Years ago, we build systems to predict delays on the German rail network. Paper here: https://www.sciencedirect.com/science/article/pii/S0968090X1... The complexity of operations i…

Isolating tech goes earlier than that. I know all my neighbours in my block who walk, cycle, or take the bus. Repeated interactions. The ones who take the elevator to the basement …

Interesting work. For a slightly different take using a similar intuition, see our paper [at ACL 2024]( https://arxiv.org/abs/2402.14860 ) on ranking LLMs which may be of interest.…

Pointers to said tools would be beneficial. Robust optimization is somewhat different from what the author states.

The ISO link[1] says this standard has been withdrawn however. [1] https://www.iso.org/obp/ui/#iso:std:iso:3103:ed-1:v1:en

Washington D.C. is a great example of this. While looking at residential location choice, around 10 years ago, you could discern a boundary (Georgia Ave in those days). Netflix use…

Always jarring to hear the claim > Technology is fundamentally neutral It is in the same way guns are fundamentally neutral. You can't view it without context. Include that and it …

Yes, Corbusier's vision of cities was tied to speed, and by consequence, to cars. But Chandigarh today has fantastic segregated bike infrastructure! No other Indian city comes clos…

Many causes have been put forward for this. However, I'm not sure the all safety aspects here have been well understood. Here in Dublin, Ireland the few weeks immediately after the…

One way to tell if a Machine Learning model is any good is to see how it does on unseen/new patients. Of course, we don't wait to try it on real patients, so typically you'd partit…

From the full paper[1]: > All models were trained on 70% of the data and tested on the remaining 30% of the data. Note that each month record for each participant was considered an…

I have not stated "all screening is bad". Broad-based population screenings as the parent comment suggests, in my opinion, are. I'm yet to see any clinically-valid distinguishing a…

Health policy is fraught with counter-intuitive phenomenon - and screening is one of them. Seems like it should help, but in practice leads to over-diagnosis. For example - Cancer …

One place this is abundantly clear is in the humanitarian sector, which I peeked into for a couple of years for a project. For all the talk about participatory processes, the entir…

Is there an accepted threshold for tropospheric NO2 concentrations above which it is considered harmful?

Inequity, education, sustainability, public policy, governance - few examples where techno-solutionism isn't the right approach.

Here is a revised link [1] to the full report. Table 1, on Page 10 shows a summary. [1] https://dms.ntsb.gov/pubdms/search/document.cfm?docID=477717...

I'd suggest reading the NTSB report on the pedestrian killed by Uber's "self-driving" vehicle [0]. The vehicle misclassified Elaine Herzberg so many times in the seconds leading up…

I think you've missed the point, going by your second paragraph. How capacity is provisioned from A to B influences how people choose to move and, over the long term, build homes/w…

Fully agree on the economic merits of English here. I think the point is more than methodological though. It is one of equity and access. Broad swaths of society don't have the sam…

This is absolutely spot on. A good deal of resources in some large organizations are wasted on vanity projects initiated by mid-management specifically for such value-capture.

Developed and developing are also terms that are arbitrary. Human Development Indices of some countries that are considered developing today exceed those of developed countries whe…

Governments do fall under the purview of GDPR. Do you have a source that states otherwise?

Really wonderful interview. One point that doesn't come up os that serious operational inefficiencies and "friction" exist in how current fixed route services are delivered in most…
