Forecast with Forecasts: Diversity Matters
Yanfei Kang, Wei Cao, Fotios Petropoulos +1
Forecast combinations have been widely applied in the last few decades to improve forecasting. Estimating optimal weights that can outperform simple averages is not always an easy…
UAV LiDAR Point Cloud Segmentation of A Stack Interchange with Deep Neural Networks
Weikai Tan, Dedong Zhang, Lingfei Ma +3
Stack interchanges are essential components of transportation systems. Mobile laser scanning (MLS) systems have been widely used in road infrastructure mapping, but accurate mappin…
Cross-Supervised Joint-Event-Extraction with Heterogeneous Information Networks
Yue Wang, Zhuo Xu, Lu Bai +5
Joint-event-extraction, which extracts structural information (i.e., entities or triggers of events) from unstructured real-world corpora, has attracted more and more research atte…
Convergence rate of EM algorithm for SDEs under integrability condition
Jianhai Bao, Xing Huang, Shao-Qin Zhang
In this paper, by employing Gaussian type estimate of heat kernel, we establish Krylov's estimate and Khasminskill's estimate for EM algorithm. As applications, by taking Zvonkin's…
TCI for SDEs with irregular drifts
Yongqiang Suo, Chenggui Yuan, Shao-Qin Zhang
We obtain for stochastic differential equations with Dini continuous drift and stochastic differential equations with singular coefficients.
Distributed ARIMA Models for Ultra-long Time Series
Xiaoqian Wang, Yanfei Kang, Rob J Hyndman +1
Providing forecasts for ultra-long time series plays a vital role in various activities, such as investment decisions, industrial production arrangements, and farm management. This…
Equilibrium states of intermediate entropies
Peng Sun
We explore an approach to the conjecture of Katok on intermediate entropies that based on uniqueness of equilibrium states, provided the entropy function is upper semi-continuous.…
Weak convergence of Euler scheme for SDEs with singular drift
Yongqiang Suo, Chenggui Yuan, Shao-Qin Zhang
In this paper, we investigate the weak convergence rate of Euler-Maruyama's approximation for stochastic differential equations with irregular drifts. Explicit weak convergence rat…
Input Perturbation: A New Paradigm between Central and Local Differential Privacy
Yilin Kang, Yong Liu, Ben Niu +3
Traditionally, there are two models on differential privacy: the central model and the local model. The central model focuses on the machine learning model and the local model focu…
Exponential contraction in Wasserstein distance on static and evolving manifolds
Li-Juan Cheng, Anton Thalmaier, Shao-Qin Zhang
In this article, exponential contraction in Wasserstein distance for heat semigroups of diffusion processes on Riemannian manifolds is established under curvature conditions where…
Communication-Efficient Distributed Estimator for Generalized Linear Models with a Diverging Number of Covariates
Ping Zhou, Zhen Yu, Jingyi Ma +2
Distributed statistical inference has recently attracted immense attention. The asymptotic efficiency of the maximum likelihood estimator (MLE), the one-step MLE, and the aggregate…
