Our kaggle competiton paper is here, to facilitate automatic plant classification utilizing digitized plant specimens at @NYBGHerbarium and five other institutions. We are preparing for a new kaggle competition for 2022, harnessing images from 50 institutions around the world.

Highlight of this week: From a class project for Fundamentals of Machine Learning class. Letters 'a' and 'b' segregate nicely on the PC axes. Plus note the PC1 eigenvector! It clearly shows that the shape differences between a and b are the major source of variation.

Current status: 25 reviewer invites sent 😩 & 1 acceptance!

Reviewing papers is unpaid/undervalued & part of a broken publishing system, but editors will need to find someone to review YOUR paper...do us a favor and review someone else's paper...

If you stay in academia (or most careers) there will always be the guilt of “I could have done better.”

I channel this into drive to do even better next time, and I let go of the guilt by recognizing that putting more time into the last goal would take away from future goals.

[Jen Heemstra @jenheemstra]

At the heart of good time management is the realization that every "yes" is a "no" to something else. Before you commit time to do something, ask yourself what you will have to not do as a result. Then ask yourself whether that is a trade worth making.

Indiana will see a dramatic increase in dangerously hot days over the next few decades, even if the Paris Agreement's goals are met. If these goals aren't met, summer conditions will become progressively more dangerous. Are we protecting the vulnerable? https://t.co/KQLaU5KRWK

Vertical leaf structure in tropical forests.

-Temp. and precip. explains 50% of #ANPP variation among lowland tropical rain forests.

-Vertical leaf area profile explains another 38% of the variation.
