Processing Redundant Information
نویسنده
چکیده
When stimuli differed on two dimensions (size and brightness), either of which could furnish sufficient information for a correct response, reaction times were faster than when stimuli differed on only one dimension. This result holds true even when individual differences in dimension preferences are taken into account. A model of parallel processing of the different dimensions is proposed and extended to Posner's taxonomy of informationprocessing tasks. The model emphasizes 6"s ability to initiate a successive processing stage as soon as sufficient information for a correct response has been gathered. This ability enables .? to capitalize on the variance of the times of the component processes by which the values of the different dimensions arc determined.

A New Hybrid Framework for Filter based Feature Selection using Information Gain and Symmetric Uncertainty (TECHNICAL NOTE)
Feature selection is a pre-processing technique used for eliminating the irrelevant and redundant features which results in enhancing the performance of the classifiers. When a dataset contains more irrelevant and redundant features, it fails to increase the accuracy and also reduces the performance of the classifiers. To avoid them, this paper presents a new hybrid feature selection method usi...
متن کاملDistributed Rule - Based Inference in the Presence of Redundant Information
The problem of processing redundant information (also known as “double counting”) has been addressed in distributed Level 1 Fusion systems over the past decade. Some approaches for avoiding the ill-effects of processing redundant data include: tagging all data items with a unique identifier, controlling the flow of data throughout the network or tracking pedigree information for each data item....
متن کاملASIC Design of Butterfly Unit Based on Non-Redundant and Redundant Algorithm
Fast Fourier Transform (FFT) processors employed with pipeline architecture consist of series of Processing Elements (PE) or Butterfly Units (BU). BU or PE of FFT performs multiplication and addition on complex numbers. This paper proposes a single BU to compute radix-2, 8 point FFT in the time domain as well as frequency domain by replacing a series of PEs. This BU comprises of fused floating ...
متن کاملDevelopmental Changes in Children’s Processing of Redundant Modifiers in Definite Object Descriptions
This paper investigates developmental changes in children's processing of redundant information in definite object descriptions. In two experiments, children of two age groups (6 or 7, and 9 or 10 years old) were presented with pictures of sweets. In the first experiment (pairwise comparison), two identical sweets were shown, and one of these was described with a redundant modifier. After the d...
متن کاملAn approach to fault detection and correction in design of systems using of Turbo codes
We present an approach to design of fault tolerant computing systems. In this paper, a technique is employed that enable the combination of several codes, in order to obtain flexibility in the design of error correcting codes. Code combining techniques are very effective, which one of these codes are turbo codes. The Algorithm-based fault tolerance techniques that to detect errors rely on the c...
متن کاملA Monte Carlo-Based Search Strategy for Dimensionality Reduction in Performance Tuning Parameters
Redundant and irrelevant features in high dimensional data increase the complexity in underlying mathematical models. It is necessary to conduct pre-processing steps that search for the most relevant features in order to reduce the dimensionality of the data. This study made use of a meta-heuristic search approach which uses lightweight random simulations to balance between the exploitation of ...
