Alberta’s Oil Sands: Hard Evidence, Missing Data, New Promises

P itched battles are a regular occurrence in northern Alberta, Canada, as development of the province's oil sands continues to expand. One ongoing battle—with another salvo launched in February 2011 with the leak of a European Commission report 1 —concerns how dirty oil sands are, relative to other fuels. Another concerns the influence of the oil sands industry in monitoring its own activity. 2...

Imposing Hard Constraints on Deep Networks: Promises and Limitations

Imposing constraints on the output of a Deep Neural Net is one way to improve the quality of its predictions while loosening the requirements for labeled training data. Such constraints are usually imposed as soft constraints by adding new terms to the loss function that is minimized during training. An alternative is to impose them as hard constraints, which has a number of theoretical benefit...

In the target article I argued that cognitive neuropsychologists have increasingly deviated from the original goals and methods of the subject. In this reply to the commentators, I argue that future progress using neuropsychological approaches to understanding behaviour is most likely to be made by the use of converging sources of evidence that are garnered by an interdisciplinary methodology. ...

Promises, promises.

It’s easy to think that there is no problem facing medicine that information technology can’t solve. Experience in the US gives little reason for optimism. Huge investments havemostly failed to solve old problems and have created new ones. US doctors report spending two hours on computer tasks for every hour with patients (doi:10.7326/M16-0961). Poor usability and limited interoperability of el...
