These evaluation criteria compute some statistics for each region or class in a segmentation result.
No clinical symptom is pathognomonic, and consensus documents suggest nasal fibroendoscopy (NF) or imaging criteria (computed tomography, magnetic resonance imaging) as the gold standards for diagnosis of CRS.
The optimal number of clusters supported by the data was identified based on consensus on three criteria computed, the R2 (proportion of the total variance accounted by the clusters), R2 ratio [R/ 1-R ], and the pseudo-F statistic: Pseudo F = ⌊ R/ 1-R ]1)⌋/⌊(1 - R )/(N - G )⌋ where G = number of clusters and, N = number of cDNAs.
Indeed, no threshold expression was given and the decision was taken using the values minimizing the AIC and/or MDL criterion computed by simulation.
Our controller validation criterion computes an upper bound for the worst case performance, measured in terms of the H∞-norm of a weighted closed loop transfer matrix, achieved by a given controller over all plants in such uncertainty sets.
We note that since new distances d zk are always linear combinations of the previous distances, all Q-criteria computed throughout the NJ algorithm are linear combinations of the original pairwise distances.
Our new proposed criterion has been shown to be more accurate than other criteria in computing the effective properties of composites for aspect ratios up to 60.
Two important parameters in hierarchical clustering are the similarity measure between two data points and the criteria for computing the inter-cluster similarity.
Afterwards, we draw the directed network according to the collective IFPR, and then design an algorithm to identify the best and worst criteria through computing the out-degrees and in-degrees of the directed network.
Accordingly, this paper presents a parametric study confirming the importance of conventional design criteria and computing the differences in the seismic permanent displacement of pier-shallow foundation systems by differentiating the values of safety factors incorporated in the conventional design criteria.
