How to binning/tokenizing amplitude of stationary timeseries?

Question

I want to feed the amplitude of stationary timeseries into transformer.

I'm planning to tokenize/bin the amplitude into discrete value.

So, the transformer learn from unique integer token instead of continous value.

Specifically, it's an Electrocardiogram signal.

How do I do it?

Answer 1

This is straightforward of min-max scaling (normalization).

Except, the data is represented with unsigned integer after normalization. E.g. uint8 dtype can hold 2^8 or 256 vocabulary size.
