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.

Explainable 3D Convolutional Neural Networks by Learning Temporal Transformations

no code implementations29 Jun 2020 Gabriëlle Ras, Luca Ambrogioni, Pim Haselager, Marcel A. J. van Gerven, Umut Güçlü

Finally, we implicitly demonstrate that, in popular ConvNets, the 2DConv can be replaced with a 3TConv and that the weights can be transferred to yield pretrained 3TConvs.

GAIT-prop: A biologically plausible learning rule derived from backpropagation of error

1 code implementation NeurIPS 2020 Nasir Ahmad, Marcel A. J. van Gerven, Luca Ambrogioni

An alternative called target propagation proposes to solve this implausibility by using a top-down model of neural activity to convert an error at the output of a neural network into layer-wise and plausible 'targets' for every unit.

Overcoming the Weight Transport Problem via Spike-Timing-Dependent Weight Inference

1 code implementation9 Mar 2020 Nasir Ahmad, Luca Ambrogioni, Marcel A. J. van Gerven

We propose a solution to the weight transport problem, which questions the biological plausibility of the backpropagation algorithm.

Background Hardly Matters: Understanding Personality Attribution in Deep Residual Networks

no code implementations20 Dec 2019 Gabriëlle Ras, Ron Dotsch, Luca Ambrogioni, Umut Güçlü, Marcel A. J. van Gerven

It is important that we understand the driving factors behind the predictions, in humans and in deep neural networks.

Temporal Factorization of 3D Convolutional Kernels

no code implementations9 Dec 2019 Gabriëlle Ras, Luca Ambrogioni, Umut Güçlü, Marcel A. J. van Gerven

3D convolutional neural networks are difficult to train because they are parameter-expensive and data-hungry.

Bayesian nonparametric discontinuity design

1 code implementation15 Nov 2019 Max Hinne, David Leeftink, Marcel A. J. van Gerven, Luca Ambrogioni

Quasi-experimental research designs, such as regression discontinuity and interrupted time series, allow for causal inference in the absence of a randomized controlled trial, at the cost of additional assumptions.

Modulation of early visual processing alleviates capacity limits in solving multiple tasks

1 code implementation29 Jul 2019 Sushrut Thorat, Giacomo Aldegheri, Marcel A. J. van Gerven, Marius V. Peelen

In daily life situations, we have to perform multiple tasks given a visual stimulus, which requires task-relevant information to be transmitted through our visual system.

Furthermore, we introduce a family of variance reduction techniques that can be applied to other gradient estimators.

Variational Inference

Wasserstein Variational Inference

no code implementations NeurIPS 2018 Luca Ambrogioni, Umut Güçlü, Yağmur Güçlütürk, Max Hinne, Eric Maris, Marcel A. J. van Gerven

This paper introduces Wasserstein variational inference, a new form of approximate Bayesian inference based on optimal transport theory.

Reconstructing perceived faces from brain activations with deep adversarial neural decoding

no code implementations NeurIPS 2017 Yağmur Güçlütürk, Umut Güçlü, Katja Seeliger, Sander Bosch, Rob Van Lier, Marcel A. J. van Gerven

Here, we present a novel approach to solve the problem of reconstructing perceived stimuli from brain responses by combining probabilistic inference with deep learning.

The Kernel Mixture Network: A Nonparametric Method for Conditional Density Estimation of Continuous Random Variables

1 code implementation19 May 2017 Luca Ambrogioni, Umut Güçlü, Marcel A. J. van Gerven, Eric Maris

In the Bayesian filtering example, we show that the method can be used to filter complex nonlinear and non-Gaussian signals defined on manifolds.

Modeling the dynamics of human brain activity with recurrent neural networks

no code implementations9 Jun 2016 Umut Güçlü, Marcel A. J. van Gerven

Encoding models are used for predicting brain activity in response to sensory stimuli with the objective of elucidating how sensory information is represented in the brain.

Brains on Beats

1 code implementation NeurIPS 2016 Umut Güçlü, Jordy Thielen, Michael Hanke, Marcel A. J. van Gerven

We developed task-optimized deep neural networks (DNNs) that achieved state-of-the-art performance in different evaluation scenarios for automatic music tagging.

Dynamic Decomposition of Spatiotemporal Neural Signals

no code implementations9 May 2016 Luca Ambrogioni, Marcel A. J. van Gerven, Eric Maris

Neural signals are characterized by rich temporal and spatiotemporal dynamics that reflect the organization of cortical networks.

no code implementations17 Apr 2016 Arno Solin, Pasi Jylänki, Jaakko Kauramäki, Tom Heskes, Marcel A. J. van Gerven, Simo Särkkä

We apply the method to both simulated and empirical data, and demonstrate the efficiency and generality of our Bayesian source reconstruction approach which subsumes various classical approaches in the literature.

Deep Neural Networks Reveal a Gradient in the Complexity of Neural Representations across the Brain's Ventral Visual Pathway

no code implementations24 Nov 2014 Umut Güçlü, Marcel A. J. van Gerven

Converging evidence suggests that the mammalian ventral visual pathway encodes increasingly complex stimulus features in downstream areas.
