我正在尝试使用UCI数据集构建分类器来预测乳腺癌。我正在使用支持向量机。尽管我最真诚的努力提高分类器的准确性,但我无法超过97.062%。我已经尝试了以下方法:
1. Finding the most optimal C and gamma using grid search.
2. Finding the most discriminative feature using F-score.
有人能向我提出提高准确性的技巧吗?我至少要达到99%。
1.Data are already normalized to the ranger of [0,10]. Will normalizing it to [0,1] help?
2. Some other method to find the best C and gamma?
