How does the primate brain combine generative and discriminative computations in vision?

no code implementations11 Jan 2024 Benjamin Peters, James J. DiCarlo, Todd Gureckis, Ralf Haefner, Leyla Isik, Joshua Tenenbaum, Talia Konkle, Thomas Naselaris, Kimberly Stachenfeld, Zenna Tavares, Doris Tsao, Ilker Yildirim, Nikolaus Kriegeskorte

The alternative conception is that of vision as an inference process in Helmholtz's sense, where the sensory evidence is evaluated in the context of a generative model of the causal processes giving rise to it.

Beyond linear regression: mapping models in cognitive neuroscience should align with research goals

no code implementations23 Aug 2022 Anna A. Ivanova, Martin Schrimpf, Stefano Anzellotti, Noga Zaslavsky, Evelina Fedorenko, Leyla Isik

Moreover, we argue that, instead of categorically treating the mapping models as linear or nonlinear, we should instead aim to estimate the complexity of these models.


Disentangled Face Representations in Deep Generative Models and the Human Brain

no code implementations NeurIPS Workshop SVRHM 2020 Paul Soulos, Leyla Isik

We further find that the latent dimensions in these models map onto non-overlapping regions in fMRI data, allowing us to "disentangle" different features such as 3D rotation, skin tone, and facial expression in the human brain.

Computational role of eccentricity dependent cortical magnification

no code implementations6 Jun 2014 Tomaso Poggio, Jim Mutch, Leyla Isik

From the slope of the inverse of the magnification factor, M-theory predicts a cortical "fovea" in V1 in the order of $40$ by $40$ basic units at each receptive field size -- corresponding to a foveola of size around $26$ minutes of arc at the highest resolution, $\approx 6$ degrees at the lowest resolution.
