Research Type Experimental Here, we show analytically and numerically that resource allocation scales nonlinearly in efficient coding models that maximize information transfer, when inputs arise from separate regions with different receptor densities. (...) We tested numerically how neurons in a visual bottleneck should be allocated to different input regions, reflecting the fact that the density of cone photoreceptors is not constant across the retina.

Pseudocode No The paper provides mathematical derivations and descriptions of the methods, but no structured pseudocode or algorithm blocks.
Open Source Code No The paper provides a link to a dataset used (http://salicon.net), but does not state that the code for their methodology is open-source or provide a link to it.
Open Datasets Yes We included 2,000 randomly sampled images from the SALICON image data set2 [13], converted the images to 8-bit grayscale, and then extracted luminance values along horizontal lines extending 160 pixels each. (...) 2The full data set can be downloaded from http://salicon.net.
Dataset Splits No The paper describes using a dataset but does not specify any training, validation, or test splits. It primarily focuses on analytical derivations and numerical simulations based on the properties of the dataset.
Hardware Specification No The paper does not provide any specific details about the hardware (e.g., GPU/CPU models, memory) used to conduct the numerical simulations or analysis.
Software Dependencies No The paper does not list any specific software dependencies with version numbers (e.g., programming languages, libraries, or specialized solvers).
Experiment Setup No The paper describes the mathematical derivations and steps for calculating eigenvalues from the data, but it does not specify experimental setup details such as hyperparameters, learning rates, batch sizes, or training schedules, which are typical for machine learning models.
