in this paper, we develop an inventory model for perishable items with random lifetime in a two-echelon production-distribution system. there is a manufacturer at the first stage that produces its product with a constant rate. deterioration in this stage is modeled via a two-parameter weibull distribution. at the second stage, the retailer places the order and receives the product instantly. th...

In computer vision, it has achieved great transfer learning performance via adapting large-scale pretrained vision models (e.g., transformers) to downstream tasks. Common approaches for model adaptation either update all parameters or leverage linear probes. this paper, we aim study parameter-efficient strategies transformers on the image classification task. We formulate efficient as a subspac...
