You Too Can Save Loads of Money: The Details of the Bayesian Model
- Gravityloss 12y agoSince the graph only has variables and the explanations are mentioned in the text, you have to keep cross referencing.
- jessaustin 12y agoIf the authors see this, I'd be interested to learn what MCMC package they use.
- ubergmann 12y agowe used our own C++ multi-threaded Gibbs sampler, which turned out to mix fast enough for the estimation - even given the large number of parcels/items we have at Zalando
- psychometry 12y agoDoes their cost/benefit analysis incorporate the cost of paying data scientists to build these models? I'm really confused as to how the weight of a SKU is not information that's readily available to them from the manufacturer, or why a missing weight can't be determined as part of the fulfillment process. After all, you only need to weigh a SKU once, so it's only a problem the first time that item is packed. You'd think knowing the weights of products in your warehouse would be a solved problem by 3PLs and not one requiring the services of people with graduate degrees in statistics.
