RIM allows us to rethink recommendation in a Matching (Mtch) scenario, where the benefits of the users (e. g., ItemRec relevance) and item providers (e. g., item-exposure guarantees) are considered at the same time.

We introduce the maximum $n$-times coverage problem that selects $k$ overlays to maximize the summed coverage of weighted elements, where each element must be covered at least $n$ times.

We introduce Information Condensing Active Learning (ICAL), a batch mode model agnostic Active Learning (AL) method targeted at Deep Bayesian Active Learning that focuses on acquiring labels for points which have as much information as possible about the still unacquired points.

The inaccuracy of neural network models on inputs that do not stem from the training data distribution is both problematic and at times unrecognized.
