Can the Negative Weights be Input?

[BoanSy]

Dear authors,

can we input the negative weights into our original and target data simultaneously in thundergbm?

With best respect,

BoanSy, negative target values are totally fine. Negative feature values are also acceptable.

Thanks for your reply, but I'd like to ask how can we input them?
Like clf.fit(original, target, sample_weight=weights)?
