Application of Machine Learning Algorithms for Traffic Forecasting in Dynamic Optical Networks with Service Function Chains

Autor: Szostak Daniel, Walkowiak Krzysztof

Publikováno v: Foundations of Computing and Decision Sciences, Vol 45, Iss 3, Pp 217-232 (2020)

Knowledge about future optical network traffic can be beneficial for network operators in terms of decreasing an operational cost due to efficient resource management. Machine Learning (ML) algorithms can be employed for forecasting traffic with high

Liquid Neural Network-based Adaptive Learning vs. Incremental Learning for Link Load Prediction amid Concept Drift due to Network Failures

Autor: Ayoub, Omran, Andreoletti, Davide, Knapińska, Aleksandra, Goścień, Róża, Lechowicz, Piotr, Leidi, Tiziano, Giordano, Silvia, Rottondi, Cristina, Walkowiak, Krzysztof

Adapting to concept drift is a challenging task in machine learning, which is usually tackled using incremental learning techniques that periodically re-fit a learning model leveraging newly available data. A primary limitation of these techniques is

Traffic Weaver: semi-synthetic time-varying traffic generator based on averaged time series

Autor: Lechowicz, Piotr, Knapińska, Aleksandra, Włodarczyk, Adam, Walkowiak, Krzysztof

Traffic Weaver is a Python package developed to generate a semi-synthetic signal (time series) with finer granularity, based on averaged time series, in a manner that, upon averaging, closely matches the original signal provided. The key components u

A column generation technique for routing and spectrum allocation in cloud–ready survivable elastic optical networks

Autor: Goścień Róża, Walkowiak Krzysztof

Publikováno v: International Journal of Applied Mathematics and Computer Science, Vol 27, Iss 3, Pp 591-603 (2017)

Driven by increasing user requirements and expectations, the fast development of telecommunications networks brings new challenging optimization problems. One of them is routing and spectrum allocation (RSA) of three types of network flows (unicast,

Incremental Recursive Ranking Grouping for Large Scale Global Optimization

Autor: Komarnicki, Marcin Michal, Przewozniczek, Michal Witold, Kwasnicka, Halina, Walkowiak, Krzysztof

Real-world optimization problems may have a different underlying structure. In black-box optimization, the dependencies between decision variables remain unknown. However, some techniques can discover such interactions accurately. In Large Scale Glob
