Tu, J; Liu, Y; Zhou, M and Li, R (2021) Prediction and analysis of compressive strength of recycled aggregate thermal insulation concrete based on GA-bp optimization network. Journal of Engineering, Design and Technology, 19(2), pp. 412-422. ISSN 1726-0531
Abstract
This paper aims to predict the 28-day compressive strength of recycled thermal insulation concrete more accurately. The initial weights and thresholds of BP neural network are improved by genetic algorithm on MATLAB 2014 a platform. Genetic algorithm–back propagation (GA-BP) neural network is more stable. The generalization performance of the complex is better. The GA-BP neural network based on the training sample data can better realize the strength prediction of recycled aggregate thermal insulation concrete and reduce the complex orthogonal experimental process. GA-BP neural network is more stable. The generalization performance of the complex is better.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
