What would happen, so I asked myself, when instead of just latitute and longitude I would use population as a third dimension? How would the similarity search turn out? The experiments proofed to be quite interesting. And it turned the focus on the aspect that the way embeddings are generated, turning objects into vector data, has a significant impact on result quality and usefulness.</p>
