[1] Heterogeneous Values of One Data Point: Active Label Acquisition in Assortment Optimization
Mo Liu, Junyu Cao, Zuo-jun Max Shen. To be resubmitted to Management Science. [link] [Slides]
“How much is the marginal contribution to the revenue increase when adding one new customer with some specific feature into the training set?”
By evaluating this marginal contribution of each customer, we are able to identify informative customers and reduce the size of the training set by about 80% percent while maintaining the same level of revenue.
