A Linear Parameter-Varying Hammerstein Model for Dynamic Modeling of WPT Systems

Abstract: To better handle nonlinearities in the dynamic modeling of wireless power transfer systems, a linear parameter-varying (LPV) Hammerstein model is derived, along with a method to identify the ...

Beyond the lakehouse: Fundamental's NEXUS bypasses manual ETL with a native foundation model for tabular data

Emerging from stealth, the company is debuting NEXUS, a Large Tabular Model (LTM) designed to treat business data not as a simple sequence of words, but as a complex web of non-linear relationships.
