Visual Data Lab

time series

See how AR and MA settings change a simulated time series and its autocorrelation patterns.

Bias-Variance Tradeoff

statistics

regression

Use an interactive smoother to see how model flexibility changes underfitting, overfitting, train error, and test error.

Decision Tree

classification

Build synthetic classification data and watch a decision tree carve the feature space into regions.

Dimensionality Reduction

mathematics

Compare PCA, Isomap, t-SNE, and UMAP on simulated and real high-dimensional datasets.

K-means Step by Step

clustering

Move through each K-means iteration to see centers, assignments, and convergence on generated clusters.

K-means on Images

clustering

Apply K-means to image colors and compare the original image with a compressed color version.

Logistic Regression

classification

regression

Change noise, polynomial terms, and class structure to see how logistic regression shapes decision boundaries.

Lorenz Attractor

mathematics

Adjust the Lorenz parameters and watch how small changes produce chaotic 3D trajectories.

Matrix Decompositions
