IIUC, the layer is a classification head? Are there special operations inside the layer?

@aflah02 Thanks for reporting this feature request! I would like to understand this better, so you are proposing to add one preprocessing layer that constructs the BIO representations, which can...

Thanks! How would the BIO get used in the downstream model? Is it the prediction target? Also curious - is BIO always at character level?

Thanks! I think we want this tool, one more question - what does a dataset for NER tasks look like? Does it always come with sentence and spans, but missing...

Thanks for the detailed explanation! Could you write a colab to showcase how this layer would be used in an e2e flow? Since this is not a planned feature by...

@aflah02 For this tagging layer, I think we can assume that we have spans at token levels. Even if the dataset comes with span on original sentence level, the tokenizer...

Yes, the goal is to know which token is the start token and which one is the end token.

Once you pushed the new version, we may want to test on TPU as well. I will add some tests.

@aflah02 Thanks for the PR! I took a brief look and I am not sure if this works. Last time I checked the example code is working at string space,...
