- Abstract: Display Ads and the generalized assignment problem are two well-studied
online packing problems with important applications in ad allocation and other
areas. In both problems, ad impressions arrive online and have to be allocated
immediately to budget-constrained advertisers. Worst-case algorithms that
achieve the ideal competitive ratio are known, but might act overly
conservative given the predictable and usually tame nature of real-world input.
Given this discrepancy, we develop an algorithm for both problems that
incorporate machine-learned predictions and can thus improve the performance
beyond the worst-case. Our algorithm is based on the work of Feldman et al.
(2009) and similar in nature to Mahdian et al. (2007) who were the first to
develop a learning-augmented algorithm for the related, but more structured Ad
Words problem. We use a novel analysis to show that our algorithm is able to
capitalize on a good prediction, while being robust against poor predictions.
We experimentally evaluate our algorithm on synthetic and real-world data on a
wide range of predictions. Our algorithm is consistently outperforming the
worst-case algorithm without predictions.

Recent advances in algorithmic design show how to utilize predictions obtained by machine learning models from past and present data.
Prior research in this context was focused on a paradigm where the predictor is pre-trained on past data and then used as a black box.
In this work, we unpack the predictor and integrate the learning problem it gives rise for within the algorithmic challenge.

We revisit this well-studied problem in a recently popular learning-augmented setting that integrates (untrusted) predictions in algorithm design.
We show that these predictions have desired properties, admit a natural error measure as well as algorithms with strong performance guarantees.
