Increasing latent dimensionality does not fully correct overconfidence. Error/accuracy (left) and coverage at 95% credibility level (right) for GLLVMs with different latent dimensionalities. GLM and GLLVM results reflect the full population of neurons for each experimental setting. For comparison, results with reduced populations of 20 neurons are included here for the GLM and one-dimensional GLLVM, selected using a greedy optimization to create the “best” and “worst” error/accuracy. Error bars denote 95% confidence intervals. Dashed lines denote nominated coverage of 95%. Light and dark colors for the best/worst greedy decoders denote results from the GLM and 1D GLLVM, respectively.
