What did you do last week?
Writing a summary of [in-house TTTC
Examples of Broad Listening Applications within Cybozu
Remaining work on the public opinion map
I was wondering if it would be possible to create a detailed map for the ones with the most people.
At first I was thinking of keeping PCA and increasing the k of k-means, but then I decided to try [UMAP the opinion vectors
Past Case Studies
Opinion cluster analysis of 110,000 people did an analysis fixing K=5, not very interesting
Polis-like visualization of the 2022 House of Councillors election would be two in Polis, but it's actually one lump, which I thought would be a limitation of PCA.
As a comparative ease of use, I UMAPed the data used in the "Polis-like Visualization of the 2022 House of Councillors Election".
UMAP visibility for the 2022 Upper House election
Overwhelmingly and clearly divided.
I did the same thing with 110,000 data and it wasn't very interesting: 110,000 UMAP.
This, too, well, I think the structure is such that it cannot be reduced to two dimensions even with UAMP.

What to do this week
I've done a lot of broad listening from opinion vectors, so I want to do broad listening from text.
However, now that we have the final data for the poll map, I'd like to analyze that as well.
It's Wednesday now, so there's not much of the week left.
