Continual Facial Expression Recognition: A Benchmark

no code implementations10 May 2023 Nikhil Churamani, Tolga Dimlioglu, German I. Parisi, Hatice Gunes

Understanding human affective behaviour, especially in the dynamics of real-world settings, requires Facial Expression Recognition (FER) models to continuously adapt to individual differences in user expression, contextual attributions, and the environment.

Rethinking Continual Learning for Autonomous Agents and Robots

no code implementations2 Jul 2019 German I. Parisi, Christopher Kanan

Continual learning refers to the ability of a biological or artificial system to seamlessly learn from continuous streams of information while preventing catastrophic forgetting, i. e., a condition in which new incoming information strongly interferes with previously learned representations.

Lifelong Learning of Spatiotemporal Representations with Dual-Memory Recurrent Self-Organization

1 code implementation28 May 2018 German I. Parisi, Jun Tani, Cornelius Weber, Stefan Wermter

Both growing networks can expand in response to novel sensory experience: the episodic memory learns fine-grained spatiotemporal representations of object instances in an unsupervised fashion while the semantic memory uses task-relevant signals to regulate structural plasticity levels and develop more compact representations from episodic experience.

Closing the loop on multisensory interactions: A neural architecture for multisensory causal inference and recalibration

no code implementations19 Feb 2018 Jonathan Tong, German I. Parisi, Stefan Wermter, Brigitte Röder

Furthermore, we propose that these unisensory and multisensory neurons play dual roles in i) encoding spatial location as separate or integrated estimates and ii) accumulating evidence for the independence or relatedness of multisensory stimuli.
