Sample Weight Estimation Using Meta-Updates for Online Continual Learning

1 code implementation29 Jan 2024 Hamed Hemati, Damian Borth

This is done by first estimating sample weight parameters for each sample in the mini-batch, then, updating the model with the adapted sample weights.

A Comprehensive Empirical Evaluation on Online Continual Learning

2 code implementations20 Aug 2023 Albin Soutif--Cormerais, Antonio Carta, Andrea Cossu, Julio Hurtado, Hamed Hemati, Vincenzo Lomonaco, Joost Van de Weijer

Online continual learning aims to get closer to a live learning experience by learning directly on a stream of data with temporally shifting distribution and by storing a minimum amount of data from that stream.

Partial Hypernetworks for Continual Learning

1 code implementation19 Jun 2023 Hamed Hemati, Vincenzo Lomonaco, Davide Bacciu, Damian Borth

Inspired by latent replay methods in CL, we propose partial weight generation for the final layers of a model using hypernetworks while freezing the initial layers.

Avalanche: A PyTorch Library for Deep Continual Learning

1 code implementation2 Feb 2023 Antonio Carta, Lorenzo Pellegrini, Andrea Cossu, Hamed Hemati, Vincenzo Lomonaco

Continual learning is the problem of learning from a nonstationary stream of data, a fundamental issue for sustainable and efficient training of deep neural networks over time.

Class-Incremental Learning with Repetition

1 code implementation26 Jan 2023 Hamed Hemati, Andrea Cossu, Antonio Carta, Julio Hurtado, Lorenzo Pellegrini, Davide Bacciu, Vincenzo Lomonaco, Damian Borth

We propose two stochastic stream generators that produce a wide range of CIR streams starting from a single dataset and a few interpretable control parameters.

Federated Continual Learning to Detect Accounting Anomalies in Financial Auditing

no code implementations26 Oct 2022 Marco Schreyer, Hamed Hemati, Damian Borth, Miklos A. Vasarhelyi

Our empirical results, using real-world datasets and combined federated continual learning strategies, demonstrate the learned model's ability to detect anomalies in audit settings of data distribution shifts.

Continual Speaker Adaptation for Text-to-Speech Synthesis

no code implementations26 Mar 2021 Hamed Hemati, Damian Borth

The naive solution of sequential fine-tuning of a model for new speakers can lead to poor performance of older speakers.

Using IPA-Based Tacotron for Data Efficient Cross-Lingual Speaker Adaptation and Pronunciation Enhancement

no code implementations12 Nov 2020 Hamed Hemati, Damian Borth

Recent neural Text-to-Speech (TTS) models have been shown to perform very well when enough data is available.
