Context-aware emotion recognition (CAER) is a complex and significant task that requires perceiving emotions from various contextual cues. Previous approaches primarily focus on designing sophisticated architectures to extract emotional cues images. However, their knowledge confined specific training datasets may reflect the subjective biases of annotators. Furthermore, acquiring large amounts labeled data often challenging in real-world applications. In this paper, we systematically explore...

Zero-shot coordination problem in multi-agent reinforcement learning (MARL), which requires agents to adapt unseen agents, has attracted increasing attention. Traditional approaches often rely on the Self-Play (SP) framework generate a diverse set of policies policy pool, serves improve generalization capability final agent. However, these frameworks may struggle capture full spectrum potential strategies, especially real-world scenarios that demand balance cooperation with competition. In...

Wireless sensor networks are a significant subfield of distributed systems, and large number their applications require time synchronization. Sensor nodes powered by batteries. In order to reduce the interference peripheral environment on node as much possible, size is relatively small circuit design, storage, calculation simple. Therefore, wireless network have limited energy, low computing power, communication capacity. addition, clock usually realized through local crystal oscillator CPU...

Training time is an important consideration in classification practices. Various algorithms like SVM usually suffer from high computational cost during the training process.
