监督与无监督的学习
●Breiman（2001）首先提出了随机森林算法，但基于1995年的Tim Kan Ho●RF采用了两种集合技术：首先是训练样本，以种植基于不同培训训练数据的树木森林。第二个是特征空间的子采样。●如果我选择变量的子集（例如x1, x3, x7) to create a split in a node of a decision tree, and another subset (x2, x4, x5, x7) to create a different one, there will be events that get classified in a different way by the two nodes ● Often there is a dominant variables that is used to decide the split, offsetting the power of the subdominant ones.rf通过减少不同树的相关性来避免该问题

The anatomy of the UC TAP and TAG
The UC TAP tool is designed for use by students transferring from California community colleges, including those students who are seeking a Transfer Admission Guarantee (TAG) with one of the six participating UC campuses. UC TAP is a free online tool to help prospective UC transfer students track and plan their coursework (completed and planned) from the very beginning of their college careers, or at any point when they decide to transfer to a UC campus. It's also a source to receive important messages, not only does it allow UC Staff to communicate important information to prospective transfer students, it's also a way for CCC counselors to communicate with their students and share important information regarding upcoming events/visits from UC representatives. UC TAP streamlines admission and major preparation advising and, Lastly, Academic History on UCTAP can be imported to the UC application
