Description

dear professer:

I have been paying much attention on the dimension reduction technique, and recently, I try the architecure of parametric_umap with autencoding based on the Tf2.3 library. I want to the monitor the model accracy in the training process. How can i introduce the R^2 into the architecture of parametric_umap.

Looking forward to your reply.Thanks a lot.

Research direction

Start by reading the parametric_umap architecture and its TensorFlow 2.3 training path; the issue does not name a file, test, or entry point. Clarify whether R² should be added as a training metric and define the expected monitoring behavior before implementation.
