Shared Randomness in Locally Checkable Problems: The Role of Computational Assumptions
Shared randomness is a valuable resource in distributed computing, but what happens when the shared random string can affect the inputs to the system? Consider the class of distributed graph problems where the correctness of solutions can be checked locally, known as...
L3: Integrierte DIMM-PIM-Architektur und -Koordination für skalierbare Langkontext-LLM-Inferenz
Große Sprachmodelle (LLMs) increasingly require processing long text sequences, but GPU memory limitations force difficult trade-offs between memory capacity and bandwidth. While HBM-based acceleration offers high bandwidth, its capacity remains constrained. Offloading data to host-side DIMMs improves capacity but introduces costly...
Ein maschineller Lernansatz zum Entrauschen und Upsampling von HRTFs
Die Nachfrage nach realistischem, virtuellem, immersivem Audio wächst weiter, with Head-Related Transfer Functions (HRTFs) eine Schlüsselrolle spielen. HRTFs capture how sound reaches our ears, reflecting unique anatomical features and enhancing spatial perception. It has been shown that personalized HRTFs improve...
RGB-D-Tracking über hierarchische Modalitätsaggregation und -verteilung Netzwerk
The integration of dual-modal features has been pivotal in advancing RGB-Depth (RGB-D) Verfolgung. Jedoch, current trackers are less efficient and focus solely on single-level features, resulting in weaker robustness in fusion and slower speeds that fail to meet the demands of real-world...
EuGH: Eine zweistufige Datenaktualisierungsmethode für eine Erasure-Coded-Cluster-Datei System
Im Vergleich zu replikationsbasierten Speichersystemen, erasure-coded storage incurs significantly higher overhead during data updates. Um dieses Problem anzugehen, Verschiedene Paritätsprotokollierungsmethoden haben sich bewährt- gestellt. Trotzdem, due to the long update path and substantial amount of random I/O involved in erasure...
Dynamische Eichinvarianz der statistischen Mechanik
We investigate gauge invariance against phase space shifting in nonequilibrium systems, as represented by time-dependent many-body Hamiltonians that drive an initial ensemble out of thermal equilibrium. The theory gives rise to gauge correlation functions that characterize spatial and temporal inhomogeneity with microscopic...
Interpretierbare nichtlineare Dimensionsreduktion mithilfe von Gauß gewichtete lineare Transformation
Dimensionality reduction techniques are fundamental for analyzing and visualizing high-dimensional data. With established methods like t-SNE and PCA presenting a trade-off between representational power and interpretability. This paper introduces a novel approach that bridges this gap by combining the interpretability of linear...
SAPO-RL: Sequentielle Aktuatorplatzierungsoptimierung für Rumpf Zusammenbau durch Reinforcement Learning
Precise assembly of composite fuselages is critical for aircraft assembly to meet the ultra-high precision requirements. Due to dimensional variations, there is a gap when two fuselage assemble. In practice, actuators are required to adjust fuselage dimensions by applying forces to specific...
Von der Oberflächenrauheit bis zur Kraterbildung im 2D-Mehrmaßstab Simulation der Ultrakurzpulslaserablation
Die Oberflächenrauheit spielt bei der Ultrakurzpulslaserablation eine entscheidende Rolle, insbesondere für industrielle Anwendungen mit Burst-Modus-Betrieb, Multipuls-Laserbearbeitung, and the generation of laser-induced periodic surface structures. Somit, we address the impact of surface roughness on the resulting laser...
Zeitaufgelöste Dynamik von GaN-Wellenleiterpolaritonen
We implement a new experimental approach to directly measure the lifetime of guided polaritons arising from the strong-coupling of GaN excitons and the guided photonic modes of a slab waveguide. Verwendung eines Fourier-Bildgebungsaufbaus, kombiniert mit einer räumlichen Filterung der Emission,...
