Artifact Gallery

The Artifact Gallery displays the files stored under the study's artifacts/ folder (loaded with the Artifacts toolbar button), associating each file with its trial and with analysis results.

View modes

• All: every trial that has artifacts, shown as a paginated thumbnail grid (sorted by trial ID).
• By Cluster: runs k-means clustering with the settings you choose (k / target space / selection mode / init) and groups the artifacts into a collapsible section per cluster.
• By MCDM Rank: runs the selected MCDM method and lists the artifacts in ranking order (top-N), with the rank and score shown on each card.

When a trial has multiple artifacts, the Artifact # selector chooses which one (0-based) is shown per trial, so each trial contributes a single card. Trials that don't have an artifact at the selected index are skipped.

Image files (PNG / JPEG / GIF / WEBP) are shown as thumbnails; clicking a thumbnail opens a large preview in a modal (close with the button, Esc, or by clicking outside). Other files (CSV, etc.) show an icon and an Open button that opens the file with the system default application. Clicking a card highlights the corresponding trial across the other widgets. Each card also shows the trial's objective values so you can judge the result without opening the file.

Comparing settings (A vs B)

Clustering and MCDM results are cached per setting. To compare, for example, k = 3 against k = 5, place two Artifact Gallery widgets on the canvas and give each its own setting — they read the result for their own setting from the shared cache, so both configurations can be viewed side by side. A setting already computed by another Clustering / MCDM widget is reused instantly; an uncomputed setting can be run from the gallery itself with Run.
