| - | ====== Introduction ====== | ||
| - | |||
| - | Classification is an important problem in machine learning. It can be used | ||
| - | in a variety of applications, such as separating apples, oranges, and bananas | ||
| - | automatically. Traditionally, the regular classification setup aims at | ||
| - | minimizing the rate of future mis-prediction errors. Nevertheless, in some | ||
| - | applications, it is needed to treat different types of mis-prediction errors | ||
| - | differently. For instance, in a medical decision system, the cost of | ||
| - | mis-predicting a cancerous patient as a healthy one may be higher than | ||
| - | the other way around. In an animal recognition system, the silliness of | ||
| - | mis-predicting a person as a fish may be higher than the silliness of | ||
| - | mis-predicting her/him as a monkey. Such a need can be formalized as the | ||
| - | cost-sensitive classification setup, which is drawing much research attention | ||
| - | because of its many potential applications, including targeted marketing, | ||
| - | fraud detection, and web analysis. | ||
