Emotion recognition based on electroencephalography (EEG) is a significant task in the brain-computer interface field. Recently, many deep learning-based emotion methods are demonstrated to outperform traditional methods. However, it remains challenging extract discriminative features for EEG recognition, and most ignore useful information channel time. This article proposes an attention-based convolutional recurrent neural network (ACRNN) more from signals improve accuracy of recognition....

Infrared and visible image fusion aims to describe the same scene from different aspects by combining complementary information of multi-modality images. The existing Generative adversarial networks (GAN) based infrared methods cannot perceive most discriminative regions, hence fail highlight typical parts in To this end, we integrate multi-scale attention mechanism into both generator discriminator GAN fuse images (AttentionFGAN). not only capture comprehensive spatial help focus on...

Recently, deep neural networks (DNNs) have been applied to emotion recognition tasks based on electroencephalography (EEG), and achieved better performance than traditional algorithms. However, DNNs still the disadvantages of too many hyperparameters lots training data. To overcome these shortcomings, in this article, we propose a method for multi-channel EEG-based using forest. First, consider effect baseline signal preprocess raw artifact-eliminated EEG with removal. Secondly, construct...

Remote photoplethysmography (rPPG) is a non-contact technique for measuring cardiac signals from facial videos. High-quality rPPG pulse are urgently demanded in many fields, such as health monitoring and emotion recognition. However, most of the existing methods can only be used to get average heart rate (HR) values due limitation inaccurate signals. In this paper, new framework based on generative adversarial network, called PulseGAN, introduced generate realistic through denoising...

Identifying the political perspective shaping way news events are discussed in media is an important and challenging task. In this paper, we highlight importance of contextualizing social information, capturing how information disseminated networks. We use Graph Convolutional Networks, a recently proposed neural architecture for representing relational to capture documents’ context. show that can be used effectively as source distant supervision, when direct supervision available, even...

Remote photoplethysmography (rPPG) is a kind of noncontact technique to measure heart rate (HR) from facial videos. As the demand for long-term health monitoring grows, rPPG attracts much attention researchers. However, performance conventional methods easily degenerated due noise interference. Recently, some deep learning-based have been introduced and they revealed good against noise. In this article, we propose new method with convolutional neural networks (CNNs) build mapping between...

Methods based on generative adversarial network (GAN) have been widely used in infrared and visible images fusion. However, these methods cannot perceive the discriminative parts of an image. Therefore, we introduce a multigrained attention module into encoder-decoder to fuse (MgAN-Fuse). The are encoded by two independent encoder networks due their diverse modalities. Then, results encoders concatenated calculate fused result decoder. To exploit features multiscale layers fully force model...

Deep learning has been successfully applied to infrared and visible image fusion due its powerful ability of feature representation. Existing most deep based methods mainly utilize pure convolution model or transformer model, which leads that the fused cannot preserve long-range dependencies (global context) local features simultaneously. To this end, we propose a convolution-guided framework for (CGTF), aims combine convolutional network dependency produce satisfactory image. In CGTF, are...
