In the TFX Evaluator, on top of the metrics described in TFMA format,I would like to compute statistics relative to the performance of my model on my dataset. Naturally, I would also like a way to get access to these statistics: either through the output of the component, or by letting the component upload the statistics somewhere.

I guess that some amount of custom code would be needed (both for the computation and the return of the statistics), but I don't really know how much and what would be the best way to write it. Any ideas on the topic ?

Thanks

There are 2 methods that you can achieve this depending on how you see the placement of your functionality in the TFX flow.

  1. Writing a Custom TFX Components - which requires a lot of effort and you need to define quite a few things.
  2. Reusing Existing Components - instead of writing a component for TFX entirely from scratch, we can inherit an existing component and customize it by overwriting the executor functionality.

I would suggest the following blogs to begin with:
