Rustで生成AIと埋め込みモデルをぶん回して、PyO3でPython呼び出してHDBSCANでクラスタリング。結果用のHTMLをRustで書かせてJavaScript＋Plotly.jsとともに生成AIの成果物とクラスタリングの結果を埋め込み。思いの外きれいにまとまった。

HDBSCANの処理を組むにはPythonでやるのが楽だなーとなった

During last weeks I tried to do some hipertunning of the DBSCAN parameters (eps and min_samples). I'm not very happy with the results, so I'll try to investigate a bit more before jumping to HDBSCAN. @emily.space do you know any work related with this hipertuning in DBSCAN? Thanks in advance!

I do not want to make keyword clusters from 32,052 keywords. I do not want to have to learn what porter stemming is. I do not want to have to learn what HDBSCAN is. I do not want to touch an api key. I was an english major for a reason. please don't make me do computer.

Just to clarify; would you say that e.g. HDBSCAN is worthless, or just worthless in psych?

Today I am finishing reading several papers (some by @emily.space ) on methods of membership analysis in open clusters: DBSCAn, HDBSCAN, GMM... It is a complex problem, and it was the kind of problem I expected to encounter when I started my personal project to learn how to analyze astronomical data
