How Machine Learning is Helping us Get Smarter at Healthcare
ClearDATA’s Chief Technology Officer Matt Ferrari shares insights on:
•Machinelearninginthepubliccloud
•Industrysectorusecases
•Examplesofcloud-managedservicesformachine learningapplications
This whitepaper is designed for healthcare execs looking for a foundational understanding of what machine learning means to healthcare in the public cloud. These are the observations and opinions of ClearDATA’s CTO Matt Ferrari and does not imply endorsement of his comments from any of the three public clouds mentioned: Amazon Web Services, Google Cloud Platform and Microsoft Azure.

Oneofthemajorusecasesforthisapproachisresearchthatseekstounderstandhowgeneticdifferencesdeterminetheresponsesofindividualstoparticulardrugs.Toaccomplishthisgoal,dataonthephysicalcharacteristicsandmedicalhistoriesofindividualpatients,knownasphenotypes,arecomparedtotheirgeneticfeatures,knownasgenotypes,whicharederivedfromgenomicsequencing.
