Embedding Hardware Approximations in Discrete Genetic-based Training for Printed MLPs

1 code implementation5 Feb 2024 Florentia Afentaki, Michael Hefenbrock, Georgios Zervakis, Mehdi B. Tahoori

Due to the discrete nature of hardware approximation, we propose and implement a genetic-based, approximate, hardware-aware training approach specifically designed for printed MLPs.

Testing Spintronics Implemented Monte Carlo Dropout-Based Bayesian Neural Networks

no code implementations9 Jan 2024 Soyed Tuhin Ahmed, Michael Hefenbrock, Guillaume Prenat, Lorena Anghel, Mehdi B. Tahoori

Bayesian Neural Networks (BayNNs) can inherently estimate predictive uncertainty, facilitating informed decision-making.

Scale-Dropout: Estimating Uncertainty in Deep Neural Networks Using Stochastic Scale

no code implementations27 Nov 2023 Soyed Tuhin Ahmed, Kamal Danouchi, Michael Hefenbrock, Guillaume Prenat, Lorena Anghel, Mehdi B. Tahoori

In this paper, we propose the Scale Dropout, a novel regularization technique for Binary Neural Networks (BNNs), and Monte Carlo-Scale Dropout (MC-Scale Dropout)-based BayNNs for efficient uncertainty estimation.

Constrained Parameter Regularization

1 code implementation15 Nov 2023 Jörg K. H. Franke, Michael Hefenbrock, Gregor Koehler, Frank Hutter

Instead of applying a single constant penalty to all parameters, we enforce an upper bound on a statistical measure (e. g., the L$_2$-norm) of parameter groups.

Spatial-SpinDrop: Spatial Dropout-based Binary Bayesian Neural Network with Spintronics Implementation

no code implementations16 Jun 2023 Soyed Tuhin Ahmed, Kamal Danouchi, Michael Hefenbrock, Guillaume Prenat, Lorena Anghel, Mehdi B. Tahoori

Furthermore, the number of dropout modules per network layer is reduced by a factor of $9\times$ and energy consumption by a factor of $94. 11\times$, while still achieving comparable predictive performance and uncertainty estimates compared to related works.

Universal Distributional Decision-based Black-box Adversarial Attack with Reinforcement Learning

no code implementations15 Nov 2022 Yiran Huang, Yexu Zhou, Michael Hefenbrock, Till Riedel, Likun Fang, Michael Beigl

In this work, we propose a pixel-wise decision-based attack algorithm that finds a distribution of adversarial perturbation through a reinforcement learning algorithm.

McXai: Local model-agnostic explanation as two games

no code implementations4 Jan 2022 Yiran Huang, Nicole Schaal, Michael Hefenbrock, Yexu Zhou, Till Riedel, Likun Fang, Michael Beigl

Our method leverages Monte Carlo tree search and models the process of generating explanations as two games.
