Extracting a black hole image from "sparse telescope matrix"

Katie Bouman is a human face of the team that produced a black hole image that hit the news today:


2 years ago Katie delivered a TED talk about that image extraction efforts:

It is an interesting presentation, but I do NOT understand Katie's explanation about how they were going to minimize the bias [to "see" already predicted black hole visualization] while creatively interpreting inputs from sparsely placed telescopes around the earth.

Do you understand Katie's explanation?
