Finally, after time-constraint cluster algorithm grouping frames with similar content, the frames with maximum saliency value are selected as key-frames.
The genomic map of a representative phage from each subcluster is given in Figure 6 as an example, however the larger phages are excluded due to space constraints (clusters A through F are shown).
The genomic map of a representative phage from each subcluster is given in Figure 6 as an example, however the larger phages are excluded due to space constraints (clusters A through G are shown).
These group data are reported at a voxel-wise statistical threshold of P<0.001, with an additional constraint of cluster size (>5 contiguous voxels [60].
This observation, in conjunction with the evolutionary conservation (presumably due to functional constraint) of Cluster I, suggests the possible evolutionary acquisition of important functions independent of enzymatic activity.
Constraints on cluster shape are imposed through early stopping, a double connection requirement and a maximum linkage criteria.
And the nonnegative constraints on cluster indicator matrix H may be an insufficient condition for achieving sparseness in some cases [ 20].
Comparative experiments conducted on real datasets and with two distinct representative constraint-based clustering algorithms show that our approach significantly improves clustering quality while minimizing the number of human expert solicitations.
By imposing network topology constraints on clusters of expression data, the biological interpretation of the clusters becomes easier, and, as we shall see, one can detect weaker signals that were indistinguishable by extant methods.
Contrary to these approaches, our method is designed to be beneficial for all constraint-based clustering algorithms.
We could have determined these physical constraints by clustering co-regulated genes and training the rules of binding for their regulators.
