Amazon SageMaker Model Parallelism: A General and Flexible Framework for Large Model Training

no code implementations10 Nov 2021 Can Karakus, Rahul Huilgol, Fei Wu, Anirudh Subramanian, Cade Daniel, Derya Cavdar, Teng Xu, Haohan Chen, Arash Rahnama, Luis Quintela

In contrast to existing solutions, the implementation of the SageMaker library is much more generic and flexible, in that it can automatically partition and run pipeline parallelism over arbitrary model architectures with minimal code change, and also offers a general and extensible framework for tensor parallelism, which supports a wider range of use cases, and is modular enough to be easily applied to new training scripts.

An Adversarial Approach for Explaining the Predictions of Deep Neural Networks

2 code implementations20 May 2020 Arash Rahnama, Andrew Tseng

In this work, we present a novel algorithm for explaining the predictions of a DNN using adversarial machine learning.

Robust Design of Deep Neural Networks against Adversarial Attacks based on Lyapunov Theory

1 code implementation CVPR 2020 Arash Rahnama, Andre T. Nguyen, Edward Raff

We treat each individual layer of the DNN as a nonlinear dynamical system and use Lyapunov theory to prove stability and robustness locally.

Connecting Lyapunov Control Theory to Adversarial Attacks

no code implementations17 Jul 2019 Arash Rahnama, Andre T. Nguyen, Edward Raff

Significant work is being done to develop the math and tools necessary to build provable defenses, or at least bounds, against adversarial attacks of neural networks.

Resilient Learning-Based Control for Synchronization of Passive Multi-Agent Systems under Attack

no code implementations28 Sep 2017 Arash Rahnama, Panos J. Antsaklis

We define a general Byzantine attack on the event-triggered multi-agent network system and characterize its negative effects on synchronization.

Encoding Multi-Resolution Brain Networks Using Unsupervised Deep Learning

no code implementations13 Aug 2017 Arash Rahnama, Abdullah Alchihabi, Vijay Gupta, Panos Antsaklis, Fatos T. Yarman Vural

We suggest a deep architecture which learns the natural groupings of the connectivity patterns of human brain in multiple time-resolutions.
