*Title: *       Deep Learning in Cancer Drug Response Prediction

*Abstract:* Artificial intelligence and machine learning (ML) specifically
is having an increasingly significant impact on our lives. Since the early
wins in computer vision from deep learning (DL) in the 2010’s, deep neural
networks have increasingly been applied to hard problems that have defied
previous modeling efforts. This is particularly true in chemistry and drug
development where there are dozens of efforts to replace the traditional
drug development computational pipelines with machine learning based
alternatives. In cancer drug development and predictive oncology there are
several cases where DL is beginning to show significant successes. In our
work we are applying deep learning to the problem of predicting tumor drug
response for both single drugs and drug combinations. We have developed
drug response models for cell lines, patient derived xenograft (PDX) models
and organdies that are used in preclinical drug development. Due to the
limited scale of available PDX data we have focused on transfer learning
approaches to generalize response prediction across biological model types.
We incorporate uncertainty quantification into our models to enable us to
determine the confidence interval of predictions. Our current approaches
leverage work on attention, weight sharing between closely related runs for
accelerated training and active learning for prioritization of experiments.
Our goal is a broad set of models that can be used to screen drugs during
early stage drug development as well as predicting tumor response for
pre-clinical study design. Results to date include response classifications
that achieve >92% balanced classification accuracy on a pan-cancer
collection of tumor models and broad collection of drugs. Our work is part
of a joint program of investment from the NCI and DOE and is supported in
part by the US Exascale Computing Project via the CANDLE project.

*Biography: *Professor Rick Stevens is internationally known for work in
high-performance computing, collaboration and visualization technology, and
for building computational tools and web infrastructures to support
large-scale genome and metagenome analysis for basic science and infectious
disease research. A current focus is the national initiatives for Exascale
computing and Artificial Intelligence (AI). He is the Associate Laboratory
Director at Argonne National Laboratory, and a Professor of Computer
Science at the University of Chicago. In addition, he is the principle
investigator of the NIH-NIAID funded PATRIC Bioinformatics Resource Center,
the Exascale Computing Project (ECP) Exascale Deep Learning and Simulation
Enabled Precision Medicine for Cancer project, and the predictive models
pilot of the DOE-NCI funded Joint Design of Advanced Computing Solutions
for Cancer (JDACS4C) project. Over the past twenty years, he and his
colleagues have developed the SEED, RAST, MG-RAST, and ModelSEED genome
analysis and bacterial modeling servers that have been used by tens of
thousands of users to annotate and analyze more than 250,000 microbial
genomes and metagenomic samples.
