Influencing Bandits: Arm Selection for Preference Shaping

no code implementations29 Feb 2024 Viraj Nadkarni, D. Manjunath, Sharayu Moharir

For the case of binary opinions, two types of opinion dynamics are considered -- decreasing elasticity (modeled as a Polya urn with increasing number of balls) and constant elasticity (using the voter model).

On the Regret of Online Edge Service Hosting

no code implementations13 Mar 2023 R Sri Prakash, Nikhil Karamchandani, Sharayu Moharir

The total cost incurred by the system is modeled as a combination of the rent cost, the service cost incurred due to latency in serving customers, and the fetch cost incurred as a result of the bandwidth used to fetch the code/databases of the service from the cloud servers to host the service at the edge.

Multi-Model Federated Learning with Provable Guarantees

no code implementations9 Jul 2022 Neelkamal Bhuyan, Sharayu Moharir, Gauri Joshi

Federated Learning (FL) is a variant of distributed learning where edge devices collaborate to learn a model without sharing their data with the central server or each other.

Multi-Model Federated Learning

no code implementations7 Jan 2022 Neelkamal Bhuyan, Sharayu Moharir

Specifically, every client is able to train any one of M models at a time and the server maintains a model for each of the M models which is typically a suitably averaged version of the model computed by the clients.

Online Partial Service Hosting at the Edge

no code implementations28 Feb 2021 V S Ch Lakshmi Narayana, Mohit Agarwala, Nikhil Karamchandani, Sharayu Moharir

We propose an online policy called $\alpha$-RetroRenting ($\alpha$-RR) which dynamically determines the fraction of the service to be hosted at the edge in any time-slot, based on the history of the request arrivals and the rent cost sequence.

Greedy k-Center from Noisy Distance Samples

no code implementations3 Nov 2020 Neharika Jali, Nikhil Karamchandani, Sharayu Moharir

We study a variant of the canonical k-center problem over a set of vertices in a metric space, where the underlying distances are apriori unknown.

Dynamic social learning under graph constraints

no code implementations8 Jul 2020 Konstantin Avrachenkov, Vivek S. Borkar, Sharayu Moharir, Suhail M. Shah

We introduce a model of graph-constrained dynamic choice with reinforcement modeled by positively $\alpha$-homogeneous rewards.

Contextual Bandits Evolving Over Finite Time

no code implementations14 Nov 2019 Harsh Deshpande, Vishal Jain, Sharayu Moharir

Contextual bandits have the same exploration-exploitation trade-off as standard multi-armed bandits.

Multi-Armed Bandits

Request Patterns and Caching for VoD Services with Recommendation Systems

no code implementations8 Sep 2016 Samarth Gupta, Sharayu Moharir

We propose a Markovian request model to capture the time-correlation in user requests and show that our model is consistent with the observations of existing empirical studies.
