HDPを実装してみました・・・
HDP (hierarchical Dirichlet processes) をLDAに使った場合を,実装してみました.HDPのハイパーパラメータは固定したままで,サンプリングはまだ実装してません.バグとり、大変でした・・・。

某データセットで実験してます.このデータセットでは,トピック数が41に落ち着きました(データのクリーニングの失敗による、明らかにおかしな単語が集まったトピック1つを除く).各行が別々のトピックに対応していて,単語は頻度の高い順にソートしたトップ20です(stemming後なので,ちょっと変な英単語ですが).この結果を見る限りは,ちゃんと動いてくれているような・・・.まあ、引き続き、動作チェック、動作チェック、と。
