Query: Contextual Bandits for Advertising Campaigns: A Diffusion-Model
  Independent Approach (Extended Version)   Motivated by scenarios of information diffusion and advertising in social
media, we study an influence maximization problem in which little is assumed to
be known about the diffusion network or about the model that determines how
information may propagate. In such a highly uncertain environment, one can
focus on multi-round diffusion campaigns, with the objective to maximize the
number of distinct users that are influenced or activated, starting from a
known base of few influential nodes. During a campaign, spread seeds are
selected sequentially at consecutive rounds, and feedback is collected in the
form of the activated nodes at each round. A round's impact (reward) is then
quantified as the number of newly activated nodes. Overall, one must maximize
the campaign's total spread, as the sum of rounds' rewards. In this setting, an
explore-exploit approach could be used to learn the key underlying diffusion
parameters, while running the campaign. We describe and compare two methods of
contextual multi-armed bandits, with upper-confidence bounds on the remaining
potential of influencers, one using a generalized linear model and the
Good-Turing estimator for remaining potential (GLM-GT-UCB), and another one
that directly adapts the LinUCB algorithm to our setting (LogNorm-LinUCB). We
show that they outperform baseline methods using state-of-the-art ideas, on
synthetic and real-world data, while at the same time exhibiting different and
complementary behavior, depending on the scenarios in which they are deployed.
