Lookbehind-SAM: k steps back, 1 step forward

Gonçalo Mordido, Pranshu Malviya, Aristide Baratin +1

Sharpness-aware minimization (SAM) methods have gained increasing popularity by formulating the problem of minimizing both loss value and loss sharpness as a minimax objective. In…

Promoting Exploration in Memory-Augmented Adam using Critical Momenta

Pranshu Malviya, Gonçalo Mordido, Aristide Baratin +5

Adaptive gradient-based optimizers, notably Adam, have left their mark in training large-scale deep learning models, offering fast convergence and robustness to hyperparameter sett…

Should We Attend More or Less? Modulating Attention for Fairness

Abdelrahman Zayed, Goncalo Mordido, Samira Shabanian +1

The advances in natural language processing (NLP) pose both opportunities and challenges. While recent progress enables the development of high-performing models for a variety of t…

Deep Learning on a Healthy Data Diet: Finding Important Examples for Fairness

Abdelrahman Zayed, Prasanna Parthasarathi, Goncalo Mordido +3

Data-driven predictive solutions predominant in commercial applications tend to suffer from biases and stereotypes, which raises equity concerns. Prediction models may discover, us…

SAMSON: Sharpness-Aware Minimization Scaled by Outlier Normalization for Improving DNN Generalization and Robustness

Gonçalo Mordido, Sébastien Henwood, Sarath Chandar +1

Energy-efficient deep neural network (DNN) accelerators are prone to non-idealities that degrade DNN performance at inference time. To mitigate such degradation, existing methods t…

Improving Meta-Learning Generalization with Activation-Based Early-Stopping

Simon Guiroy, Christopher Pal, Gonçalo Mordido +1

Meta-Learning algorithms for few-shot learning aim to train neural networks capable of generalizing to novel tasks using only a few examples. Early-stopping is critical for perform…

MemSE: Fast MSE Prediction for Noisy Memristor-Based DNN Accelerators

Jonathan Kern, Sébastien Henwood, Gonçalo Mordido +4

Memristors enable the computation of matrix-vector multiplications (MVM) in memory and, therefore, show great potential in highly increasing the energy efficiency of deep neural ne…

Compressing 1D Time-Channel Separable Convolutions using Sparse Random Ternary Matrices

Gonçalo Mordido, Matthijs Van Keirsbilck, Alexander Keller

We demonstrate that 1x1-convolutions in 1D time-channel separable convolutions may be replaced by constant, sparse random ternary matrices with weights in . Such layer…

Evaluating Post-Training Compression in GANs using Locality-Sensitive Hashing

Gonçalo Mordido, Haojin Yang, Christoph Meinel

The analysis of the compression effects in generative adversarial networks (GANs) after training, i.e. without any fine-tuning, remains an unstudied, albeit important, topic with t…

Mark-Evaluate: Assessing Language Generation using Population Estimation Methods

Gonçalo Mordido, Christoph Meinel

We propose a family of metrics to assess language generation derived from population estimation methods widely used in ecology. More specifically, we use mark-recapture and maximum…

Improving the Evaluation of Generative Models with Fuzzy Logic

Julian Niedermeier, Gonçalo Mordido, Christoph Meinel

Objective and interpretable metrics to evaluate current artificial intelligent systems are of great importance, not only to analyze the current state of such systems but also to ob…

microbatchGAN: Stimulating Diversity with Multi-Adversarial Discrimination

Gonçalo Mordido, Haojin Yang, Christoph Meinel

We propose to tackle the mode collapse problem in generative adversarial networks (GANs) by using multiple discriminators and assigning a different portion of each minibatch, calle…

Instant Quantization of Neural Networks using Monte Carlo Methods

Gonçalo Mordido, Matthijs Van Keirsbilck, Alexander Keller

Low bit-width integer weights and activations are very important for efficient inference, especially with respect to lower power consumption. We propose Monte Carlo methods to quan…

Dropout-GAN: Learning from a Dynamic Ensemble of Discriminators

Gonçalo Mordido, Haojin Yang, Christoph Meinel

We propose to incorporate adversarial dropout in generative multi-adversarial networks, by omitting or dropping out, the feedback of each discriminator in the framework with some p…

Automatic Organisation, Segmentation, and Filtering of User-Generated Audio Content

Gonçalo Mordido, João Magalhães, Sofia Cavaco

Using solely the information retrieved by audio fingerprinting techniques, we propose methods to treat a possibly large dataset of user-generated audio content, that (1) enable the…

Automatic Organisation and Quality Analysis of User-Generated Content with Audio Fingerprinting

Gonçalo Mordido, João Magalhães, Sofia Cavaco

The increase of the quantity of user-generated content experienced in social media has boosted the importance of analysing and organising the content by its quality. Here, we propo…
