A unified model of sequential three-way decisions and multilevel incremental processing

作者：

Highlights：

• We present a general model of sequential three-way decisions by considering seven situations resulted from combinations of three regions.

• We define a general cost for decision process, called the cost of granularity transformation and processing.

• We propose multilevel incremental algorithms to reduce the computation cost.
