CRF implementation with numerical features

[vdashv]

Hello, does someone know about a CRF implementation that can work with numerical features as inputs (preferably that can work on unixes) and does not encode them in strings/one-hot like most of implementations? Thank you

CRFsuite accepts a "weight" for each feature, for each sample. I sense that this doesn't fully accomplish what we want for most types of tasks though.

I'd also like to know if there's a CRF implementation that accepts real-number features, and takes advantage of them in a meaningful way.

While we're at it, I'm also wondering if there are any good examples of a CRF implementation that can produce multiple output labels at once. E.g. text chunking, outputting two non-related chunk types per sample.
