Question About Hierarchical Tree Depth in .hier File

[kunalkathare]

Thank you for making this project open-source and for providing detailed documentation. I have a question regarding the hierarchical tree structure in the .hier file:

1. After fine-tuning the chunk and creating the hierarchical tree as a .hier file, I observed that the tree has a maximum depth of 1 (i.e., levels 0 and 1).

2. In your paper, you mentioned that the tree is formed and then merged back from the leaves to the top. Could this be the reason why I am only seeing a maximum depth of 1 in the resulting hierarchy?

I would greatly appreciate it if you could clarify this behavior or point me to where I might be going wrong.

Thank you for your time and for sharing this excellent work!

Best regards,
Kunal
