Objective: Accurate decoding of electroencephalogram (EEG) signals has become more significant for the brain-computer interface (BCI). Specifically, motor imagery and motor execution (MI/ME) tasks enable the control of external devices by decoding EEG signals during imagined or real movements. However, accurately decoding MI/ME signals remains a challenge due to the limited utilization of temporal information and ineffective feature selection methods. Methods: This paper introduces DMSACNN, an end-to-end deep multiscale attention convolutional neural network for MI/ME-EEG decoding. DMSACNN incorporates a deep multiscale temporal feature extraction module to capture temporal features at various levels. These features are then processed by a spatial convolutional module to extract spatial features. Finally, a local and global feature fusion attention module is utilized to combine local and global information and extract the most discriminative spatiotemporal features. Main results: DMSACNN achieves impressive accuracies of 78.20%, 96.34% and 70.90% for hold-out analysis on the BCI-IV-2a, High Gamma and OpenBMI datasets, respectively, outperforming most of the state-of-the-art methods. Conclusion and significance: These results highlight the potential of DMSACNN in robust BCI applications. Our proposed method provides a valuable solution to improve the accuracy of the MI/ME-EEG decoding, which can pave the way for more efficient and reliable BCI systems.

Short text classification has gained significant attention in the information age due to its prevalence and real-world applications. Recent advancements in graph learning combined with contrastive learning have shown promising results in addressing the challenges of semantic sparsity and limited labeled data in short text classification. However, existing models have certain limitations. They rely on explicit data augmentation techniques to generate contrastive views, resulting in semantic corruption and noise. Additionally, these models only focus on learning the intrinsic consistency between the generated views, neglecting valuable discriminative information from other potential views. To address these issues, we propose a Simple graph contrastive learning framework for Short Text Classification (SimSTC). Our approach involves performing graph learning on multiple text-related component graphs to obtain multi-view text embeddings. Subsequently, we directly apply contrastive learning on these embeddings. Notably, our method eliminates the need for data augmentation operations to generate contrastive views while still leveraging the benefits of multi-view contrastive learning. Despite its simplicity, our model achieves outstanding performance, surpassing large language models on various datasets. Copyright © 2025, The Authors. All rights reserved.

Cotton growth monitoring is a crucial method for achieving precise management of cotton. Currently, deeplearning-based object detection models have been widely applied in cotton detection. However, existingmodels often struggle to achieve good detection results when facing challenges such as complex environments,occlusion and low contrast. To address these issues, this paper proposes a precise MSHF-YOLO based on theYOLOv8 algorithm. In this network, we introduce Multi-Semantic Spatial and Channel Attention (MSCA)into the backbone, and the upsampling and downsampling modules in the network’s neck are replacedwith the DySample and Adaptive Wavelet Down (AWD) modules to reduce the loss of high-frequencyfeatures. Finally, to further emphasize high-frequency features, we add a high-frequency boost module tothe detection head. The test results show that the algorithm achieves mAP@0.5 and mAP@0.75 of 86.0% and68.2%, respectively, which represents an improvement of 5.5% and 3.5% compared to the original ***, the model size is reduced by 12.5%. Therefore, this algorithm shows great potential for cottongrowth monitoring applications. © 2025, The Authors. All rights reserved.

With the rapid growth of network scale, more network attacks have emerged, the types of network attacks have become more diverse, and the harm they cause to users has become increasingly serious, which has challenged network intrusion detection and protection methods. In order to further improve the quality of network intrusion detection, the study proposes the Multi-Transformer method, which is based on the switchable attention mechanism. It is a detection model with higher security and greater applicability and is applied to the field of network intrusion detection. The study improves the traditional Transformer model and uses self-attention(single head), multi-head attention, and convolution attention in the attention module. At the same time, in order to improve the interpretability of the model, LIME (Local interpretable Model-Agnostic Explanations) was introduced, using Multiple public datasets for testing. The results show that the detection effect of the Multi-Transformer model is better than other machine learning methods. The proposed method is more secure and applicable, and has better anti-noise ability, which has more practical significance in complex and changeable network environments. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

Mamba Adapter: Efficient Multi-Modal Fusion for Vision-Language Tracking

Utilizing the high-level semantic information of language to compensate for the limitations of vision information is a highly regarded approach in single-object tracking. However, most existing vision-language (VL) trackers employ full-parameter fine-tuning, which can easily lead to catastrophic forgetting. Therefore, they fail to fully exploit the prior knowledge of pre-trained models from upstream tasks, resulting in unsatisfactory tracking performance. To alleviate the above problem, we propose a simple yet effective Vision-Language Tracking pipeline based on Mamba Adapter, named MAVLT, which adopts the idea of parameter-efficient fine-tuning (PEFT) to realize the interaction between vision-language modalities. This novel approach offers the following advantages: (1)The knowledge of the upstream pre-trained model is efficiently inherited by freezing its parameters. This ensures that the VL tracking framework only learns the modules for vision and language interaction, with a focus on the fusion between modalities. (2)The modal interaction between language and vision encoders is flexibly bridged in each encoder layer via proposed mamba adapter, enabling efficient interaction of visual and language information at multiple levels. Extensive experiments on five popular vision-language tracking benchmarks validate the effectiveness of the proposed MAVLT. Particularly, the MAVLT achieves 73.4% AUC score on the LaSOT benchmarks with only 0.18%(0.32M) of the total parameters updates.

