English: Simplified neural network example forobject detection: As seen at the output at right, the network is trained to associate a ringed texture and star outline with astarfish, and a striped texture and oval shape with asea urchin. In this run, it correctly detects the starfish in the input picture at left. In addition, a shell that was not included in the training gives a weak signal for the oval shape, resulting in a weak signal from only one of two intermediate nodes for the sea urchin output, which may still result in afalse positive result (or "hallucination") for sea urchin. In reality, textures and outlines would not be represented by single nodes, but rather by associated weight patterns of multiple nodes.
