Kernel knowledge
The journal Nature demonstrated two principles of journalism recently. The first is that theories about mutant corn plants running amok can garner a great deal of attention. The second is that you can get even more coverage when you declare that you made a mistake and shouldn't have published the paper in the first place. This drama played out over a paper by researchers at UC Berkeley, who rep...
متن کاملKnowledge-Based Kernel Approximation
Prior knowledge, in the form of linear inequalities that need to be satisfied over multiple polyhedral sets, is incorporated into a function approximation generated by a linear combination of linear or nonlinear kernels. In addition, the approximation needs to satisfy conventional conditions such as having given exact or inexact function values at certain points. Determining such an approximati...
متن کاملKnowledge-Based Nonlinear Kernel Classifiers
Prior knowledge in the form of multiple polyhedral sets, each belonging to one of two categories, is introduced into a reformulation of a nonlinear kernel support vector machine (SVM) classifier. The resulting formulation leads to a linear program that can be solved efficiently. This extends, in a rather unobvious fashion, previous work [3] that incorporated similar prior knowledge into a linea...
متن کاملRegularized Knowledge-Based Kernel Machine
This paper presents a knowledge-based kernel classification model for binary classification of sets or objects with prior knowledge. The prior knowledge is in the form of multiple polyhedral sets belonging to one or two classes, and it is introduced as additional constraints into a regularized knowledge-based optimization problem. The resulting formulation leads to a least squares problem that ...
متن کاملPrior Knowledge in Kernel Methods
This thesis explores approaches towards learning with kernel methods using prior knowledge. Invariant learning with kernel methods is considered in more details. In the first part of the thesis, kernels are developed which incorporate prior knowledge on invariant transformations. Next, algorithms which specifically include prior knowledge are considered. An algorithm which linearly classifies d...
