Shapley Value & Cooperative Game Theory

Towards Efficient Data Valuation Based on the Shapley Value	Ruoxi Jia & David Dao, Boxin Wang, Frances Ann Hubis, Nick Hynes, Nezihe Merve Gürel, Bo Li, Ce Zhang, Dawn Song, Costas J. Spanos	2019	Summary Jia et al. (2019) contribute theoretical and practical results for efficient methods for approximating the Shapley value (SV). They show that methods with a sublinear amount of model evaluations are possible and further reductions can be made for sparse SVs. Lastly, they introduce two practical SV estimation methods for ML tasks, one for uniformly stable learning algorithms and one for smooth loss functions.

Efficient and Fair Data Valuation for Horizontal Federated Learning	Shuyue Wei, Yongxin Tong, Zimu Zhou, Tianshu Song	2020	Summary Availability of big data is crucial for modern machine learning applications and services. Federated learning is an emerging paradigm to unite different data owners for machine learning on massive data sets without worrying about data privacy. Yet data owners may still be reluctant to contribute unless their data sets are fairly valuated and paid. In this work, the authors adapt Shapley value, a widely used data valuation metric to valuating data providers in federated learning. Prior data valuation schemes for machine learning incur high computation cost because they require training of extra models on all data set combinations. For efficient data valuation, the authors approximately construct all the models necessary for data valuation using the gradients in training a single model, rather than train an exponential number of models from scratch. On this basis, they devise three methods for efficient contribution index estimation. Evaluations show that their methods accurately approximate the contribution index while notably accelerating its calculation.

SaFE approximates the Shapley value using gradients from training a single model and develops methods for efficient contribution index estimation.

Strategic adaptation

Performative prediction

Performative Prediction	Juan Perdomo, Tijana Zrnic, Celestine Mendler-Dünner, Moritz Hardt	2020	Summary Perdomo et al. (2020) introduce the concept of "performative prediction" dealing with predictions that influence the target they aim to predict, e.g. through taking actions based on the predictions, causing a distribution shift. The authors develop a risk minimization framework for performative prediction and introduce the equilibrium notion of performative stability where predictions are calibrated against future outcomes that manifest from acting on the prediction.

Stochastic Optimization for Performative Prediction	Celestine Mendler-Dünner, Juan Perdomo, Tijana Zrnic, Moritz Hardt	2020	Summary Mendler-Dünner et al. (2020) look at stochastic optimization for performative prediction and prove convergence rates for greedily deploying models after each stochastic update (which may cause distribution shift affecting convergence to a stability point) or lazily deploying the model after several updates.

Strategic classification

Strategic Classification is Causal Modeling in Disguise	John Miller, Smitha Milli, Moritz Hardt	2020	Summary Miller et al. (2020) argue that strategic classication involves causal modelling and designing incentives for improvement requires solving a non-trivial causal inference problem. The authors provide a distinction between gaming and improvement as well as provide a causal framework for strategic adaptation.

Alternative Microfoundations for Strategic Classification	Meena Jagadeesan, Celestine Mendler-Dünner, Moritz Hardt	2021	Summary Jagadeesan et al. (2021) show that standard microfoundations in strategic classification, that typically uses individual-level behaviour to deduce aggregate-level responses, can lead to degenerate behaviour in aggregate: discontinuities in the aggregate response, stable points ceasing to exist, and maximizing social burden. The authors introduce a noisy response model inspired by performative prediction that mitigates these limitations for binary classification.
