tCNNS
Twin convolutional neural network for drugs in SMILES format.
Model Architecture
tCNNS consists of two 1D convolutional neural network (CNN) branches for distilling the features for drugs and cell lines separately, each with three layers. After the two branches of the CNN, there is a fully connected network (FCN) with three hidden layers, which aims to do the regression analysis between the output of the two branches and the drug response values. tCNNS was one of the first models to apply CNNs to the problem of drug prediction.
Feature Representation
Cancer features:
Mutation: as binary
CNV: as binary
Drug features:
SMILES: converted into a 28 by 188 one-hot matrix where a value 1 at row i and column j means that the ith symbol appears at jth position in the SMILES string