Enhancing Fish Counting in Sonar Images With Multi-Task Learning and Local-Global Feature Interaction

引用

IEEE Sensors Journal 2025年

作者： Wang, Yuhang Wu, Qunyong Yang, Shiyu Li, Mengmeng Wang, keyue Chen, Xuanyu Fuzhou350128 China Fuzhou University Key Laboratory of Spatial Data Mining and Information Sharing Ministry of Education Fuzhou350128 China

Accurate fish counting is crucial for environmental monitoring and management, with sonar imaging providing a non-intrusive way to gather data in previously inaccessible underwater environments. However, the strong visual similarity between fish and noise in sonar images presents significant challenges in achieving high counting accuracy. Existing methods rely on attention maps to emphasize fish regions but do not fully capture the discriminative features between fish and noise, limiting counting accuracy. To address this, we propose the local-global multi-task transformer (LGMFormer) to enhance fish counting in sonar images. The model employs an encoder-decoder architecture, with density map regression as the primary task and multi-class semantic segmentation as an auxiliary task. By predicting multi-class segmentation maps, the shared network layers fully learn discriminative features between fish and noise. We also develop a segmentation-enhanced density head to further strengthen the connection between tasks. Within LGMFormer, the local-global feature interaction module is designed to fuse local spatial detail features with global correlation features for more precise fish counting. Additionally, a high-level feature guidance module is developed to retain more detail during the feature fusion process between the encoder and decoder. We also develop an automatic image segmentation method based on Otsu's thresholding to create multi-class segmentation labels for sonar images. Extensive experiments on a public sonar fish counting dataset demonstrate that LGMFormer outperforms state-of-the-art methods in counting accuracy, reducing the mean absolute error of count prediction by 17.6% and the false recognition rate by 42.9%.

Sample efficiency has been a challenging problem in visual reinforcement learning, where agents not only learn polices but also extract meaningful state representations for decision making from images. Reinforcement Learning methods that adopt data augmentation have significantly improved sample efficiency. However, prior studies have primarily focused on spatial augmentation, which enhances data diversity but insufficiently exploits temporal information, such as historical states which is critical for time-series-dependent reinforcement learning tasks. To address this gap, we introduce a Spatial-Temporal data Augmentation (STDA) framework designed to enhance the agent's ability to learn task-relevant state representations by effectively leveraging historical state information. We evaluate our approach using the DeepMind Control Suite, and empirical results demonstrate that STDA significantly improves performance, surpassing state-of-the-art methods across a range of tasks.

In accelerated MRI reconstruction problem, directly recovering all the missing k-space data from undersampled measurements is highly ill-posed and often leads to suboptimal performance. To address the problem, we propose a novel deep unfolding network (DUN) with subsampling decomposition (SD) based k-space refinement to mitigate the ill-posedness. Our method employs a parallel network architecture with a primary branch unfolded by gradient descent-inspired optimization process (GD-PB) for reconstruction. Additionally, we introduce an SD-based auxiliary branch (SD-AB) that decompose the inverse problem into moderately corrupted subproblems. We design a novel subsampling mask predictor that captures both global and local spatial correlations in k-space, ensuring the SD-AB effectively preserves the most well-reconstructed subsets as reliable region (RR). The RR in SD-AB is used to periodically refine the intermediate outputs of the GD-PB, achieving improved accuracy. Experimental results reveal that our method significantly outperforms conventional and SD-based DUN techniques, achieving superior PSNR and SSIM results compared with cutting-edge methods.

Classic4Children: Adapting Chinese Literary Classics for Children with Large Language Model

Chinese literary classics hold significant cultural and educational value, offering deep insights into morality, history, and human nature. These works often include classical Chinese and complex narratives, making them difficult for children to read. To bridge this gap, we introduce a child-friendly literary adaptation (CLA) task to adapt the Chinese literary classic into engaging and accessible text for children. However, recent large language models (LLMs) overlook children’s reading preferences (i.e., vivid character portrayals, concise narrative structures, and appropriate readability), which poses challenges in CLA. In this paper, we propose a method called InstructChild, which augments the LLM with these preferences for adaptation. Specifically, we first obtain the characters’ personalities and narrative structure as additional information for fine-grained instruction tuning. Then, we devise a readability metric as the reward to align the LLM with the children’s reading level. Finally, a lookahead decoding strategy is applied to improve the readability of the generated text during inference. To support the evaluation of CLA task, we construct the Classic4Children dataset, which comprises both the original and child-friendly versions of the Four Great Classical Novels of Chinese literature. Experimental results show that our InstructChild significantly improves automatic and human evaluation performance. Copyright © 2025, The Authors. All rights reserved.
