Deep Switching Auto-Regressive Factorization: Application to Time Series Forecasting

open access: yes, 2021
We introduce deep switching auto-regressive factorization (DSARF), a deep generative model for spatio-temporal data with the capability to unravel recurring patterns in the data and perform robust short- and long-term predictions. Similar to other factor

Bank Lending (Credit) Channel of Monetary Transmission Mechanism

open access: yesJournal of Business and Social Review in Emerging Economies, 2018
The significance of channel of bank lending for the process of transmission of monetary policy is examined employing the model of ARDL (Auto-regressive-distributed lag).

Compound digital filter

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2014
This paper describes the identification by the compound digital filter with two estimators involved in the Kalman filter, the first corresponds to stochastic gradient describing the transition function and the second obtains the innovation process gain ...

Prognosis of Bearing Degradation Using Gradient Variable Forgetting Factor RLS Combined With Time Series Model

open access: yesIEEE Access, 2018
Rolling element bearing is a critical component in many mechanical systems in view of its critical functionality. One of the major issues industries face today is the failure of bearings, which results in catastrophic consequences.

Identifikasi Pemodelan Matematis Robot Wall Following

open access: yesJurnal Nasional Teknik Elektro dan Teknologi Informasi, 2018
This paper describes the process to obtain a mathematical model of a wall following robot. A mathematical modeling is carried out as an effort in determining Proportional, Integral, and Derivative (PID) controller parameters using analytic tuning.

Prediction of weakly locally stationary processes by auto-regression

open access: yesLatin American Journal of Probability and Mathematical Statistics, 2018
In this contribution we introduce weakly locally stationary time series through the local approximation of the non-stationary covariance structure by a stationary one. This allows us to define autoregression coefficients in a non-stationary context, which, in the particular case of a locally stationary Time Varying Autoregressive (TVAR ...

Classification and retrieval of traffic video using auto-regressive stochastic processes [PDF]

open access: yesIEEE Proceedings. Intelligent Vehicles Symposium, 2005., 2005
We propose to model the traffic flow in a video using a holistic generative model that does not require segmentation or tracking. In particular, we adopt the dynamic texture model, an auto-regressive stochastic process, which encodes the appearance and the underlying motion separately into two probability distributions.
