Multitask Machine Learning for Classifying Highly and Weakly Potent Kinase Inhibitors

Abstract: Compound activity prediction is a major application of machine learning (ML) in pharmaceutical research. Conventional single-task (ST) learning aims to predict active compounds for a given target. In addition, multitask (MT) learning attempts to simultaneously predict active compounds for multiple targets. The underlying rationale of MT learning is to guide and further improve modeling by exploring and exploiting related prediction tasks. For MT learning, deep neural networks (DNNs) are often used, establishin… Show more

“…Rather than searching for similar molecules, machine learning models are trained to predict the activities of molecules based on their fingerprints. [8][9][10][11] This bypasses the need for similarity search but these approaches still rely, at its core, on precalculated fingerprints. A new class of ML algorithms, called Graph Neural Networks (GNN) are thought to overcome the calculation of fingerprints.…”

“…As a methodologically distinct application, MT-DNNs were trained for predicting highly and weakly potent inhibitors of different kinases and predictions were interpreted. The feasibility of such predictions was demonstrated previously [41]. The architectures of MT-DNN models contained multiple output neurons, each of which represented a different prediction task (target).…”

“…Clustering-based validation strategies have been used to avoid the compound series bias, making sure that there are no similar molecules both in training, validation and test sets. 18,26,27 We followed the implementation of our previous study on cross-validation strategies in PCM, 8 where K-means clustering with k = 100 was applied to the fingerprint description of the compounds. Data was divided in training, validation and test sets with a proportion of 80/10/10%.…”
