Region Layer Commitment

BaseModel layers have to be committed to cortical regions. For BaseModels that are automatically translated into BrainModels this is done on separate public data. The same layers are thus used when recording from the same cortical region, e.g. always the same layer for V1 instead of different layers per benchmark.
By default, committing layers to regions is done with a layer selection on separate public data: each model is tested on its alignment to brain data from each region (V1, V2, V4, IT) and the best layer is committed to that region. At the end of this step, the model thus has a fixed, unchangeable layer commitment for each region.

Visual Angle

Models have to declare their field-of-view so that stimuli can be displayed like they were displayed to experimental subjects. For instance, if experimental stimuli were shown at 4 degrees and a model's field-of-view is larger than that, then the stimuli are padded such that the core stimulus will make up 4 degrees in the model's field-of-view. Here's an example for a model declaring 8 visual degrees as its input.

Base image, presented at 8 degrees:

visual degrees 8 to 8

If image is presented at 4 degrees, model sees:

visual degrees 8 to 4

If image is presented at 12 degrees, model sees:

visual degrees 8 to 12
