Principal Component Analysis and Fashion

Any set of images can be broken down with Principal Component Analysis. This has been done pretty successfully with faces. Here we’ll take a look at style.

Our dataset is 807 pictures of dresses from Amazon. They have a standard image size, but unfortunately do not have a standard model pose (though they tend to be centered in the image similarly). Ideally, our principal components would only be about actual dress style, but here many of them will be concerned with model pose. Despite this, we can still do a lot with this data set.

In our deepnightmares, we’ve seen monstrous slugdogs, shoggoths of endless eyes, creatures beyond all reckoning.

Our depiction of the human face hasn’t remained constant, however. Using a technique called face averaging, we can see how the art of the face has evolved.

Settlers of Catan Penrose Tiles

Tired of hexagons? Try playing Settlers of Catan with some Penrose Tiles! Print out as many as you need, then cut along the black lines. When placing tiles (either initial placement or later fog-of-war placement) the little blue and yellow marks MUST match up with the marks of an adjacent tile!
