Improving Analog Neural Network Robustness: A Noise-Agnostic Approach with Explainable Regularizations
Alice Duque, Pedro Freire, Egor Manuylovich +3
This work tackles the critical challenge of mitigating "hardware noise" in deep analog neural networks, a major obstacle in advancing analog signal processing devices. We propose a…
Uncovering Latent Human Wellbeing in Language Model Embeddings
Pedro Freire, ChengCheng Tan, Adam Gleave +2
Do language models implicitly learn a concept of human wellbeing? We explore this through the ETHICS Utilitarianism task, assessing if scaling enhances pretrained models' represent…
Hardware Realization of Nonlinear Activation Functions for NN-based Optical Equalizers
Sasipim Srivallapanondh, Pedro J. Freire, Antonio Napoli +2
To reduce the complexity of the hardware implementation of neural network-based optical channel equalizers, we demonstrate that the performance of the biLSTM equalizer with approxi…
