đź“Ż New blog post: "
Wavelength selection with a genetic algorithm"

If you're interested in , especially NIR or Raman, or , a suitable selection of wavelength bands is often needed to produce a good statistical model.

Genetic algorithms are optimisation procedures loosely inspired by the mechanism of evolution by natural selection.

In this point, I'm working through an example of variable selection with a genetic algorithm for regression.

A rather dramatic false-color look at Saturn, centered around the latitude of 55° North. Showing a corner-to-corner range of about 20,000 kilometers (12,500 miles), this uses near-infrared images taken by NASA's Cassini orbiter on July 20 2016.

Pillars of Creation

Thousands and thousands of stars have formed in this region. This is made plain when examining Webb’s recent (NIRCam) . In MIRI’s view, the majority of the stars appear missing. Why? Many newly formed stars are no longer surrounded by enough dust to be detected in mid-infrared light. Instead, observes young stars that have not yet cast off their dusty “cloaks.”
