- Education: Most astronomers are not trained in code development resulting in maybe good but fragile code. Similarly, most computer scientists don't have the astronomy background or connections.
- Funding: Grants for methodology improvement are scarce. I wonder if these things can be funded from the computer science side of things in collaborations.
- Quality: Astro-informatics lacks support of state-of-the-art methodology as it stands.
I was much more interested in the final section about potential themes in research:
- Nonlinear dimensionality reduction.
- Deep learning.
I find the last theme incredibly broad and am unclear exactly how they mean it. It seems they're most interested in hierarchical representations of data. I would also claim that anomaly detection/clustering is important for reducing the volume of data.
