Support Vector Machines in Ordinal Classification: An Application to Corporate Credit Scoring

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 the 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 credit rating system takes several characteristics of a counterparty as inputs and assigns this co...

Constructive Gradient Neural Network

The paper deals with a description of a constructive neural network based on gradient initial setting of its weights. The network has been used as a pattern classifier of two dimensional patterns but it can be generally used to n × m associative problems. A network topology, processes of learning and retrieving, experiments and comparison to other neural networks are described.
