A novel machine learning approach to analyzing geospatial vessel patterns using AIS data

open access: yesGIScience & Remote Sensing, 2022
In the maritime environment, the Automatic Identification System (AIS) contains information related to vessel trajectories that can be used to detect unusual maritime occurrences and maritime traffic patterns.

Self-Generated In-Context Learning: Leveraging Auto-regressive Language Models as a Demonstration Generator [PDF]

open access: yesarXiv.org, 2022
Large-scale pre-trained language models (PLMs) are well-known for being capable of solving a task simply by conditioning a few input-label pairs dubbed demonstrations on a prompt without being explicitly tuned for the desired downstream task.

Asymmetry tests for bifurcating auto-regressive processes with missing data [PDF]

open access: yesStatistics & Probability Letters, 2012
We present symmetry tests for bifurcating autoregressive processes (BAR) when some data are missing. BAR processes typically model cell division data. Each cell can be of one of two types \emph{odd} or \emph{even}. The goal of this paper is to study the possible asymmetry between odd and even cells in a single observed lineage.

On Tail Dependence and Multifractality

open access: yesMathematics, 2020
We study whether, and if yes then how, a varying auto-correlation structure in different parts of distributions is reflected in the multifractal properties of a dynamic process.

Large-Scale Auto-Regressive Modeling Of Street Networks [PDF]

open access: yesarXiv.org, 2022
We present a novel generative method for the creation of city-scale road layouts. While the output of recent methods is limited in both size of the covered area and diversity, our framework produces large traversable graphs of high quality consisting of ...

One-Shot Bipedal Robot Dynamics Identification With a Reservoir-Based RNN

open access: yesIEEE Access, 2023
The nonlinear inverted pendulum model of a lightweight bipedal robot is identified in real-time using a reservoir-based Recurrent Neural Network (RNN). The adaptation occurs online, while a disturbance force is repeatedly applied to the robot body.

Modeling Method of Human Motion Based on Dynamic Forest Model [PDF]

open access: yesJisuanji gongcheng, 2016
Aiming at the disadvantages that the existing modeling methods of human motion cannot be applied at the general nonlinear and non-Gaussian cases,based on the Markoff model,an improved modeling method of human motion is proposed.The Markov process of ...

Effect of the COVID-19 pandemic on the number of deaths in Peru: 2017.03-2020.07

open access: yesSemestre Economico, 2021
The objective of the research is to estimate the excess deaths during the COVID-19 epidemic in Peru. The methodology used for the ARMA models with structural with a structural change in mean. In the first place, the results show that the behavior of the

Relay transmission under mobile edge computing in energy-limited networks with real-time constraints

open access: yesJournal of Algorithms & Computational Technology, 2020
For energy-limited networks with real-time constraints, long-distance transmission, complex calculations, and limited delay are problems to be faced in service applications.

Probabilistic Kernels for the Classification of Auto-Regressive Visual Processes [PDF]

open access: yes2005 IEEE Computer Society Conference on Computer Vision and Pattern Recognition (CVPR'05), 2005
We present a framework for the classification of visual processes that are best modeled with spatio-temporal autoregressive models. The new framework combines the modeling power of a family of models known as dynamic textures and the generalization guarantees, for classification, of the support vector machine classifier. This combination is achieved by
