摘要:

在这项工作中,我们解决了使用得分函数组合线性分类器的问题。评分函数的值取决于与决策边界的距离。两个得分函数进行了测试,并研究了四种不同的组合策略。在实验研究中,将该方法应用于异构集成,并与两种参考方法--多数投票法和模型平均法进行了比较。根据七个不同的质量标准进行了比较。结果表明,基于简单平均和修剪平均的组合策略是几何组合的最佳组合策略。

英文摘要:

In this work, we addressed the issue of combining linear classifiers using their score functions. The value of the scoring function depends on the distance from the decision boundary. Two score functions have been tested and four different combination strategies were investigated. During the experimental study, the proposed approach was applied to the heterogeneous ensemble and it was compared to two reference methods -- majority voting and model averaging respectively. The comparison was made in terms of seven different quality criteria. The result shows that combination strategies based on simple average, and trimmed average are the best combination strategies of the geometrical combination.
