Shrinking the Upper Confidence Bound: A Dynamic Product Selection Problem for Urban Warehouses
[article]
2019
arXiv
pre-print
Preserved Fulltext
Other Versions
To reduce the fixed cost for large K values, we propose a novel online learning algorithm, which iteratively shrinks the upper confidence bounds within each period, and show its fixed cost is reduced by ...
The space limit in urban warehouses poses a problem for the online retailers: the number of products (SKUs) they carry is no longer "the more, the better", yet it can still be significantly large, reaching ...
It shows that, under ConsUCB, the regret per product selection can be upper-bounded by the sum of a standard confidence interval term and the increase in the lower confidence bound of a product in the ...
