Parameter Setting and Input Reduction 1
نویسندگان
چکیده
The language acquisition procedure identifies certain properties of the target grammar before others. The evidence from the input is processed in a stepwise order. Section 1 equates that order and its typical effects with an order of parameter setting. The question is how the acquisition procedure derives the order from input evidence. Section 2 proposes a systematic input reduction for functional categories as the key; the reduction residue contains no more than a single nonacquired functional category that is first seen as an optional element only. If that functional category has turned into the most preferred option, the input reduction shifts its acquisition focus to the next functional category. Section 3 and 4 demonstrate how quantitative proportions within the child’s input reduction determine the underlying order as SOV in Dutch before the V-second shift for root sentences is derived. The child’s input reductions are claimed to follow from ignorance rather than from any a priori information. It is argued that parameters are formal properties of the grammatical system that originate as cultural discoveries made by a reflexive mind rather than being task-specific neural a prioris. Section 5 suggests that this view can be extended to syntactic islands.

متن کاملThe Application of Multi-Layer Artificial Neural Networks in Speckle Reduction (Methodology)
Optical Coherence Tomography (OCT) uses the spatial and temporal coherence properties of optical waves backscattered from a tissue sample to form an image. An inherent characteristic of coherent imaging is the presence of speckle noise. In this study we use a new ensemble framework which is a combination of several Multi-Layer Perceptron (MLP) neural networks to denoise OCT images. The noise is...

متن کاملPolynomially Bounded Minimization Problems which are Hard to Approximate
Min PB is the class of minimization problems whose objective functions are bounded by a polynomial in the size of the input. We show that there exist several problems that are Min PB-complete with respect to an approximation preserving reduction. These problems are very hard to approximate; in polynomial time they cannot be approximated within nε for some ε > 0, where n is the size of the input...
