Using Optical Aberrations to Distinguish Real Astronomical Transients

https://arxiv.org/static/browse/0.3.4/images/arxiv-logo-fb.png
The detection of fast astronomical transients in photographic plates from the Palomar sky surveys conducted in the 1950s, was subject to the criticism that such transients could be just the effect of otherwise unaccounted for plate artifacts. In this paper, we show that transient images exhibit the coma aberration pattern expected from off-axis point sources recorded through the telescope ...

The Effective Sample Size

https://alex.smola.org/posts/40-effective-sample-size/heavybirds.jpg
Years ago I wrote about correcting covariate shift by reweighting your data. Your features come from the wrong distribution \(q\), you care about a target \(p\), so you weight every observation by \(\beta_i = p(x_i)/q(x_i)\) and your estimates are unbiased again. I ended that post by admitting the weights “can be quite a bit off,” and waved at fixing it another day. Here is the more basic ...
