之前我们提到过一个概念,Classification and Regression Tree(CART)的概念。前面两篇文章我们提到了Decision Tree - Regression。 今天我将给大家讲一下Classification Decision Tree. 本文将会讲到一个熵(entrop…

● 信息增益（Information Gain）：选择某一特征进行划分后，数据集的不确定性降低的程度。信息增益越大，说明该特征对划分数据集、减少不确定性的作用越强。● 基尼指数（Gini Impurity）：另一种衡量数据集纯度的指标，越小表示纯度越高。在CART（Classification and Regression Tree）算法中，基尼指数常用于替代信息...
Classification is a two-step process; a learning step and a prediction step. In the learning step, the model is developed based on given training data. In the prediction step, the model is used to predict the response to given data. A Decision tree is one of the easiest and most popular...

The current paradigm in parsing has been developed primarily using English, a language that relies on word order to express grammatical function. However, most languages in the world rely much more on NP-marking to express the same functions. We propose therefore a shallow NP parsing technique wh...
