🥳 Wow, someone finally found a way to make #mathematics sound like a #household chore. "Matryoshka vs. PCA" sounds like the title of a bad sitcom where nobody laughs, but at least we learn that shrinking #embeddings is as exciting as watching paint dry. 📉🔍

Pete Crow-Armstrong is projected to have something like 192 more plate appearances in the regular season. There are projections for how he will finish the year, but they all assume regression. Which... fair. But I was curious what it would look like if PCA stayed hot.

What if PCA's next 192 PA were exactly like his last 192?

I crunched the numbers and got this:

.295/.398/.572 triple slash. 37 HR, 42 SB, 95 BB, 115 R, 101 RBI, wRC+ of 166, 11.2 fWAR.

Y'all that fWAR total would be better than Mike Trout's best season.

Evaluation of concentrations of 35 PCB congeners in blood of about 5,000 individuals in the U.S. in 2003-2004 identified variations in PCB fingerprints by age, with a distinct pattern in a subset of younger individuals.

UMAP, t-SNE, and PCA were used for dimensionality reduction and pattern analysis. UMAP proved best at clustering data points with similar fingerprints.

Richard Salter Storrs, Congregationalist, says the gospel endeared respect for lives and property of others, lessened internecine wars, increased compassion for sick & ship-wrecked Mariners. It “constrained” people to divide their last morsel with famished travelers.

Would those who claim to be “men of God” today, instead, warn you about sick travelers out to constrain UR family to a single morsel?

How can you live out these ideals?

Result of a Principal Component Analysis (PCA) created from combined median composites of Sentinel-1 and Sentinel-2 imagery — somewhere in the Sudanese desert.

This PCA composite brings out contrasts between lithologies, structural domains, drainage patterns, and surface materials, highlighting features that are nearly invisible in standard RGB representations.

And yes — it also happens to look stunning.

Exploring large-scale landscape structures with a simple Principal Component Analysis (PCA) applied to a MODIS composite.

The PCA reveals striking contrasts in surface materials, vegetation patterns, and terrain transitions across western Canada — from the Rocky Mountains into the prairies and the Canadian Shield.
Even with moderate-resolution MODIS data, spectral variability produces a surprisingly rich view of regional geography and geomorphology.

Result of a Principal Component Analysis (PCA) based on combined median composites of Sentinel-1 and Sentinel-2 satellite imagery — somewhere in the desert of Sudan.

The PCA highlights contrasts between different lithologies, structural domains, and surface materials, revealing subtle geological features that are hard to distinguish in standard RGB composites.

And yes — it also looks simply beautiful.

Behind the scenes of “beautiful scientific graphics”

If you think that clean, elegant visuals in scientific reports are produced in a couple of clicks — I’m here to disappoint you. 🙂

Here’s one of many failed attempts to visualize results based on thermodynamic modeling of geochemical processes.

Turning raw multidimensional data into something that a human reader can intuitively grasp is a separate challenge — with dozens of input parameters and only a few truly useful outcomes.

Good science is not only about computation, but also about communication.

🛰️ Today I’m sharing one of my favourite large-scale remote sensing experiments:
a Principal Component Analysis (PCA) of MODIS composite data for the three central provinces of Canada (Alberta, Saskatchewan, Manitoba).

On this map:
- PC1 emphasizes broad ecological zones and vegetation productivity
- PC2 highlights soil and surface moisture differences
- PC3 captures subtle spectral variations — often linked to geology, wetlands, disturbance patterns, or local microclimates

Even though it looks abstract, PCA is a kind of “spectral fingerprint” of the land. It summarises thousands of square kilometres into a single visual structure that shows how the Canadian Prairies and Boreal regions differ and transition into one another.
