SkipViT: Speeding Up Vision Transformers with a Token-Level Skip Connection

no code implementations27 Jan 2024 Foozhan Ataiefard, Walid Ahmed, Habib Hajimolahoseini, Saina Asani, Farnoosh Javadi, Mohammad Hassanpour, Omar Mohamed Awad, Austin Wen, Kangling Liu, Yang Liu

Our method does not add any parameters to the ViT model and aims to find the best trade-off between training throughput and achieving a 0% loss in the Top-1 accuracy of the final model.

SwiftLearn: A Data-Efficient Training Method of Deep Learning Models using Importance Sampling

no code implementations25 Nov 2023 Habib Hajimolahoseini, Omar Mohamed Awad, Walid Ahmed, Austin Wen, Saina Asani, Mohammad Hassanpour, Farnoosh Javadi, Mehdi Ahmadi, Foozhan Ataiefard, Kangling Liu, Yang Liu

In this paper, we present SwiftLearn, a data-efficient approach to accelerate training of deep learning models using a subset of data samples selected during the warm-up stages of training.

GQKVA: Efficient Pre-training of Transformers by Grouping Queries, Keys, and Values

no code implementations6 Nov 2023 Farnoosh Javadi, Walid Ahmed, Habib Hajimolahoseini, Foozhan Ataiefard, Mohammad Hassanpour, Saina Asani, Austin Wen, Omar Mohamed Awad, Kangling Liu, Yang Liu

We tested our method on ViT, which achieved an approximate 0. 3% increase in accuracy while reducing the model size by about 4% in the task of image classification.

Gray-box Adversarial Attack of Deep Reinforcement Learning-based Trading Agents

no code implementations26 Sep 2023 Foozhan Ataiefard, Hadi Hemmati

In this research, we demonstrate that a "gray-box" approach for attacking a Deep RL-based trading agent is possible by trading in the same stock market, with no extra access to the trading agent.

Deep State Inference: Toward Behavioral Model Inference of Black-box Software Systems

1 code implementation13 Jan 2021 Foozhan Ataiefard, Mohammad Jafar Mashhadi, Hadi Hemmati, Niel Walkinshaw

Many software engineering tasks, such as testing, and anomaly detection can benefit from the ability to infer a behavioral model of the software. Most existing inference approaches assume access to code to collect execution sequences.
