Saddle-to-saddle dynamics in diagonal linear networks* [PDF]
Journal of Statistical Mechanics: Theory and Experiment, 2023 Abstract In this paper we fully describe the trajectory of gradient flow over two-layer diagonal linear networks for the regression setting in the limit of vanishing initialisation. We show that the limiting flow successively jumps from a saddle of the training loss to another until reaching the minimum

SGD learning on neural networks: leap complexity and saddle-to-saddle dynamics [PDF]
Annual Conference Computational Learning Theory, 2023 We investigate the time complexity of SGD learning on fully-connected neural networks with isotropic data. We put forward a complexity measure -- the leap -- which measures how"hierarchical"target functions are.

Krylov complexity in saddle-dominated scrambling [PDF]
Journal of High Energy Physics, 2022 In semi-classical systems, the exponential growth of the out-of-time-order correlator (OTOC) is believed to be the hallmark of quantum chaos. However, on several occasions, it has been argued that, even in integrable systems, OTOC can grow exponentially ...

Electronic instabilities of kagome metals: Saddle points and Landau theory [PDF]
Physical review B, 2021 We study electronic instabilities of a kagomé metal with a Fermi energy close to saddle points at the hexagonal Brillouin zone face centers.

Life, 2021 Human straight-legged bipedalism represents one of the earliest events in the evolutionary split between humans (Homo spp.) and chimpanzees (Pan spp.), although its selective basis is a mystery. A carrying-related hypothesis has recently been proposed in

Women's cycling and motorcycling from the point of view of jurisprudence and law [PDF]
فقه و حقوق خانواده, 2023 In the past, humans used animals for transportation, however, in narrative sources, women riding the saddle is condemned. Considering that nowadays cycling and motorcycling have become popular among women and no independent research has been written in ...

Impact of Weight Carriage on Joint Kinematics in Asian Elephants Used for Riding
Animals, 2021 Background: Elephants in Thailand have changed their roles from working in the logging industry to tourism over the past two decades. In 2020, there were approximately 2700 captive elephants participating in activities such as riding and trekking. During
