The first phase of the algorithm guarantees that a single camera becomes a cluster head within its communication range. However, cameras that can communicate with the cluster head in multiple hops may be left without a leader.Figure 23.3(b)shows an example of this situation. Cameras 1 and 2 ...
The nodes are then transferred to neighboring modules in a random sequential manner, resulting in the greatest reduction of the map equation. If no move leads to a further reduction of the map equation, the node remains in its original place. The method is done until the map equation can ...
In such cases, it may be advisable to draw a simple random sample of houses and survey all the households belonging to sample households. This procedure is known as cluster sampling. It is also a common experience in sample surveys on sensitive data that someone is agreed to response but ...
What problems/limitations could prevent a truly random sampling and how can they be prevented? In a paired difference experiment, when should the observations be paired, before or after the data are collected? explain. Explain a one-tailed and two-tailed test. Use an example. D...
7, in green) were aligned with subgroup centroids before dimensionality reduction was applied, with minor random sampling error. Dimensionality reduction did impact cluster separation. MDS subtly exaggerated centroid distances across all centroid separations in original space (Fig. 7, in blue). UMAP ...

A cluster randomized trial involves randomizing social units or clusters of individuals, rather than the individuals themselves. This design, which is increasingly used for evaluating health-care, screening and educational interventions [1–3], presents specific constraints that must be considered during...
These “random” structures are of great importance for the parametrization of the present ACE potential since they inform the model about out-of-equilibrium and highly distorted configurations that are relevant for the dynamics of complex defects, phase transformations, and liquid phases. It has ...
a non-random initialization should be used (Kobak and Linderman2021; Wang et al.2021; McInnes et al.2018, e.g.). UMAP uses a spectral embedding initialization by default. Other methods, for example, TriMAP and PaCMAP, use PCA for initialization (Wang et al.2021). t-SNE, in contrast,...
4c) were reported, where A block consisted of random copolymers of LiM and PEGM, while B block represented poly(PhEtM) [107]. Wherein, the morphology and ionic conductivity of the A-B block copolymers were well conveniently regulated by altering the ratio of LiM/PEGM and ionic/nonionic ...
