I want to predict lead time in supply chain, where dependent features are material, vendor, price, quantity,etc….., this can be done by using random forest regression model, but random forest regression model does not support incremental learning, so I am looking for other model that supports incremental learning as well as the model which supports GPU.

I have tried random forest regression model and support vector machines, in random forest regression model incremental learning was problem and in SVM handling categorical data was problem.
