Missing Data Preprocessing in Credit Classification: One-Hot Encoding or Imputation?
TL;DR: For high-missing-rate coupled with data-imbalance issue, the proposed one-hot encoding based imputation method shows not only high accuracy, but also great robustness and needs less of computational time.
Book ChapterDOI
Neural network metalearning for credit scoring
TL;DR: The use of supervised neural networks as a metalearning technique to design a credit scoring system to solve the problem of data shortage problem.
Journal ArticleDOI
A neural network application in personnel scheduling
Gang Hao,Kin Keung Lai,M. Tan +2 more
TL;DR: A neural network model following a relatively new modeling approach to solve a real rostering case is introduced and the experiment results comparing the neural network method with three popular heuristics, i.e. simulated annealing, Tabu search and genetic algorithm are provided.
Journal ArticleDOI
Mutual funds performance evaluation based on endogenous benchmarks
TL;DR: The root reasons of inefficiency and ways for improving performance are identified, and the most important conclusion is that the ranking of mutual funds in China depends mostly on system risk control.
Journal ArticleDOI
Channel competition and coordination of a dual-channel supply chain with demand and cost disruptions
TL;DR: In this paper, the impacts of simultaneous disruption of demand and cost on pricing, production and coordination of a dual-channel supply chain with one manufacturer and one retailer are examined, and the impact of such a model on the performance of a single retailer and a single manufacturer is discussed.
