Appropriate Kernel Functions for Support Vector Machine Learning with Sequences of Symbolic Data, certain circumstances. This latter approach first transforms symbolic data to vectors of numerical data which are then used as arguments for one of the standard kernel functions. In contrast, we will propose kernels that operate on the symbolic data directly.

Extensions of the Informative Vector Machine,, we use IVM on a block-diagonal covariance matrix, for “l(fā)earning to learn” from related tasks. Third, we modify the IVM to incorporate prior knowledge from known invariances. All of these extensions are tested on artificial and real data.

Ensemble Algorithms for Feature Selection,ce intervals to control the rate of convergence. A feature selection threshold is also derived, using the expected performance of an irrelevant feature. Experiments demonstrate the potential of these methods and illustrate the need for both feature weighting and selection.

Variational Bayes Estimation of Mixing Coefficients, normal with the same mean but a different covariance matrix compared with those for the maximum likelihood estimator. Furthermore we prove that the covariance matrix from the variational Bayes approximation is ‘too small’ compared with that for the MLE, so that resulting interval estimates for the parameters will be unrealistically narrow.

A Comparison of Condition Numbers for the Full Rank Least Squares Problem,ded that the solution . . of the LS problem may be well-conditioned in the normwise sense, even if one of its components is ill-conditioned. It is shown that the refined condition numbers are ill-conditioned in some circumstances, the cause of this ill-conditioning is identified, and its implications are discussed.

SVM Based Learning System for Information Extraction, statistical learning algorithms) on three IE benchmark datasets: CoNLL-2003, CMU seminars, and the software jobs corpus. The experimental results show that our system outperforms a recent SVM-based system on CoNLL-2003, achieves the highest score on eight out of 17 categories on the jobs corpus, and is second best on the remaining nine.

無王時(shí)期,

Genetics of the Immune Response for uniform input densities, but we also discuss the generalization to the non-uniform case. We show further that the equivalent kernel can be used to understand the learning curves for Gaussian processes, and investigate how kernel smoothing using the equivalent kernel compares to full Gaussian process regression.

Molecular Analyses of MHC Antigens may be achieved in a mathematically elegant manner. In this paper we extend the general ICA paradigm to include a very flexible source model and prior constraints and argue that for particular biomedical signal processing problems (we consider EEG analysis) we require the constraint of . in the mixing process.
