Therefore, for this specialized case, it can be verified theoretically that the proposed LTVFF-DRLS and LCTVFF-DRLS algorithms are convergent in terms of the learning curve and the convergence rate is related to the varying forgetting factors.
The term convergent, describes a relationship in which individuals exchange information that confirms their causal understanding of an ambiguous situation (intra-coalition learning (Weible et al., 2010)).
However, Paul et al. (2013) used the term "convergent" to mean that a site has experienced more than one amino acid change (Paul et al. 2013), which we refer to as a multihit site.
Plant heterotrophy is especially interesting in the context of evolutionary biology as it represents an example of convergent evolution, a term that refers to the emergence of the same trait in distant lineages.
Such similarities of form between only distantly related organisms is termed "convergent evolution" and there are numerous examples of this in the fossil record and alive today (think of the hydrodynamic shapes of fish, dolphins and penguins).
Then, based on two basic Zhang functions (ZFs) and the intrinsically nonlinear method of ZNN design, two finite-time convergent ZNN models (termed ZNN-1 model and ZNN-2 model) are first proposed and investigated for time-varying matrix pseudoinversion.
By exploiting the other three simplified ZFs and the extended nonlinearization method, three simplified finite-time convergent ZNN models (termed ZNN-3 model, ZNN-4 model and ZNN-5 model) are sequentially proposed.
The elastic solution in an anisotropic trimaterial is solved as a rapidly convergent series in terms of complex potentials via the successive iterations of the alternating technique in order to satisfy the continuity condition along the interfaces between dissimilar media.
Discriminant correlations that exceed convergent correlations are termed comparison violations.
The discovery of peptides mimicking protein protein interactions by phage display is a well-known phenomenon termed convergent evolution.
