How to classify so similar samples? : I'm trying to do a binary classification task on a set of sentences which are so similar to each other. My problem is I'm not sure how to deal with this problem with such similarity between samples. Here are some of my questions:

(1). Which classification technique will be more suitable in this case? 

(2). Will feature selection help in this case?

(3). Could sequence classification based on recurrent neural network (LSTM) be a potential approach to follow?

Thanks,
