Optimal Sequential Maximization: One Interview is Enough!

no code implementations ICML 2020 Moein Falahatgar, Alon Orlitsky, Venkatadheeraj Pichapati

To derive these results we consider a probabilistic setting where several candidates for a position are asked multiple questions with the goal of finding who has the highest probability of answering interview questions correctly.

AdaCliP: Adaptive Clipping for Private SGD

1 code implementation20 Aug 2019 Venkatadheeraj Pichapati, Ananda Theertha Suresh, Felix X. Yu, Sashank J. Reddi, Sanjiv Kumar

Motivated by this, differentially private stochastic gradient descent (SGD) algorithms for training machine learning models have been proposed.

On Learning Markov Chains

no code implementations NeurIPS 2018 Yi Hao, Alon Orlitsky, Venkatadheeraj Pichapati

We consider two problems related to the min-max risk (expected loss) of estimating an unknown $k$-state Markov chain from its $n$ sequential samples: predicting the conditional distribution of the next sample with respect to the KL-divergence, and estimating the transition matrix with respect to a natural loss induced by KL or a more general $f$-divergence measure.

The Limits of Maxing, Ranking, and Preference Learning

no code implementations ICML 2018 Moein Falahatgar, Ayush Jain, Alon Orlitsky, Venkatadheeraj Pichapati, Vaishakh Ravindrakumar

We present a comprehensive understanding of three important problems in PAC preference learning: maximum selection (maxing), ranking, and estimating all pairwise preference probabilities, in the adaptive setting.

Maxing and Ranking with Few Assumptions

no code implementations NeurIPS 2017 Moein Falahatgar, Yi Hao, Alon Orlitsky, Venkatadheeraj Pichapati, Vaishakh Ravindrakumar

PAC maximum selection (maxing) and ranking of $n$ elements via random pairwise comparisons have diverse applications and have been studied under many models and assumptions.

Maximum Selection and Ranking under Noisy Comparisons

no code implementations ICML 2017 Moein Falahatgar, Alon Orlitsky, Venkatadheeraj Pichapati, Ananda Theertha Suresh

We consider $(\epsilon,\delta)$-PAC maximum-selection and ranking for general probabilistic models whose comparisons probabilities satisfy strong stochastic transitivity and stochastic triangle inequality.
