Improving Investment Suggestions for Peer-to-Peer (P2P) Lending via Integrating Credit Scoring into Profit Scoring

Yan Wang, Xuelei Sherry Ni

In the peer-to-peer (P2P) lending market, lenders lend the money to the borrowers through a virtual platform and earn the possible profit generated by the interest rate. From the p…

A two-stage hybrid model by using artificial neural networks as feature construction algorithms

Yan Wang, Xuelei Sherry Ni, Brian Stone

We propose a two-stage hybrid approach with neural networks as the new feature construction algorithms for bankcard response classifications. The hybrid model uses a very simple ne…
