Research on Multi-Classification of Credit Rating of Small and Medium-Sized Logistics Companies Based on Ordinal Regression Support Vector Machine
نویسنده
چکیده
Small and medium-sized logistics companies are playing an increasingly important part in social life. We selected the data of small and medium-sized logistical companies in Beijing, Shanghai and Guangzhou, reformulated ordinal regression support vector machine method so that different input points could make different contributions to decide hyper plane, to analyze multi-classification of credit rating problem, and divided them into four different categories to demonstrate the good performance. The effectiveness of this improved method is verified in multi-classification of credit rating of small and medium-sized logistical companies and the results show that our method is promising and can be used to other multi-classification problems.

متن کاملSupport vector machines in ordinal classification
Risk assessment of credit portfolios is of pivotal importance in the banking industry. The bank that has the most accurate view of its credit risk will be the most profitable. One of the main pillars in assessing credit risk is the estimated probability of default of each counterparty, i.e., the probability that a counterparty cannot meet its payment obligations in the horizon of one year. A cr...
