Can machine learning enable 100-plex cryo-EM structure determination? (Ellen Zhong, Ep #5) (links in reply) this is a podcast filmed with Ellen Zhong, a computer science professor at Princeton, and one of the giants (if not outright creators) of the field of deep-learning applied to cryo-EM particle images i... cannot emphasize how lopsided the ratio of (how important this field is) to (how interesting outside observers consider it) is. it's an area of research that i barely understood until last year. but now that i do grasp it, i increasingly believe that Ellen's work (especially in scaling up cryo-EM) will almost certainly end up being a weight-bearing pillar in the future of bio-ML here, we talk about the possibility of running cryo-EM at extremely high scales, what she did during her recent sabbatical at Generate:Biomedicines, her recent interest in areas beyond cryo-EM (cryo-ET and NMR specifically), and more (and thank you to Rush for sponsoring this! check out their preclinical computational tools at Timestamps: [00:00:00] Introduction [00:02:43] What does it mean to apply ML to cryo-EM?
