deep learning will play on causal discovery is, at best, uncer - |
tain because deep learning models focus mostly on fitting |
and are largely overparameterized, which is (apparently) |
against causal, sparse, reasoning. Only very recently have |
we witnessed efforts toward either incorporating or under - |
standing deep models causally: the authors in [ 89] imple - |
mented a metalearning objective that maximizes the speed of domain transfer, which, under certain assumptions, can |
be seen as a way to localize changes in causal mechanisms. |
In [90], the authors learned individual-level causal effects |
from observational data that can efficiently handle con - |
founding (hidden) factors. Both methods are, in principle, |
well suited to the problems in remote sensing and geosci - |
ence data sets, which exhibit spatiotemporal relationships |
to be exploited but have not (thus far) been considered. |
Yet we will have to face a more important challenge: |
cognitive barriers. Domain knowledge is elusive and dif - |
ficult to encode, interaction between computer scientists |
and physicists is still a barrier, and education in synergistic |
concepts still needs to become a reality in coming years. |
Causal inference is believed to be the best approach to de - |
velop Earth sciences, but this will be possible with a strong |
and continuous interaction between domain knowledge |
experts and computer scientists. |
CONCLUSIONS |
This article described the six ideas and six directions |
in which geosciences, Earth observation, and AI can |
achieve a lot if synergistically combined. With this ar - |
ticle, we have provided our appreciation for research av - |
enues that are new, refreshing, and exciting for scientists |
willing to evolve at the interface between AI and the geo - |
sciences. We hope that they will spark curiosity and that |
the community, especially the younger generations, will |
embrace them. |
