How to specify categorical columns

[Zheng Xiong]

Hi, thanks for providing such a useful toolkit. I want to ask that when we use Optimizer.optimise(space, data), how should we setup the input data so that mlbox could know which columns are categorical features that need to apply the encoding strategy? Thanks.

Hello @MasterXiong ! You don't need to specify which columns are categorical features (neither dates nor lists nor whatever...), MLBox will detect automatically :)
