A Sequential Model for Multi-Class Classification
Many classification problems require decisions among a large number of competing classes. These tasks, however, are not handled well by general purpose learning methods and are usually addressed in an ad-hoc fashion. We suggest a general approach – a sequential learning model that utilizes classifiers to sequentially restrict the number of competing classes while maintaining, with high probabil...
متن کاملQuestion classification based on an extended class sequential rule model
Question classification is a crucial preprocessing for question answering system; it can help to make sure the user’s intention. Most of previous researches focus on the feature driven methods that represent a question with a bag of features, which ignore the important information contained in the words order and distance. To take such information into account, this paper proposes to describe t...
متن کاملLearning for Sequential Classification
In many computer vision classification problems, both the error rates and the evaluation time characterises the quality of a decision. Yet most of the learning algorithms do not optimise the evaluation time explicitly. We show that such learning problems can be formalised in the framework of sequential decision-making. The proposed formalisation has been already studied (without learning) by Wa...
متن کاملSequential Land Cover Classification
Land cover classification using remotely sensed data is a critical first step in large-scale environmental monitoring, resource management and regional planning. The classification task is made difficult by severe atmospheric scattering and absorption, seasonal variation, spatial dependence, complex surface dynamics and geometries, and large intra-class variability. Most of the recent research ...
متن کاملSequential Feature Selection for Classification
In most real-world information processing problems, data is not a free resource; its acquisition is rather time-consuming and/or expensive. We investigate how these two factors can be included in supervised classification tasks by deriving classification as a sequential decision process and making it accessible to Reinforcement Learning. Our method performs a sequential feature selection that l...
