Representation Learning in Drug Discovery and Biological Systems
Challenges in Molecular Representation Learning
Representation learning is crucial for drug discovery and understanding biological systems. However, existing techniques often encode only a molecule’s chemical identification, leading to limitations in capturing the complex interplay between a molecule’s structure and its biological characteristics.
Addressing Batch Effects in High-Throughput Drug Screening
High-throughput drug screening faces challenges in handling batch effects, which can impact the interpretation of results. InfoCORE, an information maximization strategy, has been developed to effectively manage batch effects and enhance the quality of molecular representations derived from screening data.
Benefits of InfoCORE
Extensive tests have demonstrated that InfoCORE outperforms other algorithms in tasks related to molecular analysis and drug discovery. It effectively reduces the influence of batch effects, leading to improved performance in tasks such as molecule-phenotype retrieval and chemical property prediction.
Practical Applications and Versatility of InfoCORE
InfoCORE’s flexibility makes it a powerful tool for addressing various challenges related to data distribution and fairness, in addition to removing batch effects in drug screening. It can handle shifts in data distribution and data fairness problems, making it a valuable asset in diverse scenarios beyond drug development.
Key Contributions of InfoCORE
- Integrating chemical structures with high-content drug screens
- Maximizing the variational lower bound on the conditional mutual information of the representation given the batch identifier
- Outperforming baseline models in real-world studies for molecular property prediction and molecule-phenotype retrieval tasks
- Extending its effectiveness to removing sensitive information for representation fairness, with wider potential uses beyond drug development
