How does this work?
The browser loads verified model exports in ONNX format, together with the selected example's original input tensor and fixed target. Each configuration is recomputed on your device. Other cells stay observed while SSI allocates each cell's contrast among its spectral channels. Only the heatmap display is interpolated.
For custom checkpoints, local batch runs or larger workloads, use the Python API. The browser has 57 verified Atlas samples plus a separate bundled HLS example.
Visual Atlas
57 visualizations across six datasets.
For custom models or input images, generate the same figure and numeric results with the Python API.
