Vom menschlichen Gedächtnis zum KI-Gedächtnis: Eine Übersicht über Gedächtnismechanismen in der Ära von LLMs
Erinnerung ist der Prozess der Kodierung, Speicherung, und Abrufen von Informationen, Menschen ermöglichen, Erfahrungen zu behalten, Wissen, Fähigkeiten, und Fakten im Laufe der Zeit, and serving as the foundation for growth and effective interaction with the world. It plays a crucial role in shaping our...
Ein UAV-gestütztes Digital Twin Framework für IoT-Netzwerke mit hoher Genauigkeit und Synchronisation
With the continued growth of its core technologies, including the Internet of Things (IoT), artificial intelligence (AI), Big Data and data analytics, and edge computing, digital twin (DT) technology has witnessed a significant increase in industrial applications, helping the industry become more...
Vorhersage des Fehlerschicksals in großen Open-Source-Software-Repositories durch Stimmungsanalyse und BERT-Themenmodellierung
Diese Studie untersucht einen neuartigen Ansatz zur Vorhersage wichtiger fehlerbezogener Ergebnisse, einschließlich der Zeit bis zur Lösung, Zeit zu reparieren, und endgültiger Status eines Fehlers, unter Verwendung von Daten aus dem Bugzilla Eclipse Project. Speziell, we leverage features available before a bug is resolved...
Wohlgestelltheit des Transports normaler Ströme durch Zeitabhängigkeit Vektorfelder
We prove existence and uniqueness for the transport equation for currents (Geometric Transport Equation) when the driving vector field is time-dependent, Lipschitz in space and merely integrable in time. This extends previous work where well-posedness was shown in the case of a...
Efficient Discovery of Motif Transition Process for Large-Scale Temporal Graphs
Understanding the dynamic transition of motifs in temporal graphs is essential for revealing how graph structures evolve over time, identifying critical patterns, and predicting future behaviors, yet existing methods often focus on predefined motifs, limiting their ability to comprehensively capture transitions and...
The effects of transport processes on the bulk composition of the first generation of planetesimals interior to the water iceline
The CHNOS elemental budgets of rocky planets are crucial for their structure, evolution and potential chemical habitability. It is unclear how the nonlocal disk processes affecting dust in planet-forming disks affect the CHNOS elemental budgets of nascent planets both inside and outside...
W-PCA Based Gradient-Free Proxy for Efficient Search of Lightweight Language Models
The demand for efficient natural language processing (NLP) systems has led to the development of lightweight language models. Previous work in this area has primarily focused on manual design or training-based neural architecture search (NAS) Methoden. Kürzlich, zero-shot NAS methods have been...
Modeling and Forecasting Realized Volatility with Multivariate Fractional Brownian Motion
A multivariate fractional Brownian motion (mfBm) with component-wise Hurst exponents is used to model and forecast realized volatility. We investigate the interplay between correlation coefficients and Hurst exponents and propose a novel estimation method for all model parameters, establishing consistency and asymptotic...
SN 2023vbg: A Type IIn Supernova Resembling SN 2009ip, with a Long-Duration Precursor and Early-Time Bump
Type IIn supernovae (SNe) resembling SN 2009ip (09ip-like SNe) originate from the interaction between circumstellar material (CSM) and the ejecta. This subclass not only shares similar observational properties around the maximum, but is commonly characterized by a long duration precursor before its...
Infinitely many collisions between a recurrent simple random walk and arbitrary many transient random walks in a subballistic random environment
We consider $d$ random walks $\big(S_n^{(J)}\big)_{n\in\mathbb{N}}$, $1\leq j \leq d$, in the same random environment $\omega$ in $\mathbb{Z}$, and a recurrent simple random walk $(Z_n)_{n\in\mathbb{N}}$ on $\mathbb{Z}$. We assume that, conditionally on the environment $\omega$, all the random walks are independent and...
