The experimental study on the concrete intensity with different regenerated coarse aggregate substitutive ratio
The different regenerated coarse aggregate substitutive ratio influences on concrete cubic compressive strength,the cubic stress-strain curve was analyzed.The experimental result indicated that different coarse substitutive ratio had certain influences on regenerated concrete intensity.
Short text classification problem need to face some special problems to be solved different from traditional text classification,such as short text length,features sparse.This paper uses the feature extended method based on theme Ontology.It can get better classification performance by considering the semantic relations.Meanwhile,using case-base maintenance learning via the GC(generalization capability)algorithm,which can reduce the case number into K-NN algorithm,can improve efficiency when indexing near neighbor in K-Nearest Neighbor algorithm.The numerical experiments prove the validity of this learning algorithm.
