Infrared and visible image fusion (IVIF) aims to integrate complementary information between sensors and generate information-rich high-quality images. However, current methods mainly concentrate on the fusion of the source features from the sensors, ignoring the feature information mismatch caused by the property of the sensors, which results in redundant or even invalid information. To tackle th...Show More
Infrared and visible image fusion (IVIF) aims to obtain an image that contains complementary information about the source images. However, it is challenging to define complementary information between source images in the lack of ground truth and without borrowing prior knowledge. Therefore, we propose a semisupervised transfer learning-based method for IVIF, termed STFuse, which aims to transfer ...Show More
E-learning systems, with their flexibility across time and location, further highlight the importance of consumer electronics in education. Knowledge tracing (KT) is a key part, which depicts the state of students’ knowledge state and predicts students’ future performance. However, due to the sparsity of data in real scenarios, the adequacy of state modeling and the accuracy of prediction are affe...Show More
Knowledge tracing (KT) plays a crucial role in personalized e-learning systems, aiming to model the current knowledge state by tracing the learner’s historical learning records to predict the learner’s future performance. However, most existing deep KT models do not take into account the correlation of questions and knowledge concepts, leading to inaccurate representations of students’ knowledge s...Show More
Semantic information is essential in RGB-T salient object detection (SOD). Most existing methods directly input the extracted low-level features into the interaction module and utilize a simple recursive structure for prediction. Despite their excellent performance in several scenarios, they suffer from capturing and exploiting the attributes and complementary potential between different feature l...Show More
Knowledge tracing models capture student knowledge status through student learning records and predict student performance in the future. Currently popular deep knowledge tracing models are labeled by the rightness or wrongness of a student's answer, ignoring the impact of information such as scores, question difficulty, and individual ability, and using 0 and 1 as labels is too absolute. To this ...Show More
This study proposes an infrared and visible image fusion method based on contrast saliency information guided, termed CSFusion. On the one hand, the gradual recovery network is devised to achieve self-refining processing and cross-stage integration of encoded features. Specifically, the network establishes one-to-one feature reuse between the encoder and the decoder, which can effectively facilita...Show More
In general, the goal of the existing infrared and visible image fusion (IVIF) methods is to make the fused image contain both the high-contrast regions of the infrared image and the texture details of the visible image. However, this definition would lead the fusion image losing information from the visible image in high-contrast areas. For this problem, this article proposed a decoupling network-...Show More
A reinforcement learning based full-duplex multi- user multi-input multi-output (RL-MUFD) Multiple Access Control protocol is proposed. RL-MUFD is a centralized-control MAC protocol where an FD access point (AP) selects multiple simultaneous uplink and downlink streams from half-duplex users and bypasses channel estimation solely based on the geographic locations and the payloads of users. The obj...Show More
The distribution of traffic flow at intersection is an important basis for traffic signal control, based on the characteristics of time and the characteristics of road segments that affect the dynamic changes of traffic flow, this paper proposes an adaptive control strategy for road traffic lights. Firstly, neural network technology is applied to traffic flow state analysis, scientifically define ...Show More
Quality of service (QoS) support is a key attribute for wireless local area networks (WLAN) but is limited in 802.11-based wireless LANs. Based on the IEEE802.11 standard, we present an efficient priority-based polling scheme for WLAN. It becomes increasingly important to support delay-based quality of service in such WLANs. The new scheme differentiates priorities by various access policies which...Show More
HINOC1.0 (High performance Network over Coax) standard has matured and HINOC2.0 standard is being researched about access networks HiNOC MAC protocol in Triple play. Polling control mechanism has been abroadly implicated in the field of access network. This paper uses Markov Chain and probability generating function as analytical method and proposes a new HM_QoS model based on parallel scheduling ...Show More
IEEE 802.11 PCF provides the fairly service without competition, but it is not energy efficiency, so the unnecessary energy consumption caused by empty polling of AP and idle listening of the active nodes will shorten the lifetime when the load is not heavy. A polling control protocol for wireless sensor network, namely Limited-K service Polling Schedule with Sleeping (K-PSSS) was proposed for the...Show More
Polling as one kind of the TDMA medium access control protocols has the advantage of energy conservation, however, its extensibility is not as good as that of contention-based protocol. The controllable threshold polling medium access protocol (CTP-MAC) in this paper is designed to realize the self-organizing in slot assignment and synchronization. Methods of the imbedded Markov-chain theory and t...Show More
