چکیده

SUMMARY Denoising and onset time picking of signals are essential before extracting source information from collected seismic/microseismic data. We proposed an advanced deep dual-tasking network (DDTN) that integrates these two procedures sequentially to achieve the optimal performance. Two homo-structured encoder–decoder networks with specially designed structures parameters connected in series for handling denoising detection microseismic signals. Based on similarity data types, output will be imported into obtain labels signal duration. The duration can completed integrated way, where denoised improve accuracy picking. Results show method has a good performance contain various types intensities noise. Compared existing methods, DDTN removes noise minor waveform distortion. It is ideal recovering while maintaining capacity when signal-to-noise ratio low. that, second detect more accurate thus time. great potential extended study exploration seismology earthquakes.

A New Approach for Investigating the Complexity of Short Term EEG Signal Based on Neural Network

 Background and purpose: The nonlinear quality of electroencephalography (EEG), like other irregular signals, can be quantified. Some of these values, such as Lyapunovchr('39')s representative, study the signal path divergence and some quantifiers need to reconstruct the signal path but some do not. However, all of these quantifiers require a long signal to quantify the signal complexity. Mate...

A conjugate gradient based method for Decision Neural Network training

Decision Neural Network is a new approach for solving multi-objective decision-making problems based on artificial neural networks. Using inaccurate evaluation data, network training has improved and the number of educational data sets has decreased. The available training method is based on the gradient decent method (BP). One of its limitations is related to its convergence speed. Therefore,...
