Imputation of Sensory Properties Using Deep Learning: webinar

Oct 19, 2021

In this webinar, we demonstrate how Augmented Chemistry®, a unique deep learning method, can learn from higher throughput data together with limited panel data to provide high-quality imputations for sensory properties.
• Find novel active compounds with 3D virtual screening against known actives:
• Demonstrate the imputation of sparse physicochemical and sensory data
• Compare the results with conventional quantitative structure-activity relationship (QSAR) methods
• Present robust uncertainty estimates generated by the imputation model, highlighting the most accurate predictions to guide decision making
• Show that imputation more accurately predicts activity cliffs, where small changes in compound structure result in large changes in sensory properties.

Sensory properties are subjective measures assessed by panels of trained experts in an expensive and time-consuming process. We were joined by Dmitriy Chekmarev, Senior Research Investigator in computational sciences at IFF, to discuss the challenges of using this sparse and noisy sensory data in predictive models.
