Description:

acda 0.0.6

Overview
This repository stores drug synergy prediction codebase for Augmented Cancer Drug Atlas (ACDA) and the analysis jupyter notebooks which use the ACDA code. We augmented the drug synergy prediction modeling approach CDA described in Narayan et al. by applying a Random Forest Regression and optimization via cross-validation hyperparameter tuning. For ease of sharing and use we implemented it as a python package. See documentation at https://acda.readthedocs.io.
Installation and Dependencies
The main prerequisite o install the Python package is python >3.8 environment. To install run:
pip install acda

The dependencies are installed automatically with the command above. See setup.py for the very basic dependency list.
Methods Description
Drug Synergy prediction is a complex problem typically approached with Machine Learning techniques by using molecular and pharmacological data. A recently published method Cancer Drug Atlas, CDA (Narayan et al. 2020), for drug synergy prediction in cell line models uses drug target information, knowledge of genes mutated in each model, and models' monotherapy drug sensitivity. The approach builds a logistic regression model to predict a binary synergy outcome. Here, we improved the CDA drug synergy prediction modeling approach by applying a CART-based model instead of a linear regression.
The datails of ACDA methods and benchmarking results are described in the preprint.
