Jointly efficient encoding and decoding in neural populations

Fig 3

Qualitatively different optimal configurations.

In all simulations, N = 10 and . Top row: high-distortion, low-rate solution. Bottom row: low-distortion, high-rate solution. (A) Bell-shaped tuning curves of the encoder (probability of neuron i to emit a spike, as a function of x). (B) Comparison between the stimulus distribution, π(x) (green curve), and the generative distribution, p_ψ(x) = ∑_r p_ψ(x|r)p_ψ(r) (purple curve). (C) Numerical values of the ELBO, and the distortion and rate terms.
