RandomForest(随机森林)LeoBreiman1928--2005相关资料Breiman,Leo."Randomforests." Machinelearning 45.1(2001):5-32.http:///users/breiman/RandomForests随机森林树算法是一种组合多个树分类器进行分类的方法。其基本思想是每次随机选取一些特征,独立建立树,重复这个过程,
Our algorithm can more accurately predict distri-butions over such labels compared to severalcompetitive baselines. 本文介绍了一种新颖地基于递归自动编码器机器学习框架,用于句子级地情感标签分布预测。 本文的方法学习多词短语的向量空间表示。在情感预测任务中,这些表示优于常规数据集(例如电影评论)上的其他...

much smaller data size. With EFB, we bundle mutually exclusive features (i.e., they rarely take nonzero values simultaneously), to reduce the number of features. We prove that finding the optimal bundling of exclusive features is NP-hard, but a greedy algorithm can achieve quite good ...
Our algorithm can more accurately predict distri-butions over such labels compared to severalcompetitive baselines. 提出了一种基于递归自动编码器的句子级情绪标签分布预测机器学习框架。我们的方法学习多词短语的向量空间扫描。在情绪预测任务中,这些代表在不使用任何预定义的情绪词汇或极性转换规则的情况下,在...
