Supply chain finance credit risk assessment using support vector machine–based ensemble improved with noise elimination

Abstract

Recently, support vector machines, a supervised learning algorithm, have been widely used in the scope of credit risk management. However, noise may increase the complexity of the algorithm building and destroy the performance of classifier. In our work, we propose an ensemble support vector machine model to solve the risk assessment of supply chain finance, combined with reducing noises method. The main characteristics of this approach include that (1) a novel noise filtering scheme that avoids the noisy examples based on fuzzy clustering and principal component analysis algorithm is proposed to remove both attribute noise and class noise to achieve an optimal clean set, and (2) support vector machine classifiers, based on the improved particle swarm optimization algorithm, are seen as component classifiers. Then, we obtained the final classification results by combining finally individual prediction through AdaBoosting algorithm on the new sample set. Some experiments are applied on supply chain financial analysis of China’s listed companies. Results indicate that the credit assessment accuracy can be increased by applying this approach.

An ensemble machine learning approach for forecasting credit risk of agricultural SMEs’ investments in agriculture 4.0 through supply chain finance

“…Additionally, higher classification precision implies that FSPs can correctly identify non-credit risky agriculture 4.0 investments among all the positive samples (Zhu et al, 2019 ). The recall value quantifies the ability to pinpoint non-credit risky agriculture 4.0 investments from all the samples that should have been labeled as non-risky (Ying Liu & Huang, 2020 ). Moreover, the F-measure is the harmonic mean of the precision rate (i.e., positive predictive) and the recall rate (i.e., sensitivity).…”

Improving AdaBoost Classifier to Predict Enterprise Performance after COVID-19

“…test data correct rate = volume of records who is classified correctly by machine learning tool volume of records in test data set (9) The test data correct rate was calculated based on the semiconductor enterprise predictive result and the tourism enterprise predictive result. The AdaBoost was trained by the semiconductor enterprise data and the tourism enterprise data individually.…”

“…The machine learning model can be used to classify and make predictions in each field, such as weather predictions [5], flight predictions [6], water quality predictions [7] etc. In the enterprise field, the machine learning model has been developed to execute corporate bankruptcy predictions [8], credit risk evaluations [9], enterprise performance evaluations [10] etc.…”

“…AdaBoost is also one kind of popular machine learning model. AdaBoost can effectively predict the performance of enterprise in the past literature [8,9]. The goal of this research is to improve the AdaBoost classifier in order to allow this machine learning model to effectively predict enterprise performance after 2020.…”
