The machine learning algo zoo

May 16, 2022 Matt Hall Environmental and Earth Sciences

One of the wonderful, but also baffling, things about machine learning is that there are so many ways to do it. At some very high level, most of them do something like this (highlighting some jargon):The human settles on a task (“Predict lithology”) and finds a bunch of data relevant to that task (say, some...

Comparing regressors

May 9, 2022 Matt Hall Environmental and Earth Sciences

There are several really nice comparisons between various algorithms in the Scikit-Learn documentation. The most famous, and useful, one is probably the classifier comparison: A comparison of classification algorithms. Each row is a different dataset; each column (except the first) is a different classifier, each trying to separate the blue and red points. The accuracy...

In the Heart of the City: Natural History in Edmonton

As a long-time Edmontonian, I figured it would only be right to start this off by talking about the things for a naturalist to see in Alberta's capital city. Edmonton is surrounded by a variety of enticing places for nature lovers willing to take a drive out of town, but many folks might not know...

Take one, make one

May 2, 2022 Matt Hall Environmental and Earth Sciences

There’s a teaching method originating in medicine known as “see one, do one, teach one”. I like it because it underscores hands-on practice and knowledge sharing as essential steps in developing a craft — and it works. Today, I want to urge you to take a challenge, then make one for others.First, what’s the challenge?...

Lowering the drawbridge

April 27, 2022 Amanda Tracey Biology and Life Sciences, Communication, Education and Outreach, Environmental and Earth Sciences

Colour-banded bluebirds make frequent appearances in my dreams. A couple of nights ago, I sat bolt upright in bed at 5:30 am, sweaty and stressed from a dream of chasing a banded bluebird whose colour bands I never got quite close enough to decipher. This is one of the ways I know it’s spring: the...

Nature Journaling, Monday to Friday: Backyard Flowers

April 22, 2022 chloevanloon Biology and Life Sciences, Communication, Education and Outreach, Environmental and Earth Sciences

I had a mad craving for some nature journaling last week. So I took to our current “backyard” in the outskirts of Ramona in a small community called Fernbrook which is in the county of San Diego, California. Nature journaling is a super-duper way to connect with nature, at the landscape or macroscopic level. Journaling...

Contraintes en matière d’énergie

March 11, 2022 Harvey Mead Environmental and Earth Sciences, General Science, Policy and Politics

J’ai commencé la rédaction de cet article avant qu’il y ait des réflexions par les intervenants sur la réponse possible de l’Occident en termes des exportations de la Russie. Cela est maintenant à suivre, mais l’analyse ne permettra pas d’éviter les contraintes mentionnées ici. Matthieu Auzanneau, directeur du Shift Projet de Jean-Marc Jancovici, a fait une présentation le 7 février 2019 – «This Time the Wolf is Here» – sur la question du pic du…

Naturalist Trip Log, Costa Rica, pt. 2

March 4, 2022 chloevanloon Biology and Life Sciences, Communication, Education and Outreach, Environmental and Earth Sciences

Orchid hunting, bird stalking, and insect photography were just some of the endeavors husband Trevor and I did while traveling around Costa Rica from late 2021 to early 2022. This blog is a trip log of what we got up to, photographs of who we saw, and a few short stories. Instead of a short novel, which I’m prone to write, I decided to organize this blog like a Q & A, hope you enjoy…
