For some applications, it is appropriate to restrict attention to subsequences of characters that occur in precisely the same order in both x and y-- but for other applications this restriction may...
Text Classification using String Kernels (2008)
Huma Lodhi, Craig Saunders, John Shawe-Taylor, Nello Cristianini, Chris Watkins
We propose a novel approach for categorizing text documents based on the use of a special kernel. The kernel is an inner product in the feature space generated by all subsequences of length k. A...
Selective Breeding Analysed as a Communication Channel (2008)
Selective breeding is considered as a communication channel, in a novel way. The Shannon informational capacity of this channel is an upper limit on the amount of information that can be put into the...

Planar Languages and Learnability (2006)
Clark, Alexander, Costa Florencio, Christophe, Watkins, Chris, Serayet, Mariette
Strings can be mapped into Hilbert spaces using feature maps such as the Parikh map. Languages can then be defined as the pre-image of hyperplanes in the feature space, rather than using grammars or...
Languages as Hyperplanes: grammatical inference with string kernels (2006)
Clark, Alexander, Costa Florencio, Christophe, Watkins, Chris
Using string kernels, languages can be represented as hyperplanes in a high dimensional feature space. We present a new family of grammatical inference algorithms based on this idea. We demonstrate...

Background. Inappropriate and costly GP prescribing is a major problem facing Primary Care Trusts. Educational outreach into practices, alongside other measures, such as audit and feedback, have the...
This paper derives a new(?) string kernel based on the discrete Fourier transform. This kernel is rapid to compute, and measures a slightly different kind of similarity from dynamic alignment or...
