Together, these findings demonstrate the computational benefits of high-dimensional sensory codes, and they suggest that current neural network models of visual cortex may be better understood in terms of the richness of their representations rather than the details of their training tasks.Ĭitation: Elmoznino E, Bonner MF (2024) High-performing neural network models of visual cortex benefit from high latent dimensionality. Our findings revealed striking benefits of networks with higher effective dimensionality, which were consistently better predictors of cortical activity patterns and were able to readily learn new categories of images outside of their training domains. We quantified the effective dimensionality of neural networks created using a diverse set of training paradigms and compared these networks with image-evoked codes in the visual cortex of both monkeys and humans. However, there are competing benefits of high-dimensional codes, which can capture rich perceptual information to better support an open-ended set of visual behaviors. In vision, it has been argued that there are crucial benefits of representing images using codes that are as simple and low-dimensional as possible, allowing representations to emphasize key semantic content and attenuate irrelevant perceptual details. The effective dimensionality of neural population codes in both brains and artificial neural networks can be far smaller than the number of neurons in the population. These findings suggest a general principle whereby high-dimensional geometry confers computational benefits to DNN models of visual cortex. Moreover, we found that high dimensionality was associated with better performance when learning new categories of stimuli, suggesting that higher dimensional representations are better suited to generalize beyond their training domains. Surprisingly, we found a strong trend in the opposite direction-neural networks with high-dimensional image subspaces tended to have better generalization performance when predicting cortical responses to held-out stimuli in both monkey electrophysiology and human fMRI data. A popular view holds that optimal DNNs compress their representations onto low-dimensional subspaces to achieve invariance and robustness, which suggests that better models of visual cortex should have lower dimensional geometries. Here we examined the geometry of DNN models of visual cortex by quantifying the latent dimensionality of their natural image representations.
