Summary

Action Recognition (AR) is a critical area of research that enables machines to understand human activities from multimodal data sources such as video, sensor data, and wearable devices. This special issue for CMC—Computers, Materials & Continua focuses on cutting-edge advancements in AR, with a strong emphasis on privacy, explainability, and optimization for real-world applications. We invite contributions that push the boundaries of AR by addressing the challenges of real-time processing, robustness in noisy environments, and ensuring privacy-preserving techniques.


Submissions are sought on innovative methods for action recognition that involve deep learning architectures, such as convolutional networks, recurrent networks, transformers, and graph-based models. We are particularly interested in methods that enhance the efficiency of AR algorithms, including real-time action recognition, optimization for computational resources (e.g., latency, energy, throughput), and techniques for increasing robustness and generalization across diverse datasets. Additionally, submissions should focus on providing explanations for model decisions through explainable AI approaches, ensuring that AR models are interpretable and trustworthy in practical applications.


Potential Topics (not limited to):
· Deep Learning for Action Recognition (e.g., CNNs, RNNs, Transformers)
· Real-Time Action Recognition and Optimization (Latency, Energy, Throughput)

    Abstract Video representation learning faces very challenging goals, including spurious temporal correlations, confounding visual features, and failure to learn real causal relationships between video events. Current transformer-based approaches learn statistical relationships rather than causal interactions, leading to weak generalization and high sensitivity to distribution changes. The current paper proposes a new Counterfactual Transformer Network, named CauFormer-V, that combines causal inference concepts with temporal representation learning for video. The framework was proposed and includes three main innovations, (1) a Causal Temporal Attention (CTA) mechanism, a mechanism that specifically models causal dependencies among video frames via do-calculus intervention,… More >
