Reproducible Research with End-to-end Machine Inference Using Deep Learning and Bayesian Statistics

The conventional statistical inference based on hypothesis testing and p-value is fundamentally flawed. The general practice of data analysis involves too many post hoc decisions makings based on p-value, which unavoidably violates the... continue reading

Make computer-aided research more verifiable

A central problem with modern computer-aided research is that research based on long computations becomes difficult to verify. It is thus unclear how and why such should be trusted. The most widely discussed aspect of this problem is the... continue reading

Some reports of NGOs and anecdotal evidence suggest that child abuse materials (CAMs) share some characteristics extensively. They mostly take place indoor settings, victims' face or genitalia is visible and there are few visual clues about the... continue reading

Searching for Dyson spheres with Gaia

Assuming that Dyson spheres obscure optical/near-infrared light as grey absorbers, a partial Dyson sphere with high covering fraction (fcov > 0.5) could reveal itself as an anomalously subluminous star with a parallax-based distance smaller than... continue reading

The simple observation by Huygens that disproved Newton's rule for the extraordinary refraction of calcite

Huygens (1629–1695), in his Treatise on Light (1690), explained the double refraction of calcite on the correct hypothesis that the secondary waves for the... continue reading

Carbon concentrations in phytoliths and carbon sequestration in soil

In recent years there has been much work on the possibility that carbon could be sequestered in phytoliths and contribute to solving global warming.1,... continue reading
