There are 2 main things in tsfresh:\r\n1. Feature extraction (I saw you have a rather long list of features you create)\r\n2. Feature filtering\r\n \r\nI have some general questions:\r\n1. What is unique about the feature filtering ? for example, let's say I want to use the features for classification. Can't I just take all the features to an information.gain software (like FSelector in R), it will tell me how good/bad each feature is, based on information gain, and by this way to use the feature ?\r\n2. You have a long list of features, from your experience, how much is left after feature filtering ?  I know it is  a very general question, and it is very time series specific, but I wonder, from your experience, the typical filtering.\r\n3. What is the \"smart thing\" about the tsfresh solution ? Is it new features, new filtering method, combo, please epxlain ?       \r\n4. Any other insights you can provide on the algorithm Vs. other feature extraction and feature importance algorithms (RF,information.gain, …)\r\n \r\n \r\n"},"comment":{"url":"https://api.github.com/repos/blue-yonder/tsfresh/issues/comments/259206626","html_url":"https://github.com/blue-yonder/tsfresh/issues/47#issuecomment-259206626","issue_url":"https://api.github.com/repos/blue-yonder/tsfresh/issues/47","id":259206626,"user":{"login":"MaxBenChrist","id":13162426,"avatar_url":"https://avatars.githubusercontent.com/u/13162426?v=3","gravatar_id":"","url":"https://api.github.com/users/MaxBenChrist","html_url":"https://github.com/MaxBenChrist","followers_url":"https://api.github.com/users/MaxBenChrist/followers","following_url":"https://api.github.com/users/MaxBenChrist/following{/other_user}","gists_url":"https://api.github.com/users/MaxBenChrist/gists{/gist_id}","starred_url":"https://api.github.com/users/MaxBenChrist/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/MaxBenChrist/subscriptions","organizations_url":"https://api.github.com/users/MaxBenChrist/orgs","repos_url":"https://api.github.com/users/MaxBenChrist/repos","events_url":"https://api.github.com/users/MaxBenChrist/events{/privacy}","received_events_url":"https://api.github.com/users/MaxBenChrist/received_events","type":"User","site_admin":false},"created_at":"2016-11-08T17:44:22Z","updated_at":"2016-11-08T17:44:22Z","body":"Does this answers your questions?"}}
