DrugAI-Gen.py (LSTM model)

Generator script for creating drug like molecule using LSTM model. Read more from here http://gananath.github.io/drugai-gen.html

DrugAI-GAN.py (GAN model)

This is my own experiments with Generative Adverserial Network (GAN) for drug like molecule generation. Teaching GAN in discrete dataset is hard and also I learned to code GAN from internet so would not gurantee any acurracy of the results or the code.

DrugAI-WGAN.py (WassersteinGAN model)

A Wasserstein GAN model with CNN; this model currently trains the fastest and probably gives the best result.

# Samples Generated 
['CC1=C(C(C(=O)O)(=CC=N2[S]CCCCCC(C(Cl)C1C4)[+])C2=C4=O|||||||||||||||||||||||||||' 'CC1=C(C(C(=O)OO(=CC=N2[N]CCCCCC(C(Cl)C1C3)[+])C2=CC=O)||||||||||||||||||||||||||' 'CC1=C(C(C(=O)O)(=CC=N2[N]CCC=CC(C(CO)C1C3)[+])C2=CC=O)||||||||||||||||||||||||||']

Recently I came across GAN's which uses condition like cGAN,acGAN etc. which uses a noise+class as input whereas I am using only class.

Another Dataset for Generation

Because I seen a increase in interest for DrugAI-Gen.py; for programmers I have added another dataset sms.tsv. It contains SMS spams. Try to use it for generating Spam's and Ham's.
