How do I simulate a clustering model?

Open this page and use the live Logistic Regression tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.

Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.

Can I use my own numbers?

Absolutely — every input is adjustable, and with data import you can drive a clustering model from your own measurements.

Weight w (steepness)

Decision threshold

Logistic regression squashes a linear score through the sigmoid to output a probability between 0 and 1. Predictions above the threshold become one class, below it the other. Raising the weight sharpens the S-curve into a harder decision. Educational tool.

Decision boundary at x0.50

P(class 1 | x=1)0.82

Threshold0.50

Governing equation

p (x) = \frac{1}{1 + e ^{- (- 1.50 + 3.0 x)}} = 0.5 \Rightarrow x^{*} = 0.50

Reading this result: Logistic regression fits this sigmoid by gradient descent on cross-entropy. Weight w=3 sets steepness, bias b=-1.5 shifts the curve, placing the decision boundary at x=0.50 for threshold 0.5.
