Maturation of number acuity in deep networks. (A) GLM fit for one Young (left panel) and one Mature (right panel) network, visualized as in41. Black lines indicate the model fit for all data (black circles). Red color shows data and model fits for the trials with extreme Size ratio, while green color shows data and model fit for trials with great Spacing ratio. Dashed lines indicate that Size or Spacing were congruent with numerosity, while dotted lines indicate incongruent trials. (B) Left panel: Differences in Numerosity, Size and Spacing coefficients, measured separately for the Young and Mature networks. Right panel: Differences in angles between the discrimination vector and the most relevant non-numerical features, measured separately for the Young and Mature networks. (C) Comparison between angle and coefficients changes in humans (data replotted from24) and deep networks. Note that angle differences for both humans and networks have been scaled by a factor of 10 for visualization purposes.
