Inference Offloading for Cost-Sensitive Binary Classification at the Edge

Vishnu Narayanan Moothedath, Umang Agarwal, Umeshraja N +3

We focus on a binary classification problem in an edge intelligence system where false negatives are more costly than false positives. The system has a compact, locally deployed mo…

Low-Regret and Low-Complexity Learning for Hierarchical Inference

Sameep Chattopadhyay, Vinay Sutar, Jaya Prakash Champati +1

This work focuses on Hierarchical Inference (HI) in edge intelligence systems, where a compact Local-ML model on an end-device works in conjunction with a high-accuracy Remote-ML m…

Fixed-Confidence Best Arm Identification with Decreasing Variance

Tamojeet Roychowdhury, Kota Srinivas Reddy, Krishna P Jagannathan +1

We focus on the problem of best-arm identification in a stochastic multi-arm bandit with temporally decreasing variances for the arms' rewards. We model arm rewards as Gaussian ran…

Constrained Best Arm Identification in Grouped Bandits

Sahil Dharod, Malyala Preethi Sravani, Sakshi Heda +1

We study a grouped bandit setting where each arm comprises multiple independent sub-arms referred to as attributes. Each attribute of each arm has an independent stochastic reward.…
