Query: Collaborative Machine Learning with Incentive-Aware Model Rewards   Collaborative machine learning (ML) is an appealing paradigm to build
high-quality ML models by training on the aggregated data from many parties.
However, these parties are only willing to share their data when given enough
incentives, such as a guaranteed fair reward based on their contributions. This
motivates the need for measuring a party's contribution and designing an
incentive-aware reward scheme accordingly. This paper proposes to value a
party's reward based on Shapley value and information gain on model parameters
given its data. Subsequently, we give each party a model as a reward. To
formally incentivize the collaboration, we define some desirable properties
(e.g., fairness and stability) which are inspired by cooperative game theory
but adapted for our model reward that is uniquely freely replicable. Then, we
propose a novel model reward scheme to satisfy fairness and trade off between
the desirable properties via an adjustable parameter. The value of each party's
model reward determined by our scheme is attained by injecting Gaussian noise
to the aggregated training data with an optimized noise variance. We
empirically demonstrate interesting properties of our scheme and evaluate its
performance using synthetic and real-world datasets.
