Digital Twin Empowered Content Caching in Social-Aware Vehicular Edge Networks
IEEE Transactions on Computational Social Systems, 2022The rapid proliferation of smart vehicles along with the advent of powerful applications bring stringent requirements on massive content delivery. Although vehicular edge caching can facilitate delay-bounded content transmission, constrained storage ...

Cooperative Multilayer Edge Caching in Integrated Satellite-Terrestrial Networks
IEEE Transactions on Wireless Communications, 2022The integrated satellite-terrestrial network is promising to provide global broadband communication service. However, the long propagation delay of satellite-terrestrial links will lead to high communication delay when users access the Internet via ...

Deep Reinforcement Learning for Cooperative Content Caching in Vehicular Edge Computing and Networks
IEEE Internet of Things Journal, 2020In this article, we propose a cooperative edge caching scheme, a new paradigm to jointly optimize the content placement and content delivery in the vehicular edge computing and networks, with the aid of the flexible trilateral cooperations among a macro ...

Proceedings of the twenty-eighth ACM SIGMOD-SIGACT-SIGART symposium on Principles of database systems, 2009
We introduce the similarity caching problem, a variant of classical caching in which an algorithm can return an element from the cache that is similar, but not necessarily identical, to the query element. We are motivated by buffer management questions in approximate nearest-neighbor applications, especially in the context of caching targeted ...

Annex cache: a cache assist to implement selective caching
Microprocessors and Microsystems, 1999Efficient instruction and data caches are extremely important for achieving good performance from modern high performance processors. Conventional cache architectures exploit locality, but do so rather blindly. By forcing all references through a single structure, the cache’s effectiveness on many references is reduced.

Accelerating Diffusion Transformers with Token-wise Feature Caching
International Conference on Learning RepresentationsDiffusion transformers have shown significant effectiveness in both image and video synthesis at the expense of huge computation costs. To address this problem, feature caching methods have been introduced to accelerate diffusion transformers by caching ...

Advising cache for lower cache
Proceedings of the 11th International Conference on Ubiquitous Information Management and Communication, 2017In a virtualized environment, such as a cloud computing environment, guest and host operating systems run simultaneously. Both of the operating systems have page caches for disk accesses. In such an environment, the host operating system cache does not work effectively because of negative temporal locality of access and duplicated storing in both the ...

Fundamental Limits of Coded Caching With Multiple Antennas, Shared Caches and Uncoded Prefetching
IEEE Transactions on Information Theory, 2020The work explores the fundamental limits of coded caching in the setting where a transmitter with potentially multiple ( $N_{0}$ ) antennas serves different users that are assisted by a smaller number of caches.
