauge-gravity duality. However, both methods have their problems. In the top-down approach, it is generally difficult to reduce to hadron physics as a low-energy effective model of QCD. The bottom-up approach, although based on the properties of QCD, requires the assumption of a simple model. In contrast, we propose a data-driven approach. In this method, we construct complex holographic models from physical quantities through spacetime emerging via deep learning based on AdS/DL and the derivation of the corresponding gravitational action. In particular, we construct the model using ρ meson spectrum data. This study opens up new possibilities for the construction and application of holographic QCD models, and could potentially provide a new way to bridge the gap between string theory and experimental facts. -[http://www-het.ph.tsukuba.ac.jp/Seminar/tsukuba-only/2023/seminar20230607_Sumimoto.pdf 2023/06/7:slides(pdf)]
