Entropy and Autoencoder-Based Outlier Detection in Mixed-Type Network Traffic Data

2021

Mixed-type data containing categorical and numerical features are pervasive in real life, but very limited outlier detection methods are available for these data. Some existing methods handle mixed-type data by feature converting, whereas their performance …

Quantum Algorithms for the Multiplication of Circulant Matrices and Vectors

2024 · Information

This article presents two quantum algorithms for computing the product of a circulant matrix and a vector. The arithmetic complexity of the first algorithm is O(Nlog2N) in most cases. For the second algorithm, when the …
