Machine Learning-Aided Efficient Decoding of Reed-Muller Subcodes

no code implementations16 Jan 2023 Mohammad Vahid Jamali, Xiyang Liu, Ashok Vardhan Makkuva, Hessam Mahdavifar, Sewoong Oh, Pramod Viswanath

Next, we derive the soft-decision based version of our algorithm, called soft-subRPA, that not only improves upon the performance of subRPA but also enables a differentiable decoding algorithm.

Federated Learning with Heterogeneous Differential Privacy

no code implementations28 Oct 2021 Nasser Aldaghri, Hessam Mahdavifar, Ahmad Beirami

We propose a new algorithm for FL with heterogeneous DP, named FedHDP, which employs personalization and weighted averaging at the server using the privacy choices of clients, to achieve better performance on clients' local models.

ApproxIFER: A Model-Agnostic Approach to Resilient and Robust Prediction Serving Systems

no code implementations20 Sep 2021 Mahdi Soleymani, Ramy E. Ali, Hessam Mahdavifar, A. Salman Avestimehr

While this learning-based approach is more resource-efficient than replication, it is tailored to the specific model hosted by the cloud and is particularly suitable for a small number of queries (typically less than four) and tolerating very few (mostly one) number of stragglers.

KO codes: Inventing Nonlinear Encoding and Decoding for Reliable Wireless Communication via Deep-learning

1 code implementation29 Aug 2021 Ashok Vardhan Makkuva, Xiyang Liu, Mohammad Vahid Jamali, Hessam Mahdavifar, Sewoong Oh, Pramod Viswanath

In this paper, we construct KO codes, a computationaly efficient family of deep-learning driven (encoder, decoder) pairs that outperform the state-of-the-art reliability performance on the standardized AWGN channel.

Reed-Muller Subcodes: Machine Learning-Aided Design of Efficient Soft Recursive Decoding

no code implementations2 Feb 2021 Mohammad Vahid Jamali, Xiyang Liu, Ashok Vardhan Makkuva, Hessam Mahdavifar, Sewoong Oh, Pramod Viswanath

To lower the complexity of our decoding algorithm, referred to as subRPA in this paper, we investigate different ways for pruning the projections.

List-Decodable Coded Computing: Breaking the Adversarial Toleration Barrier

no code implementations27 Jan 2021 Mahdi Soleymani, Ramy E. Ali, Hessam Mahdavifar, A. Salman Avestimehr

We further propose folded Lagrange coded computing (FLCC) to incorporate the developed techniques into a specific coded computing setting.

Coded Machine Unlearning

Coding for Crowdsourced Classification with XOR Queries

no code implementations25 Jun 2019 James Chin-Jen Pang, Hessam Mahdavifar, S. Sandeep Pradhan

In this paper we leverage the connections between this problem and well-studied codes with sparse representations for the channel coding problem to provide querying schemes with almost optimal number of queries, each of which involving only a constant number of labels.
