We participated in the 1st EUOS/SLAS joint challenge on Kaggle, which was a three-way classification task based on the solubility of 100k small drug-like compounds. During our participation, we intensely used the platform OCHEM (On-line chemical database with modeling environment) to generate the best descriptor-based method throughout the competition. The final predictions were generated by a consensus model using the average over 28 single models.
