What if I told you a neural network understands local change before it understands the full picture?
That idea is deeply connected to something called the Jacobian Matrix.
At first, it looks terrifying. A big matrix full of partial derivatives. But the intuition behind it is actually beautiful.
The Jacobian measures how small changes in input variables affect the output of a system.
Imagine slightly changing the pixels of an image.
Or changing one feature in a dataset.
How much does the prediction change?
The Jacobian tells us exactly that.
You can think of it as a “sensitivity map” for transformations.
If a system transforms one space into another, the Jacobian describes how the geometry changes locally.
Tiny squares can stretch, rotate, compress, or skew into completely different shapes.
That is why Jacobians are everywhere in AI & machine learning.
For example:
- Backpropagation relies heavily on Jacobians through the chain rule
- Neural networks use them to understand gradient flow
- Normalizing Flows use Jacobian determinants for probability density transformations
- Computer Vision uses them in geometric warping and image alignment
- Robotics uses Jacobians for motion and control systems
- Diffusion models and generative models often depend on transformations between latent spaces
The interesting part is this:
Most ML models are basically learning transformations.
And the Jacobian is what tells us how those transformations behave locally.
Step-by-step intuition:
- Start with an input vector
- Apply a transformation
- Measure how each output changes with respect to each input
- Store those local relationships inside a matrix That matrix becomes the Jacobian.
Carl Gustav Jacob Jacobi introduced this mathematical idea long before AI existed.
But today, modern deep learning silently runs on top of concepts like this every second.
Sometimes the most important parts of AI are not the flashy models.
They are the mathematical structures underneath them.

$15 IPO. $126 first-day close. 700% in 10 minutes. The biggest manipulated bubble in modern history
Bookmark this PBS Frontline documentary - it's the cleanest case of "Reflexivity" bias ever caught on camera. Wall Street didn't watch the bubble happen
They built it, and
priced the shares, picked the buyers, and pocketed the gap
1996 to 2000. Goldman, Morgan Stanley, Credit Suisse First Boston took companies public with no revenue, no product, sometimes no working website. The narrative did the rest: "this is the new economy, the old rules don't apply."
The price obeyed the narrative. IPOs priced at $15 traded at $126 within hours. The funds that got pre-allocated shares flipped them in minutes. Retail bought the top. Analysts publicly called the same stocks "buy" while privately calling them "junk."
Reflexivity is when the price stops measuring reality and starts writing it. Up means right. Right means more buyers. More buyers means up. Each turn convinces the next round that the previous round wasn't crazy
By 2000, companies were adding ".com" to their name and watching their stock jump for it. Same business, new ticker, new valuation. Then insiders started selling. The story unwound faster than it built. Retail held the bag
Reflexive bubbles end when the loop runs out of new people to convince. Not before. Not after
Reflexivity is the last bias in the iceberg - and the hardest to see until it collapses ↓

Everyone can have a try at Pick n Pay... It's like internship for Anyone who wants to try and run a company 🤣🤞🤞
I am thinking of having a Go at it aswel lol

@BusinessTechSA And Gentz this is another illustration of what being "Trapped" means
Boxer a world class asset trapped in a failing structure
But Boxer knew before hand that Pick n Pay if it picks it will pay

Pick n Pay has recorded a R185 million loss for the 2026 financial year, with the group benefitting from the strong performance of Boxer. businesstech.co.za/news/business/… businesstech.co.za/news/business/…

Dear Fellow South African,
As we mark 30 years this month since the adoption of our country’s constitution, we can reflect with pride on political culture we have built as a nation – a culture that is robust, participatory, continuously evolving and firmly anchored in the democratic values we hold dearly.
