How a machine learns

The line that follows the data

For a machine, learning means finding the numbers that make it wrong as little as possible. Here there is only one: the slope $w$ of the line $y = wx$ , which must pass as close as possible to six points.

For each point we take the residual, how far the point lies above or below the line. The error is the mean of the squared residuals:

L(w) = \frac{1}{n}\sum_{i=1}^{n} \left(y_i - w\,x_i\right)^2

where $(x_i,\,y_i)$ are the points and $n$ is how many there are.

Drag the line or the point on the curve: the error changes with w.

Try it

Exercise

With the line $y = x$ and the two points $(1,\,1)$ and $(2,\,3)$ , what is the error $L$ ?

0.5Check

Correct!

The residuals

$1 - 1 = 0 \qquad 3 - 2 = 1$

The mean of the squares

$L = \tfrac{0^2 + 1^2}{2} = 0.5$

Problems and solutions, step by step.

New variants whenever you want, each one checked automatically.

Exercise

Solve $2(x - 3) = x + 4$ .

How we built PrismaX.

A first call to the model plans the request in JSON; the next ones write the lesson, the figure and the exercises. The code runs in an isolated sandbox and, if it fails, goes back to the model with the error.

Course licenses

PrismaX for everyone enrolled and every teacher in the course, with restricted access and results by student and by exercise. For companies too, with seats for in-house trainers.

We start with a pilot on one class.

Turnkey interactive module

We build it for you: animations, exercises with automatic checking, an entry and a final test, with your brand.

What do you want to change or add?

Workshop

Creating interactive lessons with AI: hands-on training for teachers and trainers, with one year of access included.

More courses and sites? Contracts with your brand only and a dedicated contact person.

AI agents

We also build agents, data analysis and products on request, with processes and technologies similar to those we used to build PrismaX.
