With Spark streaming the algorithms were executed both in local mode, and cluster mode (Fig. 2).
One simple way to achieve this is to identify cell subsets with modes (peaks), and cluster all components that share the same mode as a single cell subset.
In this paper, we are making use of both K modes clustering and cluster selection criteria of LCC cluster analysis with the following reasons: a) K modes are a better option for data with large number of categorical attributes.
Two modes of metallic glass sputtering were distinguished: smooth film mode and clustered film mode.
Subsequently, the software package USEARCH version 6.0 was applied for denoising, chimera detection (de novo mode) and clustering into OTUs based on a 97% sequence identity [ 83, 84].
Firstly, the uniqueness of TRAM general basic architecture, which dynamically integrates an advanced and flexible relational database with parsing and meta-analysis capability, a map graphic displayer and a two-modes ('Map' and 'Cluster') analyzer searching for significantly over/under-expressed genomic regions, starting from any source of global gene expression profiles data.
For further analysis, we used the following features that produced four clusters of CpGo/e: (cluster 1) species with one mode Mo ≥ 0.69 and SD an0.12, (cluster 2) species with one mode Mo ≥ 0.69 and SD ≥ 0.12, (cluster 3) species with one mode Mo s0.69, and (cluster 4) species with (a) two modes or (b) one mode and a skewness smaller than −0.04.
N j is the number of modes in the jth cluster, and W ij is the correlation weight of mode X i and cluster j.
In the formula above, W ij is the correlation weight of mode X i and cluster j, X i (i = 1, ⋯, N) is the position of the ith mode, and Z j (j = 1, ⋯, K) is the center of the jth cluster, which can be found in Eq. (2): {Z}_j=frac{1}{N_j}{displaystyle sum_{i=1}^N{w}_{ij}{x}_i} (2).
Spark experiments were executed in local and cluster modes.
