Title: Learning and Active Mechanics
Abstract: Physical learning is an emerging paradigm whereby materials acquire behaviors by exposure to examples. So far, it has been applied to static properties encoded in energy minima. In this talk, we extend it to dynamic functionalities, such as motion and shape change. Using a generalized Hopfield model, we delineate the key physical ingredients needed and illustrate them with LEGO toys as well as potential active matter platforms based on oil droplets with chemotactic signaling that learn life-like functionalities. Next, we turn to investigate how living organisms themselves exploit active mechanics to change their shape. Using machine learning, we infer an interpretable model of morphogenesis in Drosophila embryos that captures how tissue flow is regulated by protein dynamics and validate it with a mutant analysis. This data driven model taken together with experiments on human stem cells suggest that our machine-learned mechanism for early neuroectoderm morphogenesis is conserved across species.
