Architecting for success with Artificial Intelligence - Dr Steve Gustafson - CTO Noonum

#AutoML #MLOps #ArtificialIntelligence
Dr Steven Gustafson discusses what the difference is between success and failure of Artificial Intelligence projects in industry and presents a case study. He also introduces a framework for AutoML that he has invented and published.
Dr Steven Gustafson received his PhD in Computer Science and Artificial Intelligence, and shortly thereafter was awarded IEEE Intelligent System's "AI's 10 to Watch" for his work in algorithms that discover algorithms. For 10+ years at GE's corporate R&D center he was a leader in AI, successful technical lab manager, all while inventing and deploying state-of-the-art AI systems for almost every GE business, from GE Capita...
