Abstract: Inverse least squares (ILS) regression is an advancement of classical least squares (CLS) regression, enabling the calculation of concentrations without requiring prior knowledge of the number of components in a mixture. Complex-valued ILS further enhances the performance of ILS by incorporating the complex refractive index function, as demonstrated in the thermodynamically ideal mixtures of benzene–toluene and benzene–cyclohexane. In both systems, the mean absolute error can be reduced by over 50% using the leave-one-out cross-validation (LVOOCV) scheme with complex-valued ILS. Additional error reduction is achievable by leveraging correlations between the errors and the imaginary components of the concentrations or volume fractions. Since the complex refractive index function can be conveniently determined using conventional infrared spectroscopy through the Kramers–Kronig relations, we believe that complex-valued machine learning has the potential to significantly advance analytical applications.

A Least Sandpaper.
I've not posted a #bird #photo for awhile, so here's a #Least #Sandpiper, standing on a little green pile of something (😳) poking up out of the placid surface near the shore of #Frank #Lake, #Alberta 🇨🇦. This bird is slightly larger than a #sparrow. #photography #nature 🪶 #birds #wildlife #cute

Abstract: We present the first implementation of complex-valued classical least squares (CLS) regression in spectroscopy. Although the results indicate that complex-valued CLS does not outperform methods that utilize only the more suitable part of the complex refractive index spectra, it includes an error detection feature that enables a self-correction mechanism. This mechanism decreases the mean absolute error (MAE) to approximately 26% relative to using only the mid-infrared (MIR) absorption index (k) spectra for CLS, and to about 46% relative to using only the MIR refractive index (n) spectra of benzene–toluene mixtures. For benzene–cyclohexane mixtures, the MAE was reduced to approximately 75% relative to the k spectra and 58% relative to the n spectra. In contrast, for benzene–carbon tetrachloride (CCl4) mixtures, i.e., a system that exhibits particularly large deviations from Beer’s law, no improvement over the n spectra was observed; the n-based MAE was 81% relative to the k spectra. These percentages may further vary based on the complexity of the system, the spectral regions selected for CLS and the corresponding deviations from Beer’s approximation.

The original saying attributed (debatably) to Francis of Assisi is "Start doing what is #necessary, then do what is #possible, and suddenly you are doing the #impossible". This has been corrupted in politics to "do the necessary #least of the least, and ignore the rest". @greens.org.au

#Jesus on feeding the #hungry-#RepublicanHypocrites
‘Lord, when did we see you hungry and feed you, or thirsty and give you something to drink?
‘I tell you the truth, whatever you did for one of the #least of these , you did for me.”

Red Eyed Glossy Starling
there's a lot of #birds I have the #least photos of, one of them being the Red Eyed Glossy Starling from the island of Boracay in the Philippines

The #BirdOfTheDay theme today from @alan678.bsky.social is #least and this means the bird in your camera roll that you have the least captures of. Probably this Buff-rumped Warbler from Panamá. Early in the morning, jumping around on the forest floor. Very tricky. #birds #photography

A rose-breasted grosbeak sticks its head out from behind a green bird feeder, facing left. From the feeder, you see its white chest with its bright red breast. It’s neck and head are solid black, while it’s tan beak has a sunflower seed in it. The photo was taken in Walpole MA USA
Among all the birds I photograph in my backyard and in nearby woods and wildlife sanctuaries, the one I’d like to see more, but shows up the #least is the rose-breasted grosbeak. #birds #BirdOfTheDay #grosbeak #nature #birdphotography 🪶

A Northern Flicker looking fancy on a feeder rail
The #BirdOfTheDay theme today is #least, meaning a bird you don’t see very much. It’s always a treat for me to see a #NorthernFlicker. Merlin tells me they’re here far more often than I spot them.

This is the only time I’ve ever seen a merganser. It popped out of the water and I quickly snapped this one. #birdoftheday #least #merganserduck

Barred Owl in a pine tree
Now that I'm home from work, I remembered that I have one more good #BirdOfTheDay for the #least category.
As much as I'm out in nature, and as many pictures as I take, I've very rarely captured images of #owls.
This Barred Owl at a park in San Antonio one morning was a rare exception.

A sunlit bright yellow bird with a large, yellow, conical beak, a bright yellow eye stripe on his dark gray to black head, white wings tipped in black, and a black tail perches on a thin twig with his back to the camera and his head turned to the right against a mottled green and brown background. The sun glints off his black eye, and the downward curve gives him a frowning, imperious look. But, boy oh boy, is he beautiful!
Five (!) years ago this month, a large flock of Evening Grosbeaks descended on our feeders, ate everything they could, and took off, never to be seen again. The one and only time I've ever seen them. It was magical.
