Diagnosing Catastrophe: Large parts of accuracy loss in continual learning can be accounted for by readout misalignment

no code implementations9 Oct 2023 Daniel Anthes, Sushrut Thorat, Peter König, Tim C. Kietzmann

Unlike primates, training artificial neural networks on changing data distributions leads to a rapid decrease in performance on old tasks.

Characterising representation dynamics in recurrent neural networks for object recognition

no code implementations23 Aug 2023 Sushrut Thorat, Adrien Doerig, Tim C. Kietzmann

Recurrent neural networks (RNNs) have yielded promising results for both recognizing objects in challenging conditions and modeling aspects of primate vision.

Object Recognition

The neuroconnectionist research programme

no code implementations8 Sep 2022 Adrien Doerig, Rowan Sommers, Katja Seeliger, Blake Richards, Jenann Ismael, Grace Lindsay, Konrad Kording, Talia Konkle, Marcel A. J. van Gerven, Nikolaus Kriegeskorte, Tim C. Kietzmann

Artificial Neural Networks (ANNs) inspired by biology are beginning to be widely used to model behavioral and neural data, an approach we call neuroconnectionism.

Category-orthogonal object features guide information processing in recurrent neural networks trained for object categorization

1 code implementation NeurIPS Workshop SVRHM 2021 Sushrut Thorat, Giacomo Aldegheri, Tim C. Kietzmann

Recurrent neural networks (RNNs) have been shown to perform better than feedforward architectures in visual object categorization tasks, especially in challenging conditions such as cluttered images.

An ecologically motivated image dataset for deep learning yields better models of human vision

no code implementations15 Feb 2021 Johannes Mehrer, Courtney J. Spoerer, Emer C. Jones, Nikolaus Kriegeskorte, Tim C. Kietzmann

This dataset comprises images from 1, 000 categories, selected to provide a challenging testbed for automated visual object recognition systems.

Object Recognition

Learning robust visual representations using data augmentation invariance

1 code implementation11 Jun 2019 Alex Hernández-García, Peter König, Tim C. Kietzmann

Deep convolutional neural networks trained for image object categorization have shown remarkable similarities with representations found across the primate ventral visual stream.

Recurrence is required to capture the representational dynamics of the human visual system

no code implementations14 Mar 2019 Tim C. Kietzmann, Courtney J Spoerer, Lynn Sörensen, Radoslaw M. Cichy, Olaf Hauk, Nikolaus Kriegeskorte

Here, we measure and model the rapid representational dynamics across multiple stages of the human ventral stream using time-resolved brain imaging and deep learning.
