To us this was an amusing correlational study in the spirit of McKeown and Illich—those sceptics of medical prowess. That our work has been reprinted in two collections of ep...

A 28-year-old woman presented with an erythematous rash involving the nose, nasolabial folds, and philtrum that appeared after she had manipulated a painful vesicular lesion at the base of her nose that she believed to be a pimple.

Parity: The Problem that Won't Go Away

It is well-known that certain learning methods (e.g., the per-ceptron learning algorithm) cannot acquire complete, parity mappings. But it is often overlooked that state-of-the-art learning methods such as C4.5 and backpropagation cannot generalise from incomplete parity mappings. The failure of such methods to generalise on parity mappings may be sometimes dismissed on the grounds that it isìm...
