Inadequate feeding and care may contribute to high rates of stunting and underweight among children in rural families in India. This cluster-randomized trial tested the hypothesis that teaching caregivers appropriate complementary feeding and strategies for how to feed and play responsively through home-visits would increase children's dietary intake, growth and development compared with home-v...

Abstract Vector symbolic architectures (VSA) are a viable approach for the hyperdimensional representation of data, such as documents, syntactic structures, or semantic frames. We present rigorous mathematical framework phrase structure trees and parse context-free grammars (CFG) in Fock space, i.e. infinite-dimensional Hilbert space being used quantum field theory. define novel normal form CFG...

Constructive methods for obtaining the regular grammar counterparts for some sub-classes of the context free grammars (cfg) have been investigated by many researchers. An important class of grammars for which this is always possible is the one-letter cfg. We show in this paper a new constructive method for transforming arbitrary one-letter cfg to an equivalent regular expression of star-height ...

Sadly, I am writing this Editorial to let you know of our decision to close Comparative and Functional Genomics as of this issue. Unfortunately, despite much hard work by the entire Editorial Board and the team at Wiley, CFG has not achieved what we had hoped and we feel that no amount of effort will be enough to rectify this. This will be the final issue of the journal. However, its archive wi...

Much attention has been paid to RNA secondary structure predicition based on context-free grammar (cfg) since cfg can represent stem-loop structure by its derivation tree. Especially, techniques based on CKY (Cocke-Kasami-Younger) algorithm have been widely investigated [1]. Pseudoknots play an important role in RNA functions such as ribosomal frameshifting and splicing. A database (PseudoBase)...

Valiant showed that Boolean matrix multiplication (BMM) can be used for CFG parsing. We prove a dual result: CFG parsers running in time O([Gl[w[ 3-e) on a grammar G and a string w can be used to multiply m x m Boolean matrices in time O(m3-e/3). In the process we also provide a formal definition of parsing motivated by an informal notion due to Lang. Our result establishes one of the first lim...

SGStudio is a grammar authoring tool that eases semantic grammar development. It is capable of integrating different information sources and learning from annotated examples to induct CFG rules. In this paper, we investigate a modification to its underlying model by replacing CFG rules with n-gram statistical models. The new model is a composite of HMM and CFG. The advantages of the new model i...
