I have huge dataset in my single computer so that memory is insufficient.
I want to train incrementally with xgboost, but I found incremental training isn't like what I thought.
I thought:
Data_A incrementally -> train Data_B incrementally is equal to train (Data_A + Data_B)
Actually:
Data_A incrementally -> train Data_B incrementally isn't equal to train (Data_A + Data_B) .
And accuracy/mse still decrease a little.
I realize that training incrementally doesn't train like whole dataset, it treats newer dataset as new training set.
And then it stores previous and newer estimators(trees) in a same model.
Any ML model can reach to train incrementally but doesn't lose accuracy?

Have you tried to use a generator? It will stream your data instead of directly loading everything into your memory (see this great tutorial:stanford.edu/~shervine/blog/…).

When doing neural networks you should consider switching to TensorFlow/Keras. It is very easy and intuitive.
