Summary: Similarity caching systems are gaining attention for their various applications, but balancing efficiency and accuracy is a challenge. The offline content placement problem is proven to be NP-hard, but polynomial algorithms can be used to approach optimal solutions in discrete cases. Continuous problem formulation in tree topologies offers simple structure solutions as the content space grows.

Summary: Due to limited monitoring and measurement devices, timely identification of distribution grid topology has been a challenge. Therefore, this article proposes a power grid topological generative adversarial network (Gridtopo-GAN) model to identify the distribution grid topology with limited measurements. The model efficiently handles large-scale systems with different topological configurations by leveraging the topology preserved node embedding architecture and the generative capability of GAN. Numerical simulations on various distribution systems demonstrate the effectiveness and efficiency of the proposed topology identification model.

Summary: This paper presents a method for estimating the admittance matrix of open-loop distribution networks based on active/reactive power injection and voltage magnitude data, improving the operation and control capabilities of the distribution network. By deriving the linear relationship between the admittance matrix and the measurements using decoupled linear power flow equations, and proposing a total least squares regression method, accurate estimation of the admittance matrix is achieved. Case studies on the IEEE 33-bus system demonstrate the effectiveness, accuracy, and efficiency of the proposed method.

Summary: In this letter, a mathematical model is proposed to preserve privacy in a network caching system involving a server and a cache-aided end user. An efficient content caching method is presented to maximize privacy preservation while maintaining the average delivery load at a given level. The Pareto optimal nature of the proposed epsilon-constraint optimization approach allows for achieving the maximum privacy degree possible under any given average delivery load.

Summary: In this paper, we consider the index coding problem of delivering distinct files to multiple users with minimum delay. Each user has access to a subset of other files as side information. We generalize the concept of MinRank characterization and the clique cover algorithm by incorporating the idea of Zero-Forcing in MIMO systems. Our findings suggest that increasing the number of transmitters can significantly reduce the delivery delay.
