Causal Diagrams

Like Sankey diagrams, causal diagrams are a useful tool to assess and communicate complicated systems and their intrarelationships: It’s possible to use these for analysis and prescription: Here is the (promised) presentation on reenforcing loops: So how can these techniques … Continue reading

Life cycle analysis of emissions from various forms of energy converted to electricity

There was a recent discussion regarding the life cycle analysis of various forms of energy, principally to be converted to electricity. Given that everything I know about sustainability and life cycle analysis suggests is it is a very complicated business, … Continue reading

Google’s DeepMind consistently beats Fan Hui, the European GO grandmaster

This is pretty amazing news. DeepMind’s program AlphaGo beat Fan Hui, the European Go champion, five times out of five in tournament conditions, the firm reveals in research published in Nature on 27 January. It also defeated its silicon-based rivals, … Continue reading

Professor Marvin Minsky dies at 88: What a noble mind is here o’erthrown

As a prospective and actual graduate student in MIT’s Artificial Intelligence Laboratory during the years 1974-1976, it is difficult to convey the draw and the incisiveness of Minsky’s mind. As an undergraduate in Physics with a very keen interest in … Continue reading

Generating supports for classification rules in black box regression models

Inspired by the extensive and excellent work in approximate Bayesian computation (see also), especially that done by Professors Christian Robert and colleagues (see also), and Professor Simon Wood (see also), it occurred to me that the complaints regarding lack of … Continue reading

On friction and the duplicity

(Hat tip to Peter Sinclair at Climate Denial Crock of the Week.) Has Senator Cruz called Dr Carl Mears (video) of Remote Sensing Systems, the maker and interpreter of the sensor Senator Cruz used for his Spencer-Christy-Curry carnival? No. Of … Continue reading

“Causal feedbacks in climate change”

Today I was reviewing and re-reading the nonlinear time series technical literature I have, seeking ideas on how to go about using the statistical ensemble learning technique called “boosting” with them. (See the very nice book, R. E. Schapire, Y. … Continue reading

Social implications of our silly experiment with Earth

Climate is changing. Climate change is threatening to human elites. Climate solutions are “fetishizing the billionaire class”. And on the risks and damage from neoliberalism. Exponential growth, meaning keeping the permitting of new homes in the suburbs, is lethal. We’re … Continue reading

After the Decade of Dithering, the Deadly Twenties

In a recent post, after reviewing the extreme Arctic warming event of late 2015, Professor John Baez quotes an earlier interview with Dr Gregory Benford, who is arguing for a geoengineering effort to restore the frozen Arctic. I do not … Continue reading

Hunt and Anderson discuss climate change

50% of the emissions come from the richest 1% of people on the planet. Actually, I disagree with them a bit … I suspect Western societies are much more fragile than Hunt & Anderson and most people think, in terms … Continue reading
