In this paper, we investigate an optimization scheme for extreme learning machine (ELM) regression, named OELR, to overcome the limitation of ELM that it may lead to overfitting on large training data sets. OELR amounts to minimization of ε-insensitive loss and minimization of the norm of the output weights of single hidden layer feedforward networks(More)
A tumor microenvironment may promote tumor metastasis and progression through the dynamic interplay between neoplastic cells and stromal cells. In this work, the most representative and significant stromal cells, fibroblasts, endothelial cells, and macrophages were used as vital component elements and combined with bladder cancer cells to construct a(More)
The pullulanase encoding gene from Bacillus naganoensis was successfully overexpressed in Escherichia coli both intracellularly and extracellularly using expression vector pET22b (+). The distribution of recombinant protein was significantly affected by temperature and carbon and nitrogen sources. The highest levels of extracellular and intracellular(More)
