FGE: An Interpretable Geometric Embedding for Floorplan Similarity and Retrieval

Pick one floorplan: find the most similar ones. Pick two: see where they differ.

Compare two floorplans: A and B, and where they differ

    Adjusting the weights: what counts as similar?

    The weights define what counts as similar: they say which rooms and which descriptors matter, so each set of weights gives other nearest floorplans. Pick a preset, or fine-tune them below.

    The embedding: each plan as a table

    Eight numbers per room: size, shape, position. Rooms of a kind are numbered by size, 1 the largest.

    The difference map

    Difference map: how much A and B differ in each descriptor. Weighted difference map: the same cells times their weights.

    r, ma room (row r) and a descriptor (column m)
    wr, wmthe weight of that room type and of that descriptor (step 5)
    smthe average gap between two random floorplans in that descriptor

    Orientation is compared the short way round the compass. A room that only one plan has counts through its area share and count.

    The difference map: |A − B| ÷ s
