经过数据加载步骤后,数据没有刺头了变得规规矩矩了,哪一块就是哪一块,但是都是numpy,series,dataframe等数据格式,而深度学习框架只认识张量(tensor)数据格式,在PyTorch的世界,不管是模型的输入,输出还是模型的参数都是由tensor来编码的,所以我们需要将之前得到的dataframe转化为tensor,并适当的分组(batch)以便输入模型...

使用RandomForest进行K-折交叉验证 随机森林(Random Forest)是一种集成学习算法,可以用于分类和回归问题。它结合了多个决策树(即“森林”)来进行预测,通过对决策树的结果进行投票或平均来得到最终的预测结果。随机森林具有以下特点和优势: 特点: 随机性:随机森林在每个决策树的构建过程中都引入了随机性,包括随机选择特...

(NRS), a novel deep learning based random subspace method. In contrast to previous forest methods, NRS enjoys the benefits of end-to-end, data-driven representation learning, as well as pervasive support from deep learning software and hardware platforms, hence achieving faster inference speed and...
