If you have any doubt, with these connectivity graphs, use the image display instead. => Could you check that this fix looks good to you? I'm a bit confused with the way the colors are handled in this function. This one is a bug, I tried to fix it in this commit: Both topic coherence measures UCI and UMass are based on the sum i < j score. This measure can be seen as the sum of all edges on complete graph. In the last picture, we activated in the Graph Options the "Display region Max" option,Īnd now we got some blue links also visible. Both measure compute the sum Coherence i < j score ( w i, w j) of pairwise scores on the words w 1,, w n used to describe the topic, usually the top n words by frequency p ( w k). Right-click on the figure > Colormap > Disable "absolute values" We find that standard coherence scores that are often used for the evaluation of topic models perform poorly as an evaluation metric. Probably because the colormap is configured to display only absolute values. Yes, we should even disable this slider, as we do for the statistical results on the source maps. So you mean, that we should keep the slider bar always on the most left side (at the minimum score) of the slider to visualize all statistically meaningful connections? What could possibly help, as all three subjects were handled with similar method,īut only one displays the independent permutation t-test Fc graphs. Two subjects tell this same error when I try to display any of the statistical Perm-t test graph.Įrror in figure_connect>LoadConnectivityData (line 1158)Įrror in figure_connect>LoadFigurePlot (line 1613) Only one of these 3 subjects will open Fc graphs, Now all 3 subjects have each 3 statistical tests that I would like to display as graphs (Fc circle graph) To compare statistically each folder CohNxN Fc matrices B, C and D with folder A CohNxN Fc matrices. I calculated three independent permutation-t tests Continuing the discussion from Permutation test on connectivity:Īnd each subject has 1 folder (name "A) with about 40 Coherence NxN Fc matrices,Īnd 3 additional folders (Names "B", "C" and "D") with each of these folders having about 20 Coherence NxN Fc matrices.
