Induced Model Matching: How Restricted Models Can Help Larger Ones

no code implementations19 Feb 2024 Usama Muneeb, Mesrob I. Ohannessian

We consider scenarios where a very accurate predictive model using restricted features is available at the time of training of a larger, full-featured, model.

Fair Learning with Private Demographic Data

1 code implementation ICML 2020 Hussein Mozannar, Mesrob I. Ohannessian, Nathan Srebro

Sensitive attributes such as race are rarely available to learners in real world settings as their collection is often restricted by laws and regulations.

From Fair Decision Making to Social Equality

no code implementations7 Dec 2018 Hussein Mozannar, Mesrob I. Ohannessian, Nathan Srebro

In this paper, we propose a simple yet revealing model that encompasses (1) a selection process where an institution chooses from multiple groups according to their qualifications so as to maximize an institutional utility and (2) dynamics that govern the evolution of the groups' qualifications according to the imposed policies.

Learning Non-Discriminatory Predictors

no code implementations20 Feb 2017 Blake Woodworth, Suriya Gunasekar, Mesrob I. Ohannessian, Nathan Srebro

We consider learning a predictor which is non-discriminatory with respect to a "protected attribute" according to the notion of "equalized odds" proposed by Hardt et al. [2016].

Tradeoffs for Space, Time, Data and Risk in Unsupervised Learning

no code implementations2 May 2016 Mario Lucic, Mesrob I. Ohannessian, Amin Karbasi, Andreas Krause

Using k-means clustering as a prototypical unsupervised learning problem, we show how we can strategically summarize the data (control space) in order to trade off risk and time when data is generated by a probabilistic model.

no code implementations12 Mar 2015 Elchanan Mossel, Mesrob I. Ohannessian

The probability of this event is referred to as the "missing mass".
