Efficient radio resource management in integrated terrestrial and non-terrestrial networks by Birabwa, Denise Joanitah

“…Simulation results reveal that as the number of users in the network increases, the acquired data rate of the MA3DQN is within 0.48% and 0.42% of that achieved by the GA and ILP, respectively, and outperforms all other algorithms. Notably, the proposed MA3DQN algorithm presents the best running time, attaining a gain of 99.9% over the GA algorithm, which performs the poorest among the algorithms characterised by polynomial worst-case time complexity. …”

ISO-maps for Non-linear Dimension Reduction - Addressing Geometric and Numerical Issues Observed in Practice by Evert, Francois

“…We test and demonstrate an alternative strategy for approximating distances by relaxing the constraint that the shortest path needs to be found, substituting the condition that any (reasonable) path between points on the graph suffices for purposes of this algorithm. Lastly we demonstrate how the proposed remediations/variations on the algorithm can be used to conduct dimensionality reduction on real-world data sets, and provide some conclusions and possible future reseach topics.…”
