Noesis: Bidirectional Graph-RAG with Adaptive Parallelism and Cross-Knowledge-Base Semantic Discovery
Nicola Cogotti
Retrieval-Augmented Generation over knowledge graphs (Graph-RAG) has emerged as a powerful paradigm for grounding large language models in domain-specific corpora. However, existin…
Parallel approximation of the exponential of Hermitian matrices
Frédéric Hecht, Sidi-Mahmoud Kaber, Lucas Perrin +2
In this work, we consider a rational approximation of the exponential function to design an algorithm for computing matrix exponential in the Hermitian case. Using partial fraction…
A Directional Equispaced interpolation-based Fast Multipole Method for oscillatory kernels
Igor Chollet, Xavier Claeys, Pierre Fortin +1
Fast Multipole Methods (FMMs) based on the oscillatory Helmholtz kernel can reduce the cost of solving N-body problems arising from Boundary Integral Equations (BIEs) in acoustic o…
High-frequency cyclicity in the Mediterranean Messinian evaporites: evidence for solar-lunar climate forcing
Vinicio Manzi, Rocco Gennari, Stefano Lugli +3
The deposition of varved sedimentary sequences is usually controlled by climate conditions. The study of two Late Miocene evaporite successions (one halite and the other gypsum) co…
