We propose a model that interpolates between quantum walks and persistent (correlated) random walks using one parameter on the one-dimensional lattice. We show that the limit distribution is described ...

GAT-RWOS: Graph Attention-Guided Random Walk Oversampling for Imbalanced Data Classification. A graph attention-guided oversampling method for imbalanced data classification using GAT and random walks ...

Random walk theory proposes that stock prices move unpredictably, making it impossible to predict future movements based solely on past trends. This financial theory, first popularized by economist ...

We primarily provide several estimates for the heat kernel defined on the 2-dimensional simple random walk. Additionally, we offer an estimate for the heat kernel on high-dimensional random walks, ...

Purpose: To evaluate the efficacy of high b-value diffusion-weighted imaging (DWI) with a continuous-time random-walk (CTRW) diffusion model in determining the pathological grade and variant histology ...

The random walk theorem, first presented by French mathematician Louis Bachelier in 1900 and then expanded upon by economist Burton Malkiel in his 1973 book A Random Walk Down Wall Street, asserts ...

Abstract: Graphs are commonly used in various applications such as online social networks (OSNs), E-commerce systems and social recommender systems. Random walk ...
