Randomized Average Kaczmarz Algorithm for Tensor Linear Systems

Mathematics, 2022
For solving tensor linear systems under the tensor–tensor t-product, we propose the randomized average Kaczmarz (TRAK) algorithm, the randomized average Kaczmarz algorithm with random sampling (TRAKS), and their Fourier version, which can be effectively ...

Probabilistic Algorithmic Knowledge [PDF]

Logical Methods in Computer Science, 2005
The framework of algorithmic knowledge assumes that agents use deterministic knowledge algorithms to compute the facts they explicitly know. We extend the framework to allow for randomized knowledge algorithms.

Massive Fishing Website URL Parallel Filtering Method

IEEE Access, 2018
A randomized fingerprint model is proposed, which can effectively reduce the false positive rate by generating a unique fingerprint for each URL. The model is also used to improve the Wu and Manber (WM) algorithm, which is a multi-string matching ...

Reduction of Phase Shifters in Planar Phased Arrays Using Novel Random Subarray Techniques

Applied Sciences
Reducing the number of phase shifters by grouping antenna elements into subarrays has been extensively studied for decades. The number of phase shifters directly affects the cost, complexity, and power consumption of the system.
