Modeling and learning of brain activity patterns represent a huge challenge to the brain-computer interface (BCI) based on electroencephalography (EEG). Many existing methods estimate uncorrelated instantaneous demixing EEG signals classify multiclass motor imagery (MI). However, condition uncorrelation does not hold true in practice, because regions work with partial or complete collaboration. This proposes novel method, termed as common Bayesian network (CBN), discriminate MI signals....
In multicell multiuser massive multi-input multi-output (MIMO) systems, pilot contamination degrades the uplink (UL) channel estimation performance. To mitigate effect of contamination, we propose a semiblind method that does not require cell cooperation or statistical information channels. proposed method, first sequentially estimate UL data from different users in target cell. do that, for each user, solve constrained minimization problem to obtain an extracting vector and then use it...
This letter proposes a low-complexity deep-learning-based direction-of-arrival (DOA) estimation method for hybrid massive multiple-input multiple-output (MIMO) system with uniform circular array at the base station. In proposed method, we first input received signal vector into some small deep feedforward networks that are trained offline. Based on outputs of networks, then generate set candidate angles. By selecting optimal one from all angles, finally obtain DOA estimation. Simulation...
Melanoma is considered one of the most lethal skin cancers. However, lesion classification based on deep learning diagnostic techniques a challenging task owing to insufficiency labeled images and intraclass-imbalanced datasets. It thus necessary utilize data augmentation methods generative adversarial networks (GANs) assist help dermatologists reach more accurate decisions. Moreover, insufficient samples can cause low accuracy in model by using medical diagnosis reduce classification. To...
Seed deterioration is poorly understood and remains an active area for research. Seeds of elm (Ulmus pumila L.) were aged at 37 °C above water [controlled treatment (CDT)] various lengths time to assess programmed cell death (PCD) reactive oxygen species (ROS) product in embryonic tissues during a 5 d period. The hallmarks PCD identified the seeds CDT including TUNEL experiments, DNA laddering, cytochrome c (cyt c) leakage enzymatic activities. These analyses indicated that occurred...
We propose a simple sparse channel estimation and tracking method for orthogonal frequency-division multiplexing (OFDM) systems based on dynamic parametric model, where the is parameterized by small number of distinct paths, each characterized path delay gain, all parameters are time varying. In proposed method, we adaptively choose grid estimate iteratively. To further reduce complexity, also algorithm fact that changes in delays over few adjacent OFDM symbols. After physical estimated,...
In orthogonal frequency division multiplexing (OFDM) systems, since virtual subcarriers are not used for transmission, approach of conventional uniformly placed pilot tones is applicable in some situations. this letter, based on nonuniform tone placement, we derive optimal sequences, which can achieve the minimum mean square error least squares estimate multiple-input multiple-output (MIMO) OFDM systems. Simulation results demonstrate effectiveness proposed approach.
This short note presents the derivation of a new priori estimate for Oldroyd-B model.Such an may provide useful information when investigating long-time behaviour macro-macro models, and stability numerical schemes.We show how this can be used as guideline to derive estimates other macroscopic like FENE-P model.
The quest for enhancing the interpretability of neural networks has become a prominent focus in recent research endeavors. Prototype-based have emerged as promising avenue imbuing models with by gauging similarity between image components and category prototypes to inform decision-making. However, these face challenges they share activations during both inference explanation processes, creating tradeoff accuracy interpretability. To address this issue ensure that network achieves high robust...
This letter is concerned with the downlink channel estimation in frequency division duplex (FDD) massive multiple-input multiple-output (MIMO) system.

Uncertainty quantification in time series prediction is challenging due to the temporal dependence and distribution shift on sequential data. Conformal inference provides a pivotal flexible instrument for assessing uncertainty of machine learning models through sets. Recently, online conformal methods updated thresholds sets by performing gradient descent sequence quantile loss functions. A drawback such that they only use information revealed non-conformity scores via miscoverage indicators...
