I've previously written about molecular generators based on long short-term memory recurrent neural networks (LSTM-RNNs). The networks learn rules about how SMILES strings of molecules are formatted and are then able to create novel SMILES following the same rules by iterating through the characters. The results are "creative" computers that can ...

The SMILES enumeration code at GitHub has been revamped and revised into an object for easier use. It can work in conjunction with a SMILES iterator object that give on-the-fly enumeration and vectorization for training of SMILES based Recurrent Neural Network (RNN) models of molecules for ...

The film Inception with Leonardo Di Caprio is about dreams in dreams, and gave rise to the meme "We need to go deeper". The title has also given name to the Inception networks used by Google in their Inception network. I recently stumbled across two interesting ...

In the last blogpost the battle tested principal components analysis (PCA) was used as a dimensionality reduction tool. This time we'll take a deeper look into chemical space by using a deep learning neural autoencoder, by testing some of the newer tools based on neural networks which has shown promising results. ...
