The phones we hold can translate from one language to another. Yet, the engineers who programmed them typically do not know how this translation happens. This is because machine learning specifies a target macroscopic behavior, and a set of microscopic rules that enable networks to obtain them.
In a sense, this is similar to saying that we (roughly) understand the laws of evolution, but don’t understand the biology of a specific organism.
I focus on recurrent neural networks, and develop tools to “open the black box” and understand the dynamics these networks arrive to via learning.
