Playground · single-node
Master nodes one at a time
Pick a node, feed it synthetic data, adjust parameters with sliders, and see exactly what it computes — inputs, outputs, and everything in between. Each explorer focuses on one node in isolation.
Kalman 1D filter
Estimate a noisy signal's true value while flagging outliers. Balance smoothing against tracking, set outlier sensitivity, and switch between rejecting spikes and following step changes.
Explore Kalman 1Dkernel
Apply weighted sliding windows to smooth, differentiate, or detect patterns. Pick from built-in presets, switch between test signals, and see the kernel weights alongside the result.
Explore KernelButterworth filter
Remove high-frequency noise with a frequency-domain filter. Adjust the cutoff, choose the filter order, and compare the smoothed output against the raw input.
Coming soonPage-Hinkley
Detect a change in the mean of a streaming signal. Watch the cumulative sum accumulate evidence, then fire when the deviation exceeds a threshold.
Coming soonappraise
Fuse multiple detection signals into a single health assessment. See how evidence from different nodes accumulates, decays, and drives band transitions.
Coming soondwell-time tracker
Measure how long a signal stays in each operating state. Track transitions, count dwell durations, and spot when a process lingers where it shouldn't.
