KDD 2023 ACM SIGKDD Workshop on Causal Discovery, Prediction and Decision (CDPD)2023Companies offering web services routinely run randomized online experiments to estimate the “causal impact” associated with the adoption of new features and policies on key performance metrics of interest. These experiments are used to estimate a variety of effects: the increase in click rate due to the repositioning of a banner, the impact on subscription rate as a consequence of a discount or special

ICLR 2023 Tiny Papers2023We present a novel strategy to generate learned learning rate schedules for any optimizer using reinforcement learning (RL). Our approach trains a Proximal Policy Optimization (PPO) agent to predict optimal learning rate schedules for SGD, which we compare with other optimizer-scheduler combinations and full grid search. Our experiments show that the agent learns to generate dynamic schedules that result

ICLR 2023 Tiny Papers2023For deep learning training, learning rate schedules are often picked through trial and error, or hand-crafted optimization algorithms that focus mostly on maintaining stability and convergence without systemic incorporation of higher order derivative information to optimize the convergence slope. In this paper, we consider a stochastic version of Non-negative Matrix Factorization (NMF) where only a noisy

ICML 20232023We study efficient mechanisms for differentially private kernel density estimation (DP-KDE). Prior work for the Gaussian kernel described algorithms that run in time exponential in the number of dimensions d. This paper breaks the exponential barrier, and shows how the KDE can privately be approximated in time linear in d, making it feasible for high-dimensional data. We also present improved bounds for

ACL 20232023Bias in machine learning models can be an issue when the models are trained on particular types of data that do not generalize well, causing under performance in certain groups of users. In this work, we focus on reducing the bias related to new customers in a digital voice assistant system. It is observed that natural language understanding models often have lower performance when dealing with requests
