Figure 4 shows individual locations in a reduced factorial space defined by multidimensional scaling applied to individual proximities computed from RF, and projection of factor scores in the first three dimensions of PLS-DA.
The primary measures were cumulative search-error on training trials and a learning index (Gallagher's proximity index) computed from the trials given over the course of training.
This network representation of the face-to-face proximity relations, computed as a function of time for an entire experiment, is the basic piece of information that we use for the analysis.
Given that the geographical distance for other colleagues likely affects the possibility of interaction between them, and thus the position that an individual occupies within the network, a variable named Geographical Proximity was computed as the reciprocal of the average geographical distance (expressed in kilometers) of each sampled physician from their organizational colleagues.
Abouheif proximities were computed from the phylogenetic trees using the function 'proxTips' in the package 'adephylo' in R [ 79].
Computing the proximity factor for nodes in the scenario in Figure 2, we obtain the values shown in Table 1.
Later, in the paper by Koren et al. [ 15], an improved measure called cycle free effective conductance was proposed by using only the cycle free paths in computing the proximity.
The network model is constructed on the basis of proximity of the computed data on its total porosity, pore-size function, and simulated mercury intrusion curve to the respective experimental data.
A simple approach for evaluating proximity is to compute the average of the difference of ratings for each movie returned by Eq. 8, as shown in Eq. 9. frac{sum_{text{textsc{SimilaritySet}}left text{AID}, text{BID}right)} {lverttext{RatingA} - text{RatingB}rvert}}{mathcal{C}left text{textsc{SimilaritySet}}left text{AID}, text{BID}right)right)} (9).
The proximity graph is computed in real-time by the data collection system, and the visualization is updated continuously [32].
The model has been shown to spatially compute proximity graphs, Voronoi diagrams, combinatorial optimization, collective transport, and collective amoeboid movement.
