A few of the ideas, topics, and commonplaces that have been gaining steam on arXiv during the last few months (yes, I do a lot of filtering to keep away most of the genAI stuff; explainer).
1. ICCV 2025: Papers from the 2025 International Conference on Computer Vision. All in all, a good peek at the state of the art.
Some recent articles:

- The 1st International Workshop on Disentangled Representation Learning for Controllable Generation (DRL4Real): Methods and Results
- VQualA 2025 Challenge on Engagement Prediction for Short Videos: Methods and Results
- 2COOOL: 2nd Workshop on the Challenge Of Out-Of-Label Hazards in Autonomous Driving
2. Fermion sign problem: Popular coverage of quantum physics often skip over how fiendishly complicated are the actual calculations. In many cases — you could say in most realistically complex cases — we know the equations but simply can't calculate the concrete numbers due to its sheer complexity or extremely problematic technical difficulties; the numerical sign problem (of which the fermion sign problem is a particularly important case) is one of those. This complexity is part of why everybody is so eager to have quantum computers (forget running ChatGPT, we need those for things like material design and molecular biology) or AI that could give good practical estimates, but it's also why you should be very skeptical of AI that e.g. predicts how a drug will work inside a cell; the idea that you can learn how to do that purely from crunching our meager data sets is at best implausible.
