I building a deep learning model to detect what drug user use. I have many symptoms and duration of each drug. I create X and y data but, for example, LSD have an effect duration of 180 - 720 minutes. I really need make 540 arrays? I really want a help.

My LSD array:

[28, 180],
[28, 720],
[29, 180],
[29, 720],
[30, 180],
[30, 720],
[31, 180],
[31, 720],
[32, 180],
[32, 720],
[33, 180],
[33, 720],
[34, 180],
[34, 720],
[35, 180],
[35, 720],
[36, 180],
[36, 720],
[37, 180],
[37, 720],
[1, 180],
[1, 720],
[38, 180],
[38, 720],
[12, 180],
[12, 720],
[9, 180],
[9, 720],
[24, 180],
[24, 720],
[17, 180],
[17, 720],
[7, 180],
[7, 720],
[4, 180],
[4, 720],

In first position I have differents symptoms and in second position duration. I just duplicated each symptoms and set min duration and max duration. But this return to me a perfection model. I know, I need add all minutes to each symptoms, but how I make this using python?

List of symptoms

Sorry for my bad english :( Thanks

  • If you are actually using a deep learning model, with the amount of training data you have provided, it will very easily overfit. Simpler algorithms would be better for this like the decision tree you are using in your python code. – Aiden Grossman Sep 26 '17 at 00:25
  • This sounds like regression problem to me. – SmallChess Sep 26 '17 at 04:59

I have many symptoms and duration of each drug. I create X and y data but, for example, LSD have an effect duration of 180 - 720 minutes. I really need make 540 arrays?

You can (in this particular case, it's fairly easy to generate ~800 rows in CSV once), but you don't have to: you an apply data augmentation on the fly. This will add some randomness in your training, but it usually helps generalization.

By the way, it seems you aren't actually using deep learning, but rather DecisionTreeClassifier, which is a bit different.
