Modularity, noise, and natural selection.
Most biological systems are formed by component parts that are to some degree interrelated. Groups of parts that are more associated among themselves and are relatively autonomous from others are called modules. One of the consequences of modularity is that biological systems usually present an unequal distribution of the genetic variation among traits. Estimating the covariance matrix that des...
متن کاملNatural clustering: the modularity approach
We show that modularity, a quantity introduced in the study of networked systems, can be generalized and used in the clustering problem as an indicator for the quality of the solution. The introduction of this measure arises very naturally in the case of clustering algorithms that are rooted in Statistical Mechanics and use the analogy with a physical system.

متن کاملReversibility And Modularity In Natural Language Generation
A consequent use of reversible grammars within natural language generation systems has strong implications for the separation into strategic and tactical components. A central goal of this paper is to make plausible that a uniform architecture for grammatical Processing will serve as a basis to achieve more flexible and efficient generation systems. 1 Introduction In general, the goal of parsin...
متن کاملModularity: a natural choice for improving generalization
One of the principal motivations for constructing artificia l modular neural networks comes from biological neural systems, where modularity can be observed at different levels of organization. Starting from some theoretical results that roughly state that modular architectures generalize better than their monolithic counterparts, we test through simulations this assertion on three problems: th...
متن کاملNatural Language and Natural Selection
Many people have argued that the evolution of the human language faculty cannot be explained by Darwinian natural selection. Chomsky and Gould have suggested that language may have evolved as the by-product of selection for other abilities or as a consequence of as-yet unknown laws of growth and form. Others have argued that a biological specialization for grammar is incompatible with every ten...
