LACS: Learning-Augmented Algorithms for Carbon-Aware Resource Scaling with Uncertain Demand

no code implementations29 Mar 2024 Roozbeh Bostandoost, Adam Lechowicz, Walid A. Hanafy, Noman Bashir, Prashant Shenoy, Mohammad Hajiesmaili

The task is to dynamically scale resources (e. g., the number of servers) assigned to a job of unknown length such that it is completed before a deadline, with the objective of reducing the carbon emissions of executing the workload.

Online Conversion with Switching Costs: Robust and Learning-Augmented Algorithms

1 code implementation31 Oct 2023 Adam Lechowicz, Nicolas Christianson, Bo Sun, Noman Bashir, Mohammad Hajiesmaili, Adam Wierman, Prashant Shenoy

We introduce competitive (robust) threshold-based algorithms for both the minimization and maximization variants of this problem, and show they are optimal among deterministic online algorithms.

Time Fairness in Online Knapsack Problems

1 code implementation22 May 2023 Adam Lechowicz, Rik Sengupta, Bo Sun, Shahin Kamali, Mohammad Hajiesmaili

We propose a parameterized deterministic algorithm where the parameter precisely captures the Pareto-optimal trade-off between fairness (static pricing) and competitiveness (dynamic pricing).

FlowSense: Monitoring Airflow in Building Ventilation Systems Using Audio Sensing

1 code implementation22 Feb 2022 Bhawana Chhaglani, Camellia Zakaria, Adam Lechowicz, Prashant Shenoy, Jeremy Gummeson

With a motivation to monitor airflow from building ventilation systems through commodity sensing devices, we present FlowSense, a machine learning-based algorithm to predict airflow rate from sensed audio data in indoor spaces.
