On network-error correcting convolutional codes under the BSC edge error model [PDF]

open access: yes2010 IEEE International Symposium on Information Theory, 2010
Convolutional network-error correcting codes (CNECCs) are known to provide error correcting capability in acyclic instantaneous networks within the network coding paradigm under small field size conditions. In this work, we investigate the performance of CNECCs under the error model of the network where the edges are assumed to be statistically ...

Precipitation Forecast Correction in South China Based on SVD and Machine Learning

open access: yes应用气象学报, 2022
Precipitation can be induced by various weather systems and a series of complex physical processes, so its prediction is relatively difficult in weather forecasting. Due to the limitation of numerical model, the prediction error is inevitable.

Asymmetric Error Correction Models for the Oil-Gasoline Price Relationship [PDF]

open access: yesSSRN Electronic Journal, 2005
The existing literature on price asymmetries does not systematically investigate the sensitivity of the empirical results to the choice of a particular econometric specification. This paper fills this gap by providing a detailed comparison of the three most popular models designed to describe asymmetric price behaviour, namely asymmetric ECM ...

Econometrical Modelling of Profit Tax Revenue

open access: yesNonlinear Analysis, 2007
The aim of this article is to present a forecast of budget revenue from the profit tax using econometric models. The set of applied models has to be reduced to very simple models due to short time series used.

The Vector Error Correction Index Model: Representation, Estimation and Identification

open access: yesSSRN Electronic Journal, 2023
SummaryThis paper extends the multivariate index autoregressive model to the case of cointegrated time series of order (1,1). In this new modelling, namely the vector error-correction index model (VECIM), the first differences of series are driven by some linear combinations of the variables, namely the indexes. When the indexes are significantly fewer

Experimental test of the birdsong error-correction model [PDF]

open access: yesProceedings of the National Academy of Sciences, 2004
Adult zebra finches require auditory feedback to maintain their songs. It has been proposed that the lateral magnocellular nucleus of the anterior nidopallium (LMAN) mediates song plasticity based on auditory feedback. In this model, neurons in LMAN, tuned to the spectral and temporal properties of the bird's own song (BOS), are thought to compute the ...

Chinese Grammatical Error Correction Based on Grammatical Knowledge Enhancement [PDF]

open access: yesJisuanji gongcheng, 2023
The aim of grammatical error correction is to judge whether natural language texts contain grammatical errors, to correct them. In recent years, with the rapid development of pre-trained language models, methods based on such models have been widely used
