[D]Choosing right aws instance.

Recently I have started competing on Kaggle and thus dealing with datasets of size ~1GB.Most of the models that I run are CART(Classification and regression trees).I am running these models on my machine(MacBook Air,1.4 GHz Intel Core i5, 4 GB 1600 MHz DDR3, Intel HD Graphics 5000 1536 MB,120GB Flash storage).Typical hyperparameter tuning takes a long(very long) time to run.I am not doing anything related to deep learning. So I decided to shift my computation to AWS.But there are a plethora of instances to choose from.Anybody with sufficient experience using these can suggest what configuration should I go for?Which instance should I choose? Any question for further clarification about my use case is welcomed. submitted by /u/jassi1994 [link] [comments]
