How to train your VAE #7

Open xuzhang5788 opened 6 years ago

xuzhang5788 commented 6 years ago

If I have a new dataset, how can I use your code to train? It will be great if you could provide a procedure. Do you have any documentations on this code? Many thanks.

Hi,

I'll write up a more thorough procedure and fix some documentation later, but to answer your question quickly:

  1. Have your data prepared as a csv file. One of these columns should contain SMILES, the other should contain the properties you want to predict. This will be read later by mol_utils.load_smiles_and_data_df
  2. Create a json containing the characters found in the SMILES strings of this file. mol_utils.make_charset can help you do that.
  3. Copy the exp.json from models>zinc>exp.json, and change the data_file, char_file fields to match your experiment.
  4. Run chem.train_vae from the directory containing the exp.json.

Let me know if you have more questions.

Hi @jnwei I wonder is it possible to first feed a large dataset such as ZINC without the properties and then feed a much small one with the property such as the bioacitivity to a target. So that I can generate compounds with the bioactivity?

update

It seems that the issue has been created in #5, however no one replies.

Did you get to solve this?
