This paper shows that the performance of a Gaussian Mixture Model using a Universal Background Model (GMM-UBM) speaker verification (SV) system can be further improved by combining it with threshold a...
High-dimensional ARMA model identification and its application to healthcare picture smoothing using a forgetting factor
N-dimensional ARMA Model Forgetting factor

2010/9/21
In this paper a set of formulations of an N-dimensional (ND) autoregressive-moving average (ARMA) model identification method, and a two-dimensional (2D) forgetting factor approach in time-series mode...
Identification of a two-dimensional autoregressive oving average model for image signal processing
Two-dimensional ARMA Model Identification
font style='font-size:12px;'>
2010/9/14
A two-dimensional (2D) autoregressive-moving average (ARMA) model for image processing has been developed. An optimum estimation and prediction approach based on this modelling has been simulated. The...

From some measured data on the boundary of a domain in two dimensions, we get the unknown conductivity coefficient in the whole domain by applying Backus-Gilbert method on some integral identity. Prac...
Note on sparsity in signal recovery and in matrix identification
Sparse signal recovery compressed sensing Basis Pursuit time-frequency shifts
