It’s the task of looking for mutations to the spike protein with both high grammaticality and high semantic change.
In Science, the authors write, “We identified escape mutations as those that preserve viral infectivity but cause a virus to look different to the immune system, akin to word changes that preserve a sentence’s grammaticality but change its meaning.”
